what are the symptoms of either?

Hi im in need of a little assistance here before I have time to get to the doctor later this week.

Im 21 years old, male, and about 30 pounds overweight. Despite being overweight for most of my life i've always maintained very good health. Recently, however, ive began to feel like there may be something wrong.

Within the past 6-8 months ive had random spurts of experiencing frequent urination. Its off and on, and has occurred maybe 10 times in the past 6 months or so. When it comes, it tends to only last for a few days. During this time I get extremely and frequent sensations to go to the bathroom. Going to the bathroom is normal and doesnt hurt or anything, but its just weird to have to go ALL the time. Yesterday, for instance, I did drink a good amount of iced tea for dinner (4-5 full cups) but shortly after dinner I got an extreme and sudden urge to go. I ended up getting that urge 2 other times within the next half hour, and one more about an hour after that.Going to the restroom 4 times within 90 minutes following a meal seems very unusual to me.

I do have a few of the other symptoms of Type 1 Diabetes to go with frequent urination, so im thinking it could potentially be that. Or something related to an enlarged prostate maybe?

Any help or ideas you could provide is greatly appreciated.

Thanks!

ok so here lately ive had the symptoms of BHP (enlarged prostate) how i urinate and all...is it possible i could have it this young?
