Health in old age depends largely on the balance of trace elements in the body. Irish scientists have found that a deficiency in just one vitamin can significantly worsen the quality of life of pensioners and almost double the risk of developing severe depression.
This is reported by specialized medical resources, citing the results of a study by Irish scientists.
We are talking about vitamin B12, a key element that plays a fundamental role in the functioning of the body. It is necessary for the formation of red blood cells, the normal functioning of the central nervous system, and DNA synthesis. Without sufficient levels of this vitamin, a chain of pathological changes is triggered that can lead to serious consequences.
According to the study, if B12 deficiency is not detected and treated within four years, the risk of developing clinical depression in older people increases by 51%. However, vitamin deficiency is often masked as normal signs of aging, which is why it goes unnoticed for a long time.
The first symptoms include chronic fatigue, general weakness, digestive disorders, decreased appetite, and unexplained weight loss. Later, neurological disorders may appear: memory problems, spatial disorientation, and decreased cognitive functions. In severe cases, this can progress to dementia.
One of the most dangerous physiological consequences of B12 deficiency is anemia. It often occurs against the background of a lack of other B vitamins, in particular folic acid. Doctors emphasize: timely diagnosis and correction of the deficiency help prevent irreversible changes in the brain and nervous tissues.
Older people are a particularly vulnerable group. The reason is age-related changes in the digestive system. Over the years, the production of hydrochloric acid in the stomach, which is necessary for the breakdown of proteins and the release of vitamin B12 from food, decreases. As a result, the body absorbs this important microelement worse, even if the diet remains balanced.
Experts advise older people to undergo regular examinations, monitor the level of vitamin B12 in the blood, and, if necessary, adjust their diet or take supplements as recommended by a doctor.
