what is the cause for inregular menstration?
108314
There are all sorts of causes...but you should ask a qualified medical expert if you're having problems. I will say that there are some women who don't have them at all until they take certain medications. I don't know anything more specific, though. Do call your family physician or a good OB/GYN.

When a woman ceases to menstruate (in those cases not related to pregnancy or depo provera), that's actually her body giving a very strong signal that something is WRONG with her body.\n\nHere are some conditions during which a woman might cease to menstruate:\n1. She's underweight\n2. She's seriously ill, particularly with uterine disorders, but others things, too\n3. She's extra stressed-out\n4. She has a hormonal dysfunction\n\nAnyway, while having your period may seem like an inconvenience to you, it's actually one of nature's many ways of letting you know that your body is in working order. Trust me, you will miss your period on those months where she happens to be absent or late. And if you're sexually active, chances are you'll even freak out if she doesn't show up on time.

Its because of the endometriosis!

Actually, your period is precipitated by a steep DROP in hormone levels that induces shedding of the lining of the uterus. Hormone levels peak just around ovulation (i.e., mid-cycle), and only remain high if fertilization occurs (if there is a pregnancy). In a normal cycle, where there is no fertilization, hormone levels drop steeply and this causes menstruation.

Your answer is NO. The blood in a normal menstruation comes from the most internal layer of the uterus (Endometrium). At this step of the cycle, the Endometrium is very thick and because the lack of hormones (Estrogen's and Progesterone) it starts to break down and causes the bleeding. Most of the menstrual material are composed  of cells from the endometrium and blood from very small blood vessels. You have to keep in mind that heavily exercise causes a decrease in the release of Estrogen's and that could cause amenorreic cycles.\n\nOf course there could be some factors contributing on a Menorrhagia like low platelet count, low serum iron or calcium, or even because of some drugs such as NSAID of Anticoagulants amoung others. \n\nBut in a healty woman with normal platelet count, no bleeding disorders  and free of drugs, there is no relation between lifting heavy objects and menstrual hemorrage. But there could be a relation with a Transvaginal bleeding (Not Menstrual bleeding) because of the increase in abdominal presure, blood presure, etc.

some women have a tilted uterus, and occationaly it can cause you to have a pause of days in your period, but you should call you gyn just to make sure...it will matter how heavy it is, if its REALY heavy, i would call today...

Stress is often a key factor when women experience either absence of menstruation or abnormal bleeding. Hormonal imbalances caused by stress may proliferate the symptoms of fibroid tumors and endometriosis, as well as make pregnancy difficult to achieve for couples with fertility problems.

Hormonal imbalances.  Usually caused by diet.  If you are too thin, you may not have enough body fat - it's actually the cholesterol in your body (fat) that is used to make estrogen.  Fatter women tend to look "softer" or more feminine.\n\nEstrogen is used to make the lining of your uterus that you shed every month.\n\nBut progesterone is used to coagulate the lining so it sheds at a regular time period.  It's released after the egg is released, so it gets higher just before your period.  \n\nCertain foods can interfere with the balance of estrogen and progesterone.  Soy foods are particularly high in estrogen and can throw things off balance.  Progesterone is also released from the adrenal glands, which also release cortisol - a stress hormone.  Too much stress makes the adrenals concentrate on releasing cortisol and not on progesterone.  Again, things get out of balance.\n\nTry to eliminate soy products (and they are everywhere - most "vegetable oils" are soy oil) and see if that helps.  Do some deep breathing and meditation to relax and reduce the cortisol levels.

It can be caused by stress.  even if you don't think you are stressed there could be something that is bothering you just enough to screw up your cycle!  Also age....When I was younger my cycles were so heavy, but now that I am almost 30 it has started to slow down.

There are so many different things that could be causing abnormal bleeding. You should see yur gynecologist ASAP. I'm 42 and was having the same problem My gynecologist found fibroid tumors. Had a hysterectomy which removed the tumors(which were benign as in most cases).\nBut could be anything as simple as dieting, stress, etc.\nTrust yur gyn and go see him/her

Symptoms, such has heavy painful periods may be caused by a hormonal imbalance, could be caused by adenomyosis (bought on by uterus muscle and tissue being damaged, effected by the TL surgery impairing the blood supply to areas of that organ/muscle) or a combination of both.  Pain also can be caused by retro bleeding backing into the sealed fallopian tubes.\n\nThere is a lot more information on the web site www.tubal.org/symptoms.      I would also suggest you contact your doctor.

The "cause" is sexual attraction and hormonal secretions.  The RESULT can be pregnancy or total satisfaction.

Depends on where the pain is.  Often a small amount of a hormone gets released during your period called "Relaxin".  its job is to make the ligaments looser in case you become pregnant.  If some of the ligaments are already strained from stress placed on them, then the nerves that register pain may be activated.  Cramping of the uterus as it tries to expel the blood may also triggers pain receptors in the spinal column if it gets too intense.

I always had trouble with my left leg when you have your period your ovary enlarges which can then put pressure on the nerve that runs to your leg. Thats what the doctor said was causing mine. There is nothing you can do for it except pray for early menopause.

Roxylee, I'm not a doctor but if I may, it could be that the low estrogen and progesterone levels just before your period are responsible for PMS.  One of the PMS sequellae is URI.  Does this explanation make sense to you?

Because it sucks to be a woman sometimes.  Your uterus sheds its lining when you are on your period.  It can not come out all at once this would be too traumatic to the body.

i have the same problem...it might be because your due to have your period...has this been going on or has it just started? if it has been going on for a while its most likely because your due for your period. it might also be because your taking in too much cafeinne (cant spell it) so try to cut back and take a calcium suppl. or primrose oil suppl.
