Complications of HIV
What is HIV?
Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system, especially the CD4 cells, which help fight infections. Without treatment, HIV can weaken the immune system and lead to serious health problems.
With early diagnosis and proper treatment, many people with HIV live long, healthy lives.
Why Can HIV Cause Complications?
When HIV is not well controlled, the immune system becomes weaker. This makes the body less able to fight infections and certain cancers. These problems are called complications of HIV.
Common Complications of HIV
1. Infections (Opportunistic Infections)
These infections occur more often or are more severe because the immune system is weakened.
Examples include:
Tuberculosis (TB)
Pneumonia
Oral or genital thrush (fungal infection)
Toxoplasmosis (brain infection)
Chronic diarrhea from intestinal infections
Symptoms may include:
Fever
Weight loss
Night sweats
Persistent cough
Chronic diarrhea

3. Neurological (Brain and Nerve) Problems
HIV can affect the brain and nervous system, leading to:
Memory or concentration problems

Depression or mood changes
Numbness or tingling in hands and feet
4. Heart, Kidney, and Liver Disease
Long-term HIV infection or some medications may increase the risk of:
Heart disease
Kidney damage
Liver disease (especially in people with hepatitis B or C)

Severe weight loss
Muscle weakness
Fatigue
How Can Complications Be Prevented?
The most effective way to prevent complications is:

Getting recommended vaccinations
Eating a healthy diet
Avoiding smoking, excessive alcohol, and drug use
