Overview
Pseudomembranous colitis (PMC) is a severe form of colitis. In this condition, something attacks and injures your colon lining (mucosa). It might be bacteria, toxins or another illness. Your colon mucosa develops thickened, scab-like plaques over the wounds. Your healthcare provider might call these “pseudomembranes.”
What are pseudomembranes?
Pseudomembranes develop on mucous membranes, like your colon lining, when cells die. Your immune system sends white blood cells to the site of the injury. Leftover cellular debris combines with white blood cells called neutrophils to form pseudomembranes. They’re raised areas on the mucosa, up to 2 centimeters (cm) wide, with a yellow-white color.

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.
