Bariatric surgery is an extensive surgery that physically decreases the size of the stomach. Although bariatric surgery has been known to relieve chronic back pain associated with obesity, the surgery itself may cause mild back problems.

Types

There are three main types of bariatric surgery. Gastric bypass surgery involves stapling off a small section of your stomach, while lap-band surgery involves wrapping a silicone band around the stomach to section off a small pouch. Gastric sleeve surgery is the least invasive, involving small incisions and a laparoscopic tool.

Complications

As with any surgical procedure, bariatric surgery may involve a series of medical complications and side effects. Complications include infections, constipation, dumping syndrome, nutritional deficiencies and back pain.

Loose Skin

If the bariatric surgery leads to a significant amount of weight loss, the person may experience excessive amounts of loose skin hanging from the breasts, abdomen, limbs and back. This loose skin is heavy; as it weighs on the body, it can cause significant back pain.

Constipation

Constipation is a common side effect of bariatric surgery. With constipation, waste materials become blocked in the lower intestine, causing pressure and pain in the lower abdomen and back.

Lack of Activity

Although most people are able to return to a normal schedule within a week after bariatric surgery, some people find the recovery process takes much longer. Spending significant time reclining in a bed or chair often leads to back pain. It is important to stretch and maintain some form of activity after bariatric surgery.
