Weight Loss Surgery: Who Is The Best Candidate?


Weight loss surgery, also known as bariatric surgery, is medical procedures designed to help individuals who are severely obese achieve significant and sustainable weight loss. While it can be a powerful tool for improving health and quality of life, not everyone is a candidate for weight loss surgery. Determining the best candidates involves careful assessment by healthcare professionals. Here’s a closer look at who might be considered the best candidate for weight loss surgery.

BMI criteria:

Body Mass Index (BMI) is often used as a primary criterion to determine eligibility for weight loss surgery. The specific BMI thresholds may vary by surgery type and healthcare guidelines, but generally, candidates are considered when:

  • BMI is 40 or higher (severe obesity).
  • BMI is 35 or higher with obesity-related health conditions like type 2 diabetes or high blood pressure.

Failed non-surgical approaches:

Candidates for weight loss surgery have typically tried and failed to achieve significant and sustainable weight loss through non-surgical methods such as diet and exercise. The decision for surgery often comes after a documented history of unsuccessful attempts at weight loss.

Commitment to lifestyle changes:

Successful weight loss surgery requires a long-term commitment to lifestyle changes. Candidates must be willing to make dietary adjustments, engage in regular physical activity, and follow post-operative guidelines for the rest of their lives.

Psychological evaluation:

A psychological evaluation is a crucial step in the assessment process. It helps identify any underlying mental health issues, emotional factors, or eating disorders that might affect a candidate’s ability to adhere to the post-surgery regimen.


Candidates with obesity-related health conditions, such as type 2 diabetes, sleep apnea, high blood pressure, or joint problems, may be considered suitable candidates for weight loss surgery. In many cases, surgery can lead to improvements or even remission of these conditions.

Age and health status:

Age and overall health status are important considerations. Candidates should generally be between 18 and 65 years old, although some exceptions may apply. They should also be in relatively good health to undergo surgery safely.

It’s crucial to note that the decision to undergo weight loss surgery should be made in consultation with a healthcare provider, preferably a bariatric surgeon, who can assess an individual’s specific situation and needs.
