The symptoms of acquired immunodeficiency syndrome (AIDS) in men may vary depending on the particular stage of the disease. The early stage may be characterized by fever, swollen glands, sore throat and fatigue. The late stage may be characterized by vomiting, pneumonia and extreme tiredness, according to AIDS.gov.
AIDS is a condition that is caused by the human immunodeficiency virus (HIV), according to Healthline. The virus usually weakens the human immune system to the point where it can no longer defend the body against infections or opportunistic diseases. The virus can be transmitted from one person to another through unprotected sexual intercourse and infected blood transfusion.
At the early stages of the disease, an infected man may experience symptoms including painful sensations of the muscles and joints, headaches, general weakness and sore throat.
After the early stage, the patient is likely to go through the clinical latency stage. Here, the patient is likely to experience very mild symptoms related to the condition. In certain cases the patient will experience no symptoms at all. At this stage, the virus is living within the human body but does not reproduce rapidly, which is why it does not cause any observable symptoms.
The late stage of the disease is characterized by symptoms such as persistent diarrhea, depression, memory loss and profuse night sweats.
