What Causes Constant Vomiting After Gastric Sleeve Surgery?

You could have nausea and vomiting following gastric sleeve surgery for several reasons. You should know that changing diet and digestion patterns may produce nausea and vomiting during the initial adjustment phase. Were you aware that leaving puking untreated can result in long-term issues? So, we’ll examine the reasons for constant vomiting after gastric sleeve surgery and suggest prevention.

Eating Too Quickly

We are accustomed to moving quickly through life. One of those things is eating. It is important to remind patients to chew their food thoroughly on a regular basis. This is especially true in the initial months following the operation. Your stomach’s ability to hold food is drastically reduced after bariatric surgery. Eating too quickly prevents the smaller stomach from clearing the food adequately. You’ll end up throwing since the food won’t digest.

It’s crucial to take your time while eating. Take into account avoiding interruptions while eating. When multitasking, it’s common to forget to slow down, which leads to eating too quickly and subsequent problems. It would help if you got into the habit of only eating, especially at first. No talking, TV viewing, or Facebooking is allowed while dining. Just take your time, settle down, and eat.

Eating Excessively

We were trained to overeat since we were young children. It would help if you finished everything because people are starving to death.

You must abandon that way of thinking following weight loss surgery. Your new stomach can’t expand to hold more food since it is less elastic than your old one. Stopping to eat is necessary once you are satisfied. Otherwise, you’ll throw up.

You’ll need to become familiar with your body’s new cues to let you know when you’re full. Some people report upper abdominal pain. Some people will experience hiccups or a feeling that their meal is in their throat. Discover how to read your new stomach and STOP when you are full.

Remember that you should only eat when you are hungry and quit when you are full. After all, preventing you from overeating is one of the main goals of bariatric surgery.

Eating The Wrong Foods

You will need to adhere to a diet after weight loss surgery. Liquids are the first thing on a diet, then pureed food, a soft diet, and finally, conventional food. The procedure takes about 6 to 8 weeks. Even though we repeatedly advise our patients to follow this process, occasionally, a patient will decide to skip a step and begin eating solid food much too soon.

After bariatric surgery, eating chicken when you should be on a liquid diet will undoubtedly result in vomiting. A patient recently complained that he kept puking up a hamburger, which disturbed him. Yes, including bread. You should be following a puree diet, sir.

Do yourself a favor and adhere to the diet guidelines. It is present for a purpose.

Improper Chewing

You can now eat regular food, and you should no longer be in danger. Well, not quite yet. The initial three months following weight loss surgery need significant adjustment. You’ll have to relearn how to eat and how quickly. With time, it will become more straightforward, but in the beginning, you must take time and digest each word.

It would help if you thoroughly chewed any hard veggies you enjoy eating, such as broccoli or carrots. Otherwise, you won’t be pleased when they become trapped in the smaller gut. Certain types of meat may cause similar problems for other patients. After weight loss surgery, eating steak, white chicken meat, and pork is known to create vomiting problems.

So constantly chew your meal thoroughly. Learn what and how much you can consume by eating slowly. Additionally, just because you currently accept a food group does not guarantee that you always will. Give it some time, then give it another go in a few weeks or months.

Surgical Concerns

After bariatric surgery, prolonged vomiting is typically brought on by this. Patients may vomit due to surgical problems immediately following surgery or years later.

Vomiting following bariatric surgery is typically not regular. You should consult a bariatric surgeon if you are experiencing problems. Ulcers, intestinal obstruction, sleeve narrowing, hernias, and many more conditions can all result in vomiting.

The kind of surgery required depends on the problem. For instance, the small stomach and small bowel become connected following a gastric bypass. The connection may narrow if there is excessive healing or scar tissue. This region will make it hard for the food to pass through, and eventually, vomiting will occur to clear the stomach of leftover food.

After a sleeve, you might experience some sleeve twisting, resulting in gastric emptying problems. These are mechanical problems that are frequently fixable. That is why I advise you to get medical help if you often vomit after having bariatric surgery. You might also need to get a second opinion. Only some bariatric surgeons are qualified or experienced to handle complicated side effects from weight loss surgery.

Gallbladder Disease

Some patients may get gallstones and gallbladder issues following severe weight loss. Vomiting and nausea are frequent signs of gallbladder disease. The gallbladder removal may be necessary and advantageous if the patient has stones, and we have already ruled out all the reasons above for nausea.

A HIDA scan can be carried out if the gallbladder ultrasound is negative. This unique examination is used to check for gallbladder dysfunction, additionally known as biliary dyskinesia, this disorder. A weak gallbladder can also bring on similar signs of gallstones.

Unknown Factors

Sadly, there are situations when we are unable to identify the real reason behind persistent nausea and vomiting. Even after a thorough investigation, the symptoms may not have a proper explanation. We can only wait at that point to see if the symptoms become better with time. You could experience this. Fortunately, it doesn’t occur frequently.


These are only a few reasons for constant vomiting after gastric sleeve surgery. As a result, the prevalence of obesity and related medical consequences is growing alarmingly. The metabolic and bariatric treatments can considerably improve your quality of life. Potential issues after metabolic and bariatric surgery can develop anytime, and some patients may endure comorbidities for many years.
