Non-alcoholic fatty liver disease (NAFLD) is a condition that occurs when there is an excessive buildup of fat in the liver, which is not caused by alcohol consumption.
It is becoming increasingly common and is now the most common cause of chronic liver disease in the United States, affecting around 80-100 million Americans.
What is NAFLD?
NAFLD is a condition in which fat builds up in the liver cells. It is not caused by consuming alcohol and is often associated with obesity, insulin resistance, and metabolic syndrome.
NAFLD can range from simple fatty liver, which is when there is only an accumulation of fat in the liver cells, to more severe forms such as non-alcoholic steatohepatitis (NASH), fibrosis, and even liver cirrhosis.
What are the Symptoms of NAFLD?
Most people with NAFLD do not experience any symptoms, and the condition is usually detected during routine blood tests or imaging studies. However, some people may experience fatigue, abdominal discomfort, and weakness.
What Causes NAFLD?
The exact cause of NAFLD is unknown, but it is associated with a variety of risk factors, including:.
- Obesity
- Insulin resistance
- Metabolic syndrome
- Type 2 diabetes
- Sedentary lifestyle
- High-fat diet
- Elevated cholesterol
- High blood pressure
How is NAFLD Diagnosed?
NAFLD is usually diagnosed through blood tests, imaging studies, and liver biopsies. Blood tests can show elevated levels of liver enzymes, and imaging studies like ultrasound, CT scans, and MRIs can show the presence of fat in the liver.
A liver biopsy is the most accurate way to diagnose NAFLD, and it can also help determine the severity of the disease.

How is NAFLD Treated?
The treatment of NAFLD primarily involves lifestyle modifications. People with NAFLD should strive to maintain a healthy weight, follow a healthy diet, exercise regularly, and avoid alcohol and other substances that can damage the liver.
In some cases, medication may be prescribed to treat underlying conditions such as diabetes or elevated cholesterol levels. In severe cases of NAFLD, liver transplantation may be necessary.
Preventing NAFLD
There are several things people can do to reduce their risk of developing NAFLD, including:.
- Maintain a healthy weight
- Follow a healthy diet low in saturated and trans fats
- Exercise regularly
- Avoid alcohol and drugs
- Manage underlying conditions such as diabetes and high blood pressure
The Link Between NAFLD and COVID-19
NAFLD has emerged as a potential risk factor for severe COVID-19. Studies have shown that people with NAFLD are more likely to experience severe illness and hospitalization from COVID-19 compared to those without the condition.
This is thought to be due to the underlying inflammation and metabolic dysfunction that occurs with NAFLD, which can weaken the body’s immune response to infection.
Conclusion
