Maintaining Your Gastric Bypass Diet is Key to Your Recovery

After gastric bypass surgery, patients will need to follow a strict diet while their new stomach adjusts, beginning with clear liquids. This diet is designed to help patients achieve better weight loss results and reduce their risk for digestive issues or other surgical complications. It can also motivate patients to eat healthier as part of their new lifestyle. During your pre-surgical appointments at our Tijuana, Mexico, practice, Dr. Jacqueline Osuna can review your gastric bypass diet, which will cover what to eat both before and after surgery. She can review post-surgical care to help you achieve the smoothest possible recovery.

You may reintroduce solid foods into your diet at week six.

The Importance of a Healthy Diet

image of healthy dietThe gastric bypass diet is designed to help you obtain the most successful results after surgery and throughout your recovery. By altering your diet beforehand, you can help your body adjust to consuming and properly digesting smaller amounts of food. If you return to eating larger quantities of food after surgery, your stomach may stretch, and you may experience more serious digestive issues.

What to Eat Before Surgery

During the weeks leading up to surgery, you will be required to follow a strict, liquids-only diet, including:

  • Protein shakes
  • Vegetable juices
  • Sugar-free beverages
  • Beef, chicken, or vegetable broth
  • Soups
  • Creamy, hot breakfast cereals, such as cream of wheat

It is imperative that you avoid carbonated and caffeinated beverages, as well as fruit juices during this time. You should also consume water separately from your meals. Failing to follow this diet could lead to your procedure being postponed.

Your Post-Op Diet

Week 1: Clear Liquids

For the first week following surgery, you can consume only clear liquids. This consists of:

  • Water
  • Broth
  • Skim or one percent milk
  • Thin, creamy soups (with no protein bits or vegetable chunks)
  • Unsweetened fruit or vegetable juice
  • Decaffeinated tea or coffee
  • Gelatin
  • Sugar-free popsicles

Dr. Osuna can provide you with a more comprehensive list should you have additional questions.

Weeks 2 to 3: Adding Pureed Foods

Once your body is able to tolerate clear liquids without complications, you can begin adding pureed foods and meal replacement shakes, such as:

  • Smoothies
  • Protein shakes
  • Egg whites
  • Mashed beef, chicken, or fish
  • Cottage cheese
  • Pureed fruits and vegetables

Much like your pre-op diet, it is important that you consume water and any other liquids 30 minutes before and 30 minutes after eating, but not while you eat. You should still avoid caffeinated and carbonated beverages at this point. Because your digestive tract will be sensitive, we recommend limiting spicy and dairy-based foods. Although it is easier to consume these foods with a straw, you should sip them from a cup. Drinking through a straw can lead to unwanted air in your stomach and cause digestive cramping.

Weeks 4 to 5: Soft Foods

Around the four-week mark, you can begin to eat soft foods. Your diet can include:

  • Finely diced, lean proteins
  • Egg whites
  • Cottage cheese
  • Steamed vegetables (green beans, carrots, potatoes, squash)
  • Avocados
  • Bananas
  • Fresh fruits (without seeds or skin)

During this time, you should consume protein and certain vegetables that are easily mashed, while limiting starches and hard-to-digest foods.

Your Ongoing Diet

Over the course of the next few weeks, you may gradually reintroduce solid foods back into your diet. Remember, the healthier, the better. Because this procedure is both restrictive and malabsorptive in nature, the foods you eat need to be nutritious. Reverting to former eating habits can cause your stomach to stretch and lead to dumping syndrome, a severe digestive disorder associated with nausea, vomiting, diarrhea, fatigue, cramping, and increased heart rate. You should generally avoid consuming:

  • Grains and bread
  • Fried, processed foods
  • Fatty proteins
  • Carbonated beverages
  • Sugary foods

It is also to important to approach foods like nuts, whole grains, and corn cautiously, as they are harder to digest. Remember to eat small portions, chew your food slowly and carefully, and avoid drinking liquids during mealtimes. You may find that eating six small meals is better suited to your new way of life.
