The closest thing to a cure is the substantial reduction in weight that we at our best obesity centre in Hyderabad achieve following bariatric surgery. Even in these patients who have undergone bariatric surgery weight regain could happen after many years following surgery. The main reason for obesity being curable is the fact that obesity is the result of multiple genetic abnormalities which are accumulated in a single person. It could also be due to some changes at the genetic level which happen in Utero during fetal life or due to environmental exposure in infancy. Due to these reasons, the cure of obesity is extremely difficult and has been frustrating.
BMI or body mass index is the ratio of your weight in kilograms divided by your height in meters square. Generally BMI is considered as a measure of the amount of body fat that is stored in your body, which is more true above a BMI of 27 or 28 kg/m². Normal BMI is considered between 18.5 to 25 kg/m². Even in this BMI, some people do have excess body fat which is stored around the waist. This is central obesity and can have adverse consequences in the form of high BP, diabetes, mellitus, and excess cardiovascular risk.
Obesity at its core is a genetic disease. Instead of a single gene encoding for a protein being responsible, obesity is due to multiple genes being abnormal and being present in the same individual. Twin studies have shown that BMI is similar even if the environment is very dissimilar.
Apart from genes other influences that can contribute to obesity include:
Obesity is classified based on the distribution of body fat into two broad categories:
Obesity is graded based on its severity as measured by body mass index. The following classes of obesity are broadly recognised as:
Obesity is not uniformly symptomatic in most patients who are obese. It does produce symptoms in a significant minority. At our best obesity centre in Hyderabad, the symptoms are identified first to determine whether it is obesity or some other condition. Symptoms will include fullness or bloating, poor physical capacity, breathlessness on exertion and fatigue etc. Excess daytime sleepiness can be a symptom of obesity if it causes OSA or obstructive sleep apnoea. Above a BMI of 35 kg/m² a good number of patients will have lower limb edema. Obesity can cause type2 diabetes and hypertension and these conditions can lead to symptoms. For example if someone with obesity gets diabetes, they can have sudden weight loss if the blood glucose is very high. They can develop tingling, burning or numbness in feet if there is neuropathy. Hypertension can cause heaviness in the head or buzzing in the head. If you have a BMI above 30 and if you have any of the above symptoms, it is important that you meet a doctor to verify whether the symptoms are due to any complications of obesity or due to obesity itself.
