sköldbrusk

Sköldbrusk, also known as scurvy, is a disease caused by a deficiency in vitamin C, leading to symptoms such as fatigue, weakness, and skin lesions. The term "sköldbrusk" is derived from the Swedish words "sköld" meaning shield, and "brusk" meaning rash, referring to the characteristic skin lesions that appear on the extremities. The disease was first recognized in the 18th century and is now preventable through adequate dietary intake of vitamin C or supplementation.

The primary cause of sköldbrusk is a lack of vitamin C in the diet, which is essential for the production of collagen, a protein crucial for the structure and function of connective tissues. Without sufficient vitamin C, the body cannot produce enough collagen, leading to the breakdown of these tissues and the development of symptoms.

Symptoms of sköldbrusk typically begin to appear after a period of several weeks to a few months of inadequate vitamin C intake. The most common symptoms include fatigue, weakness, joint pain, and skin lesions. The skin lesions, known as petechiae, are small, red or purple spots that appear on the skin, particularly on the extremities. In severe cases, the disease can progress to more serious complications, including anemia, gastrointestinal bleeding, and even death.

Prevention and treatment of sköldbrusk are relatively straightforward. Adequate dietary intake of vitamin C, either through fresh fruits and vegetables or supplementation, can prevent the development of the disease. In cases where sköldbrusk has already developed, treatment typically involves the administration of high doses of vitamin C to replenish the body's stores and alleviate symptoms. In severe cases, hospitalization and intravenous vitamin C therapy may be required.
