What Could Dizziness/fainting Post Urination Suggest?

Is it common for men to faint after urinating. I ve had the feeling of fainting a few times while urinating and last night I actually did faint after urinating. This is usually after drinking (not heavily) and during the night. I think it might have been because I got out of bed too quickly to go to the toilet, and then whilst going to the toilet it seemed to make it worse and once finished, I then fainted, fell over and banged my head on the floor.

Hello,

The postural hypotension while urination is not normal and must be warranted sign of an underlying issue with the endocrine malfunction.

Immediate consultation with an expert endocrinologist is mandatory to solve the issue at earliest.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Hello,

It is the poly urination, which is provoking postural hypotension when much of the fluid is lost in urine; the body tries to manage the depth via vasodilatation of the peripheral blood vessels which will drop blood supply to the brain transiently.

Hope I have answered your query. Let me know if I can assist you further.
