Ask the Expert: Why Liver Health Matters on Your Bariatric Journey

Bariatric surgery has become an important tool in the fight against obesity, helping many patients improve their health and quality of life. But the journey doesn’t end after surgery. One of the lesser-known but serious concerns is the risk of liver disease, particularly non-alcoholic fatty liver disease (NAFLD), which often goes undetected in obese patients both before and after bariatric procedures.

As a physician, I see how closely obesity and liver health are connected. NAFLD affects about 1 in 4 adults in the U.S. and can progress to non-alcoholic steatohepatitis (NASH), which involves inflammation and potential liver damage. In patients with obesity, insulin resistance leads to fat buildup in the liver—an issue present in up to 70% of these individuals. That’s why it’s critical to assess liver health early and often.

Bariatric surgery doesn’t just support weight loss—it can also improve liver function. Research shows that many patients with NAFLD see significant improvement after surgery. One study found nearly 90% of patients had better liver outcomes following weight loss. Still, success depends on several factors: the patient’s starting liver health, the type of procedure, and how well they stick to post-op lifestyle changes.

At our center, we focus heavily on routine monitoring. This includes liver function tests, imaging, and sometimes biopsies if needed. We also stress the importance of long-term follow-up. Regular checkups allow us to catch any issues early and offer timely interventions.

Ultimately, bariatric surgery is a powerful step toward better health, but it’s not a cure-all—especially for liver disease. Ongoing monitoring and lifestyle commitment are key. At DHR Health Bariatric and Metabolic Institute, I’m currently leading a research initiative to explore how weight loss surgery impacts liver health long-term. Our team is collaborating with global experts to develop new guidelines for early detection and ongoing monitoring of fatty liver disease in this patient population.

By staying informed and proactive, both patients and providers can work together to protect liver health and achieve lasting results after bariatric surgery.
