Alcoholic liver disease (ALD) can be diagnosed through a combination of medical history, physical examination, blood tests, imaging tests, and liver biopsy.

The diagnosis of ALD typically involves taking a detailed medical history to assess the extent of alcohol use and the duration of drinking. A physical exam may reveal symptoms such as jaundice (yellowing of the skin and eyes), abdominal swelling, and liver tenderness. Blood tests can reveal abnormal liver enzymes, low platelet count, and elevated bilirubin levels.

Imaging tests such as ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI) may be used to detect signs of liver damage and to assess the extent of the damage. Liver biopsy may also be performed to confirm the diagnosis and assess the severity of the disease.

It is important to note that ALD can progress to end-stage liver disease, which may require a liver transplant. Therefore, early diagnosis and treatment are crucial in managing the disease and preventing further damage to the liver.
