I have suffered from heartburn for many years, IBS for a decade. Never any concern re my heartburn but it has increased significantly lately. Add to that a strong burning sensation lately in my abdomen especially when my IBS is acting up. I tried Zantac and it seemed to work. I was actually normal for about 10 days (no IBS symptoms) and felt great, but suddenly tonight it all started up again. I started with the Zantac again (for the heartburn (not the diaharrea), but how long can you stay on it? I found that a combination of calcium caltrate, metamucil and yogurt daily seemed to be the magic solution for the D, but not sure now with how I feel presently. Anyhow, will call the GI specialist or my GP as they have taken more blood tests and stool samples and am waiting for the results. I have an excellent attitude and lead a full active life, but I am frustrated because every time I think I have it beat, it starts up again! I know that is the 'nature of the beast', but is it possible that the IBS will ever disappear? several issues here, but am Is there a relationship between the D and the heartburn or are they two separate issues? However, when one seems to be bad, so does the other. I realize that I have raised several different issues here, but any comments or suggestions would be most appreciated.
