Depending on your tolerance, this phase can last from 1 to 2 weeks. These food options are also appropriate for a gastric bypass food list.

Your doctor or dietitian will provide you with a recommended number of calories. Caloric intake can range at this phase and the goal will be to try and reach daily protein goals and maintain hydration. If you have concerns with what you are able to consume, consult with your bariatric healthcare team immediately.

Tips For Eating After a Gastric Sleeve

  • Cut your food into very small pieces. Don’t be concerned about the small portion sizes. You should typically be eating 4-5 times daily.
  • Remember to eat slowly. Take at least 30 minutes to eat a meal. Chew every bite to a paste consistency before swallowing.

  • Watch out for empty calories. This includes foods and beverages with no nutritional value and high in calories like pretzels, chips, and pastries. Getting to know food labels will help.
  • Consume protein-rich foods first. Make lean, high quality protein the core of your diet.
  • Carbohydrates should not be excluded. However, you should be choosing healthy sources of carbohydrates, such as cooked vegetables, whole grains and fruits.
  • Avoid foods that can cause inflammation while the stomach is healing. Stick to the food options on your gastric sleeve food list.
  • Introduce one food at a time. Some new foods may not be tolerated well. However, try different foods again when you are further out from surgery.
  • Do not consume fluids with meals. Wait 30 minutes before eating and 30 minutes after to drink a beverage.
  • When directed to do so, stay consistent with your bariatric supplement regimen.

Week 3: Meal Preparation

Measure Every Portion

You will find measuring utensils very handy. At this phase, you will likely be using measuring spoons and measuring cups to portion out meals. During week 3 after bariatric surgery, start with 1/8 to 1/4 cup portions for meals. It is important to take into account that the stomach is 75% smaller and healing.

Soften and Puree Meals

It’s a good idea to peel all your fruit and vegetables before cooking and mashing. Don’t eat fibrous veggies like celery unless they are well cooked and liquidized.

Steam or slow-cook food to soften it, especially fish, meat, and vegetables. When in doubt, put foods through a blender or food processor.

Foods that are not tolerated well may cause vomiting, acid reflux, diarrhea, or constipation. Having pureed diet recipes can be helpful in still making eating fun during this phase.

Use Bariatric-Friendly Tools and Recipes

Find dinnerware that helps you eat slowly and dish up small portions, such as specifically designed portion control bowls and plates. Use small cutlery and a timer to allow slower eating.

If you find that you are getting bored and running out of ideas, find a gastric sleeve cookbook. These options can have high-protein recipes adapted to your particular needs and can be used throughout your entire weight loss journey.

Taking Care of Yourself 3 Weeks After Gastric Sleeve Surgery

Establish Good Habits as Soon as Possible

As you are still recovering, learn to plan meals and start your lifestyle change. This will be difficult, but bariatric surgery is only a tool for weight loss. You will be required to utilize your bariatric resources to promote good habits in the future and maintain consistency throughout your bariatric journey. This will result in the most weight loss benefits from surgery.

Some things to start with would be to avoid carbonation, caffeine, and alcohol until further direction is provided by a healthcare professional. Starting with a small step like this can help to manage weight loss and overall health.

Daily Fluids

Hydration is important. Make sure you are choosing the right beverages after surgery. Your body requires fluids to function properly. After surgery, the difficulty of staying hydrated increases as you won't be able to take much in.

Avoid alcohol until permitted. Alcohol can trigger cravings. It can also cause stomach irritation, swelling and vomiting. Alcohol can be high in sugar and calories while also lacking nutrition. Many cocktails are mixed with carbonated beverages high in sugar that are also not recommended.

Carbonated drinks cause bloating and gas after surgery. Not only can this cause stomach issues, they are typically high in sugar. Carbonated beverages and alcohol can also promote acid reflux after gastric sleeve surgery.

Caffeine can be a natural diuretic when frequently consumed. The idea is to reach a goal of 64 oz of fluids daily. It will be hard enough to stay hydrated after surgery, so stick with non-caffeinated beverages initially. Staying hydrated will require very small sips throughout the day. Water will always be your best option.

Unexpected Symptoms

Your doctor may advise you of symptoms to look for after surgery, like mild pain and tenderness. Symptoms should be monitored and ease up by week 3. If you are still having considerable pain, contact your bariatric provider.

If you are having serious pain, adverse side effects, or bleeding, get medical attention as soon as possible.

Don't Skip Meals

You may notice that your appetite is poor. Don’t skip meals in your diet plan, even though they seem small. This can have considerable effects on your blood sugar levels. Also, nutrients from food provide you with the energy your body needs. Skipping meals may also effect recovery time.

You can avoid low blood sugar after gastric sleeve surgery by eating regularly. Keep eating each small meal in your diet plan.

Taking Supplements and Medication

There is a very high risk of nutrient deficiency after gastric sleeve surgery. Bariatric specific supplements will be required for life to prevent deficiencies and compensate for the vitamins and minerals you are no longer getting through food sources.

It is typically recommended to take chewable supplements initially after bariatric surgery. This will promote absorption and allow the stomach to heal.

Healthy eating and exercise will be the key to successful weight management in the long-term. Reach out for help to healthcare professionals when you are struggling.

Any prescribed medications should still be taken as directed by your bariatric healthcare team. You can also discuss what pain medication is allowed after gastric bypass and gastric sleeve surgery.
