Hi ! Good evening. I am Dr Shareef answering your query. Immaterial of the timing of smoking , I would advise you to quit smoking permanently as this could cause severe complications in all the systems of your body, and also for the fetus when you conceive any time in future. The increase in your blood pressure is also a tell tale evidence of the effect of smoking. In case of non stoppage of smoking, one runs all the risks of damage to any organ systems in the body including problems in fertility. So you are the best judge to decide what is good for you, and then act wisely. I hope this information would help you in discussing with your family physician/treating doctor in clearing further doubts on this. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. I wish you could leave smoking for nobody, but for your own and your family health. Dr Shareef.
