You may be able to treat iron deficiency and decrease RLS symptoms by eating more iron-rich foods, such as: red meat; liver; spinach and other dark leafy greens; dried fruit; poultry; pork; seafood; iron-fortified cereals; beans; Eating foods rich in vitamin C along with iron-rich foods can help your body absorb iron better.
Parathyroid hormone (PTH) stimulates uptake of calcium into the bones (1) (and therefore osteoblast apoptosis (2)) and deportation of calcium from the bones (23), and inhibits excretion of calcium, generally increasing a low blood-calcium level. Low levels of PTH prevent bone loss.
Secretion of antidiuretic hormone is also stimulated by decreases in blood pressure and volume, conditions sensed by stretch receptors in the heart and large arteries. Changes in blood pressure and volume are not nearly as sensitive a stimulator as increased osmolarity, but are nonetheless potent in severe conditions.
