Which disorder involves inflammation of the tongue and may be caused by a deficiency in vitamin B?

The disorder that involves inflammation of the tongue is glossitis. Glossitis can manifest as swelling, color changes, or alterations in the surface texture of the tongue, and it is often associated with nutritional deficiencies, particularly deficiencies in vitamin B complex vitamins such as riboflavin, niacin, and cobalamin. These B vitamins are essential for various metabolic processes, including those that support the health of the mucous membranes in the mouth, including the tongue.

A deficiency in these vitamins can lead to inflammation and pain in the tongue, making it difficult for individuals to eat or speak comfortably. This condition can also be accompanied by other symptoms, such as changes in taste sensation or a smooth appearance on the tongue’s surface.

The other disorders mentioned do not directly relate to inflammation of the tongue or are associated with different symptoms and causes. Angular cheilitis typically involves inflammation of the corners of the mouth, scurvy is linked with vitamin C deficiency and presents primarily with skin and gum issues, and rickets is associated with vitamin D deficiency affecting bone health rather than the condition of the tongue.
