What happened

Dan Marino, the Miami Dolphins legend, said he was diagnosed with liver disease in 2007. He named the condition MASH, a form of fatty liver disease. His comments were published on September 16, 2025, in coverage citing a People interview.

Marino said doctors told him the condition could be reversed. He described changes in eating and daily exercise that have helped him manage it. He also said he cut back on wine, pizza, candy, and ice cream.

What is MASH

MASH stands for metabolic dysfunction associated steatohepatitis. It is linked to fat build up in the liver and chronic inflammation. If left untreated, it can lead to cirrhosis or liver cancer. Reporters cited Cleveland Clinic guidance to explain the risks.

CBS Sports also summarized the diagnosis and noted Marino is 64. It cited his People interview, which framed the news around lifestyle changes and stability on recent scans.

UPI’s write-up echoed that message. It reported Marino expects his prognosis to keep improving as he stays active and keeps to his plan.

Why Marino’s voice matters

Marino is one of the most famous quarterbacks ever. He was the first to throw 5,000 yards in a season in 1984. He retired after 1999 and entered the Pro Football Hall of Fame in 2005. A high profile figure speaking about MASH can push people to get checked.

Key quotes and details

Marino said doctors told him his condition “can be reversible.” He said he now trains and eats with more care. Reports describe a shift toward a Mediterranean pattern, and less sugar and alcohol. These are common steps doctors use for fatty liver disease.

CBS Sports noted he framed the update as good news. He is doing well after changes in diet and training. UPI added that ultrasounds show stability, and he aims to keep the trend going.

How it affects readers

Marino’s story is a reminder that MASH can be quiet for years. Many people have few or no symptoms. Routine labs or scans may spot it first. Reporters noted medical sources that tie MASH to weight, blood sugar, and cholesterol. Screening and lifestyle steps can help./\eh

If you have questions about liver health, talk with a clinician. News reports cannot replace care from your own doctor.

What happens next

Expect more public focus on MASH this week as the NFL season ramps up. Media coverage will likely continue to reference Marino’s interview and the role of diet and exercise in care. Marino also continues as a Dolphins icon and front office presence, so local interest will stay high.
