You may not have anticipated the changes you had to make after bariatric surgery, which could lead to altered emotions and elevated levels of stress. Here’s why patients may be at a higher risk for substance use following bariatric surgery.

Is there a correlation between bariatric surgery and substance abuse?

On average, 19% of patients had significant alcohol use prior to bariatric surgery. In the same study, researchers found 23% of patients had significant alcohol use after bariatric surgery. Is there a correlation between the two? This study suggests there is , with odds increasing around one year after your weight loss surgery. Since diet is restricted for the first 6-12 months, substance abuse is usually not seen in patients until 1-2 years post-surgery.

Following bariatric surgery, you are required to make life changes that could affect your mood and how you see your body.

Psychological Risk Factors for Substance Abusive After Weight Loss Surgery

Do you know if you may be at a higher risk for substance abuse after weight loss surgery?

  • History of Substance Abuse
  • Cigarette Smoking
  • Regular Alcohol Use
  • Recreational Drug Use

Why do we see this correlation?

It is common for patients to trade one addiction for another if they were previously addicted to food and now must follow a stricter diet. Many patients describe it as a “break up” with food. It is not uncommon for you to feel increased emotions during this period. Know you are not alone in this struggle. There are many resources available like support groups hosted by your hospital or individual mental health counseling. Seek out help from your surgical team if you have any questions or need a referral.

How to Reduce Your Chances of Substance Use

You might get extra skin folds or feel uncomfortable about how your body looks. It can be difficult to adapt to your new diet, as you cannot eat the same foods anymore. Be sure to talk to your doctor about any of the changes you have questions about. Discuss with your doctor any previous experiences with substance use.
