Gastric Sleeve Surgery Complications

Possible Complications of Gastric Sleeve Surgery

Gastric Sleeve Surgery Complications can occur with any surgery. It’s important to understand each risk and complication in terms of Gastric Sleeve surgery. With a surgery that removes more than 50% of the stomach, it isn’t unlikely that complications may occur. While the latest medical technology makes performing the surgery easier than before, surgeons should discuss all possible risk factors for those choosing to endure Gastric sleeve surgery.

Gastric Sleeve Surgery Complications

Weight Gain

Choosing weight loss surgery means a lifelong commitment to eating right and becoming healthier. Just because one’s stomach is made smaller, if they are consuming high-fat and high-sugar foods, they can still gain weight. Those with a high body mass index (BMI) may discover they must undergo a second gastric sleeve to reduce their weight if they are not committed to their lifestyle change.


During the Gastric Sleeve procedure, the stomach is stapled on both sides to create a smaller area to consume food. There is a possibility that these staples can loosen, which can lead to leaking. These leaks can contain gastric content that, if exposed, can become fatal if it comes in contact with other organs. If this occurs, a patient will undergo a second operation immediately to repair the leaks.

Trouble Eating / Nausea

Many patients find it hard to eat food, let alone smell it. This can lead to the feeling of nausea. However, this can be potentially dangerous if a patient becomes malnourished. If this occurs, oftentimes, a nutritionist will suggest a patient stay in the soft foods diet portion a little longer than the average patient.

Blood Clots or Infections

Surgeons tell patients to remain immobile for a long period of time after surgery. However, this can lead to blood clots in the leg due to inactivity. Oftentimes, patients are given medications that thin the blood, so this doesn’t occur. The legs are often elevated to prevent this too.

With any surgery, the risk of infection is prevalent. However, after gastric sleeve surgery, the chance is greater because of the chances of leaks. If infection occurs and is minor, antibiotics will be prescribed. If the infection is more severe, a more aggressive procedure may occur.

Some other possible complications can include (and are not limited to): problems with the sutures, obstructed stomach, vitamin deficiencies, heartburn, heart attack, stroke, and depression.

Always consult a doctor if any new symptoms or discomforts occur as a result of gastric sleeve surgery. This allows them to fully examine you and ensure your overall health is protected and secure after gastric sleeve surgery.

Risks of Gastric Sleeve

With any surgery, there are risks. For those partaking in Gastric Sleeve surgery, they may include blood clots, leakages, bleeding or infection. The bariatric surgeon will review all potential complications and risks with a patient prior to surgery.

Before deciding to endure Gastric Sleeve surgery, the risks and the overall changes made to one’s life should be considered. Choosing weight loss surgery means one is committed to a lifelong journey of eating healthy food and being active.
