Obesity is a chronic medical condition defined by an excess of body fat that impairs health. It is not simply a lifestyle choice or a matter of willpower but it is a complex, multifactorial disease driven by genetic, hormonal, environmental and behavioural factors. In India, obesity is classified using modified BMI (body mass index) thresholds: a BMI of 23 to 27.5 kg/m² is considered overweight and above 27.5 kg/m² is obese for Asian populations.
Left unmanaged, it drives type 2 diabetes, hypertension, heart disease, sleep apnoea, and cancer. At Ramkrishna CARE Hospitals Raipur, obesity is treated as a serious chronic disease with management ranging from lifestyle interventions to bariatric surgery.
Types of Obesity
Obesity is classified by BMI severity and fat distribution pattern.
- Class I obesity: BMI 27.5 to 32.5 kg/m²; increased risk of metabolic complications begins at this level
- Class II obesity: BMI 32.5 to 37.5 kg/m² and has a high complication risk so bariatric surgery is considered when comorbidities are present
- Class III obesity (severe or morbid obesity): BMI above 37.5 kg/m² and has a very high complication risk; the threshold above which bariatric surgery is recommended regardless of comorbidities
- Central (abdominal) obesity: Excess fat concentrated around the abdomen (waist circumference above 90 cm in men and above 80 cm in women by Asian criteria). It is more metabolically harmful than generalised fat distribution and strongly associated with insulin resistance, cardiovascular disease, and fatty liver disease
- Secondary obesity: Develops from hypothyroidism, Cushing's syndrome, PCOS, or medications and must be excluded before treatment begins.
Signs and Symptoms of Obesity
Direct and secondary symptoms from associated conditions:
- Breathlessness on exertion or lying flat
- Joint pain in the lower back, knees and hips
- Fatigue, excessive sweating, and reduced exercise tolerance
- Skin changes like skin fold rashes (intertrigo) and dark patches indicating insulin resistance (acanthosis nigricans)
- Symptoms of comorbidities like chest pain, excessive thirst and morning headache
- Depression, anxiety and poor self-esteem.
Causes of Obesity
Obesity occurs when energy intake exceeds expenditure driven by multiple, interlocking factors:
- Diet and inactivity: Ultra-processed foods, large portions, sedentary work and screen-based leisure are the primary modifiable factors
- Genetics: Heritability plays a big role; genes influence appetite, fat storage and metabolic rate
- Hormones and metabolism: Insulin resistance, leptin resistance (leptin signals fullness) and hypothyroidism all promote fat accumulation
- Medications: Certain medicines like corticosteroids, antipsychotics, and antidepressants promote weight gain
- Sleep: Sleep deprivation raises ghrelin (the hunger hormone) and lowers leptin.
- Psychological and socioeconomic factors: Stress, depression, emotional eating, food insecurity and limited access to healthy food all increase risk.
Obesity Diagnosis
Diagnosis combines objective measurements with risk assessment. They are:
- BMI calculation: BMI is the primary screening tool and is also used in classifying obesity based on weight and height
- Waist circumference: Above 80 cm in women and above 90 cm in men indicates central obesity with elevated cardiometabolic risk
- Body fat percentage: Measured by BIA or DEXA scan. It is more precise than BMI, distinguishing fat from muscle mass
- Blood tests: Measure fasting glucose, HbA1c, lipid profile, liver and thyroid function, and kidney function
- Blood pressure: Cardiovascular risk assessment
- Polysomnography (sleep study): When obstructive sleep apnoea is suspected
- Abdominal ultrasound: Identify NAFLD (fatty liver disease) and gallstones (both of which you can commonly see associated with obesity).
Risk of Obesity
Risk escalates with higher BMI and central fat:
- Metabolic syndrome: Central obesity with hypertension, high triglycerides & insulin resistance increases the risk of cardiovascular disease and type 2 diabetes by a lot
- Age: The risk of obesity increases with age due to slower metabolism, decreased muscle mass and lower physical activity levels
- Family history: Individuals with a family history of obesity are more prone to develop the condition.
- Duration of excess weight: The longer a person remains overweight, the greater the risk of developing further weight gain.
- Ethnicity: Indian patients are at high metabolic risk even at BMIs of 27 to 30.
Complications of Obesity
Obesity does not affect just one part of the body. It places sustained pressure on nearly every organ system and significantly raises the risk of conditions that are often chronic, progressive and difficult to manage in isolation. Key complications are:
- Type 2 diabetes
- Hypertension and cardiovascular disease
- Sleep apnoea
- Obstructive sleep apnoea and other breathing disorders
- Fatty liver disease and liver damage
- Osteoarthritis and joint problems
- Gastroesophageal reflux disease (GERD)
- Infertility and pregnancy-related complications
- Polycystic ovary syndrome (PCOS)
- Chronic kidney disease
- Reduced mobility and physical functioning
- Malignancy like colon, breast, endometrial, kidney, and pancreatic cancers are more common in obesity.
Obesity Treatment Options
Treatment is matched to severity and patient goals.
- Lifestyle Modification: The foundation for all patients. A calorie-controlled diet, 150 minutes of moderate exercise weekly, behavioural therapy, and sleep hygiene produce 5 to 10% body weight loss that is enough to reduce diabetes risk and blood pressure.
- Pharmacological Treatment: Weight-loss medications are indicated for patients with a BMI above 27.5 kg/m² with comorbidities, or above 30 kg/m² without comorbidities, when lifestyle modification alone is insufficient. Currently available agents include:
- Lipase inhibitor (reduces fat absorption)
- GLP-1 receptor agonists.
- Bariatric (Weight Loss) Surgery: The most effective long term treatment for severe obesity, producing 20 to 40% body weight loss and resolving type 2 diabetes in the majority of patients. Three procedures are offered at Ramkrishna CARE Hospitals, Raipur:
- Sleeve gastrectomy: In this surgery a large portion of the stomach is removed that leaves behind a smaller, sleeve-shaped stomach. This limits how much food a person can eat at one time and reduces hunger by lowering the production of appetite-regulating hormones. It is the most commonly performed bariatric procedure today.
- Gastric bypass (Laparoscopic Roux-en-Y Gastric Bypass): A small pouch is created from the upper stomach & connected directly to the small intestine (bypassing a section of the digestive tract) which helps you in restricting food intake and reducing calorie absorption and produces metabolic benefits.
- Adjustable gastric band: A silicone band is placed around the upper portion of the stomach, creating a smaller pouch that helps patients feel full after smaller meals. This band can be loosened, tightened or removed depending on how the patient responds. This procedure is performed less frequently now, largely because of higher rates of revision surgery compared to other options.
What is the Procedure of Obesity Treatment?
The bariatric surgery process at Ramkrishna CARE Hospitals, Raipur is structured, multidisciplinary and patient-centred. Steps are:
- Multidisciplinary assessment: A multidisciplinary assessment including surgical, medical, dietary and psychological reviews is conducted for bariatric surgery. Doctors perform blood tests to exclude endocrine causes.
- Preoperative workup: Doctors perform blood tests, an ECG, an upper GI endoscopy and a sleep study if apnoea is suspected. A pre-operative low calorie diet for two to four weeks reduces liver size and operative risk.
- Bariatric surgery: Robotic-assisted or laparoscopic surgery under general anaesthesia through four to five small incisions; 60 to 120 minutes.
- Hospital stay: Hospital stay 2 to 3 days. Diet progresses from liquids to normal food over 6 to 8 weeks.
- Follow-up and aftercare: Appointments at 1, 3, 6 and 12 months. Lifelong vitamin supplementation (B12, iron, calcium, vitamin D). Doctors adjust medications as weight loss progresses.
