The three first signs of vitamin B12 deficiency are named

Vitamin B12 is necessary for the proper functioning of the body. As a rule, to get the optimal amount of this substance, it is enough to include several types of products in the diet. Most B12 is found in meat, fish and milk. When the level of the vitamin in the blood is too low, the body starts sending different signals. Most often, the first changes affect three parts of the body.

Tongue

One of the early symptoms of B12 deficiency is minor changes in the condition of the tongue. It usually begins to swell, change color and become painful. Sometimes it can seem like the taste buds are gone and itching appears, experts at Thyroid Patient Advocacy said. “Itching appears on the tip of the tongue or along one of the sides. There is an irresistible desire to scratch the tongue against the tooth. Some people experience tingling or pain, which is also a sign of B12 deficiency,” the doctors clarified.

Eyes

Unusual visual impairment is usually also caused by a lack of the vitamin. The condition is associated with damage to the optic nerve. As experts explained, due to the deficiency of the substance, the nerve impulse that goes from the eye to the brain can no longer be transmitted correctly, which inevitably leads to vision loss.

Nervous system

Vitamin B12 deficiency causes damage to the nervous system, due to which changes in gait and movements are observed. In this case, a person begins to experience problems with balance and coordination.
