Surgery for Weight Loss – The Types

Nov 4th 2015 at 9:00 AM


Obese people will have a tougher time in losing excess weight. It also takes longer to attain the target weight. For them the easy route can be the surgery for weight loss. But it is not done for all and only for those who really need it. It is not something that happens in everyday life. It is done also as a last resort when all other methods have failed to attain weight loss.

Types of surgery for weight loss

The surgery for weight loss is of four types.

  1. Gastric banding: Gastric banding is to insert a band around the top portion of the stomach to make it smaller and holds lesser amount of food. This will make the person feel fuller without filling up the stomach. The only thing to note here is that the food must be consumed much slower. The people will no longer be able to eat as much as he used to take. The band is adjustable with a balloon like structure that controls the tightness. It is a small surgery done laparoscopic. This band will separate the stomach in two portions and the food takes time to travel from the upper to the lower portion.

  2. Gastric sleeve is the surgery for weight loss where a part of the stomach is removed to make it smaller. The upper portion of the stomach is made as a small strip or sleeve as a result the person eat slow and lesser. This surgery will also reduce the hunger hormone- ghrelin, making the person feel less hungry. People who are too obese or sick will have this as a primary treatment. Cutting down the stomach will not affect the nutrient absorption as the intestine stays the same. Only the calorie intake is reduced.

  3. Gastric bypass: This surgery will make a small stomach pouch through which the food passes. The rest of the stomach will no longer be part of the digestive tract and the food will completely bypasses it. This pouch holds only a small amount of food. The food will go directly to the small intestine from this pouch and the rest of the stomach stays the same.

  4. Duodenal switch is the most complicated where most of the stomach portion is removed. Only a small gastric sleeve is left behind and the food will be bypassed to the small intestine. This surgery will leave the person eating very less and the body unable to completely process or absorb the nutrients. This will result in nutrient deficiency later.


Benefits, risks, and side effects of surgery for weight loss

The result of the surgery will be that there will be weight loss alright. But it may also come with complications or side effects. Weight loss surgery can be beneficial for the extreme obese people and those who have diabetes or blood pressure.

The side effects can be vomiting, excessive sweating, diarrhea, nausea etc. Slow eating can reduce the digestive related symptoms. Internal bleeding, infections or blood clots can pose some problems later on so one has to be very sure before going for the weight loss surgery.
