What symptom is NOT associated with a deficiency of Thiamin?

A deficiency of Thiamin, also known as vitamin B1, is typically associated with symptoms such as fatigue, neural damage, and dermatitis, specifically in the context of conditions like beriberi and Wernicke-Korsakoff syndrome.

Fatigue occurs because Thiamin plays a crucial role in carbohydrate metabolism, and its deficiency can lead to a reduced production of energy. Neural damage can manifest as neurological symptoms, as Thiamin is vital for normal neural function. Dermatitis may also occur due to the broader impact of B vitamin deficiencies on skin health.

On the other hand, diarrhea is not a classic symptom of Thiamin deficiency. While some vitamin deficiencies can affect gut health and lead to digestive issues, Thiamin's primary deficiency-related symptoms do not commonly include diarrhea. This distinct lack of association identifies diarrhea as the answer that is not typically linked to a Thiamin deficiency.
