Patients with HIV often do not have obvious nausea or desire to vomit. When patients are newly infected with HIV, they often have flu-like symptoms, such as headache, fever, fatigue, sore throat, diarrhea, and swollen lymph nodes. The reason for this is directly related to the fact that the HIV virus in the patient’s body is replicating in large numbers and the lymphocytes are dropping sharply. Patients often do not experience significant nausea or desire to vomit at this time, but will have significant symptoms of not wanting to eat, but these symptoms can often slowly resolve without treatment within a month. By the time the patient enters the onset of AIDS, the patient will have a variety of opportunistic infections and tumors. At this time, the patient does not have obvious nausea or vomiting, but will have obvious symptoms such as fever, fatigue, and weight loss.
