Weight loss surgery is often a good choice for those needing to lose a substantial amount of weight. Many people who have this form of surgery have tried several times to use diet, physical training and medications to lose the weight and they have all been unsuccessful. Weight loss surgery is a life changing process and that often results in a significant amount of weight loss. While there are many benefits of this surgery, there are potential risks involved, as well.

Before a physician recommends any patient to have weight loss surgery, he or she will carefully take into consideration each patient and their case. Sometimes, even though an individual is very overweight, he or she might not be an ideal candidate for the surgery. This is in most instances because that person has other health issues or illnesses that will become worse after this surgery, or that there are increased risks of developing serious side effects and postoperative complications.

If you are considering any type of weight loss surgical treatment, it is crucial that you realize and understand the dangers of the surgery. There are both short term side effects and some long-term side effects. Right after operation, patients will feel some degree of discomfort. This is due to the place of the cut. With a laparoscopic surgery, the incisions are smaller and the healing and irritation in the zone is less than with an open procedure. For patients that have an open procedure, such as in a gastric bypass, there will in most instances be more discomfort while the incision heals. During the first weeks, patients will only be able to accept a liquid diet. Anything other than liquids can irritate the system and result in nausea, vomiting and bowel disorders. In the following weeks more food can be added to the diet, but if too much or the wrong types of food are added, it can as well as causes detrimental side effects. When the stomach and incision has completely healed, these side effects in most c ases subside.

In addition, patients undergoing certain types of weight loss surgery are more vulnerable to developing a condition called "dumping". This is when food is passed very promptly from the stomach to the large intestines. Due to that, the patient will go through nausea, abdominal cramping, sweating, dizziness and diarrhea. Almost all gastric bypass patients describe this condition, but those who have the Lap-Band surgery rarely report this as a side effect.

Other, more serious side effects of this surgery can include stomach ulcers, acid reflux, heartburn, bloating from gas, constipation, difficulty swallowing, nausea and vomiting, dehydration and in serious cases, death. With the Lap-Band weight loss surgery, the band can deflate causing leakage or the band can slip. In other cases, the band can erode into the stomach requiring a second surgery or the stomach pouch can become enlarged. Sometimes, weight loss surgery can also cause blockage of the stomach, which can be caused by food, swelling, improper band placement and stomach twisting. There are also other side effects from this category of surgery that a physician can discuss with each patient.
