Complications Following Gastric Bypass

(Posted by Dr Hani)

As with any other surgery, gastric bypass surgery may cause serious complications. Here are some of the most common complications.

Respiratory Problems

Obese patients are reported to have more respiratory complications after surgery and the same is true for gastric bypass surgery. Respiratory problems are the commonest complications seen after gastric bypass surgery. If a patient has a history of previous respiratory problems (e.g., pneumonia), the chances of having respiratory complications after gastric bypass be even higher. Use of anesthetic drugs poses a risk for an obese patient and this is why special anesthesia protocols are often used in obese patients.


Postsurgical infections are common in patients after gastric bypass surgery. If the patient is already having concurrent health problems like diabetes mellitus, the prevention and control of post-surgical infections becomes more difficult. Your surgeon will prescribe broad-spectrum antibiotics for few days to prevent such infections. If infection becomes localized at the surgery site, the surgeon may need to reopen the site and treat the wound.
