Fatty Liver: Difference Between Grade 1 and Grade 2 Explained
Today’s lifestyle – less exercise, junk food, and long hours of sitting – is causing many health problems. One of the fastest growing issues is fatty liver. When extra fat starts collecting in the liver cells, the condition is called fatty liver disease. Doctors classify this condition into different fatty liver disease stages. Among these, the most common are Grade 1 fatty liver (early stage) and Grade 2 fatty liver (moderate stage). The good news is that if fatty liver is detected early, it can be controlled and even reversed. With expert inputs from Dr. Sarang Barbind at Leela Superspeciality Hospital, let us understand the difference between Grade 1 and Grade 2 fatty liver and how they can be managed.
Understanding Fatty Liver: What Are Grade 1 & Grade 2:
What is Fatty Liver?
Fatty liver, also called hepatic steatosis, happens when more than 5–10% of the liver’s weight is made up of fat. This condition may develop due to excess alcohol intake (alcoholic fatty liver disease) or because of lifestyle-related problems like obesity, diabetes, and poor diet (non-alcoholic fatty liver disease).
Grade 1 Fatty Liver:
Grade 1 fatty liver is considered the mildest stage of the disease. At this level, a small amount of fat gets deposited in the liver cells, but it does not cause any major inflammation or damage. Most people with Grade 1 fatty liver do not show symptoms. It is often found accidentally during a routine ultrasound or blood test. The good news is that this stage can be reversed with lifestyle changes.
Symptoms of Fatty Liver (Grade 1):
- Usually no clear symptoms.
- Most people don’t even know they have it until an ultrasound or blood test shows fat deposits in the liver.
- Sometimes mild tiredness or slight heaviness in the abdomen may occur, but it’s rare.
Grade 2 Fatty Liver:
Grade 2 fatty liver is a more advanced stage than Grade 1. Here, a larger amount of fat builds up inside the liver, which raises the chances of inflammation and damage to liver cells. Some patients may start noticing tiredness, bloating, or mild discomfort on the right side of the upper abdomen. If left untreated, Grade 2 fatty liver may progress further and can lead to serious conditions such as fibrosis or cirrhosis.
Symptoms of Fatty Liver (Grade 2):
- Grade 2 Fatty Liver:
- Symptoms may start appearing because the fat buildup is more significant.
- Common signs:
- Persistent tiredness and low energy
- Bloating or indigestion
- Mild pain or discomfort in the upper right side of the abdomen
- Unexplained weight gain or difficulty losing weight
These are not always severe, but they are warning signs that the liver is struggling.
Grade 1 vs Grade 2 Fatty Liver: Key Differences:
Conclusion:
The main difference between Grade 1 fatty liver and Grade 2 fatty liver is the amount of fat in the liver and the level of risk. Grade 1 fatty liver is an early stage. It is mild, has no clear symptoms, and can be reversed with good habits. Grade 2 fatty liver is a moderate stage. It has more fat, may cause tiredness or stomach discomfort, and can become serious if not treated on time. The best part is both stages can be controlled and improved if you take action early. As Dr. Sarang Barbind from Leela Superspeciality Hospital advises, simple lifestyle changes like healthy diet, exercise, and regular check-ups can protect your liver.
