Beware Of Anemia And Dementia Due To Lack Of Vitamin B12! Jiang Kunjun Warns: 3 Kinds Of People Are Most Likely To Lack B12

Vitamin B12 is one of the most important nutrients in the human body. It has many functions, including helping metabolism, stabilizing nerves, participating in red blood cell and DNA synthesis, etc. Once the body lacks vitamin B12, it may cause various health crises.

Deficiency of vitamin B12, anemia, depression, and dementia may come to you.

Jiang Kunjun, deputy director of research at Minsheng Hospital, pointed out that lack of vitamin B12 may lead to nerve damage and instability, and may cause tingling in the hands and feet, feeling like being pricked by acupuncture; Because vitamin B12 is involved in the synthesis of red blood cells, if it is lacking, it may also lead to anemia, not only the skin looks pale, but also symptoms such as fast heartbeat, easy wheezing when walking, and oral ulcers.

In addition, studies have pointed out that vitamin B12 deficiency is related to depression and bipolar disorder. Jiang Kunjun explained that because vitamin B12 will decompose "homocysteine" in the brain, if this substance is excessively accumulated in the brain, there will be emotional disorders such as irritability and depression.

What worries everyone the most is that lack of vitamin B12 will reduce the oxygen-carrying capacity of the brain, lead to difficulty in reasoning or loss of fragmented memory, and lead to cognitive impairment in the brain, which may lead to dementia and Parkinson's disease in the long-term.

3 types of people are most likely to be deficient in vitamin B12

Jiang Kunjun reminded that there are 3 ethnic groups that are likely to face vitamin B12 deficiency, so be sure to pay more attention:

1. Vegetarians

Vitamin B12 cannot be produced by the human body, and must rely on external microorganisms to synthesize it.Most of them need to be obtained from animal sources, so vegetarians are more likely to be deficient in vitamin B12.

2. Those who have undergone gastric surgery

After you eat food containing vitamin B12, you need to rely on two important roles in the body to absorb it smoothly, that is, gastric acid and intrinsic factors secreted by the stomach. If you have had stomach surgery or gastrectomy, you may be deficient in vitamin B12 because your stomach cannot absorb it smoothly.

3. The elderly

Similarly, the elderly often have problems with poor gastrointestinal function, and their absorption of vitamin B12 is naturally greatly reduced, so they are prone to vitamin B12 deficiency.
