10 Causes of Paresthesia
Reviewed: Dr. Gromatzky
Cause #5: Vitamin Deficiency or Malnutrition
Vitamin deficiency occurs when there is long-term deficiency of a vitamin. When it occurs due to inadequate nutrition, it is a primary deficiency. When it is due to another disorder such as malabsorption, it is a secondary deficiency.
Different vitamin deficiencies result in different conditions. For example, vitamin A deficiency causes keratomalacia, thiamine deficiency leads to beriberi or Wernicke-Korsakoff syndrome, and niacin deficiency causes pellagra. Paresthesia can occur in vitamin deficiency and malnutrition as the nerve cells are unable to receive proper nutrients and can no longer function normally.
