Vitamin B12 is an essential element for the functioning of the nervous system, the formation of DNA, and the formation of red blood cells. Because the body cannot manufacture it itself, it must be obtained from food, such as fish, meat, eggs, and fortified foods.

However, factors such as medical conditions and certain medications may hinder its absorption, so the risk of deficiency increases. Here are six signs that may indicate that you are not getting enough of it, according to a report published by the “Health” website.

Fatigue is one of the most common symptoms of low B12. When the vitamin is deficient, the body is unable to produce healthy red blood cells that transport oxygen throughout the body. When your organs and muscles don't get enough oxygen, you may feel constantly tired and as if you never get enough sleep.

A B12 deficiency may lead to anemia, a condition in which the body lacks healthy red blood cells, which means a deficiency of hemoglobin, the oxygen-carrying component that gives blood its red color. As it decreases, the skin appears pale.

Another classic sign of anemia is the pallor of the conjunctiva, that is, the inside of the eyelids becomes white or pale pink, when they are usually bright red.

You may feel like you can't catch your breath, or gasp easily when climbing the stairs or walking to the car. Low hemoglobin means less oxygen reaching the tissues, so the body compensates for this by accelerating the heartbeat and increasing breathing, which causes a feeling of fatigue even with normal daily activity.

People with low B12 levels may experience frequent headaches, due to several factors, including the buildup of homocysteine, an amino acid that B12 helps convert to methionine.

With a vitamin deficiency, homocysteine ​​may accumulate in the blood and irritate the blood vessels, contributing to headaches. Low oxygen and changed levels of nitric oxide, a signaling molecule, may also play a role.

People with B12 deficiency often complain of weakness, partly because the muscles are less supplied with oxygen, making them appear tired or heavy. In more severe cases, the deficiency may cause nerve damage, as the vitamin is needed to maintain myelin, the protective covering of the nerves. Without it, this coating may disintegrate and disrupt nerve signals, leading to muscle weakness, numbness, and balance problems.

B12 deficiency may affect mental health, causing mood changes and possibly depression and anxiety. The vitamin is necessary for the production of neurotransmitters that regulate mood, such as serotonin and dopamine. It is also important for nerve health, and its deficiency may cause brain inflammation and nerve damage that triggers mood swings.

The risk of deficiency increases in certain groups, most notably the elderly, those who follow strict vegetarian diets, those who take certain medications, such as metformin and proton pump inhibitors, those who have undergone stomach surgery, and those with conditions that impede absorption, such as Crohn's disease.

If you suspect your B12 level is low, make an appointment with your doctor. He or she can order a blood test to measure the level and recommend treatment if a deficiency is found. Depending on your health history and the cause of the deficiency, treatment may include vitamin B12 supplements.
