Effect of Smoking on Blood Parameters and Thyroid Hormones in Men with Polycythemia

Smoking is the primary cause of fatalities, disabling conditions, and avoidable diseases worldwide. Smokers are subject exposed to a variety of dangerous compounds, which stimulate the bone marrow to produce more RBCs. So that, this study aims to know the effects of smoking on men with polycythemia by studying the blood parameters and thyroid hormones. The study is conducted on 100 men (75 with polycythemia and 25 men control), ages (20-59) years, with samples collected from the blood bank at Maysan governorate, from the period November 2022 to March 2023. The results showed an increase significant (P0.05) in the values of red blood cells, hemoglobin and hematocrit, while, the white blood cells count showed no significant (P0.05) differences for both groups of polycythemias (smokers and non-smokers) as compared to the control group. Also, mean corpuscular volume, mean corpuscular hemoglobin and mean corpuscular hemoglobin concentration showed an increase significant (P0.05) in the smokers group. No significant (P0.05) variation was recorded in the values of thyroid stimulating hormone and thyroxine among groups, and triiodothyronine values in polycythemia (smoker and non-smoker) increased significantly (P0.05) in comparison with the control group. According to the above results we conclude the smoking effect in blood parameters and T3 hormones in smoker polycythemia men.
