Background: Thyroid disorders are more common in women than in men and in older adults compared with younger age groups.The present study was conducted to assess thyroid dysfunction in patients with abnormal uterine bleeding. Materials & Methods: 90 patients with abnormal uterine bleeding were enrolled.Assessment of serum triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH) level was done. Results: Age group 18-27 years had 25, 28-37 years had 30 and 38-47 years had 35 patients. The difference was non- significant (P> 0.05). The level of tri- iodothyronine was normal in 80, increased in 6 and decreased in 4, level of thyroxine was normal in 82, increased in 5 and decreased in 3 and level of TSH was normal in 76, increased in 8 and decreased in 6 patients. The difference was significant (P< 0.05). Out of 90 patients, 76 were euthyroid, 8 had hypothyroidism and 6 had hyperthyroidism. Under hypothyroidism, 3 had menorrhagia, 2 had oligomenorrhoea, 1 had menometorrhagia, 1 had polymenorrhoea and 1 had hypomenorrhoea. Under hyperthyroidism, 2 had menorrhagia, 2 had oligomenorrhoea, 1 had menometorrhagia and 1 had polymenorrhoea. The difference was significant (P< 0.05). Conclusion: Abnormal uterine bleeding patients had menorrhagia, oligomenorrhoea, menometorrhagia and polymenorrhoea complaints.
