I am just getting over a very bad case of strep throat, and during that time I started my period at a normal date and everything, normal flow if not a just a wee bit heavy. However, as the strep went on I was unable to eat or drink pretty much anything because my tonsils became so inflamed, and I was just wondering if the dehydration may have been the cause of my period ending a few days early and fairly suddenly.
It could be...but, with anything serious / medical, etc, you really should consult a doctor or nurse for a professional opinion.
When I was sick recently, I had issues, um, using the restroom, due to severe dehydration - I'd imagine most of the bodily functions we have get impacted by that, since it's fairly traumatic for the body.
The same happened to me over my christmas break from college, except what happened with me was that I started my period late. I think my period ended pretty quickly too, which is really abnormal for me. I also couldn't eat or drink anything also causing me to lose alot of weight.
