After care following gastric bypass

Medications on discharge

Antacid therapy for 3 months to reduce ulceration at the joinup between the pouch and the bowel (gastrojejunostomy) Analgesia (pain relief), generally panadol elixir and other medications as required on discharge.

Postoperative diet following gastric bypass

In the early post operative phase, days 1-42, there will be swelling around the staple lines which will slowly settle as healing occurs. It is most important to carefully follow your post operative diet to maximize your chance of a good result. Clear fluids for 7 days following surgery - Pureed foods until 6 weeks following surgery - Solids after this. It is critical that any food is chewed extremely well following this. Some foods such as white bread and lumps of meat may not be tolerated as it forms dough balls and can stick at the anastomosis. They therefore should be avoided.

Our dietitian will work with you preoperatively and postoperatively. In general you will eat tiny amounts, a tablespoon or so at a time. It is important to stop eating as soon as you feel full to avoid stretching the pouch. Once you are on solids, do not drink with your food. Drink water between meals, this provides the necessary intake and will help suppress hunger. Do not snack. Minimise alcohol intake.

Nutritional Requirements following gastric bypass

All patients will need to take Multivitamins. These can be bought from the chemist. We do not generally start these until one month after surgery. They can be crushed or swallowed whole. Vitamin B12, folate and iron levels need to be monitored and supplemented by your family doctor as required. Occasionally iron injections are necessary. Calcium supplementation is advisable in women particularly around the menopause.

Post-op diet following adjustable band

Pureed/soft diet for 6 weeks to allow band to bed into surrounding tissues prior to adjustments being made.

Nutritional requirements following adjustable band

Multivitamins during periods of weight loss - generally not required long term.

Band adjustment

Will begin at 6 weeks after surgery on a 4-6 weekly basis as required.

Reduction in comorbidities and medication requirements following weight reduction surgery

There is an 80% chance of in curing maturity onset (Type II) diabetes with gastric bypass. Most patients will be able to get off all diabetic medication or have a substantial reduction in medication requirements. Antihypertensive medication is often substantially reduced as is the need for antigout medication and antinflammatories. Breathing difficulties including sleep apnoea and snoring are generally resolved or substantially improved. Exercise tolerance is improved and bothersome symptoms such as reflux and joint pain will frequently resolve. Patients are more likely to exercise and develop more confidence as they see the results of surgery.
