Re: --Blood in Our Stool--

Blood in the stool can occur for various reasons such as hemorrhoids, ulcerative colitis, upper GI bleeds, etc. Does acid cause these? Generally no. The only time acid would play a role is in the case of using non-steroidal anti-inflammatory drugs (NSAIDs). Because these drugs interfere with the production of the stomach's protective lining the NSAIDs allow direct attack of the stomach wall by stomach acid. Ulcerative colitis and hemorrhoids have nothing to do with acidity.

Not all acids adversely affect tissues. For example lactic and acetic acids are found in various parts of the body where they serve beneficial purposes. Likewise citric and malic acids are essential in the formation of adenosine triphosphate (ATP), which provides energy to the cells and allows them to function properly.
