Nonalcoholic fatty liver disease (NAFLD) is a condition in which fat builds up in the liver. It is the most common type of liver disease in the United States and affects up to one-third of American adults. NAFLD can lead to a more serious condition called nonalcoholic steatohepatitis (NASH), which can damage the liver and lead to cirrhosis, liver failure, and even death.
NAFLD is caused by a number of factors, including obesity, insulin resistance, and high cholesterol. The exact cause is unknown, but it is thought to be a combination of genetic and environmental factors.
NAFLD usually progresses slowly and does not cause any symptoms. However, as the disease progresses, you may experience fatigue, weight loss, and pain in the upper right side of your abdomen. In some cases, NAFLD can lead to NASH, which can cause symptoms such as yellowing of the skin and whites of the eyes (jaundice), dark urine, and itching. NASH can also lead to cirrhosis, in which the liver is permanently damaged and cannot function properly.
If you have NAFLD, it is important to see your doctor for regular checkups. You should also make lifestyle changes to reduce your risk of developing NASH, such as losing weight, eating a healthy diet, and exercising regularly. If you have NASH, you may need medication or surgery to prevent liver damage.
Nonalcoholic fatty liver disease is a growing problem in the United States. It is important to be aware of the risks and to make lifestyle changes to reduce your risk of developing this disease.
Nonalcoholic fatty liver disease (NAFLD) is a growing problem worldwide. In the United States, it is estimated that 30-40% of the population has NAFLD, and it is the most common chronic liver disease in children and adults. The exact cause of NAFLD is unknown, but it is strongly associated with obesity, insulin resistance, and type 2 diabetes.
NAFLD is a spectrum of diseases, ranging from simple fatty liver (steatosis) to nonalcoholic steatohepatitis (NASH), which can progress to fibrosis, cirrhosis, and liver failure. NASH is the most serious form of NAFLD and can lead to liver transplantation.
There are no specific treatments for NAFLD, but weight loss, exercise, and a healthy diet are thought to be helpful. In some cases, NASH can be treated with drugs that improve insulin resistance, such as metformin.
NAFLD is a serious disease that can progress to liver failure. If you are obese or have type 2 diabetes, it is important to talk to your doctor about your risk for NAFLD. Early diagnosis and treatment is the best way to prevent progression to more serious disease.
