What is Vitamin B12?
Vitamin B12 is an essential vitamin that plays a key role in red blood cell formation and nervous system function. A lack of B12 can lead to anemia and neurological symptoms. It is primarily found in animal foods such as meat, fish, eggs and dairy products.
Why is B12 important?
B12 contributes to DNA synthesis, red blood cell production and nerve tissue maintenance. Deficiency can therefore affect both your circulation and your nervous system.
Symptoms of Vitamin B12 deficiency
Symptoms can develop gradually and are often overlooked. The most common symptoms are:
- Fatigue and weakness
- Difficulty concentrating
- Sensory disturbances in hands and feet
- Memory problems
- Pale skin
If you experience any of these symptoms, you should have your B12 levels measured.
Causes of B12 deficiency
There are several reasons why you may develop a B12 deficiency:
- Reduced absorption in the intestine (e.g. in celiac disease or Crohn's disease)
- Lack of intrinsic factor production (e.g. in pernicious anemia)
- Veganism or vegetarianism without adequate supplementation
- Long-term use of antacids
Diagnostics of B12 deficiency
A simple blood test can reveal B12 deficiency. At Doctors Denmark, we offer fast blood tests with results within a few days. If you have symptoms, early diagnosis can be crucial to avoid permanent damage.
Treatment of B12 deficiency
Treatment depends on the cause:
- Dietary supplements in the form of tablets or injections
- Changing diets to include more B12-containing foods
- Regular checks to make sure the treatment is working
Prevention of B12 deficiency
If you are vegetarian or vegan, you may need to take a daily B12 supplement. Older people and those with chronic intestinal diseases should also consider regular monitoring of B12 levels.
When should you contact your doctor?
If you experience persistent fatigue, sensory disturbances or difficulty concentrating, you should contact your doctor. Early detection of B12 deficiency can prevent serious complications such as nerve and brain damage.
