9. Vitamin B1 is also known as thiamine. A severe deficiency of this vitamin can lead to which disease?
From Quiz Vital Vitamins
Answer:
Beriberi
Thiamine is found in many different food products, including brown rice, pork, oatmeal, liver and eggs. As with all vitamins of the B-complex, it is soluble in water, and thus not stored in large quantities in the body. An excess of vitamin B1 is quite rare, as normal urination gets rid of superfluous vitamin B.
Severe lack of vitamin B1 may cause beriberi or the Wernicke-Korsakov-syndrome. Beriberi is a serious disease which can manifest itself in two different forms. The "wet" beriberi affects the cardiovascular system and can be recognized by very fast hart beat, shortness of breath and swelling of the legs. The "dry" form of the disease attacks the neural system, causing, for instance, numbness in the limbs, difficulty controlling leg movements, pain and confusion.
Wernicke-Korsakov-syndrome is similar to the effects of prolonged alcohol abuse: confusion, memory loss or false memories, problems with the eyesight, intellectual dysfunctions (such as a slurred speech, problems with routine actions, or difficulty trusting one's senses).
On the other hand there have been cases of an excess of vitamin B1, with symptoms such as drowsiness or relaxation of the muscles.
Glossitis is an infection of the tongue and may be provoked by lack of vitamin B2.
Dermatitis (skin infection) may be caused by lack of vitamin B7.
Rickets is a condition of young children that don't receive enough vitamin D. Its symptoms are weak bones, slow growth, perhaps even skeleton deformities.
