Anatomy of Hair. A diagram of hair anatomy appears relatively straightforward, but it's actually one of the most complicated structures in the body.

How hypothyroidism negatively affects your stomach acid levels.

Other factors, such as an H. pylori infection, can also contribute to your acid reflux.
