Cough 101: What you need to know to decode your cough
Everyone knows the feeling: the sudden urge to clear your throat followed by the deep, familiar echoes of a cough. With so many potential causes, it's no wonder that a cough can raise eyebrows, especially when everyone's on high alert during cold and flu season. Is that cough as grim as it sounds? Does the cough mean you need to see a doctor? Find out what your cough might mean, common misconceptions, and when you should see an MDLIVE board-certified doctor.
3 things you might have wrong about your cough.
1. The length of my cough isn't that important.
One of the most common misconceptions is that the sound of a cough is the only thing that matters. However, contrary to popular belief, the duration of a cough is often more important in determining the severity of the underlying condition. There are three different types of coughs based on duration:
Typically lasts less than 3 weeks. These are often associated with short-lived illnesses.
Typically lasts 3-8 weeks. They sometimes hint at an unresolved infection or post-viral syndrome.
Lasts more than 8 weeks in adults or 4 weeks in children. Chronic coughs can indicate an underlying issue, like asthma or allergies.
2. A scary-sounding cough? Must be serious!
Sometimes, a cough can sound scary. But don't judge a book by its cover. A loud cough doesn't always mean something terrible or indicate a severe underlying condition. While a cough can be a vital symptom in determining the underlying issue, it should always be evaluated in conjunction with other symptoms.
3. I haven't coughed; I must be fine!
It's easy to think that if you're not coughing, you're not sick. But that's not always true. Some common adult and adolescent illnesses, like strep throat, mononucleosis, roseola, or hand, foot, and mouth disease, don't usually come with a cough. Remember, diseases can show up in different ways – and sometimes, coughs develop later.
How to alleviate cough symptoms
"First, make sure you are providing your body with plenty of fluids, as staying hydrated can help loosen mucus and make it easier to expel. Hot teas can also help to soothe an irritated throat. Consider natural or locally grown honey as a bonus, as it acts as a natural cough suppressant, helping to reduce the frequency and severity of coughing."
If you're dealing with a persistent cough, cough drops can be a handy quick fix. They make your mouth produce more saliva, which helps soothe your throat and ease that nagging, itching feeling.
You might have noticed that steamy showers make you feel better when you're sick. Adding moisture to the air through a shower or a humidifier can help open up your airways and loosen a stuffy nose.
When nothing else seems to work, you can consider using over-the-counter cough medicine. For dry coughs, a cough suppressant that contains dextromethorphan can be effective in blocking the cough reflux. For a wet cough producing mucus or phlegm, an expectorant can help thin and loosen mucus, making it easier to cough up. However, it's important to consult a doctor before starting any medication. A doctor may recommend an alternative treatment if your cough is due to an underlying condition, like asthma or GERD.
