What should you know about hfm cough?

Cough clears mucus and irritants from the airways. A short-lived cough often follows a viral infection such as a common cold or acute bronchitis. A dry cough may accompany allergic rhinitis, asthma, or acid reflux, while a wet cough can occur when mucus is present. Repeated cough over a long period needs assessment for causes such as chronic cough, asthma, or bronchiectasis. The sound alone cannot identify the cause; timing, triggers, mucus, fever, wheeze, and breathlessness add useful clues.

Drink fluids, avoid cigarette smoke and other airway irritants, and rest when an infection is suspected. Note when the cough occurs, whether it is dry or productive, and what makes it worse, such as exercise, cold air, meals, dust, or lying down. Follow prescribed inhalers exactly as directed and do not use someone else's medicine. A pharmacist or GP can help choose symptom relief based on age, pregnancy, existing conditions, and current medicines.

Seek urgent help for severe breathing difficulty, blue or grey lips, chest pain, coughing blood, confusion, fainting, or a rapidly worsening cough. Arrange medical review for unexplained weight loss, repeated chest infections, persistent fever, wheeze, or a cough that continues beyond the expected recovery from an infection. Children, older adults, and people with heart or lung disease may need advice sooner when breathing or feeding becomes difficult.

Ask which features point toward infection, allergy, reflux, or asthma; whether your chest needs examining; and whether testing or an inhaler trial is appropriate.
