—your "internal security system" isn't operating at full strength. Here is a breakdown of what low IgG means, why it happens, and what comes next. What is Immunoglobulin G (IgG)? IgG is your body's long-term memory for immunity. Once you’ve been exposed to a germ or a vaccine, your immune system creates IgG antibodies to recognize and fight that specific invader if it ever returns. Having adequate IgG levels is what prevents you from getting the same illness over and over again. Common Symptoms of Low IgG Many people with slightly low IgG may not notice any symptoms. However, if levels are significantly low, you might experience: Recurrent Infections: Frequent bouts of bronchitis, pneumonia, or sinus infections. Persistent Colds: Catching every "bug" that goes around and taking longer than usual to recover. Digestive Issues: Chronic diarrhea or other gastrointestinal problems. Why Are My Levels Low? Low IgG isn't a disease itself, but rather a sign that something is affecting antibody production. Causes can be categorized into two groups: Primary Immunodeficiency: Genetic conditions you are born with that prevent the body from making enough antibodies (e.g., CVID). Secondary Causes: External factors that lower IgG over time, such as: Certain medications (like chemotherapy or immunosuppressants). Chronic conditions like kidney disease or protein-losing enteropathy. Specific types of blood cancers (like leukemia or lymphoma). Next Steps and Management Finding a low IgG result is the first step toward feeling better. Your doctor will likely: Perform Follow-up Tests: To see if other antibodies (IgA or IgM) are also affected. Monitor Symptoms: To determine if the low levels are actually impacting your health. Consider Treatment: For severe cases,

La bajada de IgG es consecuencia de otra condición o factor externo: —your "internal security system" isn't operating at full
Un nivel bajo de IgG indica que el sistema inmunológico no está produciendo suficientes anticuerpos para combatir infecciones de manera efectiva. Esto puede dejar al cuerpo vulnerable a enfermedades recurrentes. IgG is your body's long-term memory for immunity
