What causes black specks in stool?

default
Posted on Wed, 12 Nov 2014
Question: I recently found out I am pregnant, 5 weeks. The last few days I have had black specks in my stool (exactly like sesame seeds). The stool itself is normal in substance and color. I have no stomach pain. I wrote my doctor and he seems to think it is due to pregnancy, and maybe bowel motility. I am so nervous they are parasite eggs.

Brief Answer:
Increased bowel motility

Detailed Answer:
Parasite eggs are so so small that they do not actually appear with naked eye, they have to be observed under 10-30x magnification. So I do not think of parasite eggs.

I agree with your doctor that pregnancy can have faster bowel motility. So the food that you consume daily could have something that is not fully digested and passed after partial or no digestion. These food pieces appear as black sesame seeds or sesame seeds itself were not digested.

I would also like to enquire if you take Iron preparations which are commonly supplement during pregnancy. You mentioned no medications but I wish to find if you take Iron preparation then there is change in the color of the stool. This is just another insight I give.

Okay great, thank you. Yes, I do take OB Select with DHA, which is a pre-natal vitamin that has Iron in it.
