“I’ve tried everything — diets, gym memberships, early morning walks. Nothing works.”

This is a sentence doctors hear almost every day. It reflects not failure, but deep frustration. On the occasion of World Obesity Day, it is important to recognise that obesity is not merely a lifestyle issue – it is a chronic, progressive disease that often requires structured medical care.
A 54-year-old woman recently walked into our clinic weighing 109.5 kilograms, with a body mass index (BMI) of 50.7 – categorising her condition as severe obesity. For years, she had been battling uncontrolled diabetes and hypertension. Despite taking four oral anti-diabetic medications and a staggering 115 units of insulin daily, her blood sugar levels remained poorly controlled, with an HbA1c of 11.8%.
Further medical evaluation revealed additional complications, including severe fatty liver disease, gallstones and symptoms strongly suggestive of obstructive sleep apnea – a condition often linked with obesity and associated with increased cardiovascular risk.
After careful medical evaluation and preparation, she underwent Roux-en-Y gastric bypass surgery along with laparoscopic gallbladder removal. The procedure was performed using minimally invasive techniques, allowing for faster recovery and reduced surgical trauma. Within two days of surgery, her medications were reassessed and significantly reduced, and she was safely discharged on the third postoperative day.
The results over the next six months were remarkable. She lost 25 kilograms, and her insulin requirement dropped dramatically from 115 units per day to just 16 units, along with only one oral diabetes medication. Her HbA1c improved from 11.8% to 7%, indicating much better diabetes control. Her liver enzymes normalised, reflecting recovery from fatty liver disease, while her blood pressure medications were reduced and cholesterol medication was discontinued.
Commenting on the case, Dr. Saravana Kumar, Lead Consultant – Department of Obesity & Diabetes Surgery Centre, GEM Hospital, Coimbatore, says, “World Obesity Day reminds us that obesity is not simply about weight — it is a complex metabolic disease. Patients often struggle for years with diets and medications before seeking medical help. Metabolic surgery offers a scientifically proven option for individuals with severe obesity and uncontrolled diabetes. In many cases, it not only helps patients lose weight but also significantly improves or even reverses diabetes and other metabolic conditions, helping them regain health and quality of life.”
This case highlights the powerful role of bariatric surgery, not merely as a weight-loss intervention but as a treatment for metabolic disorders. For many patients struggling with severe obesity and uncontrolled diabetes, timely medical intervention can reduce medication dependence and dramatically improve overall wellbeing.
