Can occur due to inadequate intake or impaired intestinal absorption of magnesium. Low magnesium (hypomagnesemia) is often associated with low calcium (hypocalcemia) and low potassium (hypokalemia). Deficiency of magnesium causes increased irritability of the nervous system with tetany (spasms of the hands and feet, muscular twitching and cramps, spasm of the larynx, etc.). According to the National Academy of Sciences, the Recommended Dietary Allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements is 350 milligrams daily, in addition to the magnesium from food and water.
- Magnesium excess
Persons with impaired kidney function should be especially careful about their magnesium intake because they can accumulate magnesium, a dangerous situation. According to the National Academy of Sciences, the Recommended Dietary Allowances of magnesium are 420 milligrams per day for men and 320 milligrams per day for women. The upper limit of magnesium as supplements […]
- Magnesium sulfate
A remarkably versatile compound administered intramuscularly and intravenously as an anticonvulsant and as a tocolytic agent (to halt premature labor), taken by mouth as a fast-acting laxative, and applied locally as an anti-inflammatory. Informally called mag sulfate. Also known as Epsom salt.
- Magnet therapy
Magnetic therapy, also called magnetic field therapy and bioenergy therapy, is an alternative therapy that uses magnets of varying sizes and strengths that are placed on the body to relieve pain and treat disease. Thin metal magnets are attached to the body alone or in groups. They can be worn as bracelets or necklaces, attached […]
- Magnetic resonance elastography
An imaging technique used to measure the elasticity of tissue by gently shaking the tissue in a magnetic resonance imaging (MRI) machine. The technique employs standard MRI equipment with a few modifications and a vibrating metal plate placed on the skin. Magnetic resonance elastography (MRE) works by measuring the wavelength of the vibrations sent through […]
- Magnetic resonance imaging
A procedure that uses magnetism, radio waves, and a computer to create pictures of areas inside the body. Abbreviated MRI. An MRI is painless and has the advantage of avoiding x-ray radiation exposure. There are no known risks of an MRI. The benefits of an MRI relate to its precise accuracy in detecting structural abnormalities […]
