I've had a persistent cough for the past three years along with frequent throat infections and mouth ulcers. I recently had sinus surgery, but the cough hasn't gone away. What could be causing this, and is there anything else I should look into?

Also called upper airway cough syndrome, postnasal drip is a common cause of a long-lasting cough. Allergies, viruses, dust, chemicals, or inflammation can irritate your nasal membranes and trigger runny mucus that drips out of your nose and down your throat. This makes you cough, especially at night when you lie down

I'm 33 years old and really struggling with asthma and some gastro issues. Plus, I'm quite overweight at 91 kg, and I think dropping about 20 kg might help with the asthma. Do you have any advice or can you recommend any medicine or tablets that would be suitable for me?
