甲状旁腺功能亢进刺激小肠钙吸收

rathyroidism is a medical condition where the parathyroid glands produce excess parathyroid hormone (PTH). This hormone plays a vital role in regulating calcium balance in the body. Elevated PTH levels stimulate the small intestine to absorb more dietary calcium through increased activation of vitamin D. This enhanced absorption can lead to higher calcium levels in the blood, a condition known as hypercalcemia. Over time, this process may affect bone density, kidney function, and overall metabolic health. The concept highlights the direct link between parathyroid function and digestive calcium uptake.
