Because HIV weakens the immune system, it makes an infected person very susceptible to various opportunistic disease, cancers, and viruses that take advantage of weakened immunity.
Antiretroviral drugs used to treat HIV can also cause serious medical complications, such as abnormal fat distribution, abnormal lipid and glucose metabolism, and bone loss.
is the most common opportunistic infection associated with HIV. For people with
healthy immune systems, tuberculosis does not cause as great a danger as those
suffering from a weakened immune system. TB affects the lungs or central
nervous system and travels through the air, making it very easy to contract.

Salmonellosis (also known as salmonella food poisoning) is a bacterial infection contracted through contaminated food
or water, causing diarrhea, fever, abdominal pain, vomiting, and chills.

Cytomegalovirus (CMV) is a
herpes virus transmitted through saliva, blood, urine, semen, and breast milk.
In a healthy person, CMV can remain dormant, but in a person with a weakened
immune system, CMV can cause damage to the eyes, digestive tract, lungs, or
other organs. It is a highly feared HIV-associated infection because it can

Also known as “thrush,” this infection can affect the mouth and throat or
vagina, causing inflammation and a thick white coating on mucous membranes. This
infection can also get into the bloodstream and be very dangerous to people

This parasitic infection is often spread through cats or contaminated water
or meat. A person with a healthy immune system can keep the parasite from
causing illness. However, in the case of a compromised immune system, toxoplasmosis
can cause brain defects, blindness, and damage to the central nervous system.

HIV weakens the immune system, making a patient vulnerable to certain cancers. It is important to detect early signs of cancers, before they progress too far to be treated and produce untreatable negative effects on the body. The most common AIDS-related cancers include:
Kaposi’s sarcoma is most commonly associated with people infected by HIV.
It is a tumor of the blood vessel walls, which usually manifests as pink, red,
or purple lesions on the skin and mouth. These tumors may also infect a person
internally on the digestive tract or lungs. It is believed to be caused by a
virus known as HHV-8.

This cancer, originating in the white blood cells, usually begins in the
lymph nodes, causing swelling in an infected neck, armpit, or groin.

Wasting syndrome is marked by unintended weight loss (of at least 10 percent)
and accompanied by diarrhea, chronic weakness, and fever.
HIV can cause indirect damage to the nerve cells, causing confusion, forgetfulness, depression, anxiety, and trouble walking. Many HIV sufferers develop dementia, which can inhibit mental function.
