IgG4 is a specific type of antibody, which is a protein produced by your immune system to help protect against infections. Think of antibodies as the body's security guards, always on patrol to spot and neutralise harmful invaders like bacteria and viruses. IgG4 is one of four subclasses of the IgG antibody and plays a unique role in regulating the immune system. It often acts as a "peacemaker," preventing the immune system from overreacting to certain stimuli. Measuring IgG4 levels in your blood can provide important insights into how your immune system is functioning. In some rare conditions, the body produces too much IgG4, leading to inflammation and potential damage in various organs like the pancreas, liver, or kidneys. By checking IgG4 levels, doctors can better understand what's happening inside your body and guide treatment to restore balance and health.
Testing IgG4 levels can be important if there are signs of an immune system disorder, unexplained inflammation, or symptoms affecting various organs without a clear cause. It helps in diagnosing conditions like IgG4-related disease, which can impact the pancreas, liver, kidneys, and other organs. Early detection through testing allows for appropriate treatment to reduce inflammation and prevent organ damage. For those with certain allergies or autoimmune conditions, measuring IgG4 can also provide valuable information about how the immune system is behaving.
Several factors can influence IgG4 levels. Certain medical conditions, such as IgG4-related disease, can cause elevated levels. This condition involves chronic inflammation and can affect various organs, leading to symptoms like swelling or pain. Allergies and some autoimmune diseases might also impact IgG4 levels, as they involve the immune system reacting to perceived threats. Medications that affect the immune system, infections, and even genetic factors can play a role too. While lifestyle factors like diet and exercise have less direct effect on IgG4 compared to other biomarkers, overall health and immune function can still influence levels.
If IgG4 levels are high or nearing high, it's important to work closely with a healthcare provider. Treatment may involve medications like corticosteroids to reduce inflammation and calm the overactive immune response. Managing underlying conditions, following prescribed treatments, and maintaining a healthy lifestyle can support your immune system in returning to balance. If levels are low or approaching low, addressing any underlying issues is key. This might include therapies to boost the immune system, ensuring proper nutrition, and taking steps to avoid infections. Regular medical care and following your doctor's advice are essential to improving and maintaining healthy IgG4 levels.
