Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2015, Vol 4, Issue 9
Abstract
[b]AIM OF THE STUDY[/b]: To study the effect of hypothyroidism, on the menstrual cycle of women in the reproductive age group. [b]MATERIAL & METHODS:[/b] A total number of 50 cases of hypothyroidism patients recruited over a period of one year from the department of Nuclear Medicine K.G.H Visakhapatnam. All these subjects were evaluated clinically and the data recorded as per the proforma. [b]RESULTS[/b]: In my study out of 50 hypothyroid women, 22% had normal menstrual cycle & 40% showed menorrhagia as major menstrual dysfunction. 18% had oligomenorrhea followed by 14% with polymenorrhea & 6% with amenorrhea. 14% of hypothyroid women had normal T3 & T4 levels. Out of 50 cases 6% had goiter and 20% showed no significant symptoms of hypothyroidism. Frequency of menstrual disturbances in hypothyroidism is approximately 3 times greater than in the normal population and main menstrual irregularity in these patients was oligomenorrhea which is also inconsistent with what is believed. Thyroid antibodies have no role in the development of menstrual abnormalities, suggesting that etiology has no role. Sub clinical hypothyroidism may be of greater clinical importance in infertile woman with menstrual disorders especially when the luteal phase is inadequate than is usually thought. [b]DISCUSSION[/b]: In our study, out of 50 hypothyroid women, 22% had normal menstrual cycles and 40% showed menorrhagia as major menstrual dysfunction.18% had oligomenorrhea, followed by 14% with polymenorrhea and 6% with amenorrhea. Women in the age group of 25-34 years showed menstrual dysfunction in 40% of the cases. 38% of the study group belongs to the age group of 35-44 years and 20% in 15-24 years, 2% in the age group of 45 years & above. 14% of the hypothyroid women had normal T3 & T4 levels. Out of 50 cases 6% had goiter and 20% showed no significant symptoms of hypothyroidism. [b]CONCLUSIONS:[/b] 1. Hypothyroidism affects the reproductive system more frequently in women. 2. Thyroid diseases in general & particularly hypothyroidism in premenopausal women are often associated with menstrual abnormalities. 3. In women of fertile age hypothyroidism may result in menstrual dysfunction.
