What might indicate a problem
Vitamin B12 (cobalamin) is needed for the normal functioning of the nervous system, as well as for the formation and maturation of red blood cells. With a deficiency of this substance, various symptoms begin to appear in the body, but the problem is that they are often confused with other conditions, told specialists from the UK National Health Service (NHS).
According to British doctors, a lack of B12 can cause anemia, which is accompanied by extreme fatigue, shortness of breath and weakness. However, there is another hidden sign of the disease that is often overlooked – the deterioration of cognitive functions, the experts shared the details. In this case, there are problems with memory and a decrease in mental abilities, they noted.
In addition, patients with vitamin deficiency complain of increased irritability and depressive disorders. Other signs of the condition include: pale yellow skin tone; an inflamed red tongue (glossitis); ulcers in the oral cavity; a feeling of crawling in different parts of the body (paresthesia); changes in gait; visual impairment.
In order to avoid vitamin deficiency, it is necessary to follow a proper diet. B12, in particular, is found in animal foods (meat, eggs and milk). Vitamin deficiency causes various disorders, including the nervous system.
