Description

Cirrhosis of the liver is a chronic and progressive condition characterized by the scarring and damage of liver tissue. It occurs when healthy liver cells are replaced by scar tissue, disrupting the normal structure and function of the liver. This scarring impairs the liver's ability to perform vital functions such as detoxification, metabolism, and nutrient storage. Causes of cirrhosis of liver Cirrhosis of the liver can be caused by various factors. Some of the most common causes include: Chronic alcohol abuse: Long-term and excessive alcohol consumption is a leading cause of cirrhosis. Alcohol damages liver cells over time, leading to inflammation and scarring. Viral hepatitis: Chronic infections with hepatitis B or hepatitis C viruses can cause liver inflammation and ultimately lead to cirrhosis if left untreated. These viral infections are commonly transmitted through contaminated blood or body fluids. Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH): NAFLD is a condition characterized by the accumulation of fat in the liver, often associated with obesity and metabolic disorders such as diabetes. If the fat buildup progresses and causes inflammation and liver cell damage, it can develop into NASH, which can eventually lead to cirrhosis. Autoimmune hepatitis: In autoimmune hepatitis, the body's immune system mistakenly attacks and damages liver cells, leading to chronic inflammation. Over time, this can result in cirrhosis. Chronic viral infections: Besides hepatitis B and C, other chronic viral infections like hepatitis D and hepatitis E can also contribute to the development of cirrhosis. Genetic and metabolic disorders: Certain inherited conditions, such as Wilson's disease, hemochromatosis (excessive iron buildup), and alpha-1 antitrypsin deficiency (lack of a protein that protects the liver), can cause liver damage and cirrhosis. Medications and toxins: Prolonged exposure to certain medications, toxins, or chemicals can lead to liver damage and cirrhosis. Examples include long-term use of high-dose acetaminophen, methotrexate, and exposure to industrial chemicals. It's important to note that cirrhosis can also result from multiple factors combined or from unknown causes (cryptogenic cirrhosis). Early detection and management of the underlying cause are crucial in preventing or slowing down the progression of cirrhosis Symptoms of cirrhosis of liver Cirrhosis of the liver can initially be asymptomatic, meaning that there may be no noticeable symptoms in the early stages. However, as the disease progresses, the following symptoms may occur: Fatigue and weakness: Persistent tiredness and a lack of energy are common symptoms of cirrhosis. Jaundice: Yellowing of the skin and eyes due to the buildup of bilirubin, a yellow pigment, in the body. It occurs when the liver is unable to effectively process and eliminate bilirubin. Abdominal swelling: Cirrhosis can lead to fluid accumulation in the abdomen, resulting in abdominal swelling or bloating, a condition known as ascites. Loss of appetite and weight loss: Individuals with cirrhosis may experience a reduced appetite and unintentional weight loss. Nausea and vomiting: Liver dysfunction can lead to digestive problems, including nausea, vomiting, and a general feeling of discomfort in the upper abdomen. Easy bruising and bleeding: The liver produces blood clotting factors, and their impairment in cirrhosis can result in easy bruising, bleeding gums, and frequent nosebleeds. Itchy skin: The accumulation of bile salts due to impaired liver function can cause itching or pruritus. Changes in mental function: Advanced cirrhosis can lead to hepatic encephalopathy, resulting in confusion, forgetfulness, personality changes, and even coma in severe cases. Spider angiomas: These are small, spider-like blood vessels that become visible on the skin due to increased estrogen levels and altered blood flow in cirrhosis. Dark urine and pale stools: The liver plays a role in processing waste products, and when it is not functioning properly, urine may become darker, while stools may appear pale or clay-colored.
