I'm an 18 year old male and I take pepto-bismol for nausea and dyspepsia. It relieves these symptoms for a while and does a good job. I just want to ask this: What stomach conditions can be treated with pepto-bismol? And more importantly, what stomach conditions does pepto-bismol fail to treat/doesn't provide very much relief for? I am just trying to rule conditions out so that I can figure out what condition I might have. I am seeing a doctor, but it is a very slow process trying to figure out what I have. I have had this affliction since May and I am finally getting a fluoroscopy/upper GI in mid-September.
