Coughing every time i drink coffee. why the caffeine causes my cough?

Coughing immediately after swallowing hot coffee unlikely to be a reaction to caffeine. Some people have challanges to drink hot or very cold drinks. If you have a type of swallowing problem from other medical conditions that gives you a chocking sensation, seek medical attention. Meanwhile, drink all liquids when erect, slowly, and in between bites of food, until you see your Doctor.
