Slippage
In order for the band to function properly it must be correctly positioned on the stomach. Gastric banding can slip that is twist out of position. Typically the band does not slip but actually the stomach slips above the band. A slip typically occurs in about 2% of all operations.

Slippage can occur for a variety of reasons like over filling resulting in vomiting can be a cause. Slippage can cause reflux and difficultly with foods and weight loss can be affected. You may require a X-ray to obtain if the gastric banding has slipped. Some slippages if caught early enough can be corrected by removing all saline from the band and allowing the stomach to heal and then gradually re-filling. Slippage may require re-operation to reposition the band and in extreme cases gastric band removal. If a band is removed for slippage it generally can be replaced after a healing period.

Band Erosion
Gastric banding has been known to erode into the stomach. Erosion is a rare complication and is typically known in the older types of bands. This occurs again occurs in about 2% percent of patients. It occurs when the stomach tissue over-growing around the band until the band is on the inside of the stomach instead of the outside. Erosion will involves gastric band removal, sometimes surgical, although it rarely is a life-threatening situation.

Infection
With all surgical procedure there is always the slight risk of infection. Infections can usually be treated with antibiotics and in rare cases may necessitate removal. Always make sure you are in top health prior to your surgery or adjustments without colds or drugs that may compromise your immune system. Notify your doctor immediately if you suspect you may have an infection of any type.

Stretched Pouch
This is a complication that can be avoided by simply not overeating. Learn to stop eating the moment you feel satisfied and avoid continuous packing food into your stomach when full. As this willcause it to stretch and food may back up into your esophagus causing you future discomfort and problems.

Gastric Band Hardware Difficulties
Ports have been broken and tubing punctured usually during the filling process and this risk is reduced by using experienced practitioners and using fluoroscope to locate the port before hand. However, broken ports and punctured tubing are relatively simple matters to fix but can be frustrating for the patient. The problem has been addressed with newer port designs.

Reflux
Reflux is associated with a too tight gastric band causing stomach fluids to back up into the esophagus and damage the delicate tissues not strong enough to cater for acidic stomach juices. If you are experiencing mild reflux talk to your doctor about preventative measures such as diets for after gastric banding surgery or medications. If your reflux is a persistent problem speak to him immediately, don’t complicate the issue by waiting hoping it will get better without intervention.

These are the main risks related with Gastric Banding.

Side-effects are an unwanted by product of the Gastric Banding Surgery but are generally temporary effects of the Surgery, afterwards you are likely to have bruising, pain and swelling around the wounds left behind from the surgery.

You may feel or be sick after eating, especially if you try to eat too much. Your restricted diet may cause some shortage of nutrients so you may consider taking multivitamin tablet as a supplement.

Complications caused from Gastric Banding occur during or after the surgery, but most people are not affected. Some possible complications of Gastric Banding Surgery include a reaction to the anaesthesia or excessive bleeding during or soon after surgery for this case a  blood transfusion may be required.

Some of the specific gastric banding complications:

* Wound infection. Antibiotics are given during surgery to help prevent this.
* For up to six weeks after the operation, it is possible to develop a blood clot (DVT) in the veins in the leg. This clot can break off and cause a blockage in the lungs. In most cases this is treatable, but it can be a life-threatening condition. Compression stockings, intermittent compression pumps and blood-thinning injections are used to help prevent DVT.
* There is a risk that during the operation other organs in the abdomen may be accidentally damaged.
* There is a risk that the gastric band may slip out of place, break or erode through the stomach wall. This may require further surgery or removal of the gastric band.
* It is possible you may fail to lose sufficient weight or regain weight, and some patients have further weight loss surgery.
* If you lose weight rapidly, there is a risk of developing gallstones in your gallbladder. These can be painful. Your surgeon may remove your gallbladder during surgery.

Before any surgery you should ask your surgeon to explain how these risks apply to you. The exact risks will differ for every person.
