4 Weight Loss Surgeries To Consider for Obesity

    4 Weight Loss Surgeries To Consider for Obesity

    Weight loss is what comes to our mind when we desire to have a ripped and slim physique. And other than all weight and fat loss programs, workouts, and diets, we might also have thought about surgeries. Weight loss surgeries are common nowadays as people feel it is the best way to cut out extra fat easily and quickly.

    Weight loss surgery — or bariatric or metabolic surgery — is usually recommended to obese people. However, there are people who undergo such surgeries for faster weight loss.

    Let’s take a look at why you need to undergo weight loss surgeries and what are the four weight loss surgeries normally advised.

    Why Do You Need To Undergo Weight Loss Surgeries?

    In general, bariatric surgery can be beneficial for those who have a body mass index (BMI) of 40 or higher (extreme obesity) or for those who have a BMI from 35 to 39.9 (obesity). Doctors may also recommend surgery for those with a serious weight-related health problem, such as type 2 diabetes, high blood pressure or severe sleep apnea.

    A doctor suggests undergoing a weight loss surgery when weight loss becomes difficult with typical physical workout and a healthy diet.

    Different Types of Weight Loss Surgeries

    Look at these four weight loss surgeries that you can consider:

    Roux-en-X or Gastric Bypass

    Before the surgery, the surgeon uses general anesthesia that makes you sleep.

    There are two steps for this weight loss surgery:

    The first makes your stomach smaller. With the help of staples, your surgeon will divide your stomach into two: small upper section and large bottom section.

    The top section is called the pouch, which is where all the food you will eat will go. The pouch is the size of a walnut that holds only 28 grams or 1 ounce of food. This will decrease your appetite resulting in weight loss.

    The second step is the bypass. The surgeon will attach a small part of your small intestine to a tiny hole in your pouch. Now, the food you eat will travel to the pouch and through this new opening into your small intestine. This helps your body to absorb fewer calories.

    Doctors can perform a gastric bypass in two ways: open surgery or laparoscopy surgery.

    Vertical Sleeve Gastrectomy (VSG)

    VSG surgery is done with general anesthesia. For this, the surgeon uses a tiny camera that will be placed in your belly, as in laparoscopy. A laparoscopic surgery helps the surgeon to carry out the surgery looking through a screen.

    The surgeon makes 2-5 incisions in your belly and inserts the scope and instruments through these incisions. This procedure removes a major part of your stomach. The remaining section of your stomach forms a tube-shaped stomach, which is about the size and shape of a banana.

    This surgery resizes your stomach and restricts the amount of food consumption as a small stomach cannot hold much food. Additionally, vertical sleeve gastrectomy prompts hormonal changes that stimulate weight loss. Also, it helps relieve obesity-related health conditions like heart disease and hypertension.

    Gastric Band

    Gastric banding is one of those weight loss surgeries that involve attaching a silicone band circling the upper part of the stomach to reduce the stomach size and decrease food consumption. This surgery is approved by the Food and Drug Administration (FDA) as an effective weight loss surgery.

    The surgeon ties the band around the upper portion of the stomach and attaches a tube to the band. They can access the tube via a port beneath the abdomen skin.

    The surgeons inject saline solution into the band to inflate it using this port. The adjustment of the band can alter the degree of constriction around the stomach. The band divides the stomach into two parts – a small pouch on the top with the rest of the stomach below.

    Having a smaller stomach reduces the consumption of food. Also, it keeps the stomach satiated by eating only a smaller portion. This reduces hunger and limits food intake.

    As a plus point, this weight loss surgery allows normal digestion without malabsorption.

    Duodenal Switch

    This is also called biliopancreatic diversion with duodenal switch, and is more complex than other weight loss surgeries. The duodenal switch requires two separate surgeries.

    The first is similar to gastric sleeve surgery and the second redirects food to bypass most of your small intestine. Also, the surgeon reattaches the bypassed section to the last part of the small intestine, allowing digestive juices to mix with food.

    Compared to other weight loss surgeries, duodenal switch helps with more weight loss than the other three. However, this surgery is also most likely to cause side effects or surgery-related problems.

    Also, it causes a shortage of protein, minerals and vitamins in the body. This is the reason why surgeons don’t usually suggest undergoing this surgery.

    Life After Weight Loss Surgeries

    These weight loss surgeries can help with drastic weight loss but it cannot entirely help you to fight against obesity.

    After undergoing any of these weight loss surgeries, you need to change your lifestyle and eating habits. Maintenance of these changes and habits is important to keep obesity at bay. Also, you need to follow the following points:

    • Include healthy food in your diet: Include leafy vegetables, legumes and pulses in your diet which will benefit your overall body.
    • Workout: Regular physical activity like a gym workout, yoga, or any cardiovascular activities can help maintain your weight and burn excess fat.
    • Less junk food: Although it would be difficult for you to avoid junk food completely, you can limit its consumption. Limitations on soft drinks and processed foods help lower fat production in the body.


    Ensure you strictly follow these points to prevent excess fat production in the body. Consult your doctor for any specific instructions and consider your general health before planning a workout routine.

    After undergoing weight loss surgery, you should rest to help recover properly. Take the medicines prescribed by the doctor and follow the diet guidelines.

    After surgery, ensure you don’t indulge in any type of intense physical activity immediately. Start slow and increase the difficulty level eventually.

    These are the four weight loss surgeries that you should know about before undergoing one. Ask your surgeon to explain each surgery properly with benefits and possible risks and complications.
