 What Is Geographic Tongue?

[dropcap]G eographic tongue is a painful alteration in tongue tissue that is characteristic of riboflavin (vitamin B2) deficiency.1

Q: How does the tongue surface appear?

A: Areas of inflamed tissue with flattened papillae develop among areas of normal tissue, giving a map-like appearance to the tongue surface. There are often swollen papillae that hurt or sting, such as is seen in the photo to the left.

A diet that does not provide adequate amounts of riboflavin and any condition that 1) interferes with riboflavin absorption from the gut, 2) depletes the vitamin from the body, 3) overuses the vitamin in the body, or 4) adversely affects its use in the body will result in riboflavin deficiency causing geographic tongue.

Riboflavin is essential for converting foodstuffs into energy, maintaining the normal lifespan of red blood cells and maintaining healthy skin, eyes, hair, and nervous system. Riboflavin is converted into its active forms, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). These enzymes are primarily involved as co-factors in oxidation reduction reactions that are essential for cellular energy production and respiration.

Riboflavin is required for the conversion of pyridoxine (vitamin B6) to its functional form and the production of niacin (vitamin B3) from the amino acid tryptophan. Riboflavin has a role in antioxidant status by activating glutathione reductase, which regenerates used glutathione, a powerful antioxidant.

Respiratory infection, exercise, certain diseases, drugs and hormones can adversely influence riboflavin status.2 Stress is a major depleter of riboflavin.

Vitamin B2 (Riboflavin) Deficiency

What Is Riboflavin?

[dropcap]R[/dropcap]iboflavin, also called vitamin B2, is fundamentally required for the breakdown of carbohydrates, amino acids, and fats in metabolism, enables oxygen to be used by cells, and acts as a component of more than a dozen enzymes involved in energy production and use.

Some enzymes needing riboflavin also require magnesium to properly function.

In other activities, riboflavin is required for healthy cardiovascular and nervous systems, eye health, and supports antioxidant protection.  Functions are more fully described below.

Urinary excretion of riboflavin cannot be detected when vitamin intake is below the required levels. On the other hand, when intake exceeds saturation in the body, the vitamin and/or its metabolites are actively excreted into urine to prevent excessive toxicity of the vitamins.1

There is no specific name for riboflavin deficiency disease.

What Is Tetany?

[dropcap]T etany is a painful feature of low blood calcium or low blood magnesium causing hyperexcitability of all nerves which in turn stimulates involuntary sudden, intermittent and repetitious tonic spasms of muscles. Tonic spasms are steady rather than jerky.

Causes include low function of the parathyroid glands which regulate calcium blood levels, vitamin D deficiency which inhibits calcium absorption from the gut that leads to calcium deficiency, and alkalosis.

In alkalosis, the chemical pH (acid/alkaline measure) of blood is too high, or alkaline, which inhibits adequate free calcium ions from being available for cell use.

Q: Why do low blood levels of calcium or magnesium cause muscles to spasm?

A: Calcium controls the readiness of muscle to respond to nerve stimulation. In muscle action, calcium and magnesium are minerals that oppose each other. Calcium allows a muscle to contract while magnesium allows it to relax. Inadequate levels of these opposing minerals affect the ability of muscles to properly function.

A simple test for tetany is called Trouseau’s named after the doctor who developed it. A blood pressure cuff is placed on an upper arm as usual and pumped up to a pressure sufficient to stop blood flow.  The pressure must be held for 3 minutes. A positive result is shown in the above photo of carpopedal spasm: the wrist and hand flexes inward while the fingers extend (opposite of wrist and hand) and the thumb goes against the palm.

What Is Hyperprolactinemia?

[dropcap]H yperprolactinemia is an excess secretion of prolactin hormone causing an elevated blood level that is characterized by its effects on reproduction: in females causing  amenorrhea and in males causing reduced sexual potency.

Q: What is prolactin?

A: Prolactin is a hormone produced by the the anterior pituitary gland that is transported by the bloodstream to stimulate androgen hormone production in male and estrogen hormone production in female sex glands. However, too much prolactin inhibits hormone production of estrogen in women and testosterone in men.

In pregnant females upon delivery of a baby, prolactin stimulates breast development and milk production for the purpose of feeding the infant. Sucking by the infant stimulates the release of prolactin which keeps the milk supply adequate.

Prolactin also promotes autoimmune mechanisms. Prolactin interferes specifically with B cell tolerance induction, enhances proliferative response to antigens and mitogens and increases the production of immune globulins, cytokines and autoantibodies.1

Other conditions that can stimulate prolactin release include nutritional deficiencies, thyroid stimulating hormone (TSH) produced by the pituitary gland, stress, exercise, and anterior pituitary tumors.
