Parathyroid hormone (or parathyrin) formed parathyroid glands. They look like four small endocrine gland located on the rear surface of the thyroid gland. Parathyrin responsible for regulating calcium and phosphorus metabolism.
Description and norm
Parathyrin content in the body is regulated depending on the amount of calcium in the blood. By reducing the level of calcium parathyrin hormone produced stronger. It stimulates cells whose task - to destroy the bone, so that the amount of calcium in the body increases. Also, the hormone reduces the excretion of calcium in urine and stimulates the excretion of phosphorus.
The amount of the hormone in the body depends on the time of day. Its maximum value is manifested in 14-16 hours, minimum - at 8 am. At the level also affects the blood plasma. In a healthy adult human hormone levels ranging from 1.6 to 6.9 pmol / L.
Parathyroid hormone and food
Lack parathyrin significantly reduces the amount of calcium in the blood. To normalize the hormone level, you need to consume foods that contain calcium in its composition. This essential trace element is part of the cell and tissue fluids, blood coagulation and helps to prevent the penetration of viruses and bacteria in cells.
The first thing that should be on your desk - nuts, seeds and legumes. It almonds, beans, peas, all kinds of beans, peas and lentils. Pay attention to soy products: tofu, cheese, milk and yogurt. Next - vegetables and fruits. Eat more of apricots, peaches, grapes, broccoli, cauliflower, radishes, do not forget about citrus. Eat fish and seafood. From meat - boiled chicken or roast beef. As seasonings use dill, rosemary, parsley, cinnamon and basil.
Larger amounts of the hormone leads to bone destruction, occurrence of osteoporosis (bone disease) and hyperparathyroidism (endocrine disease). The low number of parathyroid hormone is accompanied by a decrease in blood calcium levels. This causes the following states: neuromuscular excitability, alkalosis (increase alkalis in the body), and renal insufficiency. In severe shortage of cataracts may be hormone - clouding of the eye lens due to the reduction of calcium deposits.
