How Gastric Bypass and Banding Operations Improve Health

Weight Loss Surgery Procedures - Research Into Gastric Reduction Surgery

Health Improvements After Bariatric Surgery

Extremely obese people who have weight-loss surgeries experience dramatic improvements in their health, a study in the Journal of the American Medical Association reports.

Seventy percent to 80 percent of the cases of diabetes, hypertension, sleep apnea and high cholesterol were eliminated or improved in patients who had gastric bypass, gastric banding and other weight-treatment operations.

For the latest study, researchers did a statistical analysis of 136 studies worldwide that included 22,094 weight loss surgery patients. The findings:

• Patients lost an average of 61 percent body weight.
• Diabetes was eliminated in 86 percent of patients.
• Hypertension eliminated in 78.5 percent.
• Obstructive sleep apnea eliminated in 85.7 percent.
• High cholesterol decreased in 70 percent of patients.

Resolution of the diabetes often occurred days after the surgery, before weight loss was achieved, and may be the result of changes in hormones, some of which are related to hunger, brought on by the surgery.

Other Bariatric Studies

Two other studies showed that patients who have gastric bypass live longer than similarly obese patients who don’t have the surgery. The new study found that one in 200 died in the month after the operation, whereas one of last week’s studies suggested that one in 50 die within 30 days after gastric bypass.

Laparoscopic or open bariatric surgery, such as gastric banding or bypass is not an easy solution to morbid obesity and weight loss. It is a serious surgical procedure, involving health risks. To produce lasting weight loss it requires a long-term patient commitment to eating a healthy diet and following a regular program of physical exercise. Life-long use of nutritional supplements may also be necessary. So, before deciding, discuss your options fully with your doctor. © 2003-2008 Bariatric-Surgery.Info - Terms - Contact - Information - Resources - Add URL
