I smoke too much. Much less than  I used to, however. I want and need to quit. Lately I have noticed huge bruises on my body where I thought I was just scratching an itch. I look beat up. My nurse friend mentioned low blood platelets... does cigarette smoking lead to thrombocytopenia? Im scared - want to quit desperately! Want to be healthy for my kids.
Hello, if you want to be healthy you should quit smoking anyway, but smoking does not cause low platelets. Bruising may be caused by a low platelet count but can also be caused by blood vessel fragility and platelet dysfunction. Sometimes Chat Doctor.  You should do a complete blood count with microscopic examination of the specimen and perhaps also consult a hematologist. Kind Regards!
