Been thinking about undergoing a weight loss surgery in Singapore, or anywhere else for that matter? Before you even decide when and where you’d like to undergo a surgery, you need to make sure that:


  • You’re an adult who’s obese, and have a weight-related issue (like type 2 diabetes).
  • You’re fully aware of the benefits and risks of a surgery (and the emotional toll that comes with it).
  • You’re ready to adjust your lifestyle revolving your diet post-surgery.
  • You have enough discipline and are committed in making changes in your lifestyle to maintain your new weight.
  • You have a body mass index (BMI) of at least 35 (plus a weight-related condition at the same time).


Only after you’ve checked off these items can you move forward and talk to your doctor whether the surgery would be the best option for you. Next, you may discuss these types of weight loss surgery with your doctor:


  1. Duodenal Switch

This complicated surgery will remove most of your stomach. To bypass small intestine, your surgeon will use a gastric sleeve, which limits the amount of food you eat. This surgery method will reduce your body’s chances of absorbing nutrients from food and getting enough minerals and vitamins you need.


  1. Gastric Sleeve

Through this surgery, most of your stomach will be removed, leaving only the gastric sleeve, which is the narrow section of the stomach’s upper part. The surgery could potentially make you eat less by curbing ghrelin, the hunger hormone.


  1. Adjustable Gastric Band

In this surgery, which is done by using a laparoscope, a small band will be placed near the top part of your stomach. There’s a small balloon inside the band which controls how loose or tight the band is. The band limits the amount of food that goes into your stomach.


  1. Gastric Bypass

The most famous type of surgery among the four, the surgery will leave you with only the pouch (the stomach’s very small part), which makes you eat less since the pouch can’t hold too much food.


Please note that regardless of the type of surgery you’ve chosen to undergo, you may experience these risks and side effects:


  • The most common side effects that many would experience include dizziness, increased gas, excessive sweating, diarrhoea, bloating, vomiting and nausea.
  • Other potential serious side effects to watch out for include blood clots forming in legs which can travel to the lungs and heart, leaks from stiches, infection or bleeding. That said, only a small minority of people would get any of these (it’s not that common).
  • Other long-term problems post-surgery vary depending on your surgery method. Discuss this with your doctor.
  • Gallstones may occur and form. Ask your doctor if he’d recommend any supplement after surgery to prevent them, like bile salts.


Once you’ve taken care of everything, your doctor may require you to do these in preparation to your upcoming operation:


  • Avoid herbal supplements, aspirin and any product that contains the substance, a week before your surgery is due.
  • For 24-48 hours before the start of surgery, you’ll only have to drink or eat clear liquids.


Whether you’re choosing to undergo a weight loss surgery in Singapore or anywhere else, the major points mentioned should be thoroughly consider to prevent unnecessary complications.
