Gastric Sleeve Surgery for Weight Loss Restrictive Weight Loss Surgery

A gastric sleeve surgery is restrictive in nature, which means it helps reduce the amount of food you intake. It involves “restricting” and limiting the size of the stomach to aid in weight loss. This makes you eat smaller and more controlled food portions. It is important to keep in mind that a weight loss surgery like gastric sleeve is a lifetime commitment of staying on a stringent diet plan.

How is Laparoscopic Sleeve Gastrectomy Done?

About two-thirds of the left side of the stomach is removed laparoscopically and makes the stomach look like a tube with a capacity of 60 cc to 150 cc. The part of the stomach that produces Ghrelin hormone, which stimulates appetite and promotes fat deposition in the body is removed. 


  • Preservation of the stomach function
  • It does not require disconnecting or reconnecting the intestines
  • It is a technically simpler procedure than gastric bypass or duodenal switch (rarely done)
  • The stomach is reduced in volume but tends to function normally so most of the food can be consumed, albeit in small quantities
  • Eliminates the portion of the stomach that produces hunger hormone – Grehlin
  • No dumping syndrome because the pylorus is preserved
  • Minimises the chance of an ulcer occurring
  • By avoiding the intestinal bypass, the chance of intestinal obstruction (blockage) anaemia, osteoporosis, protein deficiency and vitamin deficiency are almost eliminated

It is important to note, that this procedure is irreversible.

Gastric Sleeve Surgery Results

As important as it is to know the process you are about to undergo, it is equally crucial you understand the results of the surgery. Due to stomach stapling and restriction, you will eat smaller portions and feel full. In fact, your stomach may only be able to handle fluids and soft foods for a while.

You may also have a much faster metabolism, which may cause you to have diarrhea and nausea. You need to ensure that between the lower quantity of food and higher excretion levels, your body maintains necessary nutrient levels. Feeling lightheaded and shaky can also be another side effect of gastric sleeve surgery. For this reason, keep a bottle of water close-by, to help you constantly hydrate your body. Consult your doctor post-surgery, on whether or not to resume regular activities. You may be required to take rest for up to 6 weeks to avoid straining your recovery.

Over time you will be able to increase the types of food you intake as part of your diet plan. However, even after you include solid food into your diet, make sure that you eat smaller portions. Eating too much can cause you to feel nauseated. Keep in mind, this weight loss surgery is only as effective as your efforts post surgery. If you continue to have unhealthy habits, you can go back to gaining weight.
