Throat cough: what to know

A common cold can inflame the throat and trigger coughing. Mucus draining from the nose may cause a tickle, while acid reflux can irritate the throat, especially after meals or when lying down. Wheezing, chest tightness, or cough brought on by activity can point to an airway problem such as asthma. A cough that lasts or repeatedly returns needs a clinician to look for causes including chronic cough or other lung conditions.

Describe whether the cough is dry or brings up mucus, whether it wakes you, and whether smoke, dust, exercise, meals, or cold air trigger it. These observations are more useful than trying to identify the cause from the cough alone.

Drink fluids, use warm drinks if soothing, and avoid smoke or strong fragrances. Rest your voice and consider a humidified room if dry air aggravates the throat. If reflux seems connected, avoid lying down soon after eating and discuss persistent symptoms with a clinician. Use cough medicines only as directed and check ingredients before combining products.

Seek urgent help for severe breathing difficulty, blue or grey lips, chest pain, coughing blood, confusion, or sudden worsening. Arrange medical review for wheezing, dehydration, fever with marked illness, repeated nighttime symptoms, or a cough that persists or interferes with sleep and daily activities. Children, older adults, and people with lung disease may need advice sooner.

Ask whether the pattern fits a cold, reflux, nasal allergy, asthma, or another cause; whether your chest needs examination; and which treatments suit your age and medicines. Mention smoking or vaping, allergies, recent infection, and any breathlessness.
