What can be the reason for low platelet count?

my cousin is being induced today due to it. i have read in my text books it can be caused by increased exposure to ionising radiation or cancers such as leukemia. it is not due to this in her case so is it just as she is pregnant or could it be down to something else?

i havent really spoke to her much about it as she has moved so i don't see her as often x

could be due to Anaemia in pregnancy caused by low iron levels I had this...not to leukima also but something similar they were gunna give me a small bone marrow transplant if my platelets didnt increase but luckily they did as I was taking iron supplements and had 3 blood transplants to get my platelet and iron levels up
Good diet usually helps,red meat green veg.Liver and brocolli are excellent.

I bet a couple of weeks after pregnancy she'll be right as rain.
It just sounds like mine-Anaemia brought on by pregnancy.
Good Luck to her and congrats to her on the little bubba.

It could be due to the pregnancy. Did they say anything about her iron level?

my wife had low iron level which caused the low platelet count

It could be any allergy, including to drugs. Or, if she has been bleeding internally (which is more serious) it could be caused by consumption of the platelets. I am sure she is in good hands, and she will be alright.
Good luck and congrats for a new nephew/niece!
