Obesity & Metabolic Disorders

Obesity is the storage of body fat to a degree that affects health. It is measured by body mass index and by waist circumference together, and the waist matters because fat carried around the abdomen and inside the organs behaves very differently from fat under the skin of the hips and thighs.

Indians develop the metabolic consequences at a lower body weight and a smaller waist than European populations, so the thresholds used here are lower. Someone whose weight looks unremarkable can already have insulin resistance, a fatty liver and an abnormal lipid profile.

Body weight is defended by biology. Appetite and energy use are controlled by hormones from the gut, the fat tissue and the brain, and after weight is lost those signals push to regain it, and maintaining a loss takes as much support as achieving it. Sleep, medication, thyroid and hormonal conditions, and long-term stress all move the same dials.

Your doctor measures weight, height and waist, and takes your blood pressure with a cuff of the right size, since a small cuff gives a falsely high reading on a large arm.

They then work in two directions. They look for causes: an underactive thyroid, hormonal conditions, untreated sleep apnoea, and the medicines that drive weight gain, including several used for diabetes, mood and epilepsy. And they look for consequences already present, examining the liver, the skin folds for the velvety darkening that signals insulin resistance, and the joints.

They will ask about your weight through your life, what has worked before and for how long, your eating pattern through the day, your sleep, your snoring, your mood and your cycles. Blood tests usually cover sugar and the three-month average, lipids, thyroid function, liver function and vitamin D. This history takes time, and a first appointment is longer than most.

This is a long-term condition managed over years instead of an episode with an end.

A supervised programme is judged at three to six months, and the target early on is five to ten per cent of body weight, because that is the amount that measurably lowers blood sugar, blood pressure, liver fat and the strain on joints, well before any change in appearance. Medical treatment is reviewed at similar intervals and continued while it works.

Where an operation is chosen, expect two to three days in hospital, two to four weeks off work depending on your job, a staged return to normal food over six to eight weeks, and lifelong supplements and follow-up. Weight falls over twelve to eighteen months afterwards.

Regain is common in every route and it reflects the body defending its previous weight. Continuing contact with your team, instead of discharge once the weight is down, is what holds the result.
