Diagnosis
Your doctor will ask about your cough and other symptoms, listen to your chest with a stethoscope, and check your oxygen levels. They may also ask about your medical history.
Tests that may be done
- Chest X-ray (if pneumonia or other serious cause is suspected)
- Sputum test (checking your mucus for infection)
- Breathing tests (if asthma or COPD is possible)
What to expect at your appointment
Most people do not need tests. Your doctor will explain what is causing your cough and give you advice. If testing is needed, it will be explained to you step by step.
Treatment
Most coughs get better with home care and time. Treatment focuses on soothing your throat and helping your body fight off the underlying cause.
Self-care at home
- Drink warm fluids like honey and lemon water or herbal tea
- Rest as much as possible to help your immune system
- Use a humidifier or sit in a steamy bathroom to loosen mucus
- Avoid smoke and other irritants
- Try a teaspoon of honey at bedtime (for adults and children over 1 year)
- Elevate your head with extra pillows to help you sleep better
Medical treatments
Your doctor may recommend over-the-counter cough remedies, such as expectorants to thin mucus or suppressants to calm a dry cough. Never give cough medicine to children under 6 years without a doctor’s advice. Antibiotics are not used for viral coughs.
When is surgery considered?
Surgery is rarely needed for a cough. It may only be considered if an underlying problem like a growth or structural issue is found.
Living with this condition
Take care not to spread germs. Cover your mouth and nose when you cough, wash your hands often, and stay home if you feel unwell. Keep a drink nearby to soothe your throat.
Lifestyle tips
- Quit smoking or avoid secondhand smoke
- Keep your home clean and dust-free
- Use a scarf or mask in cold or polluted air
- Get plenty of rest and avoid overexertion
Diet and exercise
Eat a balanced diet with fruits and vegetables to support your immune system. Gentle exercise like walking can help, but avoid strenuous activity until your cough improves.
Mental health and emotional wellbeing
A lingering cough can be frustrating and make you feel isolated. It’s normal to feel tired or worried. If your cough affects your mood or sleep, talk to someone you trust or a healthcare professional.
Prevention
You can lower your risk by staying away from sick people, washing hands often, and avoiding smoking. Living a healthy lifestyle helps your immune system fight infections.
Vaccines
Getting the flu vaccine each year can help prevent the flu, which often causes a cough. Pertussis (whooping cough) vaccine is also recommended for children and adults. Talk to your doctor about what vaccines are right for you.
Screening programmes
There is no routine screening for cough. If you have risk factors or cough that lasts, your doctor may recommend check-ups.
Complications
If left untreated
- Pneumonia (lung infection)
- Chest infections that spread to other parts of the body
- Broken ribs (from severe coughing)
- Fainting or dizziness (from prolonged coughing fits)
Long-term outlook
Most coughs fully recover with simple home care and time. Even if a cough lasts longer, treatment is available and effective. Following your doctor’s advice helps you heal faster and prevent complications.
