I'm 32/male - 6' - 146 pounds. i've begun having a strong sudden urge to have a bm in the morning. it happens every morning when i open my eyes. more of a very strong pressure than a real pain, then don't usually go again until next morning.

IBS: This urgent morning need for a bowel movement can be seen in the irritable bowel syndrome. This is more likely than intolerance to foods containing lactose, fructans or gluten since you don't have more urgent type bowel movements after the morning one. Try to determine if you are intolerant to certain foods. Taking a nighttime dose of a medication like dicyclomine may obviate this morning problem.
