The neuromuscular symptoms of hypocalcemia are caused by a positive bathmotropic effect (i.e. increased responsiveness) due to the decreased interaction of calcium with sodium channels. Since calcium blocks sodium channels and inhibits depolarization of nerve and muscle fibers, reduced calcium lowers the threshold for depolarization. [ 7 ]
The Chvostek sign (/ ˈ k v ɒ s t ɪ k /) is a clinical sign that someone may have a low blood calcium level (a decreased serum calcium, called hypocalcemia).The Chvostek sign is the abnormal twitching of muscles that are activated (innervated) by the facial nerve (also known as Cranial Nerve Seven, or CNVII).

Over 40% of Americans do not consume enough calcium, which puts them at an increased risk of osteoporosis, bone fractures, and heart problems.
Disorders of calcium metabolism occur when the body has too little or too much calcium. The serum level of calcium is closely regulated within a fairly limited range in the human body. In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone , vitamin D and the calcium ...
Calcification of soft tissue (arteries, cartilage, heart valves, [1] [2] etc.) can be caused by vitamin K 2 deficiency or by poor calcium absorption due to a high calcium/vitamin D ratio. This can occur with or without a mineral imbalance. A common misconception is that calcification is caused by excess amount of calcium in diet. Dietary ...
But some health conditions and complications may also predispose you to having a calcium deficiency, including Celiac disease, Crohn’s disease, inflammatory bowel disease, vitamin D deficiency ...
Osteomalacia is a disease characterized by the softening of the bones caused by impaired bone metabolism primarily due to inadequate levels of available phosphate, calcium, and vitamin D, or because of resorption of calcium. The impairment of bone metabolism causes inadequate bone mineralization.
The Mayo Clinic diet, a program that adheres to this notion, was developed by medical professionals based on scientific research, so you can trust that this program is based on science, and not ...
