Obesity, a chronic health condition, develops gradually as excess body fat accumulates and may pose health risks. Defined by the Centers for Disease Control and Prevention (CDC) as having a Body Mass Index (BMI) of 30 or higher, obesity is associated with serious diseases such as type 2 diabetes, heart disease, and cancer.
While BMI is commonly used as a screening tool for obesity, it has limitations. Factors like age, sex, ethnicity, and muscle mass can influence its accuracy, and it doesn’t differentiate between types of body mass. Nevertheless, due to its affordability, BMI remains widely employed for measuring body size.
Furthermore, weight discrimination can exacerbate the negative health impacts of obesity. In the United States, obesity rates have surged, affecting 41.9% of the population from 2017 to March 2020, as per CDC estimates.
Exploring the causes, risk factors, and treatment options for obesity can provide deeper insights into managing and combating this prevalent health issue.

What are the symptoms of obesity?
Recognizing the symptoms of obesity is crucial for early intervention and management. While the most apparent sign is excessive body weight, there are other symptoms and indicators to consider.
- Weight Gain: The primary symptom of obesity is noticeable weight gain, often accompanied by an increase in body fat percentage. This weight gain may occur gradually over time and can lead to significant health concerns if left unaddressed.
- Body Mass Index (BMI): Calculating BMI, a measure of body fat based on height and weight, can indicate whether an individual falls within a healthy weight range or is overweight or obese. A BMI of 30 or higher typically indicates obesity.
- Increased Waist Circumference: Excess fat around the waistline, often referred to as abdominal obesity or visceral fat, is a common symptom of obesity. A waist circumference greater than 35 inches for women and 40 inches for men may indicate an increased risk of obesity-related health issues.
- Breathlessness: Obesity can lead to reduced lung capacity and shortness of breath, particularly during physical activity or when exerting oneself. This symptom may indicate that excess weight is placing strain on the respiratory system.
- Fatigue: Carrying excess weight can lead to feelings of fatigue and low energy levels. Obesity-related fatigue may be exacerbated by poor sleep quality, sleep apnea, or other sleep disorders commonly associated with obesity.
- Joint Pain: Excess weight places added pressure on the joints, particularly the knees, hips, and lower back. Individuals with obesity may experience chronic joint pain or discomfort, which can hinder mobility and reduce quality of life.
- Skin Issues: Obesity can contribute to skin conditions such as stretch marks, skin tags, and acanthosis nigricans, a darkening and thickening of the skin in body folds and creases. These skin changes may be indicative of insulin resistance and metabolic dysfunction.
- Psychological Symptoms: Obesity can also impact mental health, leading to symptoms such as depression, anxiety, low self-esteem, and body image dissatisfaction. These psychological effects may further contribute to unhealthy eating habits and sedentary behavior, perpetuating the cycle of obesity.
Recognizing these symptoms is essential for early intervention and proactive management of obesity. If you or someone you know is experiencing these symptoms, it’s important to consult with a healthcare professional for personalized guidance and support. Addressing obesity through lifestyle modifications, dietary changes, physical activity, and medical interventions can help improve overall health and reduce the risk of obesity-related complications.
How is obesity classified?
Obesity is classified using various methods, each providing insight into an individual’s weight status and associated health risks. These classifications are based on measurements such as Body Mass Index (BMI), waist circumference, and other factors. Here are the primary classifications of obesity:
- Body Mass Index (BMI):
BMI is a widely used measurement that calculates an individual’s body fat based on their height and weight. The formula for BMI is weight in kilograms divided by height in meters squared (BMI = kg/m^2). The World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC) classify BMI into several categories:
- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obesity (Class 1): BMI between 30 and 34.9
- Obesity (Class 2): BMI between 35 and 39.9
- Extreme obesity (Class 3): BMI 40 or higher
- Waist Circumference:
Waist circumference is another important measurement used to assess abdominal obesity, which is particularly associated with increased health risks. Excess fat around the waistline, known as visceral fat, can indicate a higher risk of obesity-related complications such as cardiovascular disease and type 2 diabetes. Classification thresholds for waist circumference vary by gender and ethnicity but generally indicate increased risk if:
- For men, waist circumference is greater than 40 inches (102 cm)
- For women, waist circumference is greater than 35 inches (88 cm)
- Waist-to-Hip Ratio (WHR):
The waist-to-hip ratio is another measurement used to assess fat distribution and overall health risk. It compares the circumference of the waist to that of the hips. A higher ratio indicates a greater accumulation of abdominal fat and is associated with increased risk of obesity-related diseases. - Other Factors:
In addition to BMI and waist circumference, other factors such as body composition, fat distribution, metabolic health, and presence of comorbidities (such as diabetes, hypertension, and cardiovascular disease) are considered when classifying obesity and determining its impact on an individual’s health.
Classifying obesity is essential for identifying individuals at risk of obesity-related complications and guiding appropriate interventions and treatments. Healthcare professionals use a combination of these measurements and factors to assess obesity and develop personalized strategies for weight management and improving overall health.
What is childhood obesity?
Childhood obesity refers to a medical condition characterized by excess body fat in children and adolescents. It is a serious and complex issue with significant implications for both immediate health and long-term well-being. Childhood obesity is typically assessed using growth charts and percentile rankings based on age and gender-specific BMI values. Here’s a deeper look into childhood obesity:

Addressing obesity requires a comprehensive approach that addresses the complex interplay of genetic, environmental, behavioral, and socioeconomic factors. Strategies focused on promoting healthy eating habits, increasing physical activity, creating supportive environments, and addressing inequities are essential for preventing and managing obesity on individual, community, and societal levels.
Who is at risk of obesity?
Obesity can affect individuals of all ages, genders, and socioeconomic backgrounds, but certain factors increase the risk of developing obesity. Identifying these risk factors is essential for targeted prevention and intervention efforts. Here’s an overview of populations at higher risk of obesity:
- Genetic Predisposition:
Individuals with a family history of obesity are more likely to develop obesity themselves. Genetic factors can influence metabolism, fat storage, appetite regulation, and other physiological processes related to weight gain. - Socioeconomic Status:
Socioeconomic disparities play a significant role in obesity risk. People from low-income households may face barriers to accessing nutritious foods, safe recreational spaces, and healthcare services. Additionally, economic stressors may contribute to unhealthy eating habits and sedentary lifestyles. - Dietary Habits:
Poor dietary habits, such as consuming a diet high in calorie-dense, processed foods, sugar-sweetened beverages, and fast food, increase the risk of obesity. Lack of access to fresh fruits, vegetables, and whole grains can also contribute to unhealthy eating patterns. - Physical Activity Levels:
Sedentary lifestyles characterized by minimal physical activity or exercise are associated with a higher risk of obesity. Lack of opportunities for physical activity, such as limited access to parks, sidewalks, and recreational facilities, can contribute to sedentary behavior. - Age and Gender:
While obesity can occur at any age, the risk tends to increase with age, peaking in middle age and declining in older adulthood. Additionally, gender can influence obesity risk, with women being more likely to experience obesity compared to men in some populations. - Psychological Factors:
Psychological factors such as stress, depression, anxiety, and emotional eating can contribute to obesity risk. Coping mechanisms involving food, as well as maladaptive behaviors related to body image and self-esteem, may influence eating habits and weight management. - Medical Conditions and Medications:
Certain medical conditions, such as hypothyroidism, polycystic ovary syndrome (PCOS), and hormonal imbalances, can predispose individuals to weight gain and obesity. Additionally, some medications, such as antidepressants, antipsychotics, and corticosteroids, may cause weight gain as a side effect. - Environmental Factors:
Environmental influences, including neighborhood characteristics, access to healthy foods, food marketing, and built environments, can impact obesity risk. Living in neighborhoods with limited access to fresh, affordable foods and few opportunities for physical activity can contribute to higher obesity rates.
Identifying individuals at higher risk of obesity allows for targeted interventions and public health initiatives aimed at addressing the underlying factors contributing to weight gain. Prevention efforts focused on promoting healthy eating habits, increasing physical activity, and creating supportive environments are essential for reducing obesity prevalence and improving overall health outcomes.
How is obesity diagnosed?
Diagnosing obesity typically involves a combination of assessments, measurements, and evaluations to determine an individual’s weight status and associated health risks. Healthcare professionals use various methods to diagnose obesity, including:
- Body Mass Index (BMI):
BMI is a widely used measurement that calculates an individual’s body fat based on their height and weight. The formula for BMI is weight in kilograms divided by height in meters squared (BMI = kg/m^2). Healthcare providers use BMI to categorize weight status into different classifications:
- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obesity (Class 1): BMI between 30 and 34.9
- Obesity (Class 2): BMI between 35 and 39.9
- Extreme obesity (Class 3): BMI 40 or higher
- Waist Circumference:
Measuring waist circumference provides additional information about abdominal obesity, which is associated with increased health risks. Excess fat around the waistline, known as visceral fat, can indicate a higher risk of obesity-related complications such as cardiovascular disease and type 2 diabetes. Healthcare providers typically measure waist circumference at the midpoint between the lower margin of the last rib and the top of the iliac crest. - Medical History and Physical Examination:
Healthcare providers conduct a comprehensive medical history and physical examination to assess risk factors for obesity and obesity-related complications. This includes evaluating family history, lifestyle habits, dietary patterns, physical activity levels, and any underlying medical conditions or medications that may contribute to weight gain. - Laboratory Tests:
In some cases, healthcare providers may order laboratory tests to assess metabolic health and screen for obesity-related complications. These tests may include:
- Lipid profile: Measures cholesterol and triglyceride levels in the blood.
- Fasting glucose or hemoglobin A1c (HbA1c): Tests for diabetes or impaired glucose tolerance.
- Liver function tests: Assess liver health and screen for non-alcoholic fatty liver disease (NAFLD).
- Thyroid function tests: Evaluate thyroid hormone levels to rule out thyroid disorders that may affect metabolism.
- Additional Assessments:
Depending on individual risk factors and clinical presentation, healthcare providers may recommend additional assessments such as body composition analysis, metabolic testing, or screening for obesity-related comorbidities such as hypertension, sleep apnea, and musculoskeletal issues.
Diagnosing obesity involves a comprehensive evaluation of multiple factors, including BMI, waist circumference, medical history, physical examination, and laboratory tests. This holistic approach allows healthcare providers to accurately assess weight status, identify associated health risks, and develop personalized strategies for obesity management and prevention.
What are the complications of obesity?
Obesity is associated with a wide range of complications that can affect nearly every organ system in the body. These complications can have profound effects on health, quality of life, and overall well-being. Here are some of the most common complications of obesity:
- Type 2 Diabetes:
Obesity is a major risk factor for developing type 2 diabetes. Excess body fat, particularly abdominal fat, can lead to insulin resistance, where the body’s cells become less responsive to insulin. This can result in high blood sugar levels and eventually lead to diabetes if left unmanaged. - Cardiovascular Disease:
Obesity increases the risk of developing various cardiovascular conditions, including:
- Hypertension (high blood pressure)
- Coronary artery disease (heart disease)
- Stroke
- Heart failure
- Atherosclerosis (hardening of the arteries)
- Peripheral artery disease (narrowing of blood vessels in the limbs)
- Dyslipidemia:
Obesity is often accompanied by abnormal lipid levels in the blood, including elevated triglycerides, LDL cholesterol (bad cholesterol), and decreased HDL cholesterol (good cholesterol). Dyslipidemia is a significant risk factor for cardiovascular disease and other obesity-related complications. - Non-alcoholic Fatty Liver Disease (NAFLD):
NAFLD is a condition characterized by the accumulation of fat in the liver, not due to excessive alcohol consumption. Obesity, particularly abdominal obesity, is a primary risk factor for NAFLD, which can progress to more severe liver conditions such as non-alcoholic steatohepatitis (NASH) and cirrhosis. - Sleep Apnea:
Obesity increases the risk of obstructive sleep apnea, a sleep disorder characterized by repetitive pauses in breathing during sleep. Excess fat around the neck and throat can obstruct the airway, leading to disrupted sleep patterns, daytime fatigue, and an increased risk of cardiovascular complications. - Joint Pain and Osteoarthritis:
Excess weight places added pressure on the joints, particularly the knees, hips, and lower back. Obesity is a significant risk factor for osteoarthritis, a degenerative joint disease characterized by pain, stiffness, and decreased mobility. - Respiratory Issues:
Obesity can impair lung function and respiratory mechanics, leading to conditions such as:
- Asthma
- Chronic obstructive pulmonary disease (COPD)
- Obesity hypoventilation syndrome (OHS)
- Decreased exercise tolerance and breathlessness
- Cancer:
Obesity is associated with an increased risk of several types of cancer, including breast cancer, colorectal cancer, endometrial cancer, and kidney cancer. The mechanisms underlying this association may involve chronic inflammation, hormonal imbalances, and metabolic dysregulation. - Psychological and Social Complications:
Obesity can have significant psychological and social consequences, including:
- Depression
- Anxiety
- Low self-esteem
- Body image dissatisfaction
- Social stigmatization and discrimination
These complications highlight the profound impact of obesity on health and well-being. Preventing and managing obesity requires comprehensive strategies that address underlying factors, promote healthy behaviors, and support individuals in achieving and maintaining a healthy weight. Early intervention and proactive management are essential for reducing the risk of obesity-related complications and improving overall health outcomes.
How is obesity treated?
Treating obesity requires a multifaceted approach that addresses the complex interplay of genetic, environmental, behavioral, and socioeconomic factors contributing to weight gain. Effective obesity treatment involves a combination of lifestyle modifications, dietary changes, physical activity, behavioral interventions, and, in some cases, medical or surgical interventions. Here are some key components of obesity treatment:

These medications may work by suppressing appetite, reducing absorption of nutrients, or increasing feelings of fullness. It’s important to use weight loss medications under the supervision of a healthcare professional and in conjunction with lifestyle modifications.
- Weight Management Programs: Comprehensive weight management programs may include structured meal plans, behavioral counseling, exercise programs, and medical supervision to support individuals in achieving and maintaining weight loss goals.
- Surgical Interventions:
- Bariatric Surgery: Bariatric surgery may be recommended for individuals with severe obesity or obesity-related health complications who have not achieved adequate weight loss with nonsurgical interventions. Bariatric procedures, such as gastric bypass, sleeve gastrectomy, and gastric banding, work by reducing the size of the stomach or altering the digestive tract to limit food intake and promote weight loss.
- Psychological Support:
- Counseling and Therapy: Psychological support is integral to obesity treatment, particularly for addressing emotional eating, body image issues, and underlying psychological factors contributing to weight gain. Counseling, therapy, and support groups can help individuals develop healthier attitudes towards food, body image, and self-care.
- Long-Term Maintenance:
- Follow-Up Care: Long-term maintenance of weight loss requires ongoing monitoring, support, and follow-up care from healthcare professionals. Regular check-ins, dietary counseling, physical activity recommendations, and adjustments to treatment plans may be necessary to sustain weight loss and prevent relapse.
Treating obesity is a long-term commitment that requires dedication, patience, and support from healthcare professionals, family members, and community resources. By addressing the underlying factors contributing to weight gain and implementing evidence-based interventions, individuals can achieve sustainable weight loss, improve overall health, and reduce the risk of obesity-related complications.
Which lifestyle and behavioral changes can help with weight loss?
Lifestyle and behavioral changes are fundamental for successful weight loss and long-term weight management.

Which medications are prescribed for weight loss?
Several medications may be prescribed by healthcare professionals to aid in weight loss efforts, particularly for individuals who have not achieved adequate results with lifestyle modifications alone. These medications are typically recommended as part of a comprehensive weight management plan and are intended for use in conjunction with a reduced-calorie diet and increased physical activity. It’s important to note that weight loss medications are not suitable for everyone and should be used under the supervision of a healthcare provider. Here are some commonly prescribed medications for weight loss:
- Orlistat (Xenical, Alli):
Orlistat is a medication that works by inhibiting the absorption of dietary fat in the intestines. It prevents the breakdown of fat molecules, leading to reduced calorie absorption and weight loss. Orlistat is available in prescription-strength (Xenical) and over-the-counter (Alli) formulations. Common side effects include gastrointestinal symptoms such as oily stool, flatulence, and abdominal discomfort. - Phentermine (Adipex-P, Lomaira):
Phentermine is a stimulant medication that suppresses appetite and reduces food intake by affecting certain neurotransmitters in the brain. It is typically prescribed for short-term use as an adjunct to diet and exercise in the treatment of obesity. Phentermine is available in various formulations and dosages. Common side effects may include increased heart rate, elevated blood pressure, insomnia, and dry mouth. - Lorcaserin (Belviq):
Lorcaserin is a serotonin receptor agonist that works by promoting feelings of fullness and reducing appetite. It is prescribed for weight management in adults with obesity or overweight who have at least one weight-related comorbidity. Lorcaserin is taken orally and may be associated with side effects such as headache, dizziness, nausea, and fatigue. - Naltrexone-Bupropion (Contrave):
Contrave is a combination medication that contains naltrexone, an opioid antagonist, and bupropion, an antidepressant and smoking cessation aid. It works by suppressing appetite and reducing food cravings. Contrave is approved for long-term weight management in adults with obesity or overweight who have at least one weight-related comorbidity. Side effects may include nausea, constipation, headache, and insomnia. - Liraglutide (Saxenda):
Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that regulates appetite and promotes weight loss by slowing gastric emptying and reducing food intake. It is administered as a daily injection and is approved for long-term weight management in adults with obesity or overweight who have at least one weight-related comorbidity. Common side effects include nausea, vomiting, diarrhea, and constipation. - Topiramate-Phentermine (Qsymia):
Qsymia is a combination medication that contains phentermine, a stimulant appetite suppressant, and topiramate, an anticonvulsant medication. It works by reducing appetite and increasing feelings of fullness. Qsymia is approved for long-term weight management in adults with obesity or overweight who have at least one weight-related comorbidity. Side effects may include tingling sensations, dizziness, altered taste sensation, and insomnia.
It’s important to discuss the potential benefits and risks of weight loss medications with a healthcare provider before starting treatment. These medications may not be suitable for everyone and may interact with other medications or medical conditions. Healthcare providers will carefully evaluate individual factors and preferences to determine the most appropriate treatment options for each individual. Additionally, weight loss medications should be used as part of a comprehensive weight management plan that includes dietary changes, increased physical activity, and behavioral interventions.
What are the types of weight loss surgery?
Weight loss surgery, also known as bariatric surgery, encompasses several surgical procedures designed to promote weight loss and improve obesity-related health conditions. These procedures are typically recommended for individuals with severe obesity or obesity-related health complications who have not achieved adequate weight loss with nonsurgical interventions. Here are the main types of weight loss surgery:
- Gastric Bypass Surgery (Roux-en-Y Gastric Bypass):
Gastric bypass surgery is one of the most common and effective weight loss procedures. During this surgery, the surgeon creates a small pouch at the top of the stomach and connects it directly to the small intestine, bypassing a portion of the stomach and the upper part of the small intestine. This reduces the amount of food the stomach can hold and alters the absorption of nutrients. Gastric bypass surgery results in significant weight loss and improvement in obesity-related health conditions such as type 2 diabetes and hypertension. - Sleeve Gastrectomy (Gastric Sleeve Surgery):
Sleeve gastrectomy involves the removal of a large portion of the stomach, leaving behind a narrow tube or sleeve-shaped stomach. This reduces the stomach’s capacity to hold food and decreases appetite by affecting hunger hormones. Sleeve gastrectomy is a less complex procedure than gastric bypass and is associated with significant weight loss and improvement in obesity-related comorbidities. - Adjustable Gastric Banding (Lap-Band Surgery):
Adjustable gastric banding involves placing an inflatable silicone band around the upper part of the stomach, creating a small pouch that limits the amount of food the stomach can hold. The band can be adjusted by adding or removing saline solution through a port placed under the skin. Adjustable gastric banding is reversible and requires regular adjustments to optimize weight loss. While it is less invasive than other procedures, it may result in slower weight loss and a higher risk of complications such as band slippage or erosion. - Biliopancreatic Diversion with Duodenal Switch (BPD/DS):
Biliopancreatic diversion with duodenal switch is a complex weight loss procedure that involves two surgical steps. The first step is similar to a sleeve gastrectomy, where a portion of the stomach is removed to create a smaller stomach pouch. In the second step, a significant portion of the small intestine is bypassed, redirecting food from the stomach directly to the lower part of the small intestine. This reduces calorie absorption and results in significant weight loss. BPD/DS is typically recommended for individuals with severe obesity or obesity-related health conditions. - Bariatric Revision Surgery:
Bariatric revision surgery may be necessary for individuals who have experienced inadequate weight loss or complications following a previous weight loss procedure. Revision surgery may involve converting one type of bariatric surgery to another, repairing or revising a previous procedure, or addressing complications such as gastric band slippage or pouch dilation.
Each type of weight loss surgery has its own benefits, risks, and considerations. The choice of procedure depends on factors such as the individual’s weight, health status, medical history, and personal preferences. Healthcare providers will carefully evaluate each patient to determine the most appropriate surgical option for achieving optimal weight loss and improving overall health outcomes. Additionally, bariatric surgery is typically accompanied by comprehensive preoperative evaluations, postoperative care, and ongoing support to ensure long-term success and minimize complications.

The prevention of obesity requires a multifaceted approach that addresses individual behaviors, societal influences, and environmental factors. Here are the key takeaways for preventing obesity:
- Healthy Eating Habits: Emphasize a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit processed foods, sugary snacks, and high-calorie beverages, and practice portion control to avoid overeating.
- Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity per week. Incorporate a variety of physical activities into daily routines to promote movement and reduce sedentary behaviors.
- Supportive Environments: Create environments that facilitate healthy eating and active living at home, school, work, and community settings. Advocate for policies and initiatives that increase access to nutritious foods, safe recreational spaces, and opportunities for physical activity.
- Education and Empowerment: Provide education and resources on nutrition, physical activity, portion control, and healthy lifestyle habits. Empower individuals and families with the knowledge and skills to make informed choices about food, exercise, and overall health.
- Address Socioeconomic Disparities: Address socioeconomic factors that contribute to disparities in obesity rates, such as income inequality, food insecurity, and limited access to healthcare resources. Support initiatives to improve access to affordable, nutritious foods, and healthcare services in underserved communities.
- Promote Mental and Emotional Well-being: Address psychological and emotional factors that influence eating behaviors, such as stress, depression, anxiety, and emotional eating. Encourage healthy coping mechanisms and provide access to mental health services and support networks.
By implementing these strategies and promoting a culture of health and wellness, we can work towards preventing obesity and improving overall health outcomes for individuals, families, and communities.
