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.

Real-world scenarios

  • This often appears as unexpected fatigue that lasts for several weeks.
  • People may notice a yellow tint to their eyes during a physical.
  • This often appears as routine blood work showing elevated liver enzymes.
  • People may notice dark-colored urine despite drinking plenty of fluids.

Common vs serious explanations

Common
  • Seasonal flu or viral cold
  • General fatigue from lack of sleep
  • Mild food poisoning causing nausea
  • Temporary stress-related digestive upset

  • Liver failure or end-stage liver disease
