Weakened immune systems can be congenital (present at birth) or acquired (developed later in life). Common causes include:
- Genetic Disorders: Conditions like SCID (Severe Combined Immunodeficiency) are inherited. - Chronic Diseases: Diseases such as HIV/AIDS, diabetes, and cancer can impair immune function. - Medications: Immunosuppressive drugs used in organ transplant patients or for treating autoimmune diseases can weaken the immune system. - Lifestyle Factors: Poor nutrition, lack of sleep, and high stress levels can also contribute to a weakened immune system.
