Ahem, ahem! Someone who constantly clears his or her throat could have a nose and sinuses problem, called chronic rhinitis, which results in excessive mucus production. It occurs when an irritant (typically allergies) inflames the membrane in the upper respiratory tract. People with year-round allergies, like house dust mites, may have a constant build-up of mucus in their throat, which leads to that non-stop clearing. It can usually be treated with a few weeks of a strong anti-allergy medication. Another potential cause: acid reflux. When acid passes from the stomach upward into the oesophagus, the throat swells. Mucus sticks to the swollen tissues, causing hoarseness and a cough. If over-the-counter heartburn medications don’t resolve the issue, a doctor may be able to prescribe stronger treatment.
