What are the benefits of weight loss surgery?

Carrying excess weight for long periods of time can put you at risk for developing serious medical conditions, including heart disease, diabetes and cancer. It can also affect your mental and emotional health.


Weight loss surgery is a treatment that helps you gain control of your weight. It works in partnership with healthy choices, exercise and lifestyle changes. Whether you’re motivated by medical reasons or personal ones, improvements in overall health and well-being are often reported after surgery.


The benefits of weight loss surgery include:


Safe and effective weight loss

Weight loss surgery can help you lose weight — and continue to keep it off. While weight loss varies from patient to patient, about 60% of excess weight is typically lost after surgery.


Improvements in your health

Weight loss surgery can improve several weight-related medical conditions, including:

  • Type 2 diabetes
  • Hypertension
  • Heart disease
  • Sleep apnea and other respiratory disorders
  • Nonalcoholic fatty liver disease
  • High cholesterol


Many people are also able to reduce or eliminate the medications they take for conditions such as diabetes, hypertension and acid reflux.


For women in their child-bearing years who are considering having children, the weight loss that occurs as a result of bariatric surgery can improve fertility.


Increased energy and interest in physical activity

Significant and sustained weight loss often results in a notable increase in energy levels. This means everyday tasks become easier, and many people experience a greater interest in physical activity.


Weight loss can also provide relief from joint pain and reduce dependence on pain medication.


Greater self-confidence

Carrying excess weight can affect a person’s emotional and mental health. Feeling trapped in a cycle of losing weight, only to regain it later, can be incredibly frustrating. In addition, obese individuals may feel embarrassed about their weight and avoid social activities due to body image issues.


Weight loss surgery is a treatment that can help a person lose weight and keep it off. After losing excess weight, many people feel more self-confident, as well as mentally and emotionally balanced.

Am I a candidate for weight loss surgery?

Weight loss surgery, or bariatric surgery, is a procedure that can help you lose weight and reverse the dangerous side effects of being overweight. While it’s a powerful tool, your long-term success depends on your ability to make permanent lifestyle changes.

Is Weight Loss Surgery Right for Me?

The following considerations are important in determining whether weight loss surgery is right for you:


Your BMI and health conditions play a role

Body mass index, or BMI, is a screening tool to determine if a person’s weight puts him or her at risk for health problems, including heart disease, diabetes and cancer.


Weight loss surgery is for people with a BMI of:

  • 40 or higher
  • At least 35 with an accompanying weight-related health condition, including type 2 diabetes, hypertension, heart disease, sleep apnea and other respiratory disorders, nonalcoholic fatty liver disease, high blood pressure or high cholesterol


You have a history of unsuccessful weight loss

Weight loss surgery may be right for you if you have trouble losing weight and keeping it off, suffer chronic health conditions and are limited from daily activities because of your weight. The procedure can help you lose weight, and Houston Methodist’s comprehensive care team will provide you with the support needed for long-term success.


You have a positive attitude and determination to succeed

No two people struggle with their weight for the same reasons — but some factors include:

  • Stress and anxiety
  • Social factors
  • Major life changes
  • Past trauma


Weight loss surgery can help you lose weight, but only when it’s paired with lifestyle changes. To ensure your success, you will need to address any personal or social issues that may prevent you from making the healthy choices needed for weight loss. Weight loss surgery and an associated program can provide a plan and structure to help you succeed — if you can manage your surroundings and keep a healthy mindset.

What are the different weight loss surgery options?

Houston Methodist’s board-certified bariatric surgeons have decades of experience and use the most advanced minimally invasive weight loss surgery procedures available.


You and your weight loss surgeons will work together to determine the type of weight loss surgery that is best for you. This typically is based on your:

  • BMI
  • Weight-related medical conditions
  • Future health goals 


The types of weight loss surgery procedures performed at Houston Methodist are:

Gastric Sleeve


Sleeve Gastrectomy Image


Also called a sleeve gastrectomy, the gastric sleeve is a minimally invasive surgical procedure that:

  • Promotes weight loss by permanently removing two-thirds of the stomach
  • Results in a feeling of fullness from smaller amounts of food
  • Preserves the stomach’s ability to slow the emptying process


A gastric sleeve procedure typically lasts about an hour and involves only five small incisions. Patients usually return to work or activities in about two weeks.

Gastric Bypass

Also called the Roux-en-Y gastric bypass, this minimally invasive surgical procedure promotes weight loss by:

  • Restricting food intake to a small, surgically created pouch divided from the rest of the stomach
  • Connecting the new food pouch directly to the middle of the small intestine — bypassing the upper small intestine, which reduces the amount of calories absorbed


A gastric bypass decreases hunger and increases the feeling of fullness. It also reduces absorption of some vitamins and nutrients.

Weight Loss Surgery Revisions

Revisions are typically performed because of a complication from a previous weight loss surgery (lap band, stomach stapling, gastric bypass or gastric sleeve). These complications include:

  • Ulcerations or strictures
  • Weight regain resulting from reverting to poor eating habits. The weight loss surgeon would either revise the existing technique or convert to another procedure.
  • An adjustable gastric band (lap band) that has eroded or slipped — or is preventing a person from tolerating solid food. The weight loss surgeon would remove the band and convert to a gastric sleeve or gastric bypass.
  • Severe gastroesophageal reflux disease (GERD) caused by a gastric sleeve that cannot be resolved with medication. The weight loss surgeon would convert the sleeve to a gastric bypass.

What are the risks associated with weight loss surgery?

Houston Methodist’s weight loss surgeons have extensive surgical experience and use the least invasive techniques available. However, as with any surgery, there are risks. Complications are rare and include (but are not limited to): leaks, ulcers, strictures, bowel obstructions and hernias.


If you have concerns or are experiencing urgent medical issues, please contact your surgeon’s office immediately.

Getting started

Candidates for weight loss surgery include those with a body mass index (BMI) of 40 or higher, or those with a BMI of at least 35 who also suffer from one or more weight-related medical conditions, such as diabetes, high blood pressure, heart disease or breathing problems.
