2. Vitamin B6 Deficiency (or Excess)
Vitamin B6 helps control neurotransmitters, the chemicals that spread signals between nerves. Both low levels and excessive amounts can affect nerve function.
Symptoms of deficiency: tingling in the hands and feet, irritability, confusion, and anemia.
Risk factors: poor diet, alcoholism, or certain medications like isoniazid.
Prevention: eat bananas, poultry, fortified cereals, and potatoes. Always avoid high-dose supplements unless prescribed.
3. Vitamin B1 (Thiamine) Deficiency
Thiamine is crucial for transfering food into energy and supporting nerve health. Deficiency can destr0y peripheral nerves and cause numbness or weakness.
Causes of deficiency: chronic alcohol use, malnutrition, or prolonged diuretic use.
Associated conditions: beriberi and Wernicke-Korsakoff syndrome.
Food sources: whole grains, nuts, seeds, pork, and legumes.
4. Vitamin E Deficiency
Vitamin E is a mighty antioxidant that protects nerve membranes from damage. Severe deficiency, though rare, can lead to peripheral neuropathy.
Symptoms: loss of coordination, muscle weakness, and numbness.
Causes: genetic disorders affecting fat absorption or chronic conditions like cystic fibrosis.
Prevention: include nuts, seeds, spinach, and vegetable oils in the diet.
5. Niacin (Vitamin B3) Deficiency
A lack of niacin can cause pellagra, which is defined by dermatitis, diarrhea, dementia, and nerve-related issues including tingling and numbness.
Risk factors: alcohol dependence, poor diet, or certain gastrointestinal conditions.
Food sources: poultry, fish, peanuts, and fortified grains.
When to Worry
Occasional tingling that enhances after changing posture is usually harmless. But if numbness is persistent, spreading, or linked with weakness, dizziness, or confusion, it should not be neglected. Vitamin deficiencies can often be corrected with dietary changes or supplements, but long-term nerve damage may occur if left untreated.
