As is well known, the normal operation of the human body requires the support of many nutrients, including vitamins. In fact, within the large family of vitamins, there are many family members, such as vitamin B, vitamin C, and vitamin E, among which different types can be subdivided.
In vitamin B, there is a crucial vitamin that the human body does not require much, and that is vitamin B12. In daily life, many people may frequently experience numbness or cold hands and feet. In fact, this situation is not only related to inadequate insulation measures, but also to a lack of vitamin B12 in the body.
Generally speaking, the phenomenon of vitamin B12 deficiency is common among middle-aged and elderly people as well as children.
From a clinical perspective, if the human body lacks vitamin B12 for a long time, it can pose a certain degree of health risk. Below is a detailed introduction to the symptoms of vitamin B12 deficiency in the human body.
1. Symptoms of cardiovascular disease
For the human body, if vitamin B12 is lacking for a long time, it may trigger high homocysteine problems. Once this problem occurs, it is easy to trigger symptoms such as palpitations, chest tightness, and shortness of breath. If the situation is severe, it can even lead to a series of cardiovascular and cerebrovascular diseases, which seriously endanger our physical health.
2. Whitening of complexion
Vitamin B12 has the effect of promoting red blood cell production. If the human body lacks this vitamin, the number of red blood cells in the body will correspondingly decrease. In this situation, it may lead to insufficient energy and oxygen supply in the human body, and we may experience symptoms such as pale complexion, physical fatigue, and abnormal chills.
3. Dizziness and Headache
For friends with severe vitamin B12 deficiency in their bodies, they may also experience symptoms of pernicious anemia, which can easily harm our brain nerves.
Generally speaking, if the neural tissue of the human brain is damaged, it may be a problem of emotional instability. If the damage is severe, meetings can cause frequent dizziness and headaches.
4. numbness in hands and feet
Our body contains a substance called myelin, which is crucial for maintaining the normal operation of the human nervous system. Generally speaking, it can play a protective role in the human nervous system. In the synthesis process of this substance, the participation of vitamin B12 is often required.
Therefore, if the human body lacks vitamin B12, it will affect the normal synthesis of myelin, and over time, it will also affect the normal operation of the nervous system, leading to numbness in hands and feet.
For middle-aged and elderly friends who need to take medication for a long time, special attention should be paid, as certain chronic disease drugs may affect the body's absorption of vitamin B12, which may lead to a lack of vitamin B12 in the body over time.
This type of friend must pay attention to adjusting their dietary structure in daily life and try to ensure balanced nutrition, so as to enable the body to absorb enough vitamin B12.
