Understanding Vitamin B12 Deficiency & Injection Treatment
Key Information
- The Role of B12: Vitamin B12 is essential for creating healthy red blood cells that transport oxygen throughout your body.
- The Consequence of Deficiency: Without enough B12, your body produces abnormally large red blood cells that cannot function correctly, leading to a specific type of anaemia.
- Symptoms: Common symptoms include extreme tiredness, "pins and needles," mouth ulcers/sore tongue, and issues with memory or concentration.
- Treatment Plan: Because your levels are low, we will treat this with a course of B12 injections to boost your levels, followed by a maintenance injection every three months.
What Happens Next?
Your treatment will involve visiting the practice for your scheduled injections. It is vital that you attend these sessions to allow your body to rebuild its B12 stores effectively. We will continue to monitor your progress with follow-up blood tests.
If you have specific questions about your diagnosis or need support with your treatment, we are here to help.
