All About Thiamine (B1) and Thiamine Deficiency

Tingling Sensation in Arms and Legs
The peripheral nerves that reach your arms and legs rely heavily on the action of thiamine. In cases of deficiency, peripheral nerve damage and paresthesia can occur. In fact, patients have experienced paresthesia in the beginning phases of thiamine deficiency.Who is at risk of B1 deficiency? People with poor diet, cancer, “morning sickness” during pregnancy, bariatric surgery, and hemodialysis are at risk of thiamin deficiency. People who regularly drink alcohol to excess may have a deficiency, as they may not absorb thiamin from their food.
