What is a Cough?

A cough is your body’s natural way of clearing irritants from your airways. When something like dust, mucus, or smoke enters your throat or lungs, your body reacts by forcing air out quickly to push the irritant out. This rapid expulsion of air makes the sound we recognise as a cough.

It can be caused by various reasons, such as a cold, allergies, or even polluted air. Sometimes, a cough is short-term and goes away on its own. But if it lasts for weeks or comes with other symptoms like fever or chest pain, it might indicate a more serious issue, and seeing a doctor is advised.

Common Types of Cough

Coughs come in various forms, each with distinct characteristics and underlying causes. From the short-lived acute cough to the persistent chronic type, understanding these differences can help identify the best treatment approaches.

Acute Cough

An acute cough is what you often experience during a cold. It lasts for less than a week and is usually tied to respiratory infections like the flu or common cold. This type of cough acts as your body's defence mechanism to clear out the mucus or blockages in your airways.

Chronic Cough

If a cough stretches for eight weeks or longer, it moves under the category of chronic cough. It can be symptomatic of underlying issues such as asthma, acid reflux or gastroesophageal reflux disease (GERD), or chronic bronchitis. Smokers often find themselves plagued with a persistent cough due to the constant irritation caused by smoke and toxins.

Wet or Productive Cough

A wet cough, often described as productive, means there’s mucus involved. Conditions like bronchitis or pneumonia often induce such coughs, where the body tries to rid itself of the excess phlegm produced by the irritation of the airways.

Dry Cough

On the other side of the spectrum is the dry cough, which is annoying because it feels like you're hacking up your lungs without bringing up any mucus. This type of cough can be triggered due to dust or pollen, allergies, or post-nasal drip.

Causes of Cough

Coughs can stem from various causes, each influencing the respiratory system in different ways.

Respiratory Infections

From the common cold to more serious infections like flu or COVID-19, respiratory infections are frequent culprits behind a cough. These lung infections irritate your bronchial tubes, leading to bouts of coughing.

Allergies and Asthma

Both allergies and asthma can trigger persistent coughs. Allergens like pollen, pet dander, or dust mites can lead to allergic reactions that include coughing. Asthma symptoms, on the other hand, constrict and irritate the airways, making a cough a common symptom of the condition.

Environmental Factors

Environmental irritants such as pollution, smog, or chemical fumes from factories can also provoke a cough.

Chronic Conditions

Chronic conditions like Chronic Obstructive Pulmonary Disease (COPD) or Chronic Bronchitis often occur with a chronic cough.

Symptoms of Cough

While a cough itself is a symptom, it often accompanies other signs depending on its cause. For instance, a cough related to a cold may include a runny nose and fever, whereas asthma-related coughs might come with wheezing and shortness of breath. It’s important to monitor your cough and related symptoms to help determine its cause and seriousness.

When to see a doctor for a persistent cough?

If your cough lasts longer than a few weeks or is accompanied by symptoms like chest pain, wheezing, or severe fatigue, it's time to see a doctor to check the underlying causes of respiratory tract infections.

Diagnosing the Cause of Cough

Physical Examination

A doctor’s initial check-up will typically involve listening to your lungs and checking your throat.

Diagnostic Tests

Depending on the suspected cause, a doctor might recommend further tests such as X-rays, a sputum culture, or lung function tests to pinpoint the exact issue.

Home Remedies for Cough

Lifestyle Changes

Simple changes such as avoiding known irritants, staying hydrated, and using a humidifier in your home can also make a big difference in managing a cough.
