Menstrual Problems

It is very common to experience problems with menstruation from time to time. These problems can be related to the length or frequency of your periods, the amount of flow, or to symptoms related to menstrual cyclicity. Some of these problems are of a serious nature and some are not. In this section, we will discuss the most common problems associated with menstruation. For a firm diagnosis and treatment, consult your physician.

Premenstrual Syndrome
Although definitions of premenstrual syndrome (PMS) vary, it is generally described as a cyclic problem, followed by a period of time with no symptoms. Symptoms are generally seen 7 to 10 days before the menstrual period begins and can vary in severity from cycle to cycle. These symptoms usually go away soon after the onset of the period. PMS symptoms include headaches, mood disturbances, constipation, food cravings, weight gain, and breast tenderness. Charting the menstrual cycle along with any PMS symptoms for 3 to 6 months will allow a woman to see if her problems are cyclical in nature. For more information on PMS, see the PMS section of this site.


Painful periods
The medical name for painful periods is dysmenorrhea. Menstrual pain can vary from a dull pain in the back or abdomen to severe cramping and lower abdominal pain. The pain is usually greater at the beginning of the period, and in rare cases can be accompanied by nausea and diarrhea.

If a girl experiences menstrual pain from her first period, it is referred to as primary dysmenorrhea. Primary dysmenorrhea is thought to be a result of uterine cramping and is not associated with a gynecological disease. Prostaglandin production causes uterine muscles to contract, which can be perceived as menstrual cramping. Primary dysmenorrhea can last throughout the childbearing years. If menstrual pain begins after a woman has been menstruating for a number of years, it is considered secondary dysmenorrhea. Secondary dysmenorrhea is far more likely to be caused by some other underlying disorder such as endometriosis.

Endometriosis, which is often characterized by painful periods, occurs when fragments of the endometrium (the tissue that lines the uterus) grows outside the uterus in places such as the lining of the pelvic cavity, the fallopian tubes, the ovaries, the intestinal tract, or, less commonly, in the vagina. Each month, these fragments of endometriosis grow like the lining of the uterus. However, because they are enclosed in the pelvic and abdominal cavities, the tissue cannot escape. This causes an irritation of the lining of the cavity, which can be painful. Another result of endometriosis is the formation of scar tissue, which can distort the normal pelvic anatomy. Endometriosis of the ovary can lead to the development of endometriotic or "chocolate" cysts. The curious thing about endometriosis is that the amount of disease does not always correlate with the degree of symptoms. For example, a woman that has a very small amount of the disease can experience a great deal of pain. The opposite is also true.

Endometriosis is a chronic condition that can persist throughout the reproductive life and typically regresses at menopause when hormonal stimulation stops. This causes the endometriotic implants to shrink and symptoms to subside. Treatment of endometriosis includes painkillers, hormonal medications and/or surgery. If there is a possibility that you are suffering from endometriosis, please see your doctor.

Most cases of dysmenorrhea can be treated with over-the-counter pain relievers such as ibuprofen, which block the formation of prostaglandins, thereby reducing contractions that can cause pain. Some women find that exercise also helps. If the pain is severe or very bothersome, your doctor can prescribe a different medication. If you think that you have dysmenorrhea, see your doctor.

Abnormal Bleeding

Infrequent Periods
The medical name for infrequent periods is oligomenorrhea. This term is used when a woman has normal periods (in regards to the amount and length of menstrual flow), but the interval between periods is greater than 35 days. Infrequent periods are common in women who just started menstruating, and during the few years preceding menopause. During the first two years of menstruating, it is normal to have infrequent periods. Thereafter, if your periods are still infrequent, a gynecologist should be consulted. Symptoms that can help your physician determine the cause of oligomenorrhea are marked weight changes, milky white discharge from your breasts, acne, hair on your face or chest, or hot flashes.

Too-Frequent Periods
Polymenorrhea is the medical term for normal periods that occur too frequently, meaning periods that occur in intervals that are closer than 25 days. Polymenorrhea is annoying, inconvenient and a sign that ovulation may not be occurring. If ovulation is found to be normal, polymenorrhea can be an indication of a uterine problem such as fibroids. Furthermore, excessive bleeding can lead to anemia. For all these reasons, consult your gynecologist for evaluation and treatment if you think that you may be suffering from polymenorrhea.

Mid-cycle Bleeding
Some women experience light bleeding or "spotting" for one or two days in the middle of their menstrual cycle. This bleeding is thought to be caused by a temporary drop in estrogen that occurs at ovulation. This is a normal process. To determine the existence of mid-cycle bleeding, a woman should chart her cycle over several months to confirm that the bleeding occurs at ovulation. However, if bleeding is occurring at any time in your cycle, consult your doctor.

Absence of Periods
Absence of periods, whether it is temporary or permanent, is also known as amenorrhea. If a girl has not had her period by age 14 but is undergoing pubertal changes such as breast development, underarm and pubic hair growth, and a growth spurt, the lack of menstruation is not yet a cause for alarm. However, a 14-year-old who hasn't shown any signs of pubertal development should be seen by a doctor. Furthermore, if by age 16, a girl has still not had her first period, even if she is undergoing the other normal pubertal changes, it is time to consult a gynecologist. This is known as primary amenorrhea. Women and girls who are very thin, obese, have eating disorders or who are involved in intensive athletic programs often have a delayed menarche.

If a woman has had periods in the past but is now without them, this is known as secondary amenorrhea. The most common cause of amenorrhea is pregnancy. If a woman is not pregnant, a cause must be identified. There are a number of hormonal conditions that must be eliminated such as thyroid disease, elevated prolactin, and premature menopause. Amenorrhea is also commonly found in women who are very thin, have an eating disorder, and in athletes who perform regular, strenuous activity. The uterus must also be considered as a possible source of the problem. Certain surgical procedures of the uterus and cervix may lead to scarring which can obstruct the menstrual outflow. If you know that you're not pregnant but you have not menstruated for three months, a consultation with your gynecologist should be arranged. If the amenorrhea is a result of low estrogen levels, it may put you at increased risk of accelerated bone loss and cardiovascular disease as is the case in a menopausal woman. Your physician will ask many questions and conduct the appropriate tests to determine the cause of the amenorrhea.

Heavy Periods
Periods that are unusually heavy or prolonged are medically known as menorrhagia. Medical textbooks define menorrhagia as a menstrual flow that exceeds 80 ccs of fluid. However, it is nearly impossible for a woman to quantify the amount of her blood loss. Therefore, if you have noted a marked increase in bleeding from previous cycles, if you are soaking through 1-2 pads in 1-2 hours, if you're passing large clots, or if you have been bleeding for longer than seven days, see your doctor. There are many possible causes of menorrhagia. Regular but heavy periods can be caused by structural abnormalities in the uterus such as endometrial polyps or fibroids, or clotting problems. If the bleeding pattern is irregular, it may be caused by the absence of ovulation which can cause dysfunctional uterine bleeding.

Menorrhagia is a common problem, especially in the first few years of menstruating and the last few years before menopause. It is generally not a serious problem, but it can be inconvenient. Also, if longstanding, it can lead to iron-deficiency anemia. Therefore, you should see your doctor if you are concerned that your periods are heavy.

Short or Scanty Periods
Short or scanty periods that last less than two days, are referred to as hypomenorrhea, and may be a woman's normal pattern. It may also be seen at puberty or when a woman is approaching menopause. Since estrogen is crucial to the growth of the endometrium, any condition that causes decreased estrogen production will result in hypomenorrhea. These conditions have been outlined above in the section dealing with amenorrhea. Rarely, surgical procedures that involve the uterus (such as a D&C can result in scarring of the endometrium. The scar tissue replaces the normal endometrium, and results in less menstrual shedding. You should see your doctor if the problem persists so that he or she can rule out the possibility that hypomenorrhea is the symptom of an underlying condition.

Dysfunctional Uterine Bleeding

Dysfunctional uterine bleeding is the name given to abnormal bleeding patterns that occur as a result of irregular or absent ovulation. This condition occurs when the ovaries continue to make estrogen without the cyclic production of progesterone. Therefore, the normal sequence of growth and sloughing of the uterine lining is disrupted and results in erratic vaginal bleeding that is unpredictable and alternates between heavy and light. This condition can lead to anemia. If you have any abnormal bleeding patterns, consult a physician for diagnosis and treatment.

Diagnosis and Treatment of Abnormal Bleeding
To diagnose the cause of abnormal bleeding, a doctor will evaluate the symptoms and medical history of the patient. A complete physical, including a pelvic examination, will be performed and laboratory tests, such as blood tests, biopsies, pap smears, and pelvic sonograms will help determine the cause. The treatment will depend upon the cause of the dysfunction as well as the patient's reproductive desires at that time. If she wishes to be pregnant, the focus of the treatment will be on promoting regular ovulation. If pregnancy is not an issue, the goal is to promote the return to a normal bleeding pattern. It is important to see a doctor if abnormal bleeding occurs so that serious problems can be ruled out or treated if necessary.
