NHS warns of serious health risks from vitamin B12 deficiency including tingling in feet

Vitamin B12 deficiency can cause serious health issues, including tingling in the feet and muscle weakness. This condition arises when the body cannot absorb enough B12 from foods like eggs and meat, leading to symptoms that may mimic other conditions. The NHS highlights that untreated B12 deficiency can result in complications such as peripheral neuropathy, which affects nerve function and can worsen foot pain. Symptoms include extreme tiredness, a sore tongue, and cognitive issues. Health experts recommend seeing a doctor if B12 deficiency is suspected. Early diagnosis and treatment are crucial, as some effects may become irreversible if left unaddressed.
