The main consequence of hepatitis B is the destruction of liver cells, replaced by scar tissue known as fibrosis. Depending on the amount of fibrosis, several stages can be distinguished, from F1 (mild fibrosis) to F4 (very high amount of fibrosis). From this stage onwards, we speak of cirrhosis of the liver. Painless signs of the disease include yellowing of the skin, fatigue and itching. More serious complications can occur, such as hemorrhage, edema of the lower limbs or liver cancer.
