How Many Types of Weight Loss Surgery are There?

Weight loss surgery has emerged as a reliable solution for those battling with obesity. There are several types available, including the gastric sleeve, gastric bypass and gastric balloons. Let’s delve deeper into these and the broader world of weight loss surgeries.

Gastric Sleeve (Sleeve Gastrectomy)

This surgery involves removing about 80% of the stomach, leaving a tubular "sleeve"-like section. This reduced size helps patients feel full faster and thus, consume less food.


  • Promises significant weight loss results.
  • With part of the stomach removed, fewer hunger-inducing hormones are produced.
  • There's no introduction of foreign objects into the body.


  • Being irreversible, there's no going back after the surgery.
  • There's a potential for nutrient deficiencies given the reduced stomach size.

Gastric Bypass

This procedure involves 'bypassing' a large portion of the stomach. A small section is then linked to the small intestine. This means it takes less food to make you feel full. You'll also absorb fewer calories from the food you eat.


  • A highly effective procedure for significant and sustained weight loss.
  • Improves or resolves conditions like type 2 diabetes and hypertension.
  • Reduces the amount of food the stomach can hold while limiting calorie absorption


  • More complex than some other weight loss surgeries, with higher risk factors
  • Potential for long-term complications such as vitamin/mineral deficiencies and dumping syndrome

Types of Weight Loss Surgery

Gastric Balloons

This non-surgical procedure inserts a deflated balloon into the stomach. Using an endoscope, the balloon is then inflated. This balloon, filled either with air or saline, takes up space in the stomach. This reduces its food capacity.


  • The non-surgical nature makes it less invasive.
  • Quick procedure and hospitalisation time.
  • A suitable option for those ineligible for other surgical methods.


  • A temporary measure, with balloons typically removed after six months.
  • Some patients report discomfort or nausea.

Understanding Bariatric Surgery

Bariatric surgery's rising demand:

The rise in obesity globally has led to an increased demand for weight loss surgeries. With advancements in medical science, these surgeries have become safer. The post-operative recovery time has also reduced significantly.

Post-operative care:

After undergoing any weight loss surgery, post-operative care becomes crucial. This involves following the dietitian's recommended dietary changes. Engaging in regular physical activity, and attending follow-up appointments is also important.

The cost factor:

Cost is a considerable factor for many patients. While these surgeries can seem expensive initially, one must consider the long-term benefits. These include improved health, reduced medical bills in the future, and enhanced quality of life.


Procedures like the gastric sleeve, gastric bypass and balloons are becoming more popular. Individuals can now make informed decisions based on their health requirements and desired outcomes.

Most patients notice significant weight loss within the first six months post-surgery. The extent and speed depend on the surgery type.

3. Is the weight loss permanent?

Maintaining weight post-surgery involves lifestyle changes. Adhering to recommended dietary and physical activity guidelines mean the weight loss can be long-lasting.

4. Are there age restrictions for these surgeries?

While many surgeons operate on patients aged 18-65, there are always exceptions. It depends on the individual's overall health and specific circumstances.

5. What's the psychological impact of these surgeries?

Patients often report improved self-esteem and quality of life. However, significant weight loss can be a significant adjustment. Some may need psychological support during this transition.
