Beriberi

Beriberi is a disease caused by a deficiency of thiamine, also known as vitamin B1, an essential nutrient for the proper functioning of the nerves, the muscles, and the heart.

How it can show up: Depending on the form it takes, one may notice muscle weakness, tingling or numbness in the extremities, difficulty walking, swelling, and, in other cases, heart-related discomfort such as palpitations or fatigue.

When to seek evaluation: In the case of persistent symptoms in a context of a poorly varied diet or nutrient absorption problems, a review is advisable to clarify the cause.

Which specialist treats it? In the pediatric population, the pediatrician assesses the child's nutritional and developmental status, identifies possible deficiencies, and provides guidance on the path forward. Maintaining a balanced diet and discussing any concerns with a professional is always advisable.
