How to Prevent Vomiting After Gastric Sleeve Surgery?


Nausea and vomiting are potential aftereffects of gastric surgery. There are some meals and drinks that can bring on nausea. A momentary change in the flavor and aroma of foods may cause you to feel queasy, and throwing up after gastric sleeve is common, but try to have an open mind.

Before beginning to eat healthy meals again, it is vital to give the body time to readjust to digest good foods. Give it another go after a week or two has passed if the initial attempt wasn’t successful.

Intolerances of foods like red meat, untoasted bread, pasta, and lactose are common. Meats often taste metallic, and sweet foods and drinks take on an unpleasant aftertaste. After an operation, some patients even report that water has a delicious taste.

Nutritionally, it will be crucial to replenish lost fluids and electrolytes with plenty of water and sugar-free electrolyte drinks at this time. Now is the right time to consider the causes of this adverse impact and the steps patients can take to lessen their experiences of nausea after gastric sleeve surgery.

The Syndrome Of Dumping


The dumping syndrome might strike five to 10 minutes after you finish eating. Constipation, stomach pain, and nausea are early symptoms of dumping syndrome. You could get hot, disoriented, weak, and even faint. The rate of your heartbeat may increase, and you may start to sweat heavily.

Diarrhea is a common symptom of dumping syndrome, but not always. The symptoms of dumping syndrome that manifest 1 to 3 hours following the initial episode are strikingly similar to those of hypoglycemia. You might get weak, dizzy, and queasy.

You can avoid dumping syndrome by limiting your intake of simple sugars and fats at any meal; taking time while eating will also help. An individual’s tolerance for simple sugar and fat will undoubtedly vary. This is why paying attention to your diet’s calorie, and nutrient content is essential. Most people can eat safely at or below 5 grams of total sugar per serving.

How Quickly You Eat

The average surgeon advises patients to take 30–60 minutes to consume each meal. Using baby hardware for meals is an excellent method to put this into practice. It will serve as a visual signal to remind people to take their time when eating. The risk of vomiting increases when food is consumed too soon.

Chewing The Food

Always take the time to completely chew your food before swallowing. In this way, the brain can better determine when the stomach is full, reducing the risk of bloating and overeating. Generally, you can easily digest meals with a smoothie or pudding consistency.

Consuming An Excessive Amount Of Food

Several people who have had weight loss surgery (WLS) reported feeling sick after overeating for days after their procedure. You can use 4-ounce Tupperware to control portion sizes when prepping meals. You will have to modify the kinds and quantities of food you eat. Seeing a doctor can help you learn more about your body and how it works.

Developing Food Intolerance

Digestion changes and adapts at varying speeds for each patient. You should keep track of the foods that fit you because they may not suit other people. Remember that many intolerances are just transitory, so it may be possible to successfully reintroduce the food after trying it in smaller amounts.

Getting Into Bed Too Soon After Eating


A person should wait at least two hours after eating before going to sleep. The risk of developing symptoms, including heartburn, nausea, and vomiting, increases when you lie down too rapidly.

Skipping Further In The Process

After gastric sleeve, many patients experience nausea and vomiting because they attempt to eat solid food too quickly. People ingesting solid food too soon after surgery might cause nausea and vomiting due to the stomach’s inability to digest the meal properly.

After surgery, most patients are given a food plan to follow by their dietician and doctor. The improved meal quality will keep patients satisfied for longer. Patients are instructed to begin the diet plan by drinking only liquids, progressing to smoothies and other soft foods, and finally to more solid fare.

Getting And Retaining Fluids

Patients should drink 8 cups of water daily to prevent dehydration, but doing so too soon after eating can trigger nausea and vomiting. Waiting 30 minutes to an hour is the standard recommendation made by doctors and dietitians before eating any fluid.

Since your stomach size has been drastically reduced, you cannot immediately return to your previous drinking habits; instead, you should take things slowly and methodically while your body adjusts to its new stomach.

Vitamin Supplementation In The Absence Of Food


Many people get sick after taking vitamins on an empty stomach. Instead, you could try taking your vitamins with food to avoid feeling sick. A person needing advice or assistance is encouraged to consult their physicians and dietitians.

Most patients have little trouble swallowing chewable vitamins, but some must use liquid supplements instead.


The stomach-to-small intestine stoma will heal after weight loss surgery. However, the new connection between the stomach and the small intestine that the surgery forged carries the risk of scar tissue formation.

Stomach Ulcers

One risk of gastric sleeve surgery is the development of ulcers, which can worsen postoperative nausea and vomiting. If you smoke, your risk of developing an ulcer is significantly higher than average. If you can, refrain from lighting up anymore.


After an operation, it’s not uncommon for patients to feel queasy. This is because some unpleasant side effects are inevitable as your body attempts to change into a better version of itself.


You might need to make an appointment with your primary care physician at home to obtain a prescription for anti-nausea medicine. That depends on whether or not you’re currently sick with nausea and vomiting. If throwing up after the gastric sleeve persists, ensure that you closely check on this. Get in touch with a doctor there if you feel a need.

After having gastric sleeve surgery, we hope that the following advice and suggestions may help you have less nausea and vomiting. Don’t forget that these are only some suggestions and that if you feel any slight pain or signals that are not typical, you should contact your doctor as soon as possible.
