IgA nephropathy is the most common disease affecting the kidneys in which the immune system is the underlying culprit (as opposed to diabetes or high blood pressure, the two most common causes of kidney problems overall). Conventional medicine has surprisingly few options for this condition, which is unfortunate as research is clear about how to deal with almost all cases of this without drugs (or minimal drugs).
IgA nephropathy is actually not directly a kidney disease. Instead, people with this condition make a type of antibody (type A, or immunoglobulin A, thus the IgA part of the name) in excess in other areas of the body, primarily the respiratory and digestive tracts. Unfortunately, genetic problems means that type 1 of IgA don't really work in people with this condition. More and more antibodies get made as the body tries to respond to pollen, microbes, or food antigens. These build up in the blood, and inadvertently get gummed up in the kidneys, which of course have a major function of filtering the blood.
Strangely, conventional medical providers often give no therapy for this condition other than certain blood pressure medications that protect the kidneys (ACE inhibitors or angiotensin receptor blockers). Occasionally they use immunosuppressive drugs, but these have serious side effects and their benefits are questionable (given that they don't treat the cause of why the immune system is overreacting and making all these ineffective antibodies). Ultimately, patients end up on dialysis or get transplants if the disease progresses.
But we know what triggers the antibody production outside the kidneys, and this is very treatable. Dr. Yarnell works with you to identify what your individual triggers are, and to eliminate or reduce exposure to them. He couples this with various herbal agents that help heal the damage the buildup of the antibodies in the kidneys may have caused, including scarring in the worst cases. This is one of the areas in which Dr. Yarnell has seen the most success for people who didn't get any good options from their conventional medical providers.
