yes.
for 2 reasons you might suffer 2 typs of anemia:
1-reduced RBC and hemoglobin,while your ferritin and transferrin are normal.
this type happens to all who quit smoking analogs,since analog produce carbon monoxide,and this is a good hemoglobin competitor for oxygen in the blood,thus the body initially suffers from mild hypoxia,and as a result,it raises the hemoglobin level in the blood of all smokers,to about 10-15% more then they would have otherwise.
thus, stopping inputting carbon monoxide,that is absent in
vaping,will cause your hemoglobin an RBC count to fall,but they shouldn't fall more than 10-15% of the value you had as a smoker.
example-if you had HB 16 as a smoker,you shouldn't go lower than HB 13.6.
2-anemia that has abnormally low ferritin and transferrin.
this is usually caused by a GI bleeding,indicating that you might have an stomach-intestinal ulcer.
were you suffering lately from:
1-black stool?
2-stomach aches?
3-chest pain?
4-trouble swallowing?
5-hurt burns?
6-hemorrhoids?
if you answered "yes" to one of these,than that should be the cause,and you should have it screen and fully diagnosed for treatment.
since it might be caused or exaggerated by the increasing intake of nicotine,that solves in your saliva,via transmitted to your GI system.
if no-than you should seek medical attention for further more screening,for less likely causes of anemia (i.e kidney function. complete blood count,folic acid,b12 levels etc...)
