What Are Immune Deficiencies? When the Body’s Defenses Fall Short
Immune deficiencies occur when the body’s immune system is unable to mount an adequate defense against pathogens such as viruses, bacteria, and fungi. These conditions can be either inherited (primary immunodeficiency) or acquired later in life (secondary immunodeficiency) and often leave individuals vulnerable to frequent, prolonged, or severe infections.
Primary immune deficiencies are typically genetic and can manifest in childhood or early adulthood. Examples include Common Variable Immune Deficiency (CVID), Severe Combined Immunodeficiency (SCID), and Selective IgA Deficiency. Secondary immune deficiencies may result from factors like chemotherapy, certain medications (e.g., corticosteroids), HIV infection, malnutrition, or chronic diseases such as diabetes or cancer.
While some immune deficiencies are mild and manageable, others can be life-threatening. Fortunately, advances in immunology and clinical research are opening new doors for better diagnosis, treatment, and long-term health management.
Symptoms of Immune Disorders
Immune disorders present with a wide range of symptoms depending on whether the immune system is overactive or weakened. Some symptoms may be episodic, while others are persistent or progressive.
Common Autoimmune Symptoms:
- Fatigue or chronic tiredness
- Joint pain, stiffness, or swelling
- Skin rashes or changes
- Digestive issues (diarrhea, bloating, cramping)
- Fever or inflammation without infection
- Numbness or tingling in hands and feet
- Unexplained weight changes
Common Immunodeficiency Symptoms:
- Frequent infections (sinus, respiratory, ear, etc.)
- Slow recovery from illness
- Chronic cough or diarrhea
- Poor wound healing
- Recurrent fevers
Early diagnosis and treatment can help reduce long-term damage and improve quality of life.
