When HIV infects the body, diarrhea can occur, but it can also occur without it at all. When the AIDS stage is reached, there are symptoms of immunodeficiency and a variety of infections can occur. Diarrhea may occur if the infection is more severe and causes digestive disorders, or it may occur as a direct result of an infection of the digestive tract. In the 2-4 weeks just after the HIV infection, there may be some flu-like symptoms due to a large number of HIV replications, resulting in viremia, and diarrhea, or diarrhea, may appear among these symptoms. Therefore, if you have had unprotected sex with a stranger, shared syringes, or had a tattoo, eyebrow tattoo, or tooth extraction in an unclean place, you may have contracted HIV in the previous 2-4 weeks. If you have diarrhea, fever, rash, sore throat and swollen lymph nodes, you may be considered to be infected with HIV and may be tested for HIV. However, if there is no such behavior before, simply because of diarrhea, there is no need to suspect that you are infected with HIV.
