What should be alarming
Vitamin B12 is needed for the production of red blood cells, the normal functioning of the brain and the nervous system. Lack of substance can provoke a large number of complications of varying severity. For the timely detection of a dangerous condition, it is necessary to be able to recognize its symptoms.
According to the UK’s National Health Service (NHS), one of the most common signals of a deficiency in this compound is hearing problems, as nerve cells are damaged when the vitamin is constantly low. This can manifest itself in difficulty walking, muscle weakness, and memory loss. At the same time, as noted by experts, such damage can also occur in the ears.
Vitamin B12 deficiency has been found to have a negative effect on the production of myelin (the insulating coating that surrounds the nerves). As a result of its lack, the function of the ear nerves is impaired, which leads to tinnitus (incomprehensible buzzing or ringing).
In some cases, the sounds can be similar to hiss, buzzing, throbbing, and even whistling. People even reported hearing music that didn’t exist in reality.
“Lack of vitamin B12 can cause neurological problems. Since most cases of vitamin B12 or folate deficiency can be easily and effectively treated, irreversible complications are rare,” the experts shared, adding that their risk increases with chronic deficiency.
The NHS has advised that 1.5 micrograms of vitamin B12 be included in the daily diet. Additional intake is indicated for vegetarians and the elderly.
