Unveiling the Link Between Celiac Disease and Premature Graying of Hair: A Case Report and Discussion on the Potential Implications for Diagnosis and Management.

Celiac disease (CD) is a systemic autoimmune disorder triggered by gluten ingestion in genetically predisposed individuals and characterized by diverse clinical presentations. Despite its prevalence, CD often remains undiagnosed due to its heterogeneous symptoms and inadequate awareness. Here, we present a case of a 42-year-old male with gastritis who presented with epigastric discomfort and pancytopenia. Initial investigations revealed a hemoglobin level of 3.7 g/dL, a mean corpuscular volume (MCV) of 84 fL, a white blood cell count (WBC) of 2420 cells/μL, a neutrophil count (NEU) of 1400 cells/μL, and a platelet count (PLT) of 140,000 cells/μL. A diagnostic workup revealed evidence of CD, and after that, the diagnosis was confirmed by gastro-colonoscopy. The patient's subsequent adherence to a gluten-free diet resulted in significant clinical improvement. Notably, during follow-up appointments, a notable change in the patient's hair color was observed, prompting further inquiry. The patient reported experiencing premature graying of hair during his late thirties, which remained unchanged until the diagnosis of CD and the initiation of a gluten-free diet. This unique manifestation highlights the potential association between CD and premature graying of the hair, warranting further investigation. While the precise mechanism remains unclear, it is plausible that CD-induced malabsorption and nutritional deficiencies may contribute to such changes. Therefore, we advocate for increased awareness and international collaboration to enhance understanding of this phenomenon and its implications for CD management. This case underscores the importance of early diagnosis and management of CD, as well as the potential for dietary interventions to alleviate associated symptoms and complications.
