The Monitor Newspaper: Harvard Medical School explains that vitamin B12 deficiency can be slow to develop.
This may cause symptoms to develop gradually and increase in severity over time. However, the onset can be relatively quick for some. According to Russia Today.
According to health experts, one of the main signs to be aware of is a “strange” sensation in your hands that is a feeling of numbness or tingling in this area, which raises alarm bells.
Other body areas that can also be affected by this “strange” sensation include the legs and feet.
The NHS explains that this symptom occurs when blood flow to the nerves is cut off. This usually happens when you sit or sleep on one part of your body. It can be relieved by losing weight on the affected part of the body.
And while tingling or numbness can indicate a vitamin B12 deficiency, this is not the only symptom that indicates the condition.
Harvard Medical School explains that the diversity of signs can be confusing. However, knowing what to look for can help.
