Vitamin Deficiency: Symptoms, Diagnosis, and Treatment
Vitamins and its Deficiency
Vitamins are organic compounds that are essential for the normal functioning of human body. They are required in small amounts and cannot be synthesized by the body in sufficient quantities, so they must be obtained through the diet or through supplements. Vitamins play important roles in various biological processes, such as energy metabolism, cell growth and differentiation, immune function, vision, and bone health. There are 13 essential vitamins, which are classified as either water-soluble or fat-soluble based on their solubility in water and fats, respectively.
- Water-soluble vitamins include B vitamins and vit C. These vitamins are not stored in the body to a significant extent and are excreted in urine if consumed in excess. Therefore, a regular intake of water-soluble vitamins is necessary to maintain their lives in the body.
Water-soluble vitamins include:
- Vitamin B1 (thiamine)
- Vitamin B2 (riboflavin)
- Vitamin B3 (niacin)
- Vitamin B5 (pantothenic acid)
- Vitamin B6 (pyridoxine)
- Vitamin B7 (biotin)
- Vitamin B9 (folate & folic acid)
- Vitamin B12 (cobalamin)
- Vitamin C (ascorbic acid)
B vitamins play important roles in energy metabolism, DNA synthesis, and the nervous system. Deficiency of B vitamins can cause a variety of symptoms, such as dermatitis, diarrhoea, dementia, glossitis, anaemia, and birth defects. B vitamins are found in a variety of foods, such as meat, fish, poultry, eggs, dairy products, whole grains, legumes, nuts and seeds.
