Potential Side Effects of Stomach Stapling

Stomach stapling can be a beneficial procedure for obese and morbidly obese people. However, there are also a few side effects that need to be considered when discussing the weight loss option.

Surgery Side Effects

Being an abdominal surgery, the gastric bypass or stomach stapling can have the same side effects as any surgery. The incision wound may get infected in some cases. Fever is the most common sign of infection. Oral or intravenous antibiotics will fight off the infection.

Blood clots can put your life at risk, however, they are very rare and should be detected post surgery. Blood thinners can reduce the risk of blood clots.

Hernias may also occur post surgery. 1 out of 10 patients can develop hernias which require an additional surgery to be removed.

After the surgery, you will be under medical supervision for 5 days, to make sure the surgery doesn’t have complications.


The stomach stapling surgery will be performed by creating a small pouch which will only allow you to eat small amounts of food at a time. If you fail to chew your food properly or if you eat larger amounts of food at a time, you may become nauseous.

Vomiting may also occur when the stoma, which is the opening between the pouch and the rest of the stomach, is too narrow. This will cause the food to be thrown up instead of being sent to the intestinal tract. The stoma can be enlarged with an endoscopic balloon, and this procedure does not require surgery.

Stomach Cramps

If you eat hot foods or food high in carbs, or if the food is not properly chewed, this may give you stomach cramps.


Gallstones are formed due to the large amounts of cholesterol that gather in the gallbladder. Over 30% of people with gastric bypass develop gallstones.

Stomach Leakage

If the pouch ruptures, the contents of the stomach may leak in the abdominal cavity, and this may be very dangerous for the other vital organs, due to the high concentrations of acid from the gastric acid.

The rupture can be sealed naturally, but in some cases surgery may be needed.

Nutritional Deficiencies

Nutritional deficiencies are common in people with stomach stapling. Anemia, metabolic bone disease or osteoporosis can occur.

Nutritional deficiencies can be prevented though an optimal intake or foods that are rich in iron, calcium, magnesium or vitamin B12. Supplements may also be prescribed.

Stomach stapling is an invasive weight loss solution that can help you reach your target weight in a few years. You must set yourself some realistic goals, otherwise you won’t be able to carry out your weight loss plan.

If you fail to follow your nutritionist’s dietary recommendations and continue eating high calorie content foods and processed foods, you may not lose any weight at all after the surgery. You must be aware of the fact that the stomach stapling itself will not make you thinner; you need to change your lifestyle and diet to be able to lose weight.
