Vitamin B12 deficiency is one of the most common nutritional problems seen worldwide. This condition can affect energy levels, nerve health, and overall well-being. This article helps you understand anaemia in individuals who often experience reduced stomach acid, which can affect ulcers, and the importance of Vitamin B12, its deficiency symptoms, causes, and treatment options for better health.
What is Vitamin B12?
Vitamin B12, also known as cobalamin, is an essential vitamin that supports:
- Red blood cell formation
- Nerve health and brain function
- DNA synthesis
- Energy metabolism
Since our body cannot produce Vitamin B12 naturally, it must be obtained from diet or supplements.
Causes of Vitamin B12 Deficiency
There are several reasons why someone may develop a deficiency, including:
- Dietary Deficiency – Common in vegetarians and vegans due to a lack of animal-based foods.
- Digestive Disorders – Conditions like Crohn’s disease, celiac disease, or pernicious anaemia reduce absorption.
- Medications – Long-term use of antacids, proton pump inhibitors, or metformin may interfere with absorption.
- Age-related Factors – Elderly individuals often experience reduced stomach acid, which can affect Vitamin B12 absorption.
Symptoms of Vitamin B12 Deficiency
Early detection is essential. Look out for these common Vitamin B12 deficiency symptoms:
- Constant tiredness and weakness
- Numbness or tingling in hands and feet
- Memory issues and mood changes
- Pale or yellowish skin
- Difficulty walking or poor balance
- Sore tongue or mouth ulcers affect anaemia in individuals.
If ignored, the condition can lead to permanent nerve damage.
How is Vitamin B12 Deficiency Diagnosed?
Your doctor may recommend a blood test to check Vitamin B12 levels. Additional tests, such as those for methylmalonic acid or homocysteine, may be used for confirmation.
Treatment for Vitamin B12 Deficiency
Dr. Anitha’s treatment approach depends on the severity of the deficiency:
- Dietary Modifications – Include eggs, milk, fish, chicken, and fortified cereals, such as those for methylmalonic acid or homocysteine.
- Supplements – Vitamin B12 tablets or capsules for mild cases.
- Injections – For severe deficiency or absorption-related issues.
- Regular Monitoring – Follow-up tests to ensure healthy levels.
How to Prevent Vitamin B12 Deficiency?
- Eat a balanced diet rich in Vitamin B12 sources.
- Vegetarians and vegans should take fortified foods or supplements.
- Go for regular health check-ups, especially if you are above 50 years old.
Expert Advice by Dr. Anitha
