Introduction :
Grade 1 fatty liver , also known as simple hepatic steatosis, is the earliest and mildest stage of non-alcoholic fatty liver disease (NAFLD).
At this stage, fat begins to accumulate within the liver cells, but there is little to no inflammation or liver damage. Many people with Grade 1 fatty liver are unaware of the condition due to its subtle or absent symptoms.
What Is Grade 1 Fatty Liver?
Fatty liver occurs when excess fat builds up in the liver. Normally, the liver contains a small amount of fat, but when fat accounts for more than 5-10% of the liver’s weight, it is considered a fatty liver. Grade 1 indicates the least severe form, where fat is present, but liver function is still largely preserved.
Symptoms of Grade 1 Fatty Liver :
In many cases, Grade 1 fatty liver is asymptomatic, especially in the early stages. However, some individuals may experience mild, nonspecific symptoms due to the liver’s altered metabolism and fat accumulation.
1. General Fatigue
One of the most common symptoms is persistent tiredness or low energy levels. This occurs as the liver’s ability to filter toxins and regulate energy production is slightly impaired.
2. Discomfort in the Upper Right Abdomen
Some individuals may feel a dull ache or fullness in the upper right side of the abdomen, where the liver is located. This is due to the enlargement of the liver (hepatomegaly) caused by fat deposition.
3. Mild Digestive Disturbances
fatty liver may contribute to:
- Indigestion
- Bloating
- Gas
- Mild nausea, especially after fatty meals
These symptoms result from the liver’s decreased efficiency in producing bile and enzymes essential for digestion.
4. Unexplained Weight Gain or Difficulty Losing Weight
Fatty liver often correlates with metabolic changes, leading to central obesity and difficulty shedding weight, even with dietary efforts.
5. Mild Jaundice (Rare)
Although uncommon at this stage, very mild yellowing of the skin or eyes may occur in some cases, especially if the liver’s detoxifying capacity starts to decline.
6. Slight Elevation in Liver Enzymes
While not a symptom felt by the patient, blood tests may show a mild increase in liver enzymes such as ALT (alanine aminotransferase) and AST (aspartate aminotransferase), indicating liver cell stress or injury.
Who Is at Risk?
Certain individuals are more prone to developing Grade 1 fatty liver:
- People with obesity or overweight
- Those with type 2 diabetes or insulin resistance
- Individuals with high cholesterol or triglycerides
- Those who consume a high-fat, high-sugar diet
- People with sedentary lifestyles
- Individuals with polycystic ovary syndrome (PCOS) or metabolic syndrome
Diagnosis :
Since symptoms are often vague or absent, Grade 1 fatty liver is typically discovered during:
- Routine ultrasound imaging
- Health check-ups for elevated liver enzymes
- Fatty liver screening in high-risk individuals
Ultrasound is the most common, non-invasive method to detect fatty changes in the liver.
Take away message :
Fatty liver is an early warning sign of liver fat accumulation. While symptoms are often minimal, subtle signs such as fatigue, abdominal discomfort, and digestive issues may occur. Recognizing these early symptoms is crucial for taking timely action through lifestyle changes, dietary adjustments, and regular monitoring to prevent progression to more severe liver conditions.
