Cough: There are vanniloid receptors and distinct cough receptors in the respiratory epithelium. This sends the signal to your brain to cough.

A 32-year-old member asked:

What could cause someone to start coughing under heavy sedation?

Aspiration: Under heavy sedation, the ability to handle one's saliva is compromised. One of the most powerful reflexes is when a foreign body, such as saliva, enters your airway. This is but one possibility.

Aspiration: The stimulation of your upper airways is a very strong stimulant. With sedation, your ability to manage the liquid in your mouth like saliva is compromised and can fall into your trachea. This can provoke a very strong coughing reaction.

Multiple causes: Could be your airway collapsing (sleep apnea) as you transition from wake to sleep. Other common causes of cough that's worse/only present at night include acid reflux, and post nasal drip. See you doctor and get a more thorough evaluation/history. Appropriate testing, if indicated, will happen from that point. Good luck!

Does a cold start with a cough?

Not necessarily.....: A cold is usually the result of an upper airway infection while a cough can be the result of a lower respiratory infection. However, you can also get a cough from post-nasal drip, which can be due to an upper airway infection. Usually, though, symptoms such as nasal congestion, sore throat will precede the post-nasal drip cough. When in doubt, see your doctor.

What happens if whenever drinking or eating you start coughing?

Dysphagia: Dysphagia or difficulty swallowing as evidenced by coughing upon drinking or eating suggests an inability to protect your airway. This needs to be evaluated to uncover cause in order to offer you appropriate treatment. Start w/your family doc who can then make referrals as appropriate. Take care of this as soon as possible to minimize your risk for aspiration pneumonia: food ; drink down windpipe.
