The malfunctioning of the bodies own immune system is in a way not a malfunctioning at all. As we lose vascularity because of dehydration, calcium buildup, too much carbs, not enough exercise, etc. we also lose tissue health. As cells and tissue loses this vital blood flow(bringing nutrients and removing toxins), then the cells no longer have their integrity. Just like dead cells are sloughed off our skin and alimentary tract, the white blood cells and immune system try to remove these weak or dead cells from the tissues. Not only are their too many weak or dead cells that shouldn’t be their in the first place, but the weakened blood flow to the area also slows or stops the removal, creating an intermittent but never-ending process. By slowly adopting better eating habits and health habits, though, this effects is greatly lessened and eventually back to healthy level.
Keep in mind that the first sign of blood flow returning to an area is some redness, tenderness and inflammation. Some of these symptoms are normal and to be expected. As blood flow stays from a healthy diet, low carbs, more water, good fish oils and some exercise and sun, then the tissue moves beyond inflamed to healthier over time.
