Amenorrhea – Absence of Menstrual Periods, Animation

August 30, 2019

Amenorrhea is the absence of menstrual
periods in a woman of reproductive age absence of menses is normal in pregnant
breastfeeding and menopausal women but pathological otherwise amenorrhea is not
a disease on its own but rather a symptom of a variety of underlying
conditions primary amenorrhea is when a woman has never had her periods while
secondary amenorrhea is when a woman has stopped having them menstruation is part
of the menstrual cycle the monthly events that occur within a woman’s body
in preparation for the possibility of pregnancy each month an egg is released
from an ovary in a process called ovulation at the same time the lining of
the uterus thickens ready for pregnancy if fertilization does not take place the
lining of the uterus is shed in menstrual bleeding and the cycle starts
over the menstrual cycle is under control of multiple hormones secreted by
the hypothalamus pituitary gland and ovaries basically the hypothalamus
produces gonadotropin-releasing hormone GnRH the anterior pituitary secretes
follicle stimulating hormone FSH and luteinizing hormone LH while the ovaries
produce estrogen and progesterone these hormones are involved in a regulatory
network that results in monthly cyclic changes responsible for follicular
maturation and ovulation amenorrhea can be caused by anatomical
or endocrine problems anatomical causes refer to abnormalities in the female
reproductive system and include absence or underdeveloped female organs in some
genetic disorders such as MRKH syndrome congenital defects that obstruct blood
outflow and destruction of the uterine cavity by previous infections or
surgeries endocrine problems refer to structural or functional defects of the
hypothalamus pituitary gland and ovaries a common cause in this category is the
impaired function of the hypothalamus which occurs when the hypothalamic
pituitary ovarian axis is suppressed due to an energy deficit this can result
from weight loss eating disorders excessive exercise malabsorption
syndromes or emotional stress the common feature is a reduced production of GnRH
by the hypothalamus which results in corresponding low levels of FSH and LH
and subsequent impairment of follicular maturation and absence of ovulation
other endocrine causes include Kallmann’s syndrome a genetic disorder associated
with congenital defects of the hypothalamus causing GnRH deficiency
Sheahan syndrome a condition in which excessive blood loss during childbirth
or chronic hypotension during pregnancy impairs pituitary functions tumors
infections trauma or autoimmune destruction of the pituitary gland
polycystic ovary syndrome an endocrine disorder in which FSH deficiency
disrupts follicle maturation loss of normal ovarian function in conditions
such as Turner syndrome thyroid disorders
treatment is by addressing the underlying cause and can range from
nutrition plans hormonal therapy to surgical interventions you

  1. Isn't it normal to stop periods on certain contraception also? I have an implanon implant. I have periods when not on it but no periods when on it.

  4. I’m 19 and can’t even remember when I last had my menstrual cycle , sometime in 2016 to the start of 2017 I bled for almost a year then it just stopped since then I’ve had no period ?

  5. I had eating disorders in the past and it really messed up my period cycle I lost my period for about 4 months and it came back literally 1 day and it went away that exact day I'm not sure if that was even my period. Then I was clean without it for about 3 more months and it came back just today and I hope it stays for more than a day I'm starting to get worried that I'm probably got myself infertile

  6. Hi, my last period are in early 2016 and after that it never come again. I never go to check up or take any drugs. So what can i do now? Im 26th now and not married yet. Please give some advice or anything😔thanks in advance

  7. 7 month now no periods…. After using aherbal Chinese family planning pill.. But am having discomfort with my stomach., can it be amenoreah or fellopian tube blockage? Somebody help. Feeling worried

  8. I haven’t had my period in about a year tbh I don’t really even remember. I’ve always had my period like every few months or so never normal. I’ve also have never gone to a gynecologist before I have just kept putting it off and not really putting it first. I just turned 25 and am sexually active and I do have a thyroid condition so my hormonal imbalance is way off I’m always hot 🥵 and get hot flashes. Idk of that has anything to do with why I’m not getting my periods. I do get some spotting every now and then but just a little and I don’t have any pain or anything. I’m just a bit scared now since I haven’t had it in a long time!

  9. I wish I had amenorrhea, or menapouse. Women can't afford to ovulate when they are unemployed, lol, just being honost.

  10. I haven't had my period for 4 months since I stop the shot. I also am lactating but I'm not pregnant. I'm going to the doctor but I wish someone would tell me if this stuff was normal.

  11. I haven’t changed anything in my diet and i go on long walks every day or so. My period has been balanced my whole life, but in the beginning of this year my period would come and go when it felt like it and the ’blood’ was slimy and almost black. Now I haven’t had it for 4 months! I live a life of celibacy, so I can’t be pregnant. Can anybody help me?
