Thank you for asking on Chat Doctor! I understand your concern and would explain that low blood pressure is not related to smoking in fact smoking can lead to high blood pressure or increased peripheral vascular resistance. I recommend performing some tests to investigate for the possible causes: - complete blood count for anemia-blood electrolytes for possible imbalance-thyroid hormone levels for possible thyroid dysfunction- vitamin D and vitamin B12 plasma levels-cortisol plasma levels for possible a Chat Doctor. You should discuss with your doctor on the above tests. Meanwhile, I would recommend taking plenty of fluids to stay well HY
