Life After Bariatric & Weight Loss Surgery

The Post-Op Diet

Your special diet actually starts before surgery with 10 days of a high protein liquid diet. After surgery, the diet progresses from liquids to regular food slowly over 6 weeks.

Lap Band Adjustments

Gastric lap bands may require adjustment (fills with saline through the port) in order to be fully effective. Post operatively, lap band patients are seen in the clinic monthly until adequate restriction is achieved.

Vitamin and Mineral Supplementation

  • All post-op patients are prescribed nutritional supplements because intake of food is restricted and patient may become vitamin or mineral deficient.
  • Because their surgeries also affect malabsorption of nutrients, bypass and sleeve patients receive multivitamins, iron, and calcium with Vitamin D, Vitamin B12, and a B Complex.
  • Lap band patients take a multivitamin and calcium with Vitamin D. Lab tests are performed periodically to assure good nutrient status.
  • Duodenal Switch patients have the added requirement of high dose Vitamins A, D, E and K.

Bariatric Surgery Support Groups

Research has shown that support group attendance is crucial to continued weight maintenance after bariatric surgery.

Fletcher Allen Health Care offers a monthly support group at the Blair Park Road Clinic in Williston on the first Monday of every month. The support group meets from 6 - 7 p.m.

All pre-operative and post-operative patients and their families are encouraged to attend the support groups. In addition, several "satellite" support groups comprised of former patients have started in the outlying areas. Contact us for further details.
