There are several signs that could indicate a deficiency in vitamin B12, one of which is a tingling sensation in the feetand hands. Vitamin B12, found in foods such as eggs, beef, chicken and cheese, is reabsorbed into the body through the gut.
B vitamins play a crucial role in wound recovery as they aid in the production of red blood cells, essential for oxygen circulation in the body. They also contribute to eye health, a robust immune system, protein absorption, DNA synthesis and the formation of red blood cells.
According to Express, an expert has stated that a lack of this vitamin can impact wound healing in various ways. A key protein called intrinsic factor (IF), produced by stomach cells, binds to vitamin B12. Without IF, vitamin B12 is lost during digestion. If the body’s immune system attacks the stomach cells, IF won’t be produced in significant amounts.
In such cases, problems with the feet, such as tingling sensations, can occur. Vitamin B12 deficiency may cause “pins and needles” in the hands or feet. This symptom occurs because the vitamin plays a crucial role in the nervous system. Its absence can cause people to develop nerve conduction problems or permananent nerve damage.
In the nervous system, vitamin B12 helps produce a substance called myelin that shields the nerves and helps them transmit sensations. Without sufficient myelin, nerves are more prone to damage.
Problems are more common in the nerves in the hands and feet, which are called peripheral nerves. Peripheral nerve damage may lead to tingling in these parts of the body.
Therefore, if you experience such symptoms, it’s advisable to consult your GP. An expert from the University of Nottingham highlighted that a “lack of vitamin B can affect wound healing in a number of ways”, particularly in relation to the feet, as reported by DevonLive. Doctors may recommend or prescribe high-dose vitamin B12 supplements.
However, if symptoms worsen, weekly vitamin B12 injections might be necessary. It’s crucial to address a vitamin B12 deficiency as it can lead to serious neurological issues and blood diseases. Other symptoms of a lack of the vitamin include; Harvard Medical School warned: “Vitamin B12 deficiency can be slow to develop, causing symptoms to appear gradually and intensify over time.”
They also pointed out that a deficiency “might also occur following weight-loss surgery too.” Overuse of heartburn medication can lead to less acid production in the stomach, which is crucial for vitamin B12 absorption – potentially leading to a deficiency. Vitamin B12 supplements are available for purchase online, from pharmacies, or can be prescribed by a doctor.
