TLDR Zinc and biotin supplements are needed after certain surgeries to prevent hair loss and other issues.
The document reported a case of zinc and biotin deficiencies in a 16-year-old female following a pancreaticoduodenectomy, which led to marked alopecia, total body hair loss, dry skin, and vision loss. These deficiencies were attributed to the resection of the duodenum and proximal jejunum, which are critical for the absorption of these micronutrients. The study emphasized the importance of early diagnosis and adequate supplementation to prevent irreversible damage.
