Context:

Fatty liver disease is characterized by the accumulation of fat in the liver, leading to potential inflammation and liver damage. It is primarily divided into two types: Alcohol-associated liver disease (ALD) from prolonged alcohol consumption and metabolic dysfunction-associated steatotic liver disease (MASLD) linked to conditions like obesity and type 2 diabetes. Early stages often show no symptoms, but fatigue, weakness, and abdominal discomfort can occur as it progresses. If left untreated, it can advance to cirrhosis and liver failure, necessitating a liver transplant for survival. Children can also be affected due to rising obesity rates, presenting symptoms similar to adults, such as headaches and irritability, especially if the disease reaches advanced stages.

Dive Deeper:

• Fatty liver disease occurs when fat accumulates in the liver, potentially causing inflammation and damage. There are two main types: ALD due to heavy alcohol use and MASLD associated with metabolic conditions like obesity and type 2 diabetes.

• In early stages, the condition may be asymptomatic, but symptoms like fatigue, weakness, and abdominal discomfort can appear when fat constitutes more than 5% of liver weight without inflammation or damage.

• As the disease progresses, inflammation leads to fibrosis, where scar tissue forms as the liver tries to repair itself. This stage is associated with symptoms such as itchy skin, bloating, jaundice, and mood swings.

• End-stage liver disease, or liver failure, occurs when cirrhosis progresses, leading to symptoms like weight loss, muscle cramps, easy bruising, and severe liver dysfunction that often requires a transplant.

• Children can develop fatty liver disease due to the increasing prevalence of obesity. Up to 1 in 10 children aged 2-19 may have MASLD, with symptoms similar to adults, including fatigue and concentration difficulties.

• Diet plays a crucial role in the prevention and management of fatty liver disease. Avoiding foods high in saturated fats and simple sugars, such as fried foods and sugary drinks, can help mitigate the disease's progression.

• Diagnosing fatty liver disease can be challenging due to its symptom overlap with other conditions like hepatitis C and Wilson disease. Accurate diagnosis requires distinguishing it from these conditions and assessing if alcohol consumption is a factor.
