What Is Obesity? Understanding the Condition

Obesity is a medical condition defined by excess body fat that negatively affects health and daily functioning. Clinicians typically use body mass index (BMI) as an initial screening tool: a BMI of 30 or higher indicates obesity. For Asian population the definition of obesity is with lower BMI because of the increased risk factors. But BMI is only part of the picture- body fat distribution, metabolic health, and related medical problems also matter. At GEM Hospital and Research Centre, our multidisciplinary team evaluates each patient’s overall health, lifestyle, and long-term goals before recommending a personalized treatment plan. We focus on safe, evidence-based obesity treatment options – Life style modifications, Medications and laparoscopic bariatric surgery for eligible candidates.

Common Causes and Risk Factors of Obesity

Obesity results from a combination of environmental, genetic, and behavioural factors rather than a single cause. Common contributors include:

• Caloric imbalance: consuming more calories than are burned through daily activity and metabolism.
• Sedentary lifestyle: Reduced physical activity results in fewer calories being burned.
• Genetic predisposition: family history can influence appetite regulation and fat storage.
• Medical conditions and medications: hypothyroidism, polycystic ovary syndrome, and certain drugs can promote weight gain.
• Psychological factors: stress, depression, and emotional eating can significantly influence eating habits.
• Socioeconomic and cultural influences: limited access to healthy food options, high-calorie eating habits, and busy schedules contribute to a higher risk.

At GEM hospital and Research Centre in Thrissur, we screen patients for medical and lifestyle contributors to obesity so treatment addresses root causes, not just symptoms.

Health Complications Linked to Obesity

Uncontrolled obesity raises the risk of multiple chronic conditions that reduce quality of life and longevity. These include:

• Type 2 diabetes and insulin resistance
• Hypertension and cardiovascular disease
• Sleep apnea and respiratory problems
• Joint degeneration and osteoarthritis
• Certain cancers (including colorectal and breast cancer)
• Fatty liver disease and reduced fertility
• Mental well-being issues, including anxiety and depression

Reducing weight through effective obesity treatment lowers these risks and can reverse or improve many obesity-related illnesses. GEM Hospital’s integrated care model ensures both surgical and non-surgical pathways are coordinated with specialists in endocrinology, cardiology, pulmonology, and mental health.

Effective Treatment Options for Obesity Management

Treatment begins with a full assessment and shared decision-making between the patient and our clinical team. Options include:

• Medical and behavioural therapy: supervised diet plans, physical activity programs, and behavioural counselling form the foundation of weight management. Prescription medications may be appropriate for some patients to support weight loss.
• Endoscopic and minimally invasive procedures: for select patients, endoscopic interventions can aid weight loss with shorter recovery compared with traditional surgery.
• Laparoscopic bariatric surgery: when conservative measures fail or when obesity is severe, bariatric surgery may be the most effective long-term treatment. GEM Hospital and Research Centre specializes in advanced laparoscopic techniques such as sleeve gastrectomy and gastric bypass. These procedures reduce stomach size and/or alter digestive pathways to promote early satiety, reduced calorie absorption, and hormonal changes that favour weight loss.

Patients receive preoperative optimization, then Bariatric surgery from experienced laparoscopy surgeons, and structured postoperative support including nutrition counselling and follow-up to maintain results.

Lifestyle Changes for Long-Term Weight Control

Sustainable weight management relies on lifelong lifestyle changes supported by education and ongoing care. Key elements include:

• Balanced, nutrient-dense diet: focus on vegetables, lean proteins, whole grains, and controlled portion sizes.
• Regular physical activity: combine aerobic exercise with strength training to preserve muscle and improve metabolism.
• Behavioural strategies: setting realistic goals, tracking progress, managing stress, and addressing emotional eating habits.
• Sleep and stress management: adequate sleep and techniques like mindfulness reduce hormonal drivers of weight gain.
• Medical follow-up: regular checkups with physicians, dietitians, and physical therapists to track progress and modify the plan.

Patients who undergo obesity surgery at GEM Hospital and Research Centre receive a structured rehabilitation and education program to help translate surgical success into sustained health improvements.
