Overview
Immunoglobulin A (IgA) is a protein found in the blood. It protects the body against infections in the membranes (thin tissues) that line the airways, eyes, mouth and digestive system.
People with selective IgA deficiency don’t have this protein or have very low levels (deficiency) of the protein. Selective IgA deficiency is an immunodeficiency disease (a disease that involves a lack in the immune system). You might also see it called SIgAD.

Complications
Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
- High blood pressure.
- Diabetes.
- Heart failure.
- Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.
Prevention
Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
- Control high blood pressure, high cholesterol and diabetes.
- Don't smoke or use tobacco.
- Eat a diet that's low in salt and saturated fat.
- Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
- Get good sleep. Adults should aim for 7 to 9 hours daily.
- Maintain a healthy weight.
- Reduce and manage stress.
