Vitamin deficiencies: causes and symptoms

Most often the lack of vitamins is due to an unbalanced diet. For example, people who have adopted a vegetarian diet are prone to vitamin B12 and vitamin D deficiencies. Many of the symptoms, which are attributed to other conditions, are determined by vitamin deficiencies. In the following, we present the causes of vitamin deficiency and the signs and symptoms of each type.

The most common causes of vitamin deficiency

Most often, the lack of certain vitamins is the result of an unbalanced diet. For instance, people who eat a vegetarian diet are prone to vitamin B12 and vitamin D deficiency. Similarly, women on a slimming diet face severe deficiencies in certain vitamins (notably vitamins B, C, D, and E) and require dietary supplements. The thermal cooking of food can destroy a significant amount of the vitamins found in some foods. Another common cause that can lead to chronic and overall vitamin deficiency is alcohol consumption. There are also a number of diseases that can be doubled by vitamin deficiencies, such as diseases affecting intestinal transit (biliary, pancreatic, and inflammatory bowel diseases). Among the categories of people most prone to the occurrence of vitamin deficiencies and their symptoms are people with low immunity, the elderly and pregnant women.
