Common Types of Weight Loss Surgeries and Their Effectiveness

There are many reasons that you might be considering weight loss surgery. Maybe you've tried dieting and can't lose weight, or your health has become so precarious that you need to do something now to lose it. Whatever the reason, you know that weight loss surgery is major surgery with all the encompassing risks. 

You want as much information as you can get to make an informed decision as to which weight loss surgery is the best option for you. This is your guide to everything you need to know about weight loss surgery to make the best decision for your unique circumstances. 

What Is Weight Loss Surgery? 

Weight loss surgery, also referred to as bariatric surgery, is a type of surgery that reshapes, resizes, or changes the shape of the stomach. By doing the surgery, it changes the balance of the gut hormones. 

These hormones tell you when you are hungry and also when you're full. With the change in hormones, you're better able to lose weight and maintain a more healthy lifestyle. 

Also, each type of weight loss surgery requires specific dietary requirements and restrictions. These also aid in your weight loss journey. 

There are two main reasons that you might consider weight loss surgery: appearance and your health. The loss of weight can help improve a variety of health conditions associated with obesity. These include:doctor taking mans blood pressure

Most Common Types of Weight Loss Surgery

When it comes to weight loss surgery, there are a variety of strategies and options. The surgery you ultimately choose depends on your health, goals and physical condition. Each surgery isn't the right one for every patient. Here's a look at the most common types of weight loss surgery:

Gastric Sleeve

Laparoscopic sleeve gastrectomy is a minimally invasive procedure which reduces the size of the stomach by roughly 75%. A sleeve gastrectomy has become the most frequent weight loss surgery due to comparable weight loss to other bariatric procedures. The 75% reduction in stomach size will lead to:

  • Decreased hunger hormone (Ghrelin) production, providing increased satiety (feelings of “fullness”) and hunger suppression
  • Restricted space for food in the stomach, decreasing the amount of food patients can eat in one sitting

Additional improvements in overall health:

  • Type 2 diabetes controlled in 70% of patients
  • High blood pressure resolved in 50% of patients
  • High cholesterol improved in 77% of patients
  • Obstructive sleep apnea resolved in 60% of patients

Gastric Bypass

Laparoscopic gastric bypass is a minimally invasive procedure which separates and reduces stomach size while redirecting your digestive tract to alter food absorption. After a gastric bypass, food travels through the reduced stomach ‘pouch’ and then immediately into the mid-portion of the small intestine. The remainder of the stomach and proximal intestine still take part in the digestion of this food by producing the enzymes and hormones necessary, but their placement further ‘downstream’ within the GI tract allow for altered food absorption. This redirection within the GI tract will lead to:

  • Long-term 60-80% excess weight loss
  • Restricted space for food in the stomach, decreasing the amount of food patients can eat in one sitting
  • Altering gut hormone production which reduce appetite and improve satiety (feelings of “fullness”)
  • Maintenance of over 50% of excess weight loss over time

Additional improvements in overall health:

  • Type 2 diabetes controlled in 78% of patients
  • High blood pressure resolved in 66% of patients
  • High cholesterol improved in 94% of patients
  • Obstructive sleep apnea resolved in 76% of patients

Duodenal Switch

The duodenal switch is a minimally invasive procedure which bypasses roughly ¾ of the small intestine, decreasing food absorption and minimizing hunger in patients. During a duodenal switch, a sleeve gastrectomy is created, and the distal (last portion) of the small intestine is brought up to the ‘emptying’ segment of the stomach and connected. This results in a smaller stomach pouch, as well as a much shorter digestive path for food to travel. The advantages of the duodenal switch are:

  • Increased potential for food intake compared to bypass
  • Less limiting for post-operative food selection
  • Long-term 80-85% excess weight loss
  • Offers the most weight loss in comparison with other bariatric procedures

Additional improvements in overall health:

  • Type 2 diabetes controlled in 86% of patients
  • High blood pressure resolved in 79% of patients
  • High cholesterol improved in 70% of patients
  • Obstructive sleep apnea resolved in 86% of patients
