Alopecia in Preexisting Autoimmune Thyroid Disease in Family Medicine Practice: Can Hyperprolactinemia Induce Hair Loss? A Case Report

The document is a case report about a 27-year-old female with autoimmune thyroid disease (Hashimoto's thyroiditis) who experienced frontal alopecia and was also diagnosed with hyperprolactinemia. Despite treatment with topical minoxidil 5% foam for 3 months, her hair loss did not improve. The authors discuss the difficulty in treating hair loss when it is potentially caused by multiple factors, including endocrine disorders. They note that while hyperprolactinemia is associated with autoimmune diseases, there is no conclusive evidence that it directly causes hair loss. However, they propose that it might trigger the onset of autoimmune thyroid disorders. The report calls for a deeper understanding of hair loss mechanisms, including thorough hormone analysis, and suggests that prolactin levels should be checked in patients with hair loss to rule out endocrine disorders or malignancy. The case is unique due to the limited research on the link between hair loss and hyperprolactinemia in patients with autoimmune diseases.
