You will need to follow strict eating instructions provided by your health-care team after weight-loss surgery. In the early weeks, it may be difficult to eat anything without feeling uncomfortably full, and your stomach may still be very tender. Depending on the type of surgery, you may be on a liquid diet for several weeks. Gradually, you will work up to eating soft, easily chewable foods and then progress to frequent, small meals (about two ounces each). The actual number of meals may vary from four to six a day. Not only do you need to adjust to eating more frequently and consuming smaller amounts of food, but you will also need to eat slowly and chew your food thoroughly. Initially, you won't be able to drink fluid with meals because it can cause discomfort. Instead, you'll drink fluids 1/2 to 1 hour after meals. You will receive lists of suggested foods to eat and foods to avoid. In general, you will need to eat foods higher in protein and low in fat.

Depending on the type of surgery you have, you may need to take a multivitamin with iron every day and a calcium supplement. You may also need intramuscular shots of vitamin B12.

Weight-loss surgery may be an option to consider if you need more help than diet and exercise can provide. Bariatric surgery is a drastic measure. Learn as much as you can and speak with your doctor to make the best decision.
