Can constipation cause nausea?

Question

This may sound like a dumb question... But I've never been constipated in my life. I'm 11 weeks and haven't been nauseous much at all this pregnancy. But last night and today I have felt yuck nausea. it dawned on me that I haven't used the bathroom in about 3 or 4 days. I was put on vitamin d supplements last week and not sure if that can cause constipation, but I was wondering if that might cause my nausea? I finally had a few bowel movements today and I'm feeling better but not 100%.

Answer

Not a dumb question at all, but yes comstipation can cause nausea. Make sure you drink plenty of water! I know it’s hard to drink water when nauseous but being dehydrated can make you constipated, and nauseous!! Also, eat some prunes/drink prune juice ! It will help you go to the bathroom.

Answer

Not a dumb question. Constipation can absolutely cause nausea and vomiting. I had surgery during my last pregnancy and afterwards had strong painkillers that made me really constipated. One day I threw up like 20 times, I couldn’t keep anything down and felt horrific. The doctor came round and said it was due to constipation. He gave me laxatives and it worked so well. Once I was no longer constipated the nausea went away. I have a similar situation now. I’m 10 weeks pregnant and suffering with all day bad nausea. So I’ve been taking ondansetron to help. It’s been great with the nausea but now I’m constipated again and have had to stop taking the medication because I don’t want to end up so back up that I’m vomiting again. It’s a catch 22!

Answer

It absolutely can. I take milk of magnesia when I can’t go and it helps within 30mins.
