Weight Loss Surgery

Weight loss surgery also know as Bariatric surgery includes a variety of procedures performed on people who are obese and cannot lose weight through diet or exercises or have severe health conditions caused by obesity.

The surgery makes the stomach smaller or sometimes changes the small intestines.

Who can get this procedure done?

  • People who are severely obese with Body Mass Index (BMI) of 40 or over, OR
  • People with BMI of 30 or over with an existing health condition or newly diagnosed Type II diabetes.

There are different types of weight loss surgery. They often limit the amount of food you can take. Some types of surgeries also affect how you digest the food and absorb nutrients.

When determining eligibility for bariatric surgery for extremely obese patients, psychiatric screening is critical; it is also critical for determining postoperative success. People with BMI of 40 and above have a higher risk of depression, and half of bariatric-surgery candidates are depressed.

Types of Surgical Procedures

  1. Gastric bypass
  2. Sleeve gastrectomy
  3. Adjustable gastric band
  4. Biliopancreatic diversion with duodenal switch

Each of these procedures has its own advantages and disadvantages.

Some Misconceptions

  1. Most people who have metabolic and these kinds of surgeries regain weight

Fact:

As many as 50% of the people regain a small amount of weight(approximately 5%) two years or more after the surgery.

  1. The chances of dying from these surgeries is more than the chance of dying from obesity.

Fact:

Data involving nearly 60,000 bariatric patients from ASMBS Bariatric Centers of Excellence database show that the risk of death within the 30 days following bariatric surgery averages 0.13 percent, or approximately one out of 1,000 patients. This rate is considerably less than most other operations, including gallbladder and hip replacement surgery. Therefore, in spite of the poor health status of bariatric patients prior to surgery, the chance of dying from the operation is exceptionally low.

Consult your physician and get a detailed update of these procedures before deciding.

After this surgery, women may have a lower risk of heart disease than men, a new study suggests.

All patients had a significant reduction in their heart disease risk after weight-loss (bariatric) surgery. But, women had a 41 percent reduced risk while men had a 35.6 percent reduced risk, a roughly 20 percent difference, researchers reported.

“This study shows there is a gender disparity in cardiac outcomes for patients undergoing bariatric surgery,” said lead study author Dr. John Morton, director of bariatric surgery at Stanford Health Care in Palo Alto, California

“The findings suggest that women may have an enhanced mechanism of response to bariatric surgery, which leads to greater normalization of biochemical cardiac risk factors,” he said in an ASMBS news release.

Eating Post the Bariatric Surgery

Normally after the surgery, the patient is restricted to a clear liquid diet. This diet continues till the stomach is somewhat recovered post surgery.

The next stage is to provide blended or pureed sugar free diet for at least two weeks. Carbohydrate rich diet is avoided in the initial period after the surgery.

Many patients have to take multivitamins for life in order to make up for the reduced absorption of essential minerals. Also because they cannot eat large quantities  of food, physicians recommend a diet rich in proteins but low in fats.
