Nonalcoholic Steatohepatitis (NASH): Understanding a Serious Fatty Liver Disease

Nonalcoholic steatohepatitis (NASH) is a progressive liver condition that develops when fat buildup in the liver causes inflammation and cellular damage. It belongs to a broader group of liver disorders known as nonalcoholic fatty liver disease (NAFLD), which occurs in people who drink little or no alcohol.

NASH represents the more severe stage of fatty liver disease and can lead to long-term liver complications if not properly managed.

What Is NASH?

NASH occurs when excess fat accumulates in liver cells and triggers inflammation. Over time, this inflammation damages liver tissue and may result in fibrosis (scarring), cirrhosis, or even liver cancer in advanced cases.

Nutrigenomics Market: Is DNA-Guided Nutrition the Future of Preventive Health?

Consumer health priorities in 2026 are shifting from reactive treatment to proactive optimization, fueling expansion in the Nutrigenomics Market. Rather than following generic diet plans, individuals are increasingly seeking nutrition strategies tailored to their unique genetic profiles. Healthcare providers, wellness clinics, and direct-to-consumer testing companies are integrating genetic screening into routine health assessments to better understand how specific nutrients interact with individual metabolic pathways. This approach is gaining traction among people managing chronic conditions, athletes optimizing performance, and health-conscious consumers aiming to prevent disease before symptoms arise.
