349 Best Doctors for Cough available in Bangalore

The cause of a cough varies based on the duration. The common causes of short-term cough include cold, flu and pneumonia. Persistent long-term cough can be due to reflux of acid into the food pipe from the stomach, smoking and bronchiectasis (the broadening of the airways in the lungs). Bronchitis, sinusitis, allergy and asthma may lead to either short-term or persistent cough.

You should consult a doctor if you have a cough for more than three weeks or if the cough is getting severe. Immediate medical attention is needed if:
- You see blood in the cough
- You are experiencing unexplained weight loss
- Your voice has changed
- You have a swelling in the neck region

In addition to physical examination and medical history, the following tests are useful in the diagnosis of the cause of cough:
- Blood test
- Chest x-ray
- Throat swab
- CT scan of the chest
- Sputum (mucus) sample test
- Spirometry, in which you will be asked to blow out the air into the plastic to assess your ability to breathe

The following are some homecare methods for managing cough:
- Drink plenty of liquid which helps thin the mucous
- Quit smoking, as it causes irritation in the throat
- Take honey as it can help loosen the cough
- Cough drops or hard candies can help soothe the throat
- A steamy shower can also soothe the throat

Based on the underlying cause, the droplets of cough may lead to spread of bacteria or virus. It may not spread from person to person if it is due to a blocked or obstructed airway, or due to gastric reflux disease.
