Gastric bypass surgery may help lower death rates associated with type 2 diabetes, heart disease, and cancer. Cons: heartburn, abdominal pain, and vomiting. Increased risk of nutritional deficiencies, dumping syndrome, and other complications from surgery. Death rate within one year of surgery is 1-5.
Answer to Question 2
Some scientist believe that the number and size of adipocytes may influence the ability to maintain a healthy weight. People with fewer, enlarged adipocytes may have less difficulty maintaining weight loss than those with a greater number of smaller adipocytes. Avoiding excessive weight gain can help minimize one's adipocyte population, since in adults new adipocytes are not formed until existing ones are full of stored lipids. Once the number of adipocytes has increased, it usually remains higher than before despite any subsequent weight loss.
