Since when is this happening? Is it increased frequency only or there is increased amount of urine also? Are you diabetic? Do you take alcohol? Have you delivered vaginally? If yes, how may times?
Your symptoms can be due to cystocele or urethrocele. This is because of the pelvic floor weakness. Read about the cystocele symptoms and other details;
Kegel exercise can benefit you. The diagnosis can be established by a physical examination. Read about Kegel exercise;
Other cause to look for are; urethral syndrome and interstitial cystitis. Diabetes too should be ruled out by glucose tolerance test and glycosylated estimation. Cystitis (bladder infection) also can give the same symptoms. To establish the diagnosis, a cystoscopy, urine culture, urodynamic studies may be needed.
