Obesity is a complex medical condition characterized by excessive accumulation of body fat, which poses a significant risk to health. It is typically determined by body mass index (BMI), a measure calculated by dividing a person's weight in kilograms by the square of their height in meters. A BMI of 30 or higher is generally considered indicative of obesity.
Obesity results from a combination of genetic, environmental, behavioral, and hormonal factors, as well as socio-economic influences. Dr. Pushpender Khatana specializes in identifying the root causes of obesity and developing personalized, effective management plans.
Unhealthy Diet: Diets high in calories, saturated fats, sugars, and processed foods can contribute significantly to weight gain and obesity. Factors like lack of access to nutritious foods or resources for healthy eating can also play a role.
Lack of Physical Activity: Sedentary lifestyles, characterized by low levels of physical activity, are strongly associated with obesity. Regular exercise is crucial for burning calories and maintaining a healthy weight.
Genetics: Genetic factors can predispose individuals to obesity by influencing metabolism, appetite regulation, and fat storage. However, genetics alone do not determine whether someone will become obese; environmental and lifestyle factors also play a significant role.
Medical Conditions: Certain medical conditions and medications can contribute to weight gain and obesity. These include conditions like hypothyroidism (underactive thyroid), polycystic ovary syndrome (PCOS), Cushing's syndrome, and the use of some psychiatric medications or corticosteroids.
Psychological Factors: Emotional eating, chronic stress, depression, anxiety, and past trauma can all contribute to overeating and subsequent weight gain.
Socio-Economic Factors: Socio-economic status can impact access to healthy foods, opportunities for physical activity, and resources for effective weight management interventions.
Obesity significantly increases the risk of developing a wide range of serious health problems and chronic diseases, including Type 2 Diabetes, heart disease, stroke, certain types of cancer (e.g., colon, breast, endometrial, kidney), osteoarthritis, sleep apnea, and mental health disorders such as depression and anxiety.
Preventing and managing obesity requires a comprehensive and individualized approach that addresses both personal and, where relevant, societal factors. Dr. Pushpender Khatana focuses on promoting sustainable healthy eating habits and regular physical activity, providing guidance on accessing nutritious foods, and offering resources for effective weight management. Treatment strategies for obesity may include personalized dietary plans, structured exercise programs, behavioral therapy, medication, and in some cases, referral for bariatric surgery when appropriate. Successful long-term weight management often requires sustained lifestyle changes and ongoing medical and psychological support.
