Bariatric Surgery vs Metabolic Surgery

Bariatric surgery refers to procedures used to help patients who struggle with obesity, weight loss and manage obesity-related conditions. Also known as weight loss surgery, the goal of the procedure is reduce the patient’s capacity of digestion and appetite.

In contrast to bariatric surgery, metabolic surgery is specifically intended to address and improve obesity-related conditions such as Type 2 Diabetes Mellitus, heart diseases, hypertension, Obstructive Sleep Apnoea (OSA), and fatty liver.

Metabolic surgery has also been coined as diabetes surgery in recent years, when there is marked improvement in diabetes control in Type 2 Diabetes Mellitus patients who have undergone the procedure.

Surgery, however, does not “cure” diabetes; They help patients achieve better control or sometimes even remission (when your blood sugar levels return to a safe, non-diabetes level long-term).

Types of Bariatric Surgery

In general, bariatric surgery works by either limiting how much one can eat or to reduce the body’s ability to absorb fat and calories. Certain procedures are carried out to achieve both.

Intragastric Balloon

A non-surgical procedure that limits your food intake to smaller portions.

Gastric Sleeve

Helps you feel fuller after eating small amount of food, and feel less hungry in general.

Gastric Bypass (Roux-en-Y Gastric Bypass)

Helps you to feel full quickly and reduce the amount of calories your body absorbs.

Mini Gastric Bypass / One Anastamosis Gastric Bypass (OAGB)

Helps you feel full after eating less food and give the feeling of being fuller for longer.

Adjustable Gastric Band

Helps you feel full after eating less food and give the feeling of being fuller for longer.

Biliopancreatic Diversion (BPD)

Helps you feel full after eating less food and give the feeling of being fuller for longer.

When to Consider Surgery

Bariatric surgery can be considered as an option when patients struggle with obesity, and diet, exercise or medications haven’t worked.

It is also done when patients experience serious health problems because of their weight.

Why It is Done

Besides weight loss, bariatric surgery is also intended to reduce one’s risk of serious weight-related health problems such as:

Who is a Candidate?

In general, bariatric surgery could be an option for people who struggle with obesity (BMI of 32.5 and above) and related issues such as Type 2 diabetes, and unable to lose weight through other methods.

In some cases, people with a BMI of 30 to 34 may also qualify for weight loss surgery if they struggle with weight-related health problems.

How Effective is Bariatric and Metabolic Surgery?

Studies have shown that patients typically lose the most weight after 1-2 years after bariatric surgery. They are then able to maintain substantial weight loss with improvements in associated co-morbidities.

Patients may lose up to 60% of excess weight six months after surgery, and up to 77% of excess body weight as early as 12 months after surgery.

Majority of bariatric surgery patients with diabetes, hyperlipidemia, hypertension and obstructive sleep apnoea experience complete resolution or improvement.

Bariatric and Metabolic surgeries are performed for medical reasons. These are not considered cosmetic surgery. The cost of your surgery whether will be covered by insurance will depend on you specific plan. Some insurance plans do not cover for sole weight loss alone. There will be better chances of qualification of coverage if surgery is indicated for obesity related co-morbidities and medical conditions rather than just weight loss.
