Vitamin B1

Why Does a Vitamin B1 Deficiency Occur?

Vitamin B1 (thiamine) deficiency occurs due to inadequate dietary intake, malabsorption, or increased bodily requirements. Risk factors include alcoholism, which impairs thiamine absorption and storage, and diets high in refined carbohydrates but low in thiamine-rich foods like whole grains, legumes, and meat. 

Chronic illnesses such as diabetes, HIV/AIDS, and gastrointestinal disorders can also reduce thiamine absorption or increase its need. Additionally, conditions like hyperthyroidism, pregnancy, and lactation increase thiamine requirements, potentially leading to deficiency if dietary intake is not adjusted accordingly.

What to Do About Vitamin B1 Deficiency?

Vitamin B1 deficiency can be addressed by increasing intake of thiamine-rich foods, such as whole grains, legumes, nuts, seeds, pork, and fortified cereals. For those unable to get enough thiamine through diet alone, supplements may be necessary. 

Treatment for severe deficiency often involves thiamine injections. It is crucial to identify and manage any underlying conditions contributing to the deficiency to prevent recurrence and ensure overall health.
