It is due to extra connections forming between the portal system and the paraumbilical veins. Other nonspecific signs
Some signs that may be present include changes in the nails (such as Muehrckes lines, Terrys nails, and nail clubbing). Additional changes may be seen in the hands (Dupuytrens contracture) as well as the skin/bones (hypertrophic osteoarthropathy). Advanced disease
As the disease progresses, complications may develop. In some people, these may be the first signs of the disease. Bruising and bleeding can result from decreased production of clotting factors
Hepatic encephalopathy (HE) occurs when ammonia and related substances build up in the blood. This build-up affects brain function when they are not cleared from the blood by the liver. Symptoms can include unresponsiveness, forgetfulness, trouble concentrating, changes in sleep habits, or psychosis. One classic physical examination finding is asterixis. This is the asynchronous flapping of outstretched, dorsiflexed hands. Fetor hepaticus is a musty breath odor resulting from increased dimethyl sulfide and is a feature of HE. Sensitivity to medication can be caused by decreased metabolism of the active compounds
Acute kidney injury (particularly hepatorenal syndrome) 
Cachexia associated with muscle wasting and weakness

Causes
Cirrhosis has many possible causes, and more than one cause may be present. History taking is of importance in trying to determine the most likely cause. Globally, 57% of cirrhosis is attributable to either hepatitis B (30%) or hepatitis C (27%). Alcohol use disorder is another major cause, accounting for about 20-40% of the cases.
Prevention
Key prevention strategies for cirrhosis are population-wide interventions to reduce alcohol intake (through pricing strategies, public health campaigns, and personal counseling), programs to reduce the transmission of viral hepatitis, and screening of relatives of people with hereditary liver diseases.Little is known about factors affecting cirrhosis risk and progression. However, many studies have provided increasing evidence for the protective effects of coffee consumption against the progression of liver disease. These effects are more noticeable in liver disease that is associated with alcohol use disorder. Coffee has antioxidant and antifibrotic effects. Caffeine may not be the important component; polyphenols may be more important. Drinking two or more cups of coffee a day is associated with improvements in the liver enzymes ALT, AST, and GGT. Even in those with liver disease, coffee consumption can lower fibrosis and cirrhosis. Treatment
Generally, liver damage from cirrhosis cannot be reversed, but treatment can stop or delay further progression and reduce complications. A healthy diet is encouraged, as cirrhosis may be an energy-consuming process. A recommended diet consists of high-protein, high-fiber diet plus supplementation with branched-chain amino acids. Close follow-up is often necessary. Antibiotics are prescribed for infections, and various medications can help with itching. Laxatives, such as lactulose, decrease the risk of constipation. Carvedilol increases survival benefit for patients with cirrhosis and portal hypertension.Alcoholic cirrhosis caused by alcohol use disorder is treated by abstaining from alcohol.
