Fatty liver disease is a growing health concern across the world. It happens when too much fat builds up in the liver. While a small amount of fat in the liver is normal, when it reaches higher levels, it can cause inflammation, damage, and serious long-term problems.

There are two main types of fatty liver: 

• Alcoholic fatty liver disease (AFLD) – caused by heavy alcohol use.


• Non-alcoholic fatty liver disease (NAFLD) – happens in people who drink little or no alcohol, often due to poor diet, obesity, diabetes, or high cholesterol.

The Four Stages of Fatty Liver:Fatty liver develops in stages:

• Simple fatty liver (Steatosis): Fat accumulates in liver cells, but there is no inflammation or damage yet. It often goes unnoticed.


• Non-alcoholic steatohepatitis (NASH): The liver becomes inflamed and starts to get damaged. This stage can lead to permanent harm if not treated.


• Fibrosis: Long-term inflammation causes scarring (fibrosis) in the liver, but there’s still some healthy tissue.


• Cirrhosis: Severe scarring takes over. The liver starts to fail and may lead to complications like liver cancer, internal bleeding, and even death. 

How Do You Know If You Have Fatty Liver?

The tricky part is that fatty liver often shows no symptoms in the early stages. Many people live with it for years without knowing.

• Some people may experience:


• Constant tiredness or fatigue


• Discomfort or pain in the upper right side of the abdomen


• Unexplained weight loss


• Yellowing of the skin or eyes (in advanced stages)

Most of the time, fatty liver is discovered during routine blood tests, especially if liver enzymes (like SGPT/ALT) are raised. Your doctor may then recommend:

• Ultrasound of the abdomen – a painless test that shows fat in the liver


• FibroScan or liver elastography – a special scan that measures scarring in the liver


• Liver function tests – to check how well the liver is working


• Sometimes, a liver biopsy may be needed in complex cases

When Should You Be Concerned? You should talk to your doctor if you:

• Have risk factors like obesity, diabetes, high cholesterol, or high blood pressure


• Drink alcohol regularly


• Are always tired without a clear reason


• Have abnormal liver test results

 Early detection is key—because fatty liver is reversible in its early stages.

How Can You Manage or Reverse Fatty Liver?

The good news is that lifestyle changes can make a big difference: 

• Lose weight (even 5–10% of body weight can improve liver health)


• Eat a balanced diet with more vegetables, fruits, whole grains, and less sugar and fat


• Exercise regularly – aim for 30 minutes a day, 5 days a week


• Avoid alcohol completely, especially if you have fatty liver


• Manage diabetes, cholesterol, and blood pressure properly 

Takeaway

Your liver silently supports your body every day. Fatty liver might not cause symptoms at first, but ignoring it can lead to life-threatening problems. A simple check-up can catch it early—and with the right lifestyle, your liver can heal itself. 

Listen to your liver before it shouts. Prevention is always better than cure.
