The deficiency of vitamin E is very rare. But still it may cause haemolytic anaemia.
Vitamin A deficiency is a lack of vitamin A in humans. It is common in developing countries but rarely seen in developed countries. Night blindness is one of the first signs of vitamin A deficiency. Xerophthalmia and complete blindness can also occur since Vitamin A has a major role in phototransduction. Approximately 250,000 to 500,000 malnourished children in the developing world go blind each year from a deficiency of vitamin A, approximately half of which die within a year of becoming blind. The United Nations Special Session on Children in 2002 set the elimination of vitamin A deficiency by 2010. The prevalence of night blindness due to vitamin A deficiency is also high among pregnant women in many developing countries. Vitamin A deficiency also contributes to maternal mortality and other poor outcomes in pregnancy and lactation.[1][2][3][4]Vitamin A deficiency also diminishes the ability to fight infections. In countries where children are notimmunized, infectious disease like measles have higher fatality rates. As elucidated by Dr. Alfred Sommer, even mild, subclinical deficiency can also be a problem, as it may increase children's risk of developing respiratory and diarrheal infections, decrease growth rate, slow bone development, and decrease likelihood of survival from serious illness.Vitamin A deficiency is estimated to affect approximately one third of children under the age of five around the world.[5] It is estimated to claim the lives of 670,000 children under five annually.[6]Approximately 250,000-500,000 children in developing countries become blind each year owing to vitamin A deficiency, with the highest prevalence in Southeast Asia and Africa. According to the World Health Organization (WHO), vitamin A deficiency is under control in the United States, but in developing countries vitamin A deficiency is a significant concern.
All the vitamins are necessary for human health, and if you are not getting enough of any particular vitamin, there is a disease that will result. Lack of vitamin C causes scurvy, lack of vitamin B causes beri-beri, lack of vitamin D causes rickets, lack of vitamin A harms vision and in extreme cases causes blindness. Vitamin E is not as critical, but a deficiency of it will still have a harmful effect on health.
A deficiency in vitamin D, responsible for regulating the concentration of calcium and phosphates in the blood, leads to reduction in bone mineral density. In childrens bones, which are still growing, this leads to rickets. In some cases rickets can be caused by calcium deficiency.
A malnourished person is usually very thin (although there are certainly cases of people who aren't thin, but still have nutritional deficiencies) and such a person may have any number of nutritional deficiency diseases. A person with a vitamin D deficiency can have a disease called rickets, which results in malformed bones. A vitamin C deficiency causes scurvy, which has many symptoms including bleeding gums. Vitamin B deficiencies cause beri-beri. Iron deficiencies cause anemia. Iodine deficiencies cause goiter (enlarged thyroid gland) etc.
If you have a health problem that requires you to take vitamin B12 sublingually, it is unlikely that swallowing the same dose will be effective. Vitamin B12 requires the presence of intrinsic factor for proper digestion in the stomach. That's why it's given IM or SL instead in most cases of deficiency.
Marasmus is generally the result of lack of carbohydrates and proteins; and Kwashiorkor is only protein deficiency. Marasmus is severe malnutrition characterized by carbohydrates and protein deficiency. Kwashiorkor is a protein deficiency .
The "standard" answer is that you will get rickets if you are a child. If you are an adult you will get osteomalacia or osteoporosis. But researchers are now finding that vitamin D seems to be responsible for a whole host of functions that were never appreciated until recently. Vitamin D's immune functions and regulation of both inflammation and cell death means that researchers are beginning to believe that not getting enough vitamin D may play a role in preventing: colds and flu autoimmune disorders Multiple Sclerosis periodontal disease and even many different cancers.
