Abnormalities in the Immune System

Abnormalities in the immune system occur when it doesn’t work properly. Sometimes it overreacts, causing allergies or autoimmune diseases where the body attacks itself. Other times, it underreacts, making individuals more vulnerable to infections. These issues can result from genetic factors, infections, or environmental influences. Immune system abnormalities can lead to chronic illnesses, repeated infections, or severe conditions like cancer. Understanding these problems helps in diagnosing and treating various health conditions effectively.
