Overview
Effective measures for the secondary prevention of functional hypothalamic amenorrhea include oral contraceptive pills (OCPs), androgen therapy, recombinant insulin like growth factor 1 (IGF-1), recombinant leptin, bisphosphonates, and increasing calorie intake.
Secondary Prevention
- Effective measures for the secondary prevention of functional hypothalamic amenorrhea include:
Oral contraceptive pills (OCPs)
- Different studies have shown that OCP therapy can slow down the bone loss process in patients with exercise- and anorexia-associated amenorrhea. The detailed results are as following table:
Androgen therapy
- It is assumed that 50, 100, or 200 mg of micronized DHEA daily can increase bone mineral density (BMD), and prevent the osteoporotic fracture. But there is not any established long term study on the this effect.[1]
Recombinant insulin like growth factor 1 (IGF-1)
- It is approved that using recombinant insulin like growth factor 1 (IGF-1) (30 μg/kg−1 twice per day) along with OCP (0.035 mg ethinyl estradiol and 0.4 mg norethindrone) secondarily prevents the fracture in hypothalamic amenorrhea, due to anorexia nervosa, with increasing bone mineral density (BMD).[2]
Recombinant leptin
- It seems that administering recombinant Leptin (0.08 mg/kg) subcutaneous daily for 2–3 months would result in increasing bone formation markers; though, decreasing fracture risk through secondary prevention.[3]
Bisphosphonates
- In adolescent women with anorexia-induced amenorrhea, alendronate (10 mg) with calcium (1200 mg) and vitamin D (400 IU) for a year show significant improvement in bone loss. Therefore, they can be used as secondary prevention.[4]
- The major uses of bisphosphonates as secondary prevention for functional amenorrhea are as following table.
Increasing calorie intake
- Raising the efficient calories in daily meal and also weight gain in women with anorexia- or exercise-induced amenorrhea can increase bone mineral density (BMD) and also decrease the long term complications (osteoporosis and fracture).[5][6][7]
