Hi & Welcome. Thanks for the query. I can understand your problem and feel that you are really very interested in reducing your body weight. Chechwt (Cetilistat) tablet is a commonly used anti obesity drug for the long term weight management. Along with necessary dietary changes and regular exercise it is found to be effective in reducing the increased body weight. Since it blocks the absorption of fat from the gut by inhibiting the digestion of dietary fat, it is known to cause side effects like abdominal pain, bloating, flatulence, oily stools, and deficiencies of fat soluble vitamins on long term use. The draw back of this medicine is that it does not suit everybody and the problem with this medicine is that the moment this medicine is stopped, rebound weight gain occurs unless and until necessary diet changes, regular exercises and lifestyle changes are also incorporated in the medication schedule. Hope I could answer your query. Wishing you best of your health.
