bdcc, I do not have ulcers. I have been skewered like a roasted pig on multiple occasions by the GI doc.
I have GERD and a hiatal hernia. As far as HCL, I think it splits down the middle. I believe based on experience and what I've read, that some people do have low stomach acid and can benefit from HCL. Those people see results where other meds/supplements fail and sing the praises of it.
Poloquin's suggestion of doing a test is a good idea though. I just don't like the way some other sites claim it's the cure-all for stomach problems when, in fact, some people simply produce too much acid and won't benefit from HCL. For me, it was not good. Same for spearmint. While it is great for eso****eal sparms, it is terrible for heartburn, yet included in many heartburn remedies.
So, it goes something like this: I have a hiatal hernia which allows stomach acid into my eso****us and causes irritation of the LES. Betaine aggravated this condition. In addition, I produce too much stomach acid, which further aggravates things. Unfortunately, I am stuck with taking a PPI daily. Beleive me, I have tried to get off of them with no success. It's not just the rebound effect either, I just have a condition that necessitates them. In another thread, someone had gone to the ER and been prescribed PPI's for what sounded like a LES irritation. I advised them to run it for two weeks and get the heck off them asap or they might get stuck on them for life. Unfortunately, I feel doctors stick people on these things indefinitely all too often.
So, just wanted you to see the path I've taken with this because I believe it is very important for people to experiment and find out what works for them as well as not believe everything their doctor or homeopath tells them. Everyone is different and trial and error is the key.
Fortunately, I have been able to cut my PPI dose in half by including enzymes, probiotics, and ginger into my diet. The key for me has been to get it out of my stomach and into the small intestine asap and the aforementioned supps help. In addition, adding certain acidinc fruits (which once digested become alkalizing fruits) helps move things along as well...
