Calcium serves as a foundational element in preserving skeletal structural integrity and muscular functionality, while also participating in critical physiological processes such as neural transmission and blood coagulation. Its chronic deficiency, though frequently asymptomatic in early stages, poses a substantial risk to the body’s homeostatic balance. This condition is no longer confined to the elderly population, where absorption may be compromised due to age-related metabolic shifts, but is increasingly identified among middle-aged adults, adolescents, and even pediatric patients. This article provides a comprehensive examination of hypocalcemia, with particular emphasis on its clinical manifestations—including dermatological alterations—as well as the potential health consequences that may arise in the absence of timely and appropriate therapeutic measures.
There's a shortage of calcium
Calcium is a major extracellular cation. It performs a number of extremely important functions in the body, e.g. as a component of bones and teeth. It also acts as an activator of certain enzymes or as an essential element in the proper blood clotting process. A short period of deficiency is neither dangerous nor noticeable.
Calcium deficiency causes skin symptoms
In addition to the symptoms of the nervous or muscular system, there are also dermatological symptoms, such as fractures of the nails or hair, but above all skin dryness and even pelvic inflammation. As a result, itching of the skin and frequent rashes, even of an allergic nature, become an uncommon problem.
Effects of calcium deficiency
Because more than 99% of this macronutrient is stored in the bones, in times of shortage, it is the neural system that is the backup source. As a result, bone mass decreases and bones become softened (osteomalacia). This chronic and untreated condition significantly weakens the strength of the bones leading to their frequent bruising and osteoporosis. Additionally, there are symptoms from the nervous system.
