What make someone obese? What causes Obesity? – Dr Vikram Lotwala
In this video, Dr. Vikram Lotwala, bariatric and laparoscopic surgeon at Wings Hospital, Surat, explains what causes obesity, and why it is a medical condition rather than simply a lack of willpower.
What causes obesity?
Obesity develops when, over a long period, the body takes in more energy than it uses. But many factors influence that balance, and most are not fully in a person's control:
- Genetics and family history: genes affect appetite, fullness and how the body stores fat.
- Diet: high-calorie, processed and sugary foods and drinks, large portions and irregular meals.
- Physical inactivity: desk jobs, long commutes and screen time reduce daily energy use.
- Sleep and stress: poor sleep and chronic stress disturb the hormones that control hunger.
- Medical conditions: hypothyroidism, PCOS and some hormonal disorders can contribute to weight gain.
- Medicines: some steroids, antidepressants and diabetes medicines can cause weight gain.
- Environment and habits: easy access to calorie-dense food and lifestyle changes over time.
Why obesity is hard to reverse
When someone loses weight through dieting, the body often responds by increasing hunger and slowing metabolism. This is why lost weight frequently returns, and why obesity is now recognised as a chronic disease that may need medical treatment.
When to seek medical help
If diet and exercise have not worked, or if your weight is linked to diabetes, high blood pressure, sleep apnoea or joint pain, speak to a specialist. Depending on your BMI and health, options include lifestyle programmes, weight-loss medication, the intragastric balloon or bariatric surgery.

There is rarely one cause. Obesity usually results from a mix of genetics, diet, inactivity, sleep, stress, medical conditions and medicines.
Is obesity a disease?
Yes. Major medical organisations recognise obesity as a chronic disease that affects hormones, metabolism and overall health.
When should I consider bariatric surgery?
Usually when BMI is 35 or above, or 30 and above with conditions like diabetes. Lower thresholds apply to Asian patients. A specialist will advise.
