Foods You Shouldn’t Eat After Bariatric Surgery


The purpose of bariatric surgery is to decrease the size of your stomach so that you will be satisfied eating smaller portions, which means that your diet is going to have to change significantly in order to ensure proper nutrition. Your doctor will most likely advise you on your diet, but there will still be questions about what you should and should not eat.

Whether you get surgery in Mexico, the United States, or any other appropriate location, you’ll still be dealing with the same sort of recovery. In order that make that recovery goes as smoothly as possible, you’ll need to carefully follow the instructions from the doctor while also avoiding entire groups of foods that no longer have value. Below is a list of food types that should be avoided after receiving a gastric sleeve.

Vegetables High in Fiber

After you’ve received a gastric sleeve, it will initially be difficult to digest vegetables that have a lot of fiber. Examples of veggies with high fiber include celery, broccoli, corn, and asparagus. These foods will become easier to digest as you recover from the surgery, but softer vegetables should be the focus immediately after the procedure. Carrots or peas are both excellent options.

Carbohydrates High in Starch

Anything that is high in starch becomes a thick, hard-to-swallow paste after it has been chewed. Bariatric surgery patients often have a hard time swallowing thicker foods shortly after the procedure, and most doctors recommend that such patients avoid drinking any fluids with meals. In rare cases, it is possible for high-starch carbohydrates to block the entrance to the stomach, which leads to vomiting and nausea. While these foods can technically be eaten in moderation, it is best to avoid them.


Making the transition to an appropriate diet after surgery in Mexico or any other location can be difficult, but it is not impossible. Alcohol should certainly be avoided. Most alcohols are fairly high in calories, and they offer no nutritional value. They also take up a lot of space in your newly-confined stomach. Some studies have even shown that such procedures can reduce alcohol tolerance in the patient. Focus on consuming foods that are high in vitamins and minerals instead.

Empty Calories

These are calories that offer no value to your nutrition, meaning they merely provide calories but nothing else. Most foods that contain empty calories fall in the category of ‘snack’ or ‘junk’ food, including chips, candy, pastries, pretzels, crackers, popcorn, sodas, and sugary juices. These foods can quickly fill the stomach of a bariatric patient, but they can lead to undernourishment if they make up the bulk of your diet. This basically means that you’ll feel as if you are eating enough, but you won’t be getting the required nutrition to make your body function as it should.

Foods High in Fat

High-fat foods might be tasty, but they are generally meant to be avoided, regardless of whether or not you’ve recently experienced bariatric surgery. These foods have the potential to cause a condition known as dumping syndrome, which occurs when recently eaten food is dumped directly into the colon without being properly digested by the stomach. If this were to happen, you would experience nausea, cold sweat, and potential vomiting. Fried foods should especially be avoided, as well as sausage, bacon, and milk.
