Obesity and Metabolic Syndrome

Obesity and metabolic syndrome become a medical problem, rather than a question of appearance, when excess visceral fat starts to drive diabetes, high blood pressure, abnormal blood fats, sleep apnoea and joint disease. Dr. Rakesh Durkhure, Head - General, MI & Bariatric Surgery (Unit IV), Artemis Hospitals, Gurugram, India, urges doctors to look for it behind the complaints patients actually bring: snoring, breathlessness, backache, painful knees, infertility and uncontrolled sugar.

His Jivo Masterclass for international doctors covered the full arc of the condition: how to recognise it, who genuinely needs treatment, what the medical and surgical options achieve, and how a referral should be prepared. This guide sets out the diagnostic and referral framework. Two companion articles go deeper: balloon vs sleeve vs gastric bypass, with the selection criteria and safety record, and bariatric surgery for type 2 diabetes, with the outcome data and the cost case against lifelong medication.

What metabolic syndrome is: the five components

Metabolic syndrome is a cluster of linked abnormalities that together raise the risk of type 2 diabetes, heart disease and stroke. Dr. Durkhure's slide places visceral obesity, the fat packed around the abdominal organs, at the top of the cluster.

The standard definition counts five components:

• Central (visceral) obesity, measured by waist circumference, with thresholds that vary by sex and ethnic group.
• Raised blood glucose, the visible sign of insulin resistance (the body's reduced response to its own insulin), ranging from impaired fasting glucose to frank type 2 diabetes.
• Raised blood pressure, at or above 130/85 mmHg, or treated hypertension.
• Raised triglycerides, at or above 150 mg/dL (1.7 mmol/L).
• Low HDL cholesterol, the "good" cholesterol, below 40 mg/dL (1.0 mmol/L) in men or 50 mg/dL (1.3 mmol/L) in women.

A patient with any three of the five meets the internationally harmonised definition. The practical point for a referring doctor is that the components travel together. A patient who arrives with one of them, typically diabetes or hypertension, should be checked for the others, and the waistline is usually the first clue.

Warning signs of obesity and metabolic syndrome in everyday practice

The warning signs of obesity and metabolic syndrome usually arrive as a complaint in another specialty, not as "obesity". That is Dr. Durkhure's central diagnostic message. He grouped the signals into five clusters that should prompt a doctor to consider the diagnosis.

Breathing and sleep

The first cluster is respiratory. A patient who is overweight, breathless and has swelling of the legs (oedema), or who has sleep apnoea, should be assessed for obesity-driven disease. Obstructive sleep apnoea is the repeated collapse of the upper airway during sleep, which fragments rest and starves the body of oxygen overnight. It is one of the conditions most reliably improved by weight loss, a point the outcome data in the diabetes and outcomes article makes strongly.

Sugar, cholesterol, liver and heart

The second cluster is metabolic. Diabetes, raised cholesterol, liver disease and cardiac disease in an overweight patient point towards metabolic syndrome rather than a set of unrelated diagnoses.

The psychological burden

Dr. Durkhure gave the psychological dimension equal weight. He described patients living with obesity as often having low self-esteem and low confidence, avoiding going out in public because of social discrimination, and living with a constant, depression-like low mood. This matters clinically: it affects whether a patient seeks help at all, and it is one reason his programme includes a psychologist (described in the surgery options article).

Spine, joints and the abdominal wall

The fourth cluster is mechanical. Constant backache, hernias of the abdominal wall, and osteoarthritis of the hip or knee joints caused by excess weight should all prompt a doctor to consider that the patient has metabolic syndrome.

Gynaecology and continence

The fifth cluster belongs to obstetrics and gynaecology. Dr. Durkhure listed infertility, uterine myomas (fibroids) and abnormal uterine bleeding as problems linked to excess weight. He noted that myomas are very common among African women, and that he has seen overweight women experience intermittent urinary leakage as they approach older age.

What are the earliest signs of obesity?

The earliest signs of obesity are a tightening belt, a partner's report of snoring and breathlessness on modest exertion. Asked in the live session, Dr. Durkhure gave these three signs that any patient can notice at home:

1. The belt tightens. A waist belt that starts to feel tight is the very earliest sign.
2. A partner reports snoring. A husband or wife saying the patient snores too much in bed is an early marker of airway compromise.
3. Breathlessness on modest exertion. Feeling very breathless after running 100 metres or so is a warning sign.

Each maps onto one of the clusters above: central fat, sleep-disordered breathing and reduced cardiorespiratory reserve. The full exchange appears in the Live Discussion from this masterclass.

Why weight loss advice so often fails

Popular weight loss approaches often fail because they aim at the wrong fat. Dr. Durkhure was blunt: "You cannot burn fat from outside," he told the audience; body fat has to be burnt from inside. The target is visceral fat, the fat that drives metabolic disease.

He identified a second, structural problem: many patients want to stop overeating but do not know when or where to seek help, or what the right advice is. Part of the explanation is biological rather than behavioural: the stomach itself produces a hormone that pushes the brain to eat more. That mechanism, and why operations that change the gut's hormonal signals work, is explained in the diabetes article.

Who should be treated for obesity?

Two groups should be treated for obesity: people who are obese and unhappy with it, and people whose obesity has already produced disease. Not every person with obesity should be pushed towards weight loss treatment. Dr. Durkhure's first selection principle is the patient's own view. "Not all obese should go for weight loss," his slide read. A person who is obese and unhappy with it is a good candidate. A person who weighs 100, 120 or 130 kg and is content should not be pressed into surgery.

The exception is disease. A patient who is content with their weight but carries comorbidities (coexisting diseases) such as diabetes, hypertension, breathlessness or sleep apnoea is, in his assessment, a good candidate for weight loss surgery, because the weight is now harming them whether or not it troubles them.

That principle is then formalised into hard criteria (body mass index, age, motivation, psychological fitness and absence of active cancer), which are set out with the international guideline context in the surgery options article.

Obesity treatment options at a glance

The main treatment options for obesity are an intragastric balloon, sleeve gastrectomy, gastric bypass and the newer GLP-1 medicines, drugs that mimic a gut hormone controlling appetite and blood sugar. Dr. Durkhure presented all four; the figures below are those he gave in the session.

His conclusion was that surgery is permanent and leaves patients happier, while medicines work only for as long as they are taken. The detailed comparison of the three operations sits in the surgery options article; the diabetes results, the outcome data and the cost comparison sit in the type 2 diabetes article. For the procedure itself, see the bariatric surgery cost page.

Obesity treatment is a team effort

Obesity treatment works best as a programme, not a single operation. Dr. Durkhure stressed that the operation is one part of a programme run with an endocrinologist, a chest physician, a dietitian, a physiotherapist and a psychologist. "It is a joint effort," he said; the team and its safety record are described in the surgery options article.

How to refer a patient for bariatric surgery

To refer a patient for bariatric surgery, share the investigations and symptoms with the surgical team first, then arrange an online consultation. The masterclass set out a practical pathway built on trust between the local doctor and the surgeon.

• Share investigations first. Dr. Durkhure asked that a patient's investigations and symptoms be shared before an online outpatient consultation, so the team can decide which patients need a consultation, or ask the local doctor for a couple of further tests and then review the results together.
• Counsel with evidence. Asked how doctors in Africa can counsel patients who hold firm beliefs about surgery or fear relapse, he pointed to the results of patients he has already operated on, who have come from Kenya, Nigeria, Mozambique, Ghana, Chad, Rwanda, Burundi and Congo. Those success stories, followed by online consultations to answer the patient's questions, are his recommended route.
• Continuity after surgery. He records a video of each operation and gives it to the patient, so the patient can show it to the referring doctor or any gastrointestinal surgeon at home.

Beyond bariatric surgery: what else can be referred

Beyond bariatric surgery, the same service treats hernias, gallbladder, colorectal and anal conditions. Dr. Durkhure closed by widening the scope. His service also treats:

• Hiatus hernia, in which part of the stomach moves from the abdomen into the chest, often presenting as indigestion and hyperacidity.
• Complicated gallbladder stones, particularly where a stone has slipped into the bile duct; routine gallstones, he noted, can be managed at the local centre. See the gallbladder removal cost page.
• Diseases of the colon and small intestine.
• Complex abdominal hernias, including inguinal and umbilical hernias and recurrent hernias that have come back after a local repair. See the hernia repair cost page.
• Rectal prolapse, complex piles (haemorrhoids) and fistulas near the back passage; a fistula is an abnormal tunnel between the bowel and the skin. See the fistula surgery cost page.

All of these, he said, can be managed and the patient sent back with a satisfactory outcome. Robotic approaches to several of these operations are covered in his separate masterclass: see the complete guide to robotic and laparoscopic surgery. His full profile is on the Dr. Rakesh Durkhure doctor page, and the specialty overview is on the general and bariatric surgery hub.
