Liver cirrhosis is a serious, irreversible condition in which healthy liver tissue is replaced with scar tissue, caused by long-term damage to the liver. It is a progressive disease that can be caused by a variety of factors, including viral infections, alcohol abuse, or fatty liver disease. The most common symptoms of cirrhosis include fatigue, weight loss, jaundice, and abdominal pain. The liver is responsible for filtering and detoxifying the blood, and when scar tissue replaces healthy liver tissue, it can become too damaged to perform its vital functions. This can lead to a build-up of toxins in the blood, and can cause serious health problems such as internal bleeding, fluid accumulation, and liver failure. Diagnosis of cirrhosis is typically made through a physical exam, blood tests, and imaging tests such as ultrasound or CT scan. Treatment may include lifestyle changes such as cutting back on alcohol and avoiding certain medications, and in more serious cases, a liver transplant may be necessary. Prevention of cirrhosis is key, and includes avoiding excessive alcohol consumption, staying up-to-date on vaccinations, and maintaining a healthy weight. Early diagnosis and treatment is also important, as it can help slow the progression of the disease. If you have any of the symptoms of cirrhosis or suspect you may be at risk, it is important to talk to your doctor.
