If you have sifilis can devolopment hepatitis?

huh? are you asking if syphilis can turn into hepatitis? if so the answer's no. if you're asking if the two diseases are mutually exclusive(meaning you for some reason you couldn't have both at once) also no.

Syphilis is a separate disease from hepatitis. However, both are sexually transmitted diseases and you can get both from the same person.
no. Syphilis is a completely different disease to hepatitis. But if you got syphilis, then maybe you also got hepatitis. They can both be transmitted with unprotected sex.
Yes, syphilis can cause hepatitis. Hepatitis simply means inflammation of the liver. Hepatitis may be caused by bacteria, viral infection, parasitic infestation, alcohol, drugs, toxins, etc.

While one of the manifestations of secondary syphilis includes hepatitis, it is usually not severe.

In contrast, hepatitis is seen very frequently in congenital syphilis and is usually severe.
