Add me to the list too! After years of having to blow my nose just before and during a bowel movement, I resorted to Google to find out what the heck. As soon as my bathroom visit is over, the running of the NOSE stops. I've wondered if it is related to thyroid disease.
I think this may have to do with the foods you are eating. Maybe it is because you are sensitive or allergic to certain foods or, because you are eating spicy foods.
This is amazing. I have been having this for about 3 years. I am a Polio survivor, and am age 63. When my heart starts to beat fast, I know I must use the toilet. It's like a signal. I can be at the computer and not even be aware I need to go and the fast heart starts. Then as I am on the toilet, my nose starts draining as if I had a bad cold. I grab the tissues fast!
I thought it was just me, so I am at least glad to see I am not alone in this.
Maybe this has something to do with the vagus nerve rather than blood pressure, as my blood pressure is usually 110/60. As soon as I finish going, my heart slows and my nose stops running.
I'm 54, and noticed this only a few weeks ago that the nose starts to run as soon as the bowl movement starts. For years I have had to blow my nose after going, but never made the connection in my head. Before I read this thread I theorized that some chemical in the fumes was causing the nose to run - and that the runny nose was a defense mechanism against pathogens, etc.
Had suffered this problem since I was a young girl- even had my glands removed because I blamed them for my stuffy nose! Yes,it gets very stuffy when I need to open my bowels,it is so embarrasing,I had to leave my college!The whole thing ruined my live!And no doctor was able to explain the problem!
I've had this happen for at least 20 years. I'm 50 years old.
Doesn't happen every time. Doesn't seem to be related to fumes.
I don't have high blood pressure. Never had trouble with allergys.
