VITAMIN B12 DEFICIENCY ANEMIA SYMPTOMS
Vitamin B12 deficiency anemia is type of megaloblastic anemia that develops when the body doesn’t absorb enough of this nutrient. Necessary for the creation of red blood cells, B12 is found in meat and vegetables.
Large amounts of B12 are stored in the body, so this condition may not become apparent until as much as four years after B12 absorption stops or slows down. The resulting drop in red blood cell production can cause:
- loss of muscle control
- loss of sensation in the legs, hands, and feet
- soreness or burning of the tongue
- weight loss
- yellow-blue color blindness
The most common form of B12 deficiency is pernicious anemia. Since most people who eat meat or eggs get enough B12 in their diets, a deficiency of this vitamin usually means that the body is not absorbing it properly.
Symptoms of vitamin B12 deficiency anemia
If your vitamin B12 deficiency is mild, you may not have symptoms or you may not notice them. Some people may think they are just the result of growing older. As the anemia gets worse, you may:
- Feel weak, tired, and lightheaded.
- Have pale skin.
- Have a sore, red tongue or bleeding gums.
- Feel sick to your stomach and lose weight
- Have diarrhea or constipation.
If the level of vitamin B12 stays low for a long time, it can damage your nerve cells. If this happens then develops following symptoms:
- Numbness or tingling in your fingers and toes.
- A poor sense of balance.
- Depression.
- Dementia, a loss of mental abilities.
A life-long regimen of B12 shots is necessary to control symptoms of pernicious anemia. For many people, pills work just as well as shots. The patient may be advised to limit physical activity until treatment restores strength and balance.
