Vitamin B12 Vaccinations in London
Vitamin B12 or folate deficiency anaemia occurs when a lack of vitamin B12 or folate causes the body to produce abnormally large red blood cells that cannot function properly.
Vitamin B12 is needed for physical growth and development also needed for forming red blood cells in the bones. It is needed for the absorption of certain vitamins and nutrients from food we eat such as folic acid and carbohydrates which are needed to keep our nerve system healthy.
Without a sufficient amount of daily vitamins over time this can lead to deficiency, this takes months or even years to develop. This causes abnormally large cells which reduces the ability of those cells to carry oxygen from enlarged cells in the bone marrow which in turn causes symptoms of anaemia.
What causes the anaemia?
The following things can cause anaemia:
- Pernicious anaemia.
- Conditions that affect the stomach – Surgery to remove all or part of the stomach (gastrectomy).
- Conditions that affect the intestines e.g crohns disease, Chronic gastritis (an autoimmune condition where the body attacks its own tissues).
- Lack of vitamins in your diet (Strict vegetarianism).
- Medicines (a doctor would monitor this with regular blood test to inform patient of B12 levels).
- Prophylaxis of macrocytic anaemia associated with vitamin B12.
The below is recommended for diet related B12 deficiency;
1. Consumption of good sources of vitamin B12 include:
b. Salmon and cod,
c. Milk and other dairy products,
e. For vegetarians or vegans, they have these such as yeast extract (marmite included), some fortified breakfast cereal and soy products.
2. Non-diet-related: –
Injection of hydroxocobalamin every 2-3 months for the rest of your life (per NHS recommendations).
There are two types of B12 injection, at London Vaccination Clinic we use Hydroxocobalamin as this has been shown to be more effective.
Hydroxocabalamin starts to work straight away. However, it may take a few days or weeks before your symptoms start to improve and you feel better.
Most adults and children can have hydroxocobalamin injection including pregnant women.
