About this trial
Women with hypothyroidism often report persistent fatigue, weight gain, autonomic dysregulation, and stress despite stable levothyroxine therapy. This single-center, parallel-group RCT will test whether a structured, supervised 12-week walking program improves basal metabolic rate (BMR) and psychophysiological outcomes compared with usual activity. One hundred twenty women aged 35-55 with stable primary hypothyroidism will be randomized 1:1 to intervention or control.
