Vitamin B12 deficiency is a common condition that can occur when the body doesn’t get enough vitamin B12. This essential nutrient plays a vital role in the body, helping to produce red blood cells, DNA, and the protective sheath that covers nerve fibers. A deficiency of vitamin B12 can lead to a range of health problems, including anemia, nerve damage, and problems with brain function.
Symptoms of vitamin B12 deficiency can be subtle at first and may take years to develop. The most common symptoms include:
- Fatigue and weakness
- Lack of energy
- Shortness of breath
- Pale skin
- A smooth tongue
- Mouth sores or cracks in the corners of the mouth
- Changes in appetite, weight loss
- Constipation or diarrhea
- Nerve problems, such as numbness and tingling in the hands and feet
- Difficulty walking
- Memory loss, confusion, and difficulty thinking and making decisions
If left untreated, vitamin B12 deficiency can lead to more serious health problems, including anemia, nerve damage, and problems with brain function.
The treatment for vitamin B12 deficiency depends on the underlying cause of the deficiency. In many cases, treatment involves taking vitamin B12 supplements or receiving vitamin B12 injections. If the deficiency is caused by a medical condition, such as pernicious anemia or a gastrointestinal disorder, treatment may also involve addressing the underlying condition.
Vitamin B12 supplements are available in the form of tablets, capsules, and lozenges. They can be taken orally or dissolved under the tongue. Vitamin B12 injections are usually given by a healthcare provider and are administered intramuscularly (into a muscle) or subcutaneously (under the skin).
If the deficiency is caused by a medical condition, such as pernicious anemia, treatment may involve taking vitamin B12 injections or receiving vitamin B12 through a nasal spray or gel. In severe cases of vitamin B12 deficiency, a person may need to receive vitamin B12 through an intravenous (IV) injection.
It’s important to follow your healthcare provider’s recommendations for treating vitamin B12 deficiency. If you’re taking vitamin B12 supplements, it’s important to take them regularly as directed. If you’re receiving vitamin B12 injections, it’s important to receive them on schedule.
Vitamin B12 deficiency can be prevented by eating a healthy, balanced diet that includes foods rich in vitamin B12, such as meat, poultry, fish, eggs, and dairy products. Vegetarians and vegans may be at risk of vitamin B12 deficiency and may need to take supplements or receive vitamin B12 injections.
People who have had gastrointestinal surgery or have certain gastrointestinal disorders, such as Crohn’s disease or celiac disease, may also be at risk of vitamin B12 deficiency and may need to take supplements or receive vitamin B12 injections.
It’s important to talk to your healthcare provider if you think you may be at risk of vitamin B12 deficiency or if you’re experiencing any of the symptoms listed above. Early diagnosis and treatment can help prevent serious health problems and ensure that your body gets the vitamin B12 it needs to function properly.
