When you have Hep C, it starts to damage the liver right away, even if you have no symptoms.
It begins by causing inflammation (swelling) of the liver. Over time, that causes scarring (fibrosis). When scarring progresses, it can become severe and block blood flow. At this point, it is called cirrhosis of the liver. Cirrhosis keeps the liver from working as it should, and may even cause permanent damage. The amount of damage in the liver is measured by a fibrosis score.
It’s important to keep in mind that the sooner Hep C is treated, the better the chances are for being cured.
