It can also refer to how one absorbs these molecules after they are broken down, and to results of incomplete digestion that leads to diarrhea and constipation. All of these functions can be influenced by mercury. Let's start in the mouth. The act of chewing stimulates the release of saliva which contains certain enzymes that initiate carbohydrate metabolism. As chewing stimulates the release of salivary enzymes, it simultaneously stimulates the release of mercury from your fillings.
Mercury mixes with the food and goes down the digestive tract with it.
In the stomach mercury from fillings can mix with hydrochloric acid and produce mercuric chloride. This chemical can damage the stomach lining, paving the way for nervous stomach and ulcers in those people genetically predisposed to those conditions. There are multiple types of bacteria in the stomach and intestinal tract that aid in our digestion. These are the bacteria we try to fortify in our system when we eat buttermilk, yoghurt, and take acidophilus capsules from the drug store. Mercury can kill many of these bacteria just by touching them.
