Marijuana-Provoked Hypoprolactinemia and Impaired Bone Mineral Density: Case Report and Review of Literature

Introduction: The incidence of concurrent hypoprolactinemia and impaired bone mineral density (IBMD) induced by marijuana abuse has not been observed among the general population. To the very best of our knowledge, none of these two rare conditions have previously been documented among Nigerians, within the existing literature. Case Report: Herein, is a rare case of concurrent hypoprolactinemia and IBMD triggered by marijuana abuse, in a 21-year-old undergraduate Nigerian male, who is a regular/heavy marijuana smoker of thirteen months duration. He had presented in our medical facility with complaints of recurrent excruciating lower back pain of three weeks duration which intensified with walking and while undertaking weight-bearing activities. He attested to having and seeking medical attention for, excessive sweating, and insomnia symptoms before the onset of current presenting symptoms. Results of investigations showed positive urine test for marijuana, hypoprolactinemia, distortions of biomarkers of bone metabolism, and radiologic features consistent with IBMD, Having found no other discernible cause of the low back/hip pain and hyoprolactinemia, he was diagnosed clinically with hypoprolactinemia and IBMD secondary to marijuana abuse. This warranted hospital admission where he obtained standardized specialist medical care and was subsequently discharged in good clinical condition with an uneventful follow-up period. Conclusion: This case highlights the dangers of metabolic aberrations due to marijuana abuse and the need to always maintain a high index of suspicion when confronted with it to avoid unnecessary medical protocols.
