Understanding Vitamin B12 Deficiency
Key Information
- Why We Need B12: Vitamin B12 is crucial for producing healthy red blood cells, which carry oxygen around your body.
- The Problem: When levels are low, your body produces abnormally large red blood cells that cannot function properly. This can lead to a specific type of anaemia.
- Common Symptoms: You may experience extreme tiredness, a lack of energy, "pins and needles," mouth ulcers, or difficulties with memory and concentration.
- Effective Treatment: This condition is very treatable. We have prescribed a course of high-dose tablets to boost your levels and resolve these symptoms.
What Happens Next?
Your treatment plan involves taking daily high-dose tablets to rebuild your body's B12 stores. It is important to stick to this schedule to make sure the treatment works. We will monitor your progress with follow-up blood tests to ensure your levels return to normal.
If you have specific questions about your diagnosis or need support with your treatment, we are here to help.
