B12 Deficiency Symptoms, Causes, and Treatment: Understanding the Signs, Sources, and Solutions
Vitamin B12 is a vital nutrient, crucial for the creation and maintenance of your nerves and red blood cells, supporting the nervous system, and helping in creating DNA – the blueprint of all cells. However, an insufficient intake or poor absorption methods can result in severe health complications. Let's dive into the world of this essential vitamin, knowing the risks, symptoms, and treatments for vitamin B12 deficiency.
What's the Vitamin B12 Amount You Need?
The recommended daily allowance of vitamin B12 varies depending on age and pregnancy. Here's a quick chart to help you understand the right intake for each age group:
| Age Group | Recommended Daily Intake (micrograms) || --------------- | ------------------------------------ || Newborns | 0.4 || Infants | 0.5 || Toddlers | 0.9 || Children | 1.2 || Pre-teenagers | 1.8 || Teens & Adolescents | 2.4 || Adults | 2.4 || Pregnant Women | 2.6 || Breastfeeding Women | 2.8 |
Causes of B12 Deficiency
0.4
Several factors might lead to a vitamin B12 deficiency. Here are some common causes to be aware of:
- Pernicious anemia: An autoimmune disease that compromises the digestion of vitamin B12, causing a shortage that leads to severe health problems.
- Bowel problems: Certain stomach or small intestine issues may prevent efficient absorption of the vitamin, like Crohn's disease or surgery that reduces the size of the stomach or the length of the intestine.
- Diet: Individuals following a plant-based diet may have a higher risk of B12 deficiency, particularly during pregnancy as it may increase the risk of neurological damage to the fetus.
- Medications: Proton pump inhibitors (PPIs) and Histamine H2 receptor agonists (H2 blockers), medications prescribed for indigestion or gastroesophageal reflux disease (GERD), can decrease vitamin B12 absorption. Metformin, a diabetes medication, is also associated with vitamin B12 deficiency.
- Functional vitamin B12 deficiency: In some cases, individuals may have normal blood levels of vitamin B12 but lack the proteins needed to transport it effectively between cells.

Symptoms of Vitamin B12 Deficiency
If your body lacks sufficient vitamin B12, you may experience several symptoms:
0.9
- Fatigue and weakness
- Constipation
- Loss of appetite and weight loss
- Problems with balance
- Depression
- Problems with concentration
- A sore mouth or tongue
In infants, signs may include:
1.2
- Not growing or developing at the expected rate
- Problems with movement
- Megaloblastic anemia
Complications
1.8
Untreated vitamin B12 deficiency can have severe long-term consequences. High levels of homocysteine, linked to some health conditions like dementia and cardiovascular disease, may increase the risk.
- Dementia and cognitive decline: Low levels of vitamin B12 may affect brain function over time, potentially leading to reduced school performance in children, irritability, memory loss, depression, and dementia.
- Neurological damage: Studies have shown that people with B12 deficiency may suffer from nerve damage, damage to the spinal cord, and neurological issues affecting mental health.
- Cardiovascular disease: High levels of homocysteine have been found in people with coronary heart disease and stroke. However, there is currently no evidence that B12 supplementation prevents heart diseases.

Energy Levels and Supplementation
While some individuals may take vitamin B12 supplements to boost energy levels and athletic performance, supplements should only be used in cases where a deficiency already exists. Only use supplements recommended by a medical professional.
Diagnosis, Treatment, and Prevention
Your doctor will likely ask about symptoms, perform a physical examination, and test your blood to check for B12 levels and anemia, if necessary. Regular testing for people with chronic gastrointestinal issues can help ensure a deficiency doesn't develop.
To prevent B12 deficiency, maintain a well-balanced diet, including vitamin B12-rich foods like clams, beef liver, fish, nutritional yeast, dairy products, eggs, and fortified yeasts and other foods.
People with specific conditions, like pernicious anemia, Crohn's disease, or gastrointestinal issues, may require additional B12 supplementation or a specialized treatment plan. Consult with a medical professional to determine the best course of action.
In conclusion, vitamin B12 plays a crucial role in preventing anemia and maintaining neurological health, potentially helping prevent dementia and heart disease. A balanced diet and monitoring your B12 levels can often help prevent deficiency, especially important for vegetarians, older adults, and individuals with chronic gastrointestinal problems. Seek medical help if you experience symptoms of vitamin B12 deficiency and work closely with your doctor to ensure proper diagnosis and treatment.
