Question: Dizziness when having bowel movements
|MikeInVA - Tue Jan 25, 2005 3:36 pm||
I have been having dizziness when having a bowel movement. This occurs if I strain to push something out. I am not constipated but I do have to push many times to get things out. If I don't strain I don't get dizzy only when I strain. The frequency has increased lately. I don't have dizziness any other time.

What you have described can be related to a condition known as Vasovagal syncope. If it is related to certain situations it is named as (situational syncope). These situations include passing urine, coughing, defecation. the mechanism is due to activation of adrenergic tone(sympathetic), followed by vagal(parasympathetic) over activation . a presyncopal phase in the form of epigastric discomfort, dizziness or vertigo, and nausea usually preeced and if the person does not lies down or is a way from the triggering stimulus he can faint.
Iif the frequency is increased as you mentioned, you should arrange to see you doctor soon, as The diagnosis is made mainly by careful history and examination. then he can recommend the required investigations and the proper medications.
