Hi Dear,

Welcome to HCM.

Understanding your concern.

As per your query nausea and dizziness after smoking cigarettes is because of nicotine which is main ingredient in tobacco. Long term use of nicotine has effect on central nervous system and it activates sympathetic nervous system. This causes release of adrenaline from adrenal medulla into blood stream. Adrenaline causes sudden rush in body and increases heart rate and blood pressure.

This sudden increase in blood pressure is the cause of nausea and dizziness and if you are taking any medication in routine for any other cause then there are chances of nicotine interaction with them and worsening of symptoms.

I would suggest you to quit smoking as that is the only preventing measure. Start reducing first or start using nicotine patches. Keep chewing sugarless candies or chew-gums. Drink alot fluids and water.

Hope your concern has been resolved.

Get Well Soon.

Best Wishes,
Dr. Harry Maheshwari
