Your New Diet After Bariatric Surgery
If you have questions about any of the information below, please contact the bariatric surgery team in Seattle at (206) 341-0060 or Federal Way at (253) 874-1604, option 3.
After discharge from the hospital you will continue a strict liquid diet for two weeks.
Not everyone advances at the same rate. Your progress depends on how well you tolerate the diet and how well you follow the guidelines.
Your new stomach can hold only two ounces, or one-fourth cup, at a time; therefore, small amounts of liquid are used.
After two to three weeks, if you are doing well without problems, such as frequent nausea or vomiting, your diet will be changed to a pureed diet. This diet, followed for about two to four weeks, includes soft applesauce-consistency foods, in addition to the liquids already allowed.
Usually about four to six weeks after surgery, you will begin the gastric bypass soft diet, which introduces solid foods for the first time since your operation. Your new stomach still can hold only two to three ounces at a time. The amounts of food and liquids included continue to be small.
Not everyone progresses at the same rate. Your progress depends on how well you tolerated the pureed diet.
As mentioned earlier, if you eat a balanced diet and take your vitamin and iron supplements, it is unlikely that you will develop any known nutritional deficiencies after surgery.
Unless you are having trouble, we will ask you to try all foods. Occasionally, certain foods cause diarrhea. In some patients, certain foods cause nausea or prolonged fullness.
Our hope is that eventually you will be able to eat any kind of food you wish, although in small quantities. Many patients, however, find that they avoid certain foods for the reasons above.
For example, some patients have trouble eating red meat, such as steak, or pork.
After discharge from the hospital, you will follow a liquid diet for one week, then advance to pureed or applesauce-consistency foods for the second week, and finally onto soft-textured foods the third week. By the fourth week, you will be eating a regular-texture, healthy, balanced diet including: fruit, vegetables, whole grains, beans, eggs, fish, meat, poultry and dairy products.
The idea behind this diet progression is to have you eating small portions of regular foods by the time your Lap-Band is tightened/adjusted for the first time, four weeks after it was first placed.
Like people who have had gastric bypass surgery, people who have had Lap-Band surgery will benefit from eating small portions (about one-half cup or four ounces) of healthy food, five to six times per day. This eating style provides energy and nutrition throughout the day.
After surgery, it is recommended that you take a chewable or liquid multivitamin/mineral supplement every day, along with calcium containing vitamin D.
