Today i think i have swallowed a bristle of toothbrush. i have vomitted several times but nothing came out. will it effect me in future . i have drink lot of water i think it is in my stomach now?

I would continue eating and drinking as usual. Keep observing your stool to see when it passes. You should be OK.

Most probably,it is out of your system . Just keep watching,if any symptom in stomach develops see a GI Doctor It is more important to change your toothbrush with New ADA approved Tooth brush every three months to avoid future incidence like this .
