Abstract Thyrotoxic Periodic Paralysis (TPP) is a rare condition associated with hyperthyroidism, particularly in young males. This report presents the case of a 20-year-old male with TPP complicated by decreased bone mineral density (BMD). While TPP is primarily a neuromuscular disorder characterised by hypokalaemia-induced periodic paralysis, this case highlights the less-recognised impact of prolonged hyperthyroidism on bone metabolism, resulting in significant bone loss.
