Purpose: To identify endocrine abnormalities such as hyperandrogensim, thyroid disorders, and hyperprolactinemia in adolescents with menstrual disorders. Methods: This was a case-control study carried out in adolescent girls aged 10-19 years in the gynecology outpatient department of a tertiary care hospital. The participants' demographic details, medical, surgical, family, and personal history was obtained. Data of hormonal evaluation, namely serum T3, T4, TSH, serum prolactin and serum testosterone was also collected. Results: The most common menstrual abnormality was oligomenorrhea at 66% followed by menorrhagia at 10%. Primary amenorrhea was seen in 8% cases, metrorrhagia was seen in 4% and polymenorrhea in 4% of cases. Secondary amenorrhea and hypomenorrhea were both seen in 2% of cases. 10% adolescents with menstrual abnormalities had biochemical hyperandrogenism. Only 2% had hyperandrogenism in the control group. Thyroid dysfunction was more prevalent in the adolescents with menstrual disorders (14%) when compared to controls (4%). Among those with oligomenorrhea, only in one case was serum prolactin raised (3.0%). Conclusion: Immaturity of hypothalamic pituitary ovarian axis is considered to be the most common cause of menstrual irregularities in adolescent girls, but endocrine abnormalities may be responsible in some cases. Therefore it is paramount to examine the prevalence endocrine abnormalities among among adolescents with menstrual problems to promote their quality of life, lower her risks for future disease, and ill health.
