Preparing for Gastric Bypass Surgery

Dr. Jacqueline Osuna, serving Guadalajara and Tijuana, MX, can help you in preparing for gastric bypass surgery. Your diet and level of physical activity before gastric bypass surgery will have a significant influence on your recovery and long-term results. It is also imperative to make scheduling arrangements that will allow you to rest and adjust after surgery.

Three Months before Your Procedure

In the months before surgery, it is advised that patients make many of the dietary and lifestyle changes that are required after surgery. This will help make the transition easier, rather than trying to make many changes all at once following an operation. This will also prepare your body for the significant physical changes that accompany gastric bypass surgery. Some of the steps patients are asked to take include:

Eating a Healthy Diet

After surgery, your body will not be able to process as much food as before due to your decreased stomach capacity. Eating a healthy diet becomes all the more important to ensure that you consume the nutrients you need. The wrong dietary choices can cause gastric bypass patients to easily experience malnutrition and uncomfortable side effects such as dumping syndrome.

balanced meal

A carefully balanced preparatory diet can ease your transition into life after bariatric surgery.

Eating Protein

Protein is critical to weight loss because it helps you to feel fuller sooner and for a longer period of time. Consuming high - but not excessive - quantities of protein can also help prevent loss of muscle mass, a common side effect of rapid weight loss.

Chewing Slowly

Eating slowly and chewing mindfully helps prevent overeating and stretching your stapled stomach. Making a habit of pacing your meal intake before surgery can be tremendously beneficial when you begin life after gastric bypass surgery.

Taking Supplements

Since gastric bypass surgery alters the digestive tract and inhibits nutrient absorption, patients will need to take supplements following their procedure. It is a good idea to incorporate this into your daily routine prior to surgery to make it a habit.


Patients should slowly begin exercising regularly by doing an activity they enjoy. Ideally, patients will work themselves up to moving for about 20 to 30 minutes each day.

Patients are also encouraged to quit smoking, reduce caffeine intake, and abstain from alcohol.

Two Weeks Before Surgery

Two weeks before surgery, patients should begin a diet consisting exclusively of liquids such as protein shakes. Tomato juice and very thin cream of wheat may also be acceptable, depending on your doctor's advice. At this point, patients are usually advised to adopt a conservative caloric intake of between 800 and 1,200 calories per day.

One week prior to surgery, patients should stop taking aspirin and other blood thinners.

By this time, patients should have arranged their time off from work, transportation to and from their home, child care, and at-home help. This is also the time to prepare your home by stocking up on the right food and dietary supplements. Medical tourism involves special travel considerations, and we are prepared to help you make these arrangements.
