But your hands and feet may be trying to tell you something else. Here we’ve listed seven warning signs that may indicate vitamin B12 deficiency – and why you shouldn’t ignore them.

a common symptom of Vitamin B12 deficiency This is a tingling sensation in the hands and feet, often described as “pins and needles”. This is because B12 is important for maintaining the myelin sheath around and protecting the nerves. Without enough B12, nerve damage can occur, causing abnormal sensations. Over time, untreated deficiency can result in permanent nerve damage.

Numbness of hands or feet can also be a sign of vitamin B12 deficiency. This symptom occurs when nerve cells fail to transmit signals effectively due to B12 deficiency. This is a worrying sign that often accompanies the tingling and should not be ignored, especially if it persists or worsens.

Vitamin B12 deficiency can affect the motor nerves, causing the muscles in the hands and legs to become weak. This can make simple tasks like holding objects or walking difficult. Over time, untreated deficiency can impair mobility and balance.

Do your hands and feet feel unusually cold? This could be another warning sign. B12 is important for the production of healthy red blood cells that carry oxygen throughout the body. Its deficiency can lead to anemia, resulting in reduced blood flow and a feeling of coldness in extreme weather conditions.

Some people with vitamin B12 deficiency complain of a burning sensation in their hands or feet. This symptom is associated with nerve damage caused by insufficient B12 levels. The burning sensation may be mild in the beginning but if the problem is not taken care of, the burning sensation may become severe.

Severe deficiency of vitamin B12 can cause difficulty with balance and coordination. This symptom is especially pronounced in the feet and legs, making activities such as walking or climbing stairs challenging. If ignored, it can significantly impact overall mobility.

Pale or pale skin (jaundice) on the hands and feet is another symptom of vitamin B12 deficiency. This is caused by the lack of healthy red blood cells and the breakdown of hemoglobin, releasing bilirubin which gives the yellow color to the skin. Brittle nails or slow-healing wounds on the hands and feet may also indicate a deficiency.

What causes Vitamin B12 deficiency?

Several factors can cause vitamin B12 deficiency, including:

– Dietary deficiencies: People following vegetarian or vegan diets are at greater risk because B12 is primarily found in animal-based foods such as meat, eggs and dairy.

– Malabsorption: Conditions such as pernicious anemia, Crohn’s disease, or celiac disease can interfere with B12 absorption.

– Medication: Long-term use of medications such as proton pump inhibitors (PPIs) and metformin can interfere with B12 absorption.

– Aging: Older adults often have decreased levels of stomach acid, which is essential for B12 absorption.

Who is at risk?

According to studies and experts, the following are at risk:

– People above 50 years of age.

– Vegetarians and vegans.

– Those with gastrointestinal disorders.

– Those taking some medicines for a long time.

– Pregnant or lactating women with inadequate dietary intake.

How is Vitamin B12 Deficiency Diagnosed?

Diagnosis involves a combination of medical history, physical examination, and laboratory tests. A blood test can measure B12 levels and identify anemia. In some cases, additional testing, such as methylmalonic acid (MMA) or homocysteine ​​levels, may be needed for confirmation.

treatment and prevention

Treatment depends on the severity of the deficiency:

– Dietary changes: Including foods rich in B12 such as eggs, dairy, fish and fortified cereals can help prevent deficiency.

– Supplements: Oral B12 supplements or multivitamins are effective for mild deficiencies.

– Injections: In severe cases, intramuscular B12 injections may be necessary to quickly restore levels.

To prevent deficiency, at-risk individuals should get regular testing and consider B12 supplementation if necessary.
