This essential vitamin plays a vital role in creating healthy red blood cells deficiency of vitamin b12 can cause a shortage of healthy RBCs, also called megaloblastic anemia which contains a link with jaundice. This anemia can also deteriorate the RBCs, which our body breaks further rapidly. Once the liver breaks RBCs, it discharges bilirubin. This brownish ingredient provides the skin with a yellowish nature, a feature of jaundice.

5. Breathlessness Is a Sign Of Vitamin B12 Deficiency

These problems contain difficulty in thinking or cognitive and memory damage. one research even associated low vitamin b12 concentrations with an augmented danger of Alzheimer’s, vascular dementia, and Parkinson’s syndrome. The decreased quantity of oxygen flow reaching the brain can be at fault for the thinking and cognitive problems.

13. Scratchy Hands or Feet

Vitamin b12 deficiency can create pins and needles on the hands and feet. This indication occurs as the vitamin plays a vital role in the human nervous system, and its deficiency can cause individuals to grow nerve conduction issues or nerve injury. In addition, this vitamin in the nervous system helps generate a substance named myelin.

Myelin is a defensive coating that protects the nerves and aids them in conveying sensations. Vitamin b12 is a vital sponsor of the metabolic passageway that generates myelin. Myelin covers our nerves as a form of defense and lining. Because of the shortage of vitamin b-12, myelin is created differently, and our nervous system is incapable of functioning appropriately.

Individuals who lack vitamin b-12 may not create enough myelin to cover their nerves. As a result, nerves can become injured. These problems are more common in the nerves of the hands and feet, known as peripheral nerves. Thus damage to the peripheral nerve may cause tingling in these body portions.

This is why your symptoms must be considered while making a diagnosis.

The current widely used blood test only measures the total amount of vitamin B12 in your blood, which is a significant disadvantage of testing vitamin B12 levels.

This implies that it distinguishes between vitamin B12 forms that are “active” and may be utilized by your body and those that are “inactive.”

A blood test may suggest that you have appropriate B12 levels even though your body cannot utilize much of it if a large quantity of vitamin B12 in your blood is inactive.
