Living with cough

Overview

A cough is your body's natural way of clearing your airways. It helps get rid of mucus, irritants, or germs from your throat and lungs. Most coughs are not serious and go away on their own, but a cough that lasts a long time may need medical care.

Yes. Coughing is one of the most common reasons people visit their doctor. Almost everyone has a cough from time to time.

Coughs can affect anyone at any age. Children and older adults tend to have more frequent or more severe coughs, especially due to infections or changes in the immune system.

Symptoms

Common symptoms

• Dry or tickly cough
• Chesty cough with mucus (phlegm)
• Cough that gets worse at night
• Sore throat or hoarse voice
• Wheezing or a whistling sound when breathing
• Feeling short of breath

Symptoms in children

• Cough with a runny nose or mild fever
• Barking cough (often called croup)
• Cough that is worse when lying down
• Coughing after playing or laughing

Symptoms in older adults

• Cough that lasts longer than expected
• Tiredness or weakness
• Shortness of breath during light activity
• A cough that disrupts sleep

Causes

Main causes

• Viral infections like colds, flu, or COVID-19
• Allergies or irritants such as dust or smoke
• Asthma or other lung conditions
• Acid reflux (stomach acid going up into your throat)
• Post-nasal drip (mucus dripping down the back of your nose)
• Some blood pressure medicines or other certain medicines

Risk factors

• Smoking or breathing in secondhand smoke
• Living in areas with poor air quality
• Having a weakened immune system
• Long-term lung disease like asthma or COPD
• Being around young children, who often carry colds and flu

When to see a doctor

See a doctor urgently if:

• Cough lasting more than 3 weeks
• Coughing up blood or rust-colored mucus
• Unexplained weight loss or fever at night
• Cough that interferes with sleep, work, or daily life

Book a routine appointment if:

• A cough that goes away but keeps coming back
• Cough with wheezing or a tight chest
• A cough that started after starting a new medicine
• Persistent cough in a person with a heart or lung condition

Diagnosis

A doctor will ask about how long you have been coughing, whether you have other symptoms, and whether you smoke or have any health conditions. They will also listen to your chest with a stethoscope.

Tests that may be done

• Chest X-ray to check your lungs
• Breathing tests (spirometry) to see how well your lungs work
• Swab from your nose or throat to check for infections
• Blood tests if they suspect an underlying condition

What to expect at your appointment

You may be asked to cough into a cup or have a small device used to measure your breathing. Most tests are quick and painless. The doctor will explain what they find and what you can do next.

Treatment

Treatment for a cough depends on the cause. If a virus is behind it, the best approach is rest and comfort. If it is caused by asthma, allergy, reflux, or an infection, treating that underlying problem will usually help the cough go away.

Self-care at home

• Drink plenty of water to keep your throat moist
• Rest until you feel better
• Use a humidifier or take a steamy shower to ease a dry cough
• Avoid smoke and strong fumes
• If you have a dry cough, a teaspoon of honey (for adults and children over 1 year) may help soothe your throat

Medical treatments

Doctors sometimes suggest cough medicines that reduce the urge to cough or help clear mucus. However, these are not always effective. The most important treatment is targeting the cause. For example, an inhaler for asthma, allergy medicines for allergies, or acid-reducing tablets for reflux. Antibiotics are only used when a bacterial infection is confirmed, because they do not work for viral coughs. Always ask your doctor or pharmacist for advice.

When is surgery considered?

Surgery is rarely needed for a cough. It may be considered if a structural problem, such as a growth or damaged airway, is causing the cough and other treatments have not worked.

Living with this condition

Try to get good rest and drink plenty of fluids. If you have a chronic cough, keep a symptom diary to notice what makes it better or worse. This can help you and your doctor find the best plan.

Lifestyle tips

• If you smoke, quitting is the single best step for your lungs
• Wash your hands often to avoid spreading or catching infections
• Cover your mouth and nose when you cough
• Stay away from things that trigger your cough, like perfumes, cold air, or dust

Diet and exercise

Eat a balanced diet to keep your body strong. Gentle exercise, like walking, is usually fine if you feel up to it, but avoid vigorous activity when your cough is severe or you have a fever. Always listen to your body.

Mental health and emotional wellbeing

Living with a long-lasting cough can feel frustrating and exhausting. It might affect your sleep, your voice, or your social life. It is normal to feel anxious or low. Talk to your doctor if it is affecting your mood or daily life.

Prevention

Not all coughs can be prevented, but you can reduce your chances of getting them. Good hand hygiene, staying away from people who are sick, and avoiding smoking or air pollution are important steps.

Vaccines

Some coughs can be prevented with vaccines. For example, vaccines for flu, whooping cough, and pneumonia can reduce your risk. Ask your healthcare provider or local health service which vaccines they recommend for you.

Screening programmes

There is no routine screening for a cough itself. However, if you have chronic lung disease or other risk factors, your doctor may recommend regular check-ups to keep your lungs healthy.

Complications

If left untreated

• Sleep problems from coughing at night
• Sore or strained chest muscles
• Headaches or dizziness from intense coughing
• Urinary leaking (especially in women)
• A hidden underlying problem, like asthma or reflux, getting worse

Long-term outlook

The outlook for a cough is usually very good. Most coughs go away on their own within a few weeks. Even a chronic cough can be improved or well managed once the cause is found. With the right care, most people are able to carry on with their normal daily lives.
