Often times we must take our health into our own hands, especially when it comes to the thyroid and metabolism. The thyroid, when not working properly, can cause a myriad of symptoms that can be wholly debilitating and destroy quality of life.
B-12 seems a simple fix if one is feeling depressed with little hormonal reserves to take up the slack. Most who are hypothyroid are lacking in B-12 along with a number of other vitamins--especially iron.
Hypothyroidism itself causes systems in the body to slow down. That includes stomach acid. Naturally, with age, we have less stomach acid, but hypothyroidism exacerbates the problem.
We can no longer wait on doctors to "get it." If we did, many of us wouldn't be here...we'd be locked up somewhere banging our heads against a wall. Truly a horrible shame, especially in light of the fact that we can change most things about our thyroids ourselves: vitamins and nutrients!
If our stomach acid is too low and not allowing us to absorb the nutrients and vitamins of the foods and supplements we ingest (as well as our thyroid medications), then we can replace that acid ourselves. Research is the trick!
We must use our heads so we can figure things out for ourselves. Doing such has certainly saved my life. Doctors will never know our bodies as we do. With knowledge and research, we truly can become our own best medicine.
I can honestly say I feel you deep in my heart. It is a shame that the vast majority of doctors have no clue as to how the endocrine system works...that includes endocrinologists! Nothing is ever as simple as they make it out to be.
Know that you can be well when you either find the right doctor for your problems (the one you have is not sufficient), or you decide that you are going to figure things out for yourself. Blood tests and lab work can be ordered online (at least in the U.S.). I hope that is available to you as well.
