Complications Associated With Gastric Sleeve Surgery

Gastric sleeve surgery is an invasive surgery in which the surgeon will make an incision between the stomach and decrease the size of the stomach by removing 80% of the upper abdomen, which is beneficial in losing weight.

Decreasing the size will restrict the amount of food consumed; hormonal changes also helps in losing weight. Patients who are obese and are at a high risk of having heart disease, high blood pressure, stroke, or cancer are recommended to undergo gastric sleeve surgery to reduce the risk factors caused due to obesity.

Specialists of gastric sleeve Frisco can help you in examining the problem and provide effective solutions. 


Gastric sleeve surgery causes many adverse effects, which last for a short or long period.

  • Excessive bleeding

Patients undergoing surgery have a risk of having excessive bleeding. If the surgery goes wrong while incising the main blood vessel, it could lead to excessive bleeding, which further causes circulatory shock. 

  • Infection

There is a high risk of infection. If the surgical instruments are not sterile, the microorganism can be transmitted to the patient and cause further damage.

  • Blood clot

If the patient is a smoker or has poor hygiene, there is a risk of having clot formation in the body after the surgery as a response to the trauma for the body that is interpreted as an injury.

  • Gastric leaks

It is a life-threatening complication that occurs when a gap develops somewhere along with the staple line closure. It causes the gastric juice to exit into the abdominal cavity, which causes multiple organ failures and even causes septic shock.

  • Hernia

Patients who are obese are at a high risk of having a wound hernia (bulge after the surgery). Doing physical activities that increase pressure in the abdomen, such as weight lifting, coughing, etc., causes the bubble to grow and result in a hernia.

  • Malnutrition

By decreasing the size of the stomach, the patient will suffer from protein or microelements deficiency such as iron, folate, and vitamin B12.

Patients after surgery who do not follow the diet plan prescribed by the doctor are at high risk of having malnutrition.

  • Gastric reflux

Increased abdominal pressure will make the esophageal sphincter weak, due to which the acidic juices will move against the gravity to the esophagus and cause gastric reflux.

If you have undergone gastric sleeve surgery, you should be ready for these complications and ask your doctor about the possible outcomes of the procedure.
