Health Condition(s) or Problem(s) studied
Interstitial cystitis
Intervention(s)
The patients will be intervened with hydrogen dissolution water group (hydrogen group) 200ml every three times in a day in 2 months (56days).

Secondary Outcome(s)
1) Changes of the Symptom Score in Interstitial Cystitis Symptom Index(ICSI)
2) Changes of the Problem Score in Interstitial Cystitis Problem Index(ICPI)
3) An Average frequency of urination per day
