  2. Pressure increases in the throat and lungs due to vocal cords being closed.
  3. A soaring release of air occurs when the vocal cords are opened and cough is able to produce a distinctive sound.

If someone coughs frequently often, it could be an indication of an illness. A lot of coughs are caused by infections, such as the common cold, however, there are many other non-infectious causes. We examine some possible reasons in the following section.

The Reasons

A majority of the coughs are caused by viral infections and are treated with no treatment.

The causes of cough that are acute (short-term) cough

Most of the time the problem is located found in the respiratory tract of the upper and is affecting the throat. This is known as an Urticaria (or URI) ( upper respiratory tract infection). Examples include:

  • flu
  • common cold
  • laryngitis

If it’s an LRTI (lower respiratory tract infection) then the lung is infected and the airways are lowered down from the windpipe. Examples include:

  • bronchitis
  • pneumonia

An acute cough could result from allergies like hay fever.

The causes of long-term (long-term) cough

A chronic cough could be the result of:

  • smoking
  • mucus drips into the throat from the inside of the nose (post nose drip)
  • GERD (gastro-esophageal reflux)
  • asthma
  • Certain medicines (e.g., ACE inhibitors)

Children who suffer from chronic coughs tend to be caused by asthma, but they can also be caused by conditions like post nasal drip and GERD.

Some of the less common factors for chronic cough in adults are TB (tuberculosis), fungal infection of the lungs, and lung cancer.

When should you see a doctor?

If the cough persists for more than 3 weeks and there is no improvement, it’s advisable to consult a physician.

In the majority of cases, it is unlikely that there is anything serious behind the cough. However, in some cases, chronic coughs can be an indication of something that requires attention, like lung cancer, or cardiac failure.

Additional reasons for seeking medical advice are:

  • The cough is becoming more severe.
  • There may be lumps or swelling found in the neck area.
  • Weight loss.
  • A severe cough.
  • Trouble swallowing.
  • Changes in the vocal sound.
  • Sucking up blood.
  • Trouble breathing.
  • Chest pain.
  • Fevers that aren’t getting better.


If a doctor determines that the cause of a cough is influenza or the cold the usual advice is to take a rest, drink plenty of fluids and let the illness run its course. In most cases, these coughs will disappear within a few weeks.

A cough that is caused by an infection with a virus that lasts for longer than a few weeks may require medical care.

The doctor could order diagnostic tests, for instance, an X-ray chest scan; Phlegm samples could be taken to a lab to be analyzed in order to find out what’s causing the infection.

The patient could be required to breathe in and out through the tube that is attached to a machine. This will help the doctor determine if the airways are blocked (this test is known as spirometry) This is a common test in asthma and Emphysema.

If asthma is identified and the patient is diagnosed with asthma, they may be given asthma medications.

Sometimes, a doctor may recommend the patient to an ear, lung, or nose and throat (ENT) doctor.


The most effective way to deal with a cough caused by an infection caused by viruses is to let your immune system take care of it. Generally, it will go away without delay.

If a physician is treating coughs, they’ll concentrate on the root of the problem such as, for instance when it’s caused by the ACE inhibitor, it could be stopped.

Codeine dextromethorphan, codeine, and other coughs relievers are frequently employed by cough sufferers.

But, there’s little research about cough remedies and the extent to which they actually help reduce symptoms.

Home remedies

As per the National Health Service (NHS), in the United Kingdom, a home remedy using lemon and honey is just as good, even better than many available over-the-counter (OTC) items sold in pharmacies.

Treatments tend to focus on making the patient feel slightly better, but they typically do not reduce the length or duration of cough.

Honey is a natural substance that is a throat-coat, which results in less irritation and less coughing. It is also a desulcent (something which soothes).

Certain medicines can help with symptoms associated with it, for example, fever or congestion of the nose. But, there’s no conclusive evidence that suggests that cough medications can make the cough less severe. A wide range of cough medicines can be purchased to purchase on the internet.

For children who are small, it’s a good idea to speak with an experienced doctor prior to giving OTC cough medications. Some of the ingredients in medications like codeine are dangerous for young children. There is no proof that cough medicine is beneficial for children and could actually be harmful due to its side effects.

Cough suppressants -these reduce the reflex of coughing and are typically used to treat dry coughs. Examples include pholcodine as well as dextromethorphan. antihistamines.

Expectorants — they aid in bringing mucus as well as other substances from the trachea, bronchi, and lungs. A good example is Guaifenesin (guaiphenesin) that thins the mucus. It helps to lubricate the respiratory tract, helping rid the airways. Expectorants for cough are available to buy over the counter or on the internet.


In the end, the fact that coughs can be irritating and uncomfortable. However, in the majority of cases, they’ll go away by themselves. If, however, you have a persistent cough for a while or get worse, it’s essential to consult an expert.
