Do I qualify for Laparoscopic Sleeve Gastrectomy, Laparoscopic Gastric By-Pass or Laproscopic Gastric Banding?

You may be a candidate for obesity surgery if:

  • Your body mass index (BMI) is 40 or more
  • Your BMI is between 35 and 39.9 and you are suffering from a serious obesity-related health problem (e.g. heart disease, type 2 diabetes, or severe sleep apnoea)
  • You have a thorough understanding of obesity surgery and the lifestyle changes it will require you to make

What are the lifestyle changes I need to make after weight loss surgery?

The very first thing you need to practice is eating small quantities of food and eat them slowly. You will be required to visit the doctor / surgeon every month for at least one year or as advised by your doctor for follow-up. Weight loss will begin soon after surgery and will continue for up to 1.5 years. 60% of patients don’t require medication for obesity-related health conditions after the weight loss surgery. They also experience higher energy levels, enhanced mood, boost in self-esteem and improved body image. Obesity patients should take care to not overeat or slack in exercises to keep themselves in shape.

How much weight can I expect to lose after undergoing Laparoscopic Sleeve Gastrectomy, Laparoscopic Gastric By-Pass or Laparoscopic Gastric Banding? How long will it take to lose weight?

The average weight loss with laparoscopic gastric banding is about one-third to one-half of the excess weight you are carrying. Weight loss occurs over a period of two years, with most of the weight lost in the first year itself.

The average weight loss with laparoscopic gastric bypass surgery is same as the banding weight loss surgery. However, patients suffering from morbid obesity (BMI over 50) can lose up to 70% of their excess weight. It may take up to 6 to 18 months to experience all results.

With Laparoscopic Sleeve Gastrectomy, a patient with a BMI above 40 can lose 40-50% of excess weight in two years whereas a patient below 40 can lose 60 to 80% of weight within three years of surgery.

Can my Laparoscopic Sleeve Gastrectomy, Laparoscopic Gastric By-Pass or Laparoscopic Gastric Banding surgery be reversed in the future?

Yes, you can reverse both Laparoscopic Gastric By-Pass and Laparoscopic Gastric Banding surgeries in future. However, doctors advise against it as it may lead to several health complications. Laparoscopic Sleeve Gastrectomy, on the other hand, cannot be reversed.

What happens if I don't follow dietary guidelines after weight loss surgery?

Ignoring dietary guidelines following surgery can slow down weight loss and lead to health complications. Many obesity surgery patients who overeat and consume meals high in fat and sugar experience “dumping syndrome,” which leads to sweating, fatigue, and diarrhoea. It can also cause vomiting, and band slippage in banding surgery patients.

Why is exercise important after weight loss surgery?

Exercise helps you to build muscle and burn calories. If you don’t exercise, your body will consume your unused muscle, making you lose muscle mass and strength.

Can I consume alcohol after undergoing weight loss surgery?

It is suggested that you completely refrain from drinking alcohol at least for a year. Alcohol can hamper weight loss and can affect you immensely as your drinking threshold / capacity decreases.

Can I smoke following obesity surgery?

It is advised that you quit smoking because smoking can lead to cardiovascular diseases, a major health risk of obesity. If you are taking steps to improve your health with the help of obesity surgery, why ruin it with smoking?

Can I get pregnant after undergoing surgery?

You should avoid getting pregnant for at least one year after the surgery. After a year, when you have resumed your regular diet, you can try for pregnancy.
