What does stomach acid do for me?
Two key benefits: absorption and protection. When food hits your stomach, it’s your stomach’s gastric acid that begins the breakdown of protein and most minerals with pepsin to prepare for the important absorption of key nutrients (like iron B12, Vit. D and MORE) in those foods for your health and well-being. It also helps knock out bad or dangerous bacteria.
Low stomach acid also leads to non-optimal levels of neurotransmitters/amino acids (chemicals which transmit signals from one cell to another and play a huge role in your health and well-being).
How hypothyroidism negatively affects your stomach acid levels
Just as hypothyroidism can result in the drying out of your skin and hair, it also seems to lower the levels of stomach acid in many thyroid patients, possibly by lowering your amount of parietel cells. The result? The absorption of important nutrients is reduced, and you can find yourself with non-optimal or low levels of iron, B12, Vitamin D and more. And you won’t have the protection you once had against bad forms of bacteria, causing their over-growth (dysbiosis). Symptoms can include delayed excessive gas as that bacteria enters your intestine. (Long term antibiotic use can also cause the same overgrowth.)
