Fatigue, weakness, difficulty concentrating, tingling or numbness
due to nerve damage, and, in severe cases, heart-related issues are symptoms
associated with thiamine deficiency, measured through Vitamin B1 levels in
whole blood. Thiamine, a crucial nutrient for energy metabolism and nerve
function, becomes deficient due to factors like poor dietary intake or
malabsorption. These symptoms collectively characterize a condition known as
beriberi. Monitoring and addressing thiamine deficiency through dietary changes
or supplements are essential for preventing and managing the associated
symptoms and potential complications.
