Deficiency of Vitamin D in Patients with Hypothyroidism and as a Related Risk Factor for Cardiovascular Disease

Hypothyroidism is a common health condition caused by a deficiency of the thyroxine hormone. The thyroxine hormone regulates the body's metabolic functions, and its deficiency can result in complications across various organs. Vitamin D deficiency is a worldwide concern that has health implications; it is regarded as a pandemic. It represents a global health concern primarily stemming from insufficient sunlight exposure. Hypothyroidism has been demonstrated to adversely affect the cardiovascular system, leading to issues such as vascular endothelial dysfunction, elevated systemic vascular resistance, dyslipidemia, and early-onset atherosclerosis beyond the typical symptoms.
