Nutritional needs for the person who has undergone gastric bypass surgery are of great importance. The amount of food your new stomach can handle at one time is greatly reduced. Therefore, it is extremely important to get the nutrients and vitamins you need every day for the rest of your life.

Typical Blended Diet Immediately After Surgery

•   

Liquids sipped throughout the day, between meals only, and at a controlled rate (20-30 minutes for every 6 ounces)

Food is cut into very small pieces (thumbnail size), liquid is added, and all is blended to a smooth consistency with no lumps, pieces, or seeds

Jars of commercial baby food may also be used

Hot spices are to be avoided

Each meal should be eaten over a 30 minutes to one hour period since your new stomach can only hold about 2 ounces

Eat 6 times per day

2 children's sugar-free vitamins/minerals with iron every day

Starting About One Month After Surgery

•   

Protein protein protein. Always gets your protein in first (milk, yogurt, chicken, fish, eggs, protein shakes)

Start experimenting with solids foods in very small quantities to see what your new stomach will tolerate

You must avoid foods with sugar. There is a possibility of "dumping" when sugary foods are eaten. Dumping is often caused by food emptying too fast into your intestine, and concentrated foods such as sugar will cause water to enter the intestines which can result in diarrhea, sweating or clammy skin, light-headedness, and nausea. Drinking immediately after a meal can also cause dumping.

Switch from children's vitamins to adult vitamin/mineral supplements. A separate Vitamin B12 supplement (500mcg) may be required also if your blood work indicates low iron levels
