Types of weight loss surgery

The three most widely used types of weight loss surgery are:

  • Roux- en- Y Gastric bypass – where your digestive system is re-routed past most of your stomach, so you digest less food which reduces glucose level in body plus increases peripheral glucose utilization which leads to control in diabetes type II.
  • Sleeve gastrectomy – where some parts of the stomach is removed to reduce the amount of food that's required to make you feel full which also control some extent of diabetes.
  • Mini Gatric Bypass – which uses the technique and advantage of both surgeries mentioned above and also help in controlling diabetes.


Life after weight loss surgery

Weight loss surgery can achieve impressive results in terms of the amount of weight lost, but it shouldn't be seen as a magic cure for obesity This plan will include:

  • Carefully controlled diet
  • Regular exercise



As with all types of surgery, weight loss surgery carries the risk of complications; such as:

  • Internal bleeding
  • A blood clot inside the leg (deep vein thrombosis)
  • Malnutrition


Certain risk factors, such as high blood pressure or a BMI of 50 or above, also increase the risk of complications.



As long as a person is willing and able to stick to their agreed plan afterwards, surgery can effectively reduce their weight and treat conditions associated with obesity, diabetes, sleep apnea, hypertension, hypercholesteromia etc. Recent research carried out all over the world found that, on an average:

  • people with a gastric bypass will lose around two-thirds of their excess body weight
  • People with sleeve gastrectomy will lose around 40-60 % of their excess body weight


Both techniques also lead to a considerable improvement (and sometimes a complete cure) of obesity-related conditions, such as diabetes or high blood pressure.


How weight loss surgery is performed

The three most widely used types of weight loss surgery are sleeve gastrectomy based on restriction of food intake by making small stomach and gastric bypass & Mini gastric Bypass which uses a combination of restriction and malabsorption. These operations are usually performed as a type of laparoscopic (keyhole) surgery, where around 4-5 small 5 mml incisions are made in the abdomen, rather than one large incision. The advantage of this type of surgery is it causes less pain afterwards and has a faster recovery time. (90 % patient discharged on next day of surgery). These operations are carried out under general anaesthetia, which means you'll be asleep during surgery and won't feel any pain.


Gastric bypass

Gastric bypass uses special surgical staplers to create a small pouch of stomach. This pouch is then connected directly to a section of your small intestine, bypassing the rest of the stomach and bowel. This means it takes less food to make you feel full and you'll also absorb fewer calories from the food you eat. Sleeve gastrectomy During a sleeve gastrectomy, part of the stomach is removed. This restricts the amount of food that can be eaten and results in you feeling full sooner than normal when eating.


Advantages of Bariatric Surgery


  • 40-70% weight loss depending upon the type of surgery

Results of weight loss surgery

As long as you stick to the diet and exercise recommendations, all types of weight loss surgery can achieve good, and often impressive, results. However, rapid weight loss can cause complications. The weight loss is a gradual process, with:

  • 35% of excess weight lost within six months of surgery
  • 40% of excess weight lost by 12 months
  • 50% of excess weight lost by 24 months


Expect to see a marked improvement in health conditions related to obesity, particularly:
Type 2 diabetes

  • Gastro-oesophageal reflux disease (GORD)
  • Obstructive sleep apnoea
  • High cholesterol

  • Day-to-day pain and discomfort
  • General physical health
  • Mental health


Gastric bypass

A person with a gastric bypass should expect to lose 70% of their excess body weight within two years. The weight loss tends to be more rapid in the first year (60% of the excess weight lost) then slows in the second year, with only an additional 10% weight loss. Again, expect to see a marked improvement in the health conditions above
