dominance, which is the root cause of endometriosis, has also been linked
to hypothyroidism or thyroid dysfunction. Both Dr. John Lee and Dr. Elizabeth
Smith have seen successful restoration of the thyroid by use of natural
progesterone and avoiding xenoestrogens and phytoestrogens
Why Do Hypothyroid Symptoms Disappear with Progesterone?
Dr. John Lee believes that thyroid hormone and estrogen actually oppose
each other. Estrogen causes food to be stored as fat. While the thyroid
hormone causes fat to be burned as energy. Patients with normal thyroid
hormone levels measured by laboratory tests have symptoms that suggest
they have hypothyroidism. When these same patients are given progesterone
which is known to oppose estrogen their hypothyroid symptoms ceased. This
implies that too much estrogen in the body, estrogen dominance, interferes
with thyroid hormone action.
