vitamin d deficiency hypertension

Vitamin D deficiency is associated with hypertension, meaning that a lack of vitamin D may lead to elevated blood pressure. Typically, vitamin D not only sustains bone health but also offers protection to the cardiovascular system.

Further analysis indicates that vitamin D influences the renin-angiotensin system, which in turn regulates blood pressure. When vitamin D levels are low, renin activity increases, and angiotensin II levels rise, triggering vasoconstriction and a subsequent increase in blood pressure. Moreover, vitamin D can mitigate the proliferation and contraction of vascular smooth muscle cells by inhibiting the rise in intracellular calcium ion concentration, thereby reducing peripheral vascular resistance and aiding in blood pressure control. Research suggests that for every 1ng/mL decrease in vitamin D levels, the risk of hypertension rises by 11%. Consequently, supplementing with an adequate amount of vitamin D may help individuals with vitamin D deficiency to lower their risk of hypertension.

To address vitamin D deficiency-related hypertension, it is important to increase outdoor activities and sun exposure in daily life to facilitate the skin's synthesis of vitamin D. Additionally, consuming foods rich in vitamin D, such as fish, egg yolks, and dairy products, is advisable. For those who have developed symptoms of hypertension, it is crucial to seek medical attention promptly and to follow a treatment plan under a physician's supervision, rather than self-medicating without guidance.
