Can bad posture possibly be a cause for frequent urination. I m often told I have bad posture, especially when sitting. The last year I have dealt with frequent urination problems and as you can imagine I m seriously tired of it. It has gotten progressively better and now instead of having to go every 30 seconds I can hold it for up to 2 hours. The confusing thing is that during the night I don t have to get up and really am in no hurry when I wake up in the mornings. This is why posture has come to my mind, because I hold better standing up and sleeping.
