Functional hypothalamic amenorrhea (FHA) is a form of amenorrhea and chronic anovulation [1] and is one of the most common types of secondary amenorrhea. [2] It is classified as hypogonadotropic hypogonadism. [3] It was previously known as "juvenile hypothalamosis syndrome," prior to the discovery that sexually mature females are equally ...
Secondary amenorrhea's most common and most easily diagnosable causes are pregnancy, thyroid disease, and hyperprolactinemia. [50] A pregnancy test is a common first step for diagnosis. [50] Similar to primary amenorrhea, evaluation of secondary amenorrhea also begins with a pregnancy test, prolactin, FSH, LH, and TSH levels. [13]
In the case of RED-S, the majority of secondary amenorrhea cases are attributed to functional hypothalamic amenorrhea (FHA), an adaptive mechanism to preserve energy for survival and vital processes rather than reproduction when energy balance is low. [17] [18] Primary amenorrhea is characterized by delayed menarche (the onset of menses during ...
In secondary amenorrhea, or the absence of menstruation for greater than 6 months, can be caused by the same reasons as primary amenorrhea, as well as polycystic ovary syndrome, pregnancy, chronic illness, and certain drugs like cocaine and opioids. [23]
Weight loss is normally the first option for overweight women with PCOS. Multiple studies have illustrated the marked improvement in endocrine profile, menstrual cycle, rate of ovulation, and likelihood of healthy pregnancy amongst women who have lost weight. [48]
A pregnancy where the mother is weak could pose a risk to the baby's and mother's health. On the other hand, excess weight can also create ovarian dysfunctions. Dr Barbieri of Harvard Medical School has indicated that cases of anovulation are quite frequent in women with a BMI (body mass index) over 27 kg/m2.
In the 0.075mg and 0.15mg doses, the mother monkeys ate less, lost weight, and didn’t gain as much weight as usual during pregnancy. Researchers also noted birth defects in the bones of the baby ...
The history of a pregnancy event followed by a D&C leading to secondary amenorrhea or hypomenorrhea is typical. Hysteroscopy is the gold standard for diagnosis. [18] Imaging by sonohysterography or hysterosalpingography will reveal the extent of the scar formation. Ultrasound is not a reliable method of diagnosing Asherman's Syndrome.
