Hepatitis C
Hepatitis C is a viral infection that causes liver inflammation, which can lead to serious liver damage if left untreated. It is primarily spread through contact with the blood of an infected person.
Overview
Hepatitis C is a viral infection that causes liver inflammation, which can lead to serious liver damage if left untreated. It is primarily spread through contact with the blood of an infected person.
Understand this condition
The Hepatitis C virus attacks the liver cells, causing the body's immune system to trigger inflammation. Over time, this constant inflammation leads to the formation of scar tissue, replacing healthy liver cells. When too much scar tissue forms, the liver can no longer filter toxins or process nutrients properly.
Why it happens
The virus enters the bloodstream and targets hepatocytes, the primary cells of the liver. It replicates rapidly, and the immune response against the virus causes collateral damage to liver tissue. If the body cannot clear the virus within six months, the infection becomes chronic and slowly progresses.
