Cough: Causes, Duration & When to See a Doctor

Coughing is an important protective reflex of your body, but it can also become a troublesome companion in everyday life. Whether it's a dry, irritating cough at night or thick mucus after a cold: Here you'll learn how to classify your symptoms, what really helps, and how to use brite to check if your medications are triggering or worsening your cough.

In short & important: what you can do right now

Understanding coughs – why they can be so different

A cough (tussis) is not a disease, but a symptom. Your body is trying to clear your airways of foreign objects, mucus, or irritants. We primarily distinguish between a dry, tickly cough (unproductive) and a cough with mucus (productive). The duration and timing – for example, if the cough worsens at night – provide important clues to the underlying cause.

Common causes of cough

Why are you coughing? These are the most common triggers in everyday life:

Infections & colds

Most coughs are a consequence of a flu-like infection. Often, the cough starts dry and becomes productive over time. If the cough persists for weeks, this may indicate bronchial irritation.

Dry cough without a cold (irritants)

Dust, dry air from heating systems, or allergies irritate the receptors in the respiratory tract. Overuse of the voice can also lead to chronic throat clearing.

Reflux & heartburn (coughing at night)

When stomach acid rises into the esophagus, it can trigger tiny nerve irritations that manifest as a dry cough – often right after lying down or at night. Read more about heartburn here.

Cardiovascular connection

In rare cases, coughing can be an indication that the heart is under strain, especially if shortness of breath occurs at the same time during exertion.

Medications as a "cough trigger"

A classic medical factor: Certain blood pressure medications (ACE inhibitors) are known to cause a persistent, dry, irritating cough as a side effect. Interactions between different medications can also make the airways more sensitive.

Is it due to your medication? Get to the bottom of it now

Especially if you have a chronic cough, you should review your medication. brite helps you understand the connection between the pill and the irritation:

• Digital medication plan: Record all medications centrally and immediately recognize whether the cough started with a new prescription or dose change.
• Drug interaction check: Find out if your combination of medications promotes side effects such as coughing.
• Dosage reminder: A stable routine prevents fluctuations that could further stress your mucous membranes.

When should you see a doctor if you have a cough?

Most coughs are harmless, but you should see a doctor if:

• the cough lasts longer than three weeks ("cough won't go away")
• you notice blood in your sputum
• high fever, chills, or severe chest pain also occur
• you are suffering from severe shortness of breath
• you have unintentional weight loss or severe night sweats

Preparing for your doctor's appointment – your checklist

To help your doctor quickly find the cause, prepare this information:

• Type of cough: Is it dry and barking, or is there mucus coming out?
• Color: If there is mucus present, what color is it (clear, whitish, yellow-green)?
• Timing: Do you cough mainly at night, during exertion, or after eating?
• Medications: Bring your complete list from the brite app – especially blood pressure medications are crucial for the doctor.
