Gastric Bypass Before and After

How will you prepare for a Gastric Bypass surgery?

Medical Exam: First, the surgeon examines the patient to determine whether he/she is a candidate for a Gastric Bypass Surgery. This preoperative examination includes lab tests, among others.

All health problems should be reported to the surgeon. It is of great importance that illnesses such as hypertension, diabetes, and other health issues are well controlled before the surgery is performed. Possible or actual pregnancies must be reported as well. The patient needs to inform the surgeon of all medications (including over-the-counter medications, vitamins, herbs, etc) he/she is taking. The patient will then be informed which medications should be discontinued before the surgery, as well as when they should be discontinued.

Nutritional counseling: Our dietitian will counsel our patients on healthy nutrition habits before and after the surgery. Having good nutrition habits not only supports weight loss but also helps to maintain ideal body weight.

Emotional support: Our psychologists will determine the emotional status of the patients and help them to prepare emotionally for the surgery and the time thereafter.

The night before the surgery: The patient will be asked not to eat or drink anything for 12 hours immediately before the surgery.

What to expect after a Gastric Bypass surgery:

Gastric Bypass patients will stay in the hospital for 2-3 days. On the first day of the surgery the patient will be asked to sit in a chair for a while and to walk short distances. Remember that mobilization helps to prevent blood clots from forming. (see Gastric Bypass complications for more information )

For a few days the patient will have a nasogastric tube (tube inserted through the nose to the stomach) which drains the pouch (the newly created stomach) from any fluids. Another tube may be placed in the bypassed part of the stomach to drain fluids. After a couple of days the patient should be able to tolerate clear liquids and pureed foods and will then be discharged from the hospital.

Expected weight loss after surgery: The more the patient adheres to the proper diet (Read Gastric Bypass Diet for more information ) the more weight he/she will lose. Within 2 years, one half or more of the extra weight will be lost.

Other benefits: Gastric Bypass surgery helps the patient to lose weight, and as a result, other illnesses, such as type 2 diabetes, hypertension, sleep apnea, and gastroesophageal reflux disease (GERD) will be much improved.
