All surgical procedures come with risks, but for most patients, the lasting benefits of bariatric surgery outweigh the risks. Some of the main risks of bariatric surgery include:
- Acid reflux
- Anesthesia-related risks
- Chronic nausea and vomiting
- Dilation of esophagus
- Inability to eat certain foods
- Infection
- Obstruction of the stomach
- Weight regain
Other risks may include:
Dumping Syndrome
Dumping syndrome is actually an adrenaline rush caused by too many carbohydrates entering the intestine too quickly. Symptoms are palpitations, sweating and a weak-in-the-knees feeling. About one-quarter of patients who receive a gastric bypass will experience this. This condition is unusual with the gastric sleeve.
Blood Clots (Rare)
Very few surgical weight-loss patients develop blood clots. Less than 1% of all surgical patients in the U.S. encounter this issue. The bariatric team is very proactive in preventing blood clots. You are given blood thinners during surgery and after. You also use a compression device and ambulate every two hours while in the hospital and at home.
