Iron is not a vitamin, but a mineral. If a person has low iron levels in the blood, it may cause fatigue and other symptoms, especially in women.
These are all summed generalisations Vitamin C deficiencies leads to scurvy Iron deficiencies leads to fatigue Vitamin D deficiencies lead to a bad immune system Protein deficiencies lead to bad muscle growth and weakness Fibre deficiencies leads to clogged up bowels, which cause constipation Vitamin B deficiencies lead to nervous system damage, acne, depression, birth defects and weight lost Vitamin A deficiencies will lead to possible blindness, since it affects the retina, and abnormal bone growth Sugar deficiencies lead to lack of energy, possibly, not sure on that one I hope I've covered the common ones!

defency in Vitamin A is leading cause of blindness worldwide
The most important micronutrient deficiencies include iron, vitamin A, iodine, and folate. Iron deficiency can lead to anemia, causing fatigue and impaired cognitive function. Vitamin A deficiency can result in vision problems and increased susceptibility to infections, while iodine deficiency can cause thyroid disorders and developmental issues. Folate deficiency is particularly concerning during pregnancy, as it can lead to neural tube defects in developing fetuses.
A person who does not get enough essential vitamins can experience a range of health issues, depending on which vitamins are lacking. For example, a deficiency in vitamin C can lead to scurvy, characterized by fatigue and bleeding gums, while a lack of vitamin D can result in weakened bones and increased risk of fractures. Additionally, vitamin B deficiencies can cause fatigue, neurological problems, and anemia. Overall, insufficient vitamin intake can compromise the immune system, hinder growth, and negatively impact overall well-being.
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.
Deficiencies in vitamin A can lead to vision problems, particularly night blindness, and can compromise immune function. Zinc deficiency may result in impaired immune response, delayed wound healing, and hair loss. Iron deficiency is primarily associated with anemia, leading to fatigue and weakened immunity, while iodine deficiency can cause goiter, developmental delays, and thyroid dysfunction. Collectively, these deficiencies can significantly impact overall health and development.
Deficiencies of fat-soluble vitamins (A, D, E, K) can occur in individuals with malabsorption disorders, restricted diets, or certain medical conditions that affect fat absorption. Symptoms vary by vitamin but can include night blindness (vitamin A), weakened bones (vitamin D), neurological issues (vitamin E), and impaired blood clotting (vitamin K). Proper diagnosis and treatment by a healthcare provider are essential to address these deficiencies.
Pellagra is a Vitamin B3 (Niacin) deficiency disease. It is caused by severe and prolonged deficiency of Vitamin B3. Symptoms are bilateral dermatitis, dementia, and diarrhea. A prolonged and severe niacin deficiency may cause depression and neurasthenia (weakening of muscles).A deficiency in Vitamin B3 can cause depression, memory loss, canker sores and fatigue.
New Entry: Deficiencies in Vitamin A are more widespread in the world than any other vitamin and cause up to 80,000 people (mostly children) to become blind each year.Old Entry: Well-known human vitamin deficiencies involve thiamine (B1)- (beriberi), niacin (B3)- (pellagra), vitamin C (scurvy) and vitamin D (rickets).Vitamin K causes bleeding diathesis.Vitamin B6 causes anemia.Riboflavin (B2) causes ariboflavinosis.Vitamin A causes night blindness and keratomalacia.According to WHO Micronutrient deficiencies are:- Iodine deficiency disorders- Vitamin A deficiency- Iron deficiency anaemiaIn the light of the above facts, I select (item D) Vitamin A. * 1 year ago http://en.wikipedia.org/wiki/Vitamin#Hum...http://www.who.int/nutrition/topics/micr...
