Zinc Deficiency Presenting With Diverse Symptoms in a Young Patient: A Case Report

Despite its prevalence, zinc deficiency often goes undiagnosed due to nonspecific symptoms. This study examined the case of an 18-year-old woman who presented with urinary tract infection, anemia, and insulin dysfunction and was ultimately diagnosed with zinc deficiency. Oral zinc supplementation significantly improved the patient's condition. Zinc is essential for the activity of numerous enzymes and affects immune function, protein structure, and endocrine regulation, but the cause is often unknown because symptoms and data abnormalities are nonspecific. The patient's diet was high in foods that inhibited zinc absorption, likely exacerbating the deficiency. This case illustrates the importance of considering zinc deficiency in patients with diverse and unexplained symptoms. Prompt recognition and treatment with zinc supplementation can lead to rapid and complete recovery. We hope that this case will contribute to the future diagnosis of zinc deficiency for clinicians.
