Atrial fibrillation (AFib) is a heart rhythm disorder that may increase your risk of stroke. With AFib, the upper two chambers of your heart beat irregularly. Blood may pool and collect, creating clots that can travel to your organs and brain. Doctors often prescribe anticoagulants, or blood thinners, to thin the blood and prevent clots from forming. Here’s what you need to know about long-term blood thinner use, any side effects you might experience, and what you may want to discuss with a doctor.

The pain and burning of heartburn occur when stomach acid comes up from your stomach and into your esophagus. If it happens every day, this can be a serious condition that needs medical care. Heartburn occurs when acids from the stomach irritate the esophagus, the back of the throat. This condition may cause discomfort, reflux, or other symptoms like bad breath or cough. Symptoms may worsen in the evenings, after meals, or when a person is lying down, bending over, or exercising.
