Gastric Bypass Surgery is a form of weight loss surgery that changes your digestive system to help you lose weight by limiting how much you can eat or by reducing the absorption of nutrients, or both. Gastric bypass surgery is performed when diet and exercise haven't worked or when you have serious health problems because of your weight.
There are many types of weight-loss surgery, collectively called bariatric surgery. Gastric bypass is one of the most common types of bariatric surgery. Many surgeons prefer gastric bypass surgery because it has fewer complications than other weight-loss surgeries.
As with any type of surgery, gastric bypass surgery can pose serious risks and side effects. You must make healthy changes to your diet and get regular exercise to help ensure the long-term success of bariatric surgery.

What happens after the procedure?
After gastric bypass, you normally won't be allowed to eat for one to two days so that your stomach and digestive system
can heal. Post that, you’ll begin with liquid diet and then progress to soft foods, and finally to regular foods. You may have limitations regarding eating and drinking.
You'll also have regular medical checkups
to monitor your health in the first few months after gastric bypass. Initially, you may experience changes as your body reacts to the rapid weight loss including:
- Body aches
- Feeling tired, as if you have the flu
- Feeling cold
- Dry skin
- Hair thinning and hair loss
- Mood changes
Gastric bypass can provide long-term weight loss. The amount of weight you lose depends on the type of surgery and your change in lifestyle habits
