I drink a lot of water and other fluids and would like to know if it is normal to have urinate every hour to an hour and a half. I currently take a vitamin D supplement and am told this may cause me to have to urinate a lot.

Not unless you are on some sort of Diuretic medicine (such as for high blood pressure as one example).

I think your question belongs to different forum

Well, strictly speaking, it is a plumbing question.

Vitamin D is a fat soluble vitamin. It should have little effect on urination UNLESS you take so much that you get hypervitaminosis and then frequent urination is indeed a symptom. Check with your doctor as to Vitamin D levels in your blood and appropriate dosage.

I have the urge to urinate every 45 minutes daytime and 60 - 90 minutes when sleeping. This goes back 35+ years, and I finally found out the reason - scarred sacral nerves hitting one side of my bladder. It took a chiropractor to diagnose it (and I know he was right because of other symptoms he was able to help with. This one was not fixable). I spent decades getting terrible advice from MDs.

Women often have to urinate a lot because the uterus can flop around and because organs can sag if muscle tone isn't good, putting a lot of weight on the bladder. Men who have enlarged prostates have to urinate a lot. Aging kidneys will of course have an effect.

So there's just 4 out of several reasons. I doubt it's vitamin D.

But as I am so fond of saying, NO SYMPTOM means much without the whole patient! We know nothing about you - agesexweightfamilyandpersonalhistorygeneralhealth!
