Gastric Bypass in India

What is Gastric Bypass ?

Gastric bypass surgery is one of several weight-loss surgeries currently performed. The operation itself has undergone several modifications over the years. The procedure in use today is called the Roux-en-Y gastric bypass. It shouldn't be confused with other weight-loss surgeries, such as the biliopancreatic diversion with duodenal switch, which is a more aggressive surgery.

Your doctor or a registered dietitian will talk with you about the diet you'll need to follow after surgery, explaining what types of food and how much you can eat at each meal. Closely following your gastric bypass diet can help you lose weight safely.

Purpose

The gastric bypass diet has several purposes:

To allow your stomach to heal without being stretched by the food you eat.

To get you used to eating the smaller amounts of food that your smaller stomach can comfortably and safely digest.

To help you lose weight and avoid gaining weight.

To avoid side effects and complications from the surgery.

Diet details

Diet recommendations after gastric bypass surgery vary depending on where the surgery is performed and your individual situation.

A gastric bypass diet typically follows a staged approach to help you ease back into eating solid foods as you recover. How quickly you move from one step to the next depends on how fast your body heals and adjusts to the change in eating patterns. You can usually start eating regular foods about three months after surgery.

Liquids

For the first day or so after surgery, you'll only be allowed to drink clear liquids. Sip slowly and drink only 2 to 3 ounces (59 to 89 milliliters) at a time. Once you're handling clear liquids, you can start having other liquids, such as skim or low-fat milk.

Pureed foods

Once you're able to tolerate liquids for a few days, you can begin to eat strained and pureed (mashed up) foods. During this phase, you can only eat foods that have the consistency of a smooth paste or a thick liquid, without any solid pieces of food in the mixture.

Solid foods

After about eight weeks on the gastric bypass diet, you can gradually return to eating firmer foods. But foods must still be chopped or diced. Start slowly with regular foods to see what foods you can tolerate. You may find that you still have difficulty eating spicier foods or foods with crunchy textures.

Gastric Bypass Diet

Throughout The Diet

To ensure that you get enough vitamins and minerals and keep your weight-loss goals on track, at each stage of the gastric bypass diet, you should:

Eat and drink slowly. Eating or drinking too quickly may cause dumping syndrome — when foods and liquids enter your small intestine rapidly and in larger amounts than normal, causing nausea, vomiting, dizziness, sweating and eventually diarrhea. To prevent dumping syndrome, choose foods and liquids low in fat and sugar, eat and drink slowly, and wait 30 to 45 minutes before or after each meal to drink liquids. Take at least 30 minutes to eat your meals and 30 to 60 minutes to drink 1 cup (237 milliliters) of liquid.

Keep meals small. During the diet progression, you should eat several small meals a day and sip liquids slowly throughout the day (not with meals). You might first start with six small meals a day, then move to four meals and finally, when following a regular diet, decrease to three meals a day. Each meal should include about a half-cup to a cup of food. Make sure you eat only the recommended amounts and stop eating before you feel full.

Drink liquids between meals. Expect to drink at least 6 to 8 cups (48 to 64 ounces, or 1.4 to 1.9 liters) of fluids a day to prevent dehydration. Drinking liquids with your meals can cause pain, nausea and vomiting as well as dumping syndrome. Also, drinking too much liquid at or around mealtime can leave you feeling overly full and prevent you from eating enough nutrient-rich food.
