Vitamin B12 is a vital nutrient that plays a crucial role in maintaining the health of various body systems. It is mainly found in animal-based foods such as meat, fish, and dairy products. The recommended daily intake of B12 for adults is around 2.4mcg.

However, some people may have low B12 levels due to various reasons such as poor diet, malabsorption, or medical conditions that affect the digestive system. While the well-known symptoms of B12 deficiency include fatigue, weakness, and pale skin, there are some unusual symptoms as well that may be caused by low B12 levels.

In this article, we will explore 10 uncommon symptoms that may indicate a B12 deficiency.

Hair Changes

Low B12 levels can affect the health of your hair, leading to changes such as hair loss, thinning, and premature graying.

In severe cases, B12 deficiency can cause a condition called pernicious anemia, which damages the hair follicles and leads to permanent hair loss. If you notice any changes in your hair, it may be worth checking your B12 levels.

Balance Problems

B12 deficiency can also affect your balance and coordination due to damage to the nerves that control these functions. This can lead to unsteadiness, dizziness, and falls, especially in older adults.

If you experience balance problems, it is essential to consult your doctor and get your B12 levels checked.

Changes in Taste and Smell

Some people with B12 deficiency may experience changes in their sense of taste and smell. They may find that their favorite foods taste different or that they struggle to discern different flavors and spices.

This may be due to damage to the nerves that control these senses and can lead to a loss of appetite and weight loss.

Mental Health Issues

B12 is essential for healthy brain function, and low levels of this vitamin can lead to various mental health issues such as depression, anxiety, and dementia.

In some cases, B12 deficiency may mimic the symptoms of Alzheimer’s disease, with confusion, memory loss, and difficulty concentrating. It is important to recognize these signs and get your B12 levels checked if you experience any mental health issues.

Mouth Ulcers and Tongue Changes

B12 is essential for maintaining healthy skin, including the delicate tissues of the mouth and tongue. Low levels of this vitamin can lead to the development of mouth ulcers, glossitis (inflammation of the tongue), and a sore, smooth, and red tongue.

These symptoms can be painful and affect your ability to eat and speak, so it is crucial to seek medical attention if you experience them.

Vision Changes

B12 deficiency can also affect your eyesight, leading to vision changes such as blurry vision, double vision, and optic neuropathy.

This condition causes damage to the optic nerve that transmits visual information from the eyes to the brain, leading to irreversible vision loss if left untreated.

Heart Palpitations

If you experience heart palpitations, a feeling of skipped beats or racing heart, it may be due to a B12 deficiency.

This is because B12 is essential for the formation of healthy red blood cells that transport oxygen to the body’s organs, including the heart. Low levels of B12 can lead to anemia, which reduces the oxygen-carrying capacity of the blood and puts a strain on the heart.

Lightheadedness

Low B12 levels can also cause lightheadedness, a feeling of faintness or dizziness.

This is because B12 plays a crucial role in maintaining healthy blood pressure levels and regulating the activity of the autonomic nervous system that controls the heart rate and blood flow. If you experience lightheadedness, it may be due to a B12 deficiency.

Numbness and Tingling

B12 deficiency can cause nerve damage, leading to numbness and tingling sensations in the hands and feet. This condition is known as peripheral neuropathy and can affect your ability to feel heat, cold, or pain.

It can also cause muscle weakness and difficulty walking, so it is essential to seek medical attention if you experience these symptoms.

Fatigue and Weakness

While fatigue and weakness are common symptoms of B12 deficiency, severe or prolonged deficiency can lead to extreme tiredness, muscle weakness, and difficulty walking.

This may be due to anemia, nerve damage, or metabolic changes that affect energy production in the body. If you experience severe fatigue or weakness, it is important to get your B12 levels checked and seek medical attention if necessary.

Conclusion

B12 deficiency can cause a range of symptoms that affect various body systems, from the nervous and cardiovascular systems to the skin, hair, and senses.

It is important to recognize these symptoms and get your B12 levels checked if you experience them, especially if you are at risk of deficiency due to a vegetarian or vegan diet, digestive issues, or medical conditions that affect nutrient absorption. With timely diagnosis and treatment, B12 deficiency can be easily managed, and the symptoms can be reversed.
