What is a Chronic cough and what does it mean?

Chronic cough persists over a long period of time. Cough that lasts for more than eight weeks in adults and four weeks in children can be defined as chronic. It can be a symptom of an underlying disease or condition. Acute cases can lead to depression, vomiting, light headedness and even rib fractures. Only a doctor can detect the underlying problem after examining your body and conducting tests.

A chronic cough is usually accompanied by other signs and symptoms, these include:

  • Wheezing
  • Hoarseness
  • Sore throat and the frequent throat clearing
  • Regular sour taste in mouth
  • Stuffy or runny nose
  • In extreme cases, coughing up blood

Smoking

Asthma
Asthma causes difficulty in breathing and is a long term disease. Sometimes the only symptom that most asthma patients experience is chronic cough. An asthma related cough may get aggravated due to an infection or when they come in contact with cold air, some chemicals or fragrances.

The doctor may recommend blood tests and a few others to determine the possible cause of your cough.

Postnasal drip
Postnasal drip and sinuses can also cause chronic cough accompanied by mucus. This mucus drips down at the back of your throat causing cough reflexes.

Frequent clearing of the throat and a tickling sensation in the throat are a sign of this condition.

Apart from coughing and chest pain, bronchitis can also be accompanied with aches, chills, fever and sore throat.
