What happens if you swallow mucus?

When you swallow mucus, it enters your digestive tract and passes through the esophagus, stomach, and small intestine. Most of the mucus is broken down by enzymes and absorbed by the body. Any remaining mucus is expelled in the feces.

Swallowing mucus is not harmful and is actually a normal part of the body's process of clearing out waste products from the respiratory system. However, if you are swallowing large amounts of mucus or if it is accompanied by other symptoms such as a cough, fever, or shortness of breath, it is important to see a doctor to rule out any underlying medical conditions.
