There are three basic types of weight loss surgeries to help people who are considered morbidly obese. Restrictive, malabsorptive, and a combination of the two are all commonly performed on weight loss patients. These surgeries all have one goal, which is to help patients with a lot of weight to loss, shed those excess pounds. Each surgery is different and each has its own benefits and disadvantages.
When looking into having weight loss surgery, a health care professional will work closely with you to determine which type of surgery will benefit you the most. For some, the least invasive type of surgery is the best and for others, a more radical approach is needed. Whichever surgery is determined is right for you, it is vital that you research the surgery and let your doctor know of any concerns you might have prior to the surgery.
Restrictive plus Malabsorptive
One type of weight loss surgery that is commonly performed on obese patients is a combination of restrictive and malabsorptive. This surgery is called the Roux-en Y surgery, or is more commonly known as the gastric bypass. This surgery is a very poplar approach to weight loss surgery. It has been performed for several years with a high success weight.
During this surgery, the stomach is stapled to make a new, smaller stomach pouch. Then, attaching, or stapling a part of the intestines to the smaller stomach pouch bypasses most of the stomach and part of the intestines. The result is that you cannot eat very much at mealtimes and fewer nutrients and the body absorbs calories.
Pros and Cons
Just as with other types of weigh loss surgery, there are both advantages and disadvantage of this surgery. Patients that have the gastric bypass can often expect to loss a lot more weight initially following the surgery. Doctors have perfected this surgery to use the least invasive methods as possible. This means a less recovery and healing time after the surgery is performed. Another benefit of this surgery is that it has been performed for many years in the United States and patients can expect a very experienced doctor.
There are disadvantages to the gastric bypass, as well. First, there will be more cutting and stapling of the stomach and bowels than with other forms. In comparison to the Lap-Band procedure, there is a greater risk for operative complications during the procedure. Also, because part of the digestive system is bypassed, the patient will lose some of the important nutrients and may need repeated screening and supplements.
This procedure may also cause some medical problems such as anemia, hair loss and bone density loss due to the lack of nutrients being absorbed by the body. The gastric bypass is difficult to reverse and is not adjustable based on the patients needs.
Also this form of weight loss surgery has a higher mortality rate that with the Lap-Band or vertical banded Gastroplasty procedures. Patients with this surgery also report a high rate of the dumping syndrome, which leads to cramping, sweating, nausea and diarrhea.
