Why do nausea and vomiting occur after gastric sleeve surgery?
There can be several reasons for nausea after gastric sleeve. Firstly, the stomach is reduced in size after the operation, which leads to changes in your digestive system. A smaller stomach can mean you feel full more quickly when eating. In this case, your body needs time to adjust to the new situation.
Secondly, the anaesthetics and painkillers used during the operation can also cause nausea and vomiting. These side effects usually disappear within a few days.
Thirdly, you may need to follow strict dietary rules during the postoperative phase. This could result in eating less due to the reduced size of the stomach and sometimes eating very quickly. Eating quickly can also cause nausea.
Finally, after gastric bypass surgery, hormonal changes can occur in your body. This can also lead to nausea and vomiting in some people.
These issues are usually temporary and will disappear over time. However, if these symptoms persist for a long time or are severe, it is important to consult your doctor.

Gastric Stenosis after Gastric Sleeve Surgery?
Gastric stenosis, also known as narrowing or constriction of the stomach, can occur after a gastric bypass operation. This is a common complication affecting approximately 2-3% of patients.
The main cause of gastric stenosis is the formation of scar tissue at the surgical site, which can narrow the opening between the stomach and small intestine. This may lead to difficulties in food passage and symptoms such as nausea, vomiting, heartburn, and abdominal pain. Gastric stenosis may couse vomit after gastric sleeve surgery.
If left untreated, gastric stenosis can cause serious complications like malnutrition and dehydration. It is therefore important to address this problem promptly by consulting your doctor.
Treatment options for gastric stenosis may include endoscopic dilation, where a balloon is inserted to widen the opening in the stomach, or surgery to remove scar tissue.
