|Why not menstruating ? (Absent Menstruation)|
Reasons You Might Have a Late Period—Other Than Pregnancy
If your period shows up like clockwork each month, being even a few days late can make you jump to conclusions. These are the most common reasons for an absent period.
Unless you're trying for a baby, getting your period regularly is both a blessing and a curse. On the one hand, you have to deal with cramps, bloating, and mood swings. On the other, yay, you’re not pregnant! Suddenly your missed period when babies aren’t on the agenda can be a real freak-out moment, but there are a few other factors that may be to blame. Here, ob-gyn, M.D., co-author of V is for Vagina, offers potential reasons you have a late period that have nothing to do with a bouncing bundle of joy.
The first reason - you are pregnant
Sometimes a late period means exactly what you think: There's a little bun in the oven! Because early pregnancy symptoms like abdominal cramping, bloating and breast tenderness are similar to what you may experience in the days before menstruation, it can be difficult to tell if your period is simply off by a few days or you're pregnant. If your period is late and you've had unprotected sex, take a home pregnancy test. A week after the date you expected your period gives the most accurate results, but many home test manufacturers promise to detect human chorionic gonadotropin (better known as hCG, the hormone released during pregnancy) sooner.
The second reason - you have experienced stress
A big scary event in your life can cause hypothalamic amenorrhea. "This particular area of the brain, the hypothalamus, is where a lot of the hormones for your period are regulated," says Doctor. "The hypothalamus is very affected by stress." So if you’re dealing with a big move, death in the family, huge breakup, or any other life event that's shaking you up, it could be the cause of your late period or missed period.
The third reason - you are sick
Think back to the time you should have ovulated. If you were sick, whether with a simple cold or something more serious, the stress could have put your body into that “which function is most important” phase mentioned above. So ovulation could have been delayed or didn't happen. That means your period will also be late or nonexistent. If illness around the time of ovulation caused your skipped period, Aunt Flo' will likely return once things are back to normal.
The fourth reason - you have polycystic ovaries (Polycystic Ovary Symptom)
PCOS is a hormone imbalance that comes down to a lack of ovulation, so you have altered levels of estrogen, progesterone, and testosterone. "We’re seeing a lot more of this, although there are varying degrees. It can cause you to completely miss your period or just not menstruate regularly," says Doctor. Other PCOS symptoms include hair growth in places like the face and chest, difficulty losing weight, and potential fertility issues. Your doctor can help you come up with a treatment plan to manage the condition.
The fifth reason - you violation of body weight
Your weight can affect your hypothalamus, a gland in your brain responsible for regulating various processes in the body — including your menstrual cycle. Extreme weight loss, a low caloric intake or being very underweight stresses the hypothalamus, and your body won't release the estrogen needed to build the lining of the uterus. The same happens with eating disorders like bulimia and anorexia, which also cause estrogen levels to dip too low. On the other hand, being overweight or gaining a lot in a short amount of time can cause your body to produce too much estrogen. The overload may cause you to go for months without ovulating or cause the endometrial lining to overgrow and become unstable, resulting in heavy, irregular periods. Usually, gaining weight if you're underweight or losing if you're overweight should help your periods to return to normal.
The sixth reason - Your Birth Control
A missed period or late period can actually be a harmless byproduct of the measures you take to avoid pregnancy. "Some low-dose pills will cause a lack of menses that isn’t dangerous and is many times a welcome side effect," says Doctor. The same goes for methods like hormonal IUDs, implants, or shots. It can also take some time for your period to come back if you've stopped birth control, but it will usually resume without issue in a few months.
The seventh reason - excessive exercise
Of course working out is good for you. However, when you overdo it (and possibly also restrict meals to lose weight), your body doesn't produce enough estrogen to complete the menstrual cycle. Some women — such as ballet dancers, gymnasts and professional athletes — are at greater risk for amenorrhea (missing a period for three or more months in a row). But you don't have to be a pro for exercise to mess with your periods. Working out excessively without taking in enough calories can cause disruptions. Some signs that you're overdoing it include extreme or rapid weight loss; decreased physical performance; or forcing yourself to work out through injury, illness or severe weather. Slowing down a bit and, if you need to, gaining a little weight should get things back on track.
The eighth reason - Premature Menopause
When women under 40 have hormones misfiring in a significant way, they can go through premature menopause, also known as premature ovarian failure. Along with a missed period, signs of it include hot flashes, night sweats, and vaginal dryness. "This isn’t very common, so you shouldn’t immediately worry about it," says doctor. If your gyno rules out the many other potential causes and thinks this may be the culprit, she’ll clue you in.
It is important to know about menstruation
Menstruation, also known as a period or monthly, is the regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina. The first period usually begins between twelve and fifteen years of age, a point in time known as menarche. However, periods may occasionally start as young as eight years old and still be considered normal. The average age of the first period is generally later in the developing world, and earlier in the developed world. The typical length of time between the first day of one period and the first day of the next is 21 to 45 days in young women, and 21 to 31 days in adults. Bleeding usually lasts around 2 to 7 days. Menstruation stops occurring after menopause, which usually occurs between 45 and 55 years of age. Periods also stop during pregnancy and typically do not resume during the initial months of breastfeeding.
Up to 80% of women report having some symptoms prior to menstruation. Common signs and symptoms include acne, tender breasts, bloating, feeling tired, irritability, and mood changes. These may interfere with normal life, therefore qualifying as premenstrual syndrome, in 20 to 30% of women. In 3 to 8%, symptoms are severe.
A lack of periods, known as amenorrhea, is when periods do not occur by age 15 or have not occurred in 90 days. Other problems with the menstrual cycle include painful periods and abnormal bleeding such as bleeding between periods or heavy bleeding. Menstruation in other animals occurs in primates, such as apes and monkeys, as well as bats and the elephant shrew.
The menstrual cycle occurs due to the rise and fall of hormones. This cycle results in the thickening of the lining of the uterus, and the growth of an egg, (which is required for pregnancy). The egg is released from an ovary around day fourteen in the cycle; the thickened lining of the uterus provides nutrients to an embryo after implantation. If pregnancy does not occur, the lining is released in what is known as menstruation.
