What's the treatment of obesity?The mainstay of treatment for obesity is an energy-limited diet and increased exercise. Although adherence to this regimen can cure obesity, a large segment of patients is unable to make the required sacrifices. There might be an additional
behavioral factor at the brain level "forbidding" obesity patients from losing too much weight.
Much research focusses on new drugs to combat obesity, which is seen as the biggest health problem facing developed countries. Some nutritionists feel that these these research funds would be better devoted to advice on good nutrition, healthy eating and promoting a more active lifestyle. Medication prescribed for diet/exercise-resistant obesity is orlistat (Xenical®, reduced intestinal fat absorption by inhibiting pancreatic lipase) and sibutramine (Reductil®, Medaria®, an anorectic).
In the presence of diabetes mellitus, there is evidence that the anti-diabetic drug metformin (Glucophage®) can assist in weight loss - rather than sulfonylurea derivatives and insulin, which often lead to further weight gain. The thiazolidinediones (rosiglitazone or pioglitazone) can cause slight weight gain, but decrease the "pathologic" form of abdominal fat, and are therefore often used in obese diabetics. Increasingly, surgery is being used to limit stomach capacity (and thus food intake); this can happen laparoscopically. Ileal bypass reduces the length of the intestine and hence absorbing surface, but has more complications.
A weight loss of 5 or 10kg among obese patients has a very positive effect on the risk of heart and blood-vessel diseases. The weight loss will not only reduce blood pressure and blood-cholesterol, but also have a beneficial impact on obesity-related diseases. The help of a dietitian can result in weight-loss of 5 to 10kg in more than 90 per cent of patients put on regular diets of, for instance, 1500 to 2000 kilocalories per day, based on calorie-counting. Another option to attain the same result involves changing to an unlimited consumption of low-fat foods. After losing weight, thorough guidance on shopping and preparation of foods with a fat-energy-percentage of 20 to 25 per cent is of paramount importance, in order to stop the weight being put back on. Furthermore, it is important to increase daily physical activity. Patients, who do not reach a satisfactory weight-loss on a diet, may be subjected to medical or surgical treatment.
