Uh, oh! You feel a tickle in your throat, and then a cough soon follows. What is causing your cough, and how should it be treated? We all get a cough occasionally, but a cough that continues for weeks or months could be a sign of a medical problem.
What Is a Cough?
A cough, also known as tussis, is a voluntary or involuntary act that clears the throat and breathing passage of foreign particles, microbes, irritants, fluids, and mucus; it is a rapid expulsion of air from the lungs. A cough is your body’s response when something irritates your throat or airways.
Types of Coughs
An “acute” cough lasts less than three weeks. A “chronic” cough lasts longer than eight weeks (four weeks in children). While acute coughing can often be attributed to factors such as respiratory infections or environmental pollutants, chronic cough presents a more challenging diagnosis.
Common Causes of Acute (Short-Term) Cough
- Inhaling an irritant (such as smoke, dust, chemicals, or a foreign body)
- Pneumonia, an infection in one or both lungs.
- Viral infections, such as the common cold or flu
- Whooping cough
Mutual Causes of Chronic (Long-Term) Cough
- Allergies
- Asthma (most common in children)
- Bronchitis
- Gastroesophageal reflux disease (GERD)
- Postnasal drip
At-Home Remedies for Cough
Here are some at-home treatment options you can try at the onset of a cough.
- Avoid tobacco smoke. Smoking or breathing secondhand smoke can make your cough worse.
- Consider taking honey. A teaspoon may help loosen a cough. Don’t give honey to children younger than one year old, however, because it can contain bacteria harmful to infants.
- Drink fluids. Liquid helps thin the mucus in your throat. Warm liquids like broth or lemon tea can soothe your throat.
- Moisturize the air. Use a cool mist humidifier or take a steamy shower.
- Use cough drops or hard candies. They may ease a dry cough and soothe an irritated throat. Don’t give them to a child under age 6, however, because of the risk of choking.
The Effectiveness of Cough Medicine
Cough medicines are usually only used for short-term coughs that cause a lot of discomfort, interfere with sleep, and are not associated with any of the potentially worrisome symptoms indicated above. If you use cough medicine, be sure to follow the dosing instructions.
Over-the-counter cough and cold medicines are intended to treat the symptoms of coughs and colds, not an underlying disease. Research suggests that these medicines haven’t been proven to work any better than inactive medicine (placebo). More important, these medications have potentially serious side effects, including fatal overdoses in children younger than two years old.
Don’t use over-the-counter medicines, except fever reducers and pain relievers, to treat coughs and colds in children younger than six years old. Also, consider avoiding using these medicines in children younger than twelve years old.
And remember: Coughing isn’t all bad. It helps clear mucus from your airway. If you or your child is otherwise healthy, there’s usually no reason to suppress a cough.
When Is It an Emergency?
If a doctor decides that a cough is caused by a viral infection, such as the common cold or flu, the advice is typically to rest, drink plenty of fluids, and let it run its course. Generally, such coughs clear up after 1 to 2 weeks.
A cough caused by a viral infection that persists for more than a couple weeks will probably require medical attention.
When to Visit Urgent Care
If a cough has persisted for 3 weeks without improvement, it’s a good idea to go to urgent care to find out what is causing it.
Symptoms That Warrant a Visit To the ER
Symptoms such as difficulty breathing, chest pain, coughing up blood, or unexplained weight loss serve as red flags and signal the need for a visit to the emergency room.
These warning signs may indicate an underlying condition:
- Coughing up thick, greenish-yellow phlegm
- Wheezing
- Experiencing a fever
- Experiencing shortness of breath
- Experiencing fainting
- Experiencing ankle swelling or weight loss
Seek emergency care if you or your child is:
- Choking or vomiting
- Having difficulty breathing or swallowing
- Coughing up bloody or pink-tinged phlegm
- Experiencing chest pain
Diagnosis
A doctor will ask about your medical history and perform a physical exam. A thorough medical history and physical exam can provide important clues about a prolonged cough.
Many doctors will opt to start treatment for one of the common causes of chronic cough. However, if the treatment doesn’t work, you may undergo testing for less common causes. The doctor may order some diagnostic tests.
- Computerized tomography (CT) scans- CT scans may also be used to check the lungs for conditions that may produce chronic cough or the sinus cavities for pockets of infection.
- Spirometry- Spirometry is a standard test that doctors use to determine how well your lungs are functioning. The test works by measuring airflow in and out of your lungs. The test is common with asthma.
- X-rays- Although a routine chest X-ray won’t reveal the most common reasons for a cough, postnasal drip, acid reflux or asthma, it may be used to check for lung cancer, pneumonia, and other lung diseases. An X-ray of your sinuses may reveal evidence of a sinus infection.
If asthma is diagnosed, the patient may be prescribed asthma medication. A doctor might refer the patient to a lung or ear, nose, and throat (ENT) specialist in special cases.
Preventing A Cough
The best way to prevent a cough is to reduce your risk of catching a virus or bacterial infection. You can take the following steps:
- Frequent hand washing or using 70% alcohol sanitizer
- Flu or pneumonia vaccinations for high-risk patients
- Limiting exposure to irritants such as smoke
