Vitamin B12 deficiency

A vitamin B12 deficiency is something that can trigger an episode of angioedema. This condition is where the patient's blood has a low level of vitamin B12.

Symptoms

Numerous medical symptoms can result when a patient has this deficiency. One thing that can occur is a loss of appetite. The patient may experience a sense of fatigue. Pain can affect the face, generally impacting one side of it at a time. Eye twitching is also among the possible symptoms. Numbness and tingling (sometimes referred to as paresthesia) can affect the body, especially the patient's limbs: arms and legs, including hands and feet.

A person with a vitamin B12 deficiency might also go through shortness of breath. Poor memory is another symptom that can result. Migraines can occur. A migraine is a particular disorder which involves headaches that tend to affect one side of the head. Migraines can also bring on symptoms of their own, such as nausea and vomiting, and more. They are also well known for their auras, which occur in around 20 to 30 percent of people who get them.

This is not a comprehensive list of things that may show up in this condition. Also, the simple fact that a person has symptoms from this collection does not mean that he has a vitamin B12 deficiency. Other medical reasons can lead to them. Talk with a doctor for diagnosis.


Causes

There are various reasons why a person might develop a vitamin B12 deficiency. One possibility is that the person merely does not receive enough of this vitamin in his diet. This occurs most commonly when someone does not eat animal products. Malabsorption in general can lead to a poor absorption of vitamin B12 in particular. Celiac disease also has the potential to lead to a poor absorption of of this. Certain genetic causes can lead to this deficiency, as well. Other causes can also be behind the situation.

Diagnosis

Although vitamin B12 levels in the blood can be measured, they may not always show as low even if the person does have a deficiency. Two things that can be measured and are thought to be more reliable in looking for a vitamin B12 deficiency are homocysteine and methylmalonic acid.

Treatment

Directly related to the level of this vitamin in the blood, it can be supplemented. However, underlying medical causes may need particular treatments of their own.
