Obesity can lead to many harmful diseases such as diabetes, sleep apnea, arthritis, high blood pressure and stroke. Hence, it is of prime importance to be healthy and to have the appropriate body weight. In many cases, people cannot reduce their weight by dieting and exercise. Therefore, Bariatric Surgery is performed in order to limit the amount of food intake of the patient. Bariatric Surgery has proved to be beneficial in long-term weight loss, and decreased susceptibility to diabetes and reduction in cardiac diseases.
There are several risks involved in a Bariatric Surgery. There are chances of pouch stretching in which the stomach may dilate over time and restore its original size which would again increase the weight of the patient. There are also possibilities of breakdown of staple lines as well as stomal stenosis in which a constriction is formed between the stomach and the small intestine causing digestive disorders. Due to the decreased pathway of absorption of food after the surgery, deficiencies in vitamins and minerals may occur. Bariatric Surgery may also result in dumping syndrome in which the food passes through the pathway too quickly. It also leads to higher risk of osteoporosis, diarrhea and malnutrition due to less absorption of nutrients.
It is essential to be on a liquid diet for at least 2 days after surgery. Only soft foods such as porridge, surd, egg whites etc. can be eaten then for about a month. The patient is recommended to walk regularly after the surgery and proper physical exercise should commence only after 3 months of surgery. The patient must take vitamin and mineral supplements to avoid deficiency diseases.
