NAFLD stands for Non-Alcoholic Fatty Liver Disease. The first stage of NAFLD is often referred to as simple steatosis, which is the excessive accumulation of fat in the liver cells. Simple steatosis is a reversible condition, and if addressed early, can be reversed with lifestyle modifications such as diet and exercise. However, if left untreated, it can progress to more serious stages of NAFLD, including non-alcoholic steatohepatitis (NASH) and cirrhosis.
Signs and Symptoms
In the early stages of NAFLD, there are usually no signs or symptoms. As the condition progresses, individuals may experience fatigue, weakness, abdominal pain, weight loss, and a feeling of fullness in the upper abdomen. In some cases, the liver may become enlarged. As the disease progresses, additional symptoms can include jaundice, increased bleeding, and even liver failure.
Diagnosis
NAFLD is diagnosed through a physical exam and laboratory tests. The doctor may order blood tests to measure liver enzymes and other substances, such as cholesterol, triglycerides, and glucose. Imaging tests, such as an ultrasound, CT scan, or MRI, can also be used to diagnose the condition.
Treatment
The primary goal of treatment for NAFLD is to reduce fat in the liver by making lifestyle changes, such as eating a healthy, low-fat diet, increasing physical activity, and avoiding alcohol. In some cases, medications may also be prescribed to help reduce fat in the liver. If the condition progresses to a more serious stage, a liver transplant may be recommended.
