I haven't had blackouts necessarily but I have had several episodes when I feel like I am going to pass out. I get very hot and sweaty and light-headed. I talked to my Dr. And he said I need to eat several small meals a day instead of eating three big ones. I have found that it happens when I get hungry. Have you noticed when these blackouts are occuring? Is it when you haven't eaten for a while? It may just be low blood sugar. I'm sure its nothing to worry about, but I would still bring it up to your doctor.

A friend of mine is pregnant and she experienced a blackout a couple of months ago.I think her blood pressure was up a little bit. They said she is fine and her doctors weren't concerned at all.

I went to the dr yesterday and he thinks its my blood sugar levels. I'm scheduled for the glucose tolerance test in a few weeks but in the meantime he wants me to eat fruit and veggie snacks throughout the day. Hopefully, this will help. Thanks for the advice though.

I have had 3 blackouts since my 3rd trimester started... My Ob had asked me to see a cardiologist but after several tests, they still dunno what's wrong with me.

I was in walmart today and I am 23 weeks pregnant. I started getting really hot and started finding it hard to breathe. I began to black out and kept walking thinking it would go away. Before I knew it I was against the floor in the produce section trying to see something. I hadn't eaten that morning so I think that was the problem. It was crazy and fairly embarrassing. Is that normal? I have been having the heat flashes but I have NEVER blacked out like that in my life. It really scared me.
