Natural menopause occurs when you have had no menstrual periods for at least one year without being pregnant. Menopause occurring after surgical removal of the ovaries, or damage to the ovaries by medical treatment such as chemotherapy or radiation, is called induced menopause. The perimenopause is the transitional period lasting up to ten years from having normal menstrual periods to no periods at all. During this transition, you may experience no symptoms at all or some combination of premenstrual syndrome (PMS) and menopausal symptoms. Because most women experience menopause between the ages of 45 and 55, at an average age of 51, perimenopausal symptoms typically begin occurring throughout the 40's. You can expect to experience menopause at about the same time as your mother or older sisters unless you have certain chronic conditions or health habits that promote early menopause. These conditions include taking corticosteroid medications, smoking, or having an autoimmune or motor neuron disease.
The most common changes occurring during the perimenopause are:
- Reduced fertility
- Hot flashes
- Urinary and genital changes
- Infections, particularly bladder, vaginal, and skin
- Changes in sexual function
- Changes in menstrual periods
- Mood swings
Women's fertility begins to decrease at about age 37, mainly due to aging eggs. The risk of spontaneous miscarriage increases to about 50% by age 45. The risk of chromosomal abnormality in the fetus increases with each year to 1 in 40 by age 45. Women in their 40s tend to have more pregnancy complications such as premature labor, stillbirth, and delivery by caesarean section. The risk of such pregnancy complications is already higher in many women with disabilities. If you do not wish to get pregnant during the perimenopause, please be sure to continue using contraception, as pregnancy is still possible until complete menopause is reached.
Hot Flashes and Night Sweats
About two-thirds of all women have hot flashes, the most common symptom during the perimenopause. A hot flash or flush consists of a sudden hot feeling in the face, neck, and chest, blushing, faster pulse, and sometimes perspiration, often followed by a chill, lasting from three to six minutes. The most common duration of hot flashes is three to five years. Hot flashes that occur with heavy perspiration during sleep are called night sweats. Night sweats and hot flashes may interfere with sleep, as can falling estrogen levels alone. Inadequate sleep in turn triggers irritability and fatigue. Environmental conditions that may trigger hot flashes include:
- Hot drinks
- Hot or spicy foods
- Warm environment
Avoiding these conditions as much as possible will help reduce the number and severity of hot flashes.
Hot flashes may be worse for women with neurological disabilities such as SCI and MS due to preexisting vasomotor instability, also in women with joint and connective tissue diseases who take corticosteroid medications. However, all flushing is not necessarily menopausal in women with disabilities; it may be neurological in origin. The presence of other perimenopausal symptoms may help distinguish hot flashes from neurological flushing that will not respond to estrogen replacement therapy.
Urinary and Genital Changes
As a result of natural decreases in estrogen, the tissues of the vulva (outer genital area) and the lining of the vagina become thin, dry, and more alkaline, making them more prone to injury. Atrophic vaginitis, which is vaginal inflammation, not an infection, may result. You may notice redness, itching, irritation, and discharge. These symptoms should be examined by a physician to rule out other causes such as infection. Regular sexual activity will help prevent vaginal atrophy. Without treatment, this condition can cause painful vaginal ulcers that make sexual intercourse impossible. Vaginal lubricants may help mild cases, but prescription estrogen is the most effective for restoring the thickness and elasticity of vaginal tissues. A daily diet rich in soy foods may help reduce vaginal discomfort in a few weeks.
Urinary problems may occur when the lining of the urethra also becomes thin and the surrounding pelvic muscles weaken. More frequent urination, urgency when the bladder is not full, frequent nighttime urination, incontinence, and painful urination may result. If you already have some of these problems due to having a neurogenic bladder, they may become more severe with menopause. Smoking, drinking alcohol or caffeine, bladder infections, weakening of the pelvic muscles and ligaments due to previous childbirth or natural aging, and taking diuretics and some tranquilizers may also increase incontinence. As many as 40% of women aged 45-64 have urinary incontinence. Bladder studies by a urologist may be needed to determine the exact cause. Estrogen pills, patches, and vaginal preparations improve incontinence for 40-70% of women. Surgery may be needed to correct anatomical defects.
Women with mobility impairments, particularly due to MS and SCI, already have a high frequency of bladder infections. Taking antibiotics often in turn causes more vaginal yeast infections. Menopause increases the risk of infections by increasing the vaginal pH so that it is less acidic.
Changes in Sexual Function
Most women surveyed report that they experienced no changes or improvements in their sexual relationships with menopause. Many women remain sexually active even when very old. However, low hormone levels in midlife may lead to reduced sexual desire, or painful intercourse due to vaginal thinning, dryness, narrowing, and shortening. These conditions are often worse in women with disabilities. Women's sexual activity and interest during midlife may also be influenced by:
- Not enjoying sex while younger.
- Body image. Women with disabilities who accept changes in physical appearance such as sagging breasts and abdomen, wrinkles, and grey hair in addition to disability-related changes will feel more comfortable being with a partner. After surgery to remove a breast or the uterus, women may avoid sexual activity because they feel unattractive.
- Urinary incontinence
- Irritability due to sleep disturbance
- Medications for high blood pressure or depression that reduce sexual desire
Women with reduced sex drive may benefit from testosterone replacement, which greatly diminishes at menopause. Before menopause, testosterone is produced by the ovaries and adrenal glands; only adrenal production continues after menopause. Androgens such as testosterone are important for maintaining sex drive and bone density. If you have rheumatoid arthritis, testosterone may decrease your disease activity. Testosterone ESTRATEST may be prescribed, which combines estrogen and testosterone. Taking too much testosterone without estrogen may deepen the voice, cause baldness or facial hair, or increase muscle mass.
Changes in Menstrual Periods
During the perimenopause, the frequency of ovulation (egg release) decreases and hormone secretion by the ovaries becomes erratic. As a result, most women experience irregularities in their menstrual periods. It's a good idea to keep a record of the dates your periods start and stop, the amount of flow, blood clots, and pain. This record will help your health care provider distinguish what's normal from what's abnormal for you. Remember that every woman's cycle is different. Changes may include:
- Heavier bleeding
- Lighter bleeding
- Bleeding lasting fewer days than usual
- Skipped periods
- Cycle shorter than 28 days
- Cycle longer than 28 days
Any trend toward increased bleeding should be checked by your health care provider. In particular, any of the following changes may signify abnormal bleeding:
- Very heavy bleeding that gushes, often with a lot of blood clots; needing to change menstrual products every hour; needing 8-10 super napkins or tampons daily
- Bleeding after intercourse
- Spotting between periods
- Continuous bleeding lasting more than two weeks
- Less than two weeks between periods of bleeding
Following are possible causes of these abnormal menstrual changes.
- Fibroids, noncancerous growths in or around the uterus, can produce more bleeding or more frequent periods, as well as menstrual cramps, back pain, difficulty with bowel movements or urination, or pain during intercourse. Abnormal bleeding may be the only sign of possible fibroids for women with impaired sensation.
- Hyperplasia (excess growth) of the uterine lining or noncancerous polyps on the lining can increase bleeding.
- Cancer of the uterus, vagina, or cervix can cause abnormal vaginal bleeding. These serious diseases can be screened out by regular pelvic exams and Pap smears.
- Severe hormone imbalance between estrogen and progesterone secretion, usually too much estrogen with little progesterone, can cause heavy bleeding as often as daily.
- Hypothyroidism may produce very heavy menstrual bleeding. This condition often accompanies fibromyalgia or other autoimmune disease.
- Contraceptive devices such as an IUD, the Pill, the Norplant implant, or DepoProvera shots sometimes cause breakthrough bleeding between periods. However, birth control pills are often prescribed to stop irregular bleeding by reestablishing a regular, predictable, menstrual cycle.
If your health care provider decides that your perimenopausal bleeding is abnormal, there are several procedures that can determine the cause. These include endometrial biopsy, D&C, hysteroscopy, or transvaginal ultrasound. If your health care provider orders one of these procedures, you can find out more about it in the Menopause Guidebook by the North American Menopause Society.
Other causes of abnormal menstrual bleeding may be related to your disability. Women on long-term corticosteroid therapy for rheumatoid arthritis, lupus, lung disorders, or other chronic conditions often have hormone imbalances with irregular or heavy menstrual bleeding. After spinal cord injury, menstruation may cease from a few months to more than a year, sometimes permanently if the woman is near menopause.
What are the treatment options for abnormal perimenopausal bleeding?
The perimenopausal period is the most vulnerable time for hysterectomy, the surgical removal of the uterus. However, hysterectomy should seldom be the first treatment choice for abnormal bleeding. Depending on the cause of abnormal uterine bleeding, treatment options include:
- Nutritional supplements. If you have more bleeding than usual, take an iron supplement to prevent anemia. If you are feeling more tired than usual or having more frequent headaches, anemia may be the cause. Although dietary sources of iron alone will not be sufficient, increasing your intake of iron-rich foods such as beef, beans, and nuts will help. Taking grape seed capsules, 1,000 - 2,000 mg daily, may help decrease the amount of menstrual flow if capillary fragility is a cause.
- Hormonal medication. Your health care provider may prescribe a low-dose birth control pill or progestin to regulate heavy, long menstrual periods. Some perimenopausal women have benefitted from applying a natural progesterone cream to their skin during the two weeks before menstruation but some gynecologists disapprove of this option because the amount of progesterone actually absorbed is unknown. Other prescription hormonal drugs may be used for short-term treatment.
- Surgery. There are several different kinds of surgical procedures that can be used to remove fibroids or to destroy the uterine lining. The decision to remove fibroids surgically, and the surgical technique selected, depends on their location, number, and size, as well as whether the woman wishes to have more children. In the past, a D&C was often done to diagnose and treat abnormal bleeding. However, D&C was seldom effective. Today, this procedure is considered obsolete. If your health care provider suggests doing a D&C, or suggests hysterectomy before trying other options, get a second opinion. If a hysterectomy is necessary, a woman usually will not go through menopause unless the ovaries as well as the uterus are removed. However, removing the uterus alone may trigger menopause in older women. Young women may experience hot flashes and night sweats temporarily until the ovaries resume normal functioning. These women will still eventually go through the perimenopause, but without irregular periods to warn them of its approach. Menopause is immediate if the ovaries are also removed. To find out more about surgical techniques, see Surgical Menopause, which can be obtained from NAMS.
The folklore surrounding menopause dictates that menopausal women are moody and irritable. Many experts believe now that menopausal moodiness may be due more to sleeplessness and poor sleep caused by hot flashes and night sweats than to estrogen deficits per se. However, many women have reported an increased feeling of well-being after replacing estrogen. Estrogen can have an antidepressant effect due to its effect on brain neurotransmitters. Midlife stress may coincide with menopause and lead to depression and anxiety.
In addition, women with mobility impairments may have increased problems during the perimenopause with:
- Skin breakdown
- Bladder spasms
- Urinary dysfunction
- Autonomic nervous system dysfunction, including autonomic dysreflexia
- Intolerance to heat
- Poor circulation
- Decreased physical functioning
- Accelerated progress of chronic disease
Osteoporosis (bones less dense)
In addition to being a woman with a mobility impairment, past menopause, and getting older, other risk factors for osteoporosis are:
- Having an inadequate diet, particularly with too little calcium and vitamin D
- Getting little or no weight-bearing physical activity
- Cigarette smoking
- Heavy drinking of alcoholic beverages
- Having no menstrual periods while young for at least six months, as sometimes occurs with spinal cord injury
- Taking bone robbing prescription medications such as steroids or anti-seizure drugs
- Taking high doses of L-thyroxine for thyroid disease
- Premature menopause (before age 40) or menopause induced by surgery or other medical treatment
- Being small-boned or thin
- Having a family member with osteoporosis
- Being Caucasian or Asian
Clues that you might have osteoporosis are prolonged, severe pain in the middle of the back, change in the shape of the spine, loss of weight, tooth loss, and fractures.
The risk of heart disease increases for women after age 55. This risk may occur earlier for many women with disabilities. Your risk for heart disease increases when estrogen levels drop at menopause. Women who have heart attacks are twice as likely as men to die from them. Many more women die from heart disease than from breast cancer. In addition to menopause and getting older, other risk factors for heart disease are:
- Being more than 30% overweight
- High blood pressure
- Cigarette smoking
- Physical inactivity
- Abnormal cholesterol levels
- Having a close relative who had a heart attack or stroke before age 60
- Early menopause, before age 40
- Drinking more than three alcoholic beverages daily
- Being African American
The North American Menopause Society recommends considering the following when deciding whether a woman should use ERT/HRT or other treatments:
- Menopause-related symptoms
- Cardiovascular risk (heart disease)
- Osteoporosis risk (bone wasting)
- Breast cancer risk
- The woman's lifestyle
- The woman's view of each treatment option
- The woman's general health status
If you elect to replace hormones and do not have a uterus, you only need to replace estrogen (ERT). If you do have a uterus, progesterone must be added to prevent excess buildup of the uterine lining and an increased risk of uterine cancer (HRT). Estrogen with progestogen has proved to be as effective as estrogen alone in treating menopause symptoms and reducing risk of heart disease and osteoporosis. HRT can be taken as a combination pill or patch. Both hormones can be taken every day (continuous combined schedule), or estrogen can be taken alone most days with progestogen added for part of the month (cyclic schedule). Vaginal spotting and bleeding may occur during the first six months of HRT, especially on the cyclic schedule. You may elect to use micronized natural progesterone to avoid possible side effects from synthetic progestin such as lowering HDL, fluid retention, headache, breast tenderness, and alterations in mood. However, do not rely on over-the-counter progesterone creams to oppose estrogen replacement, as not enough progesterone is absorbed through the skin to protect the uterus against cancer. If you have a history of breast cancer, blood clotting disorders, or liver disease, you may not be a good candidate for HRT. Be sure to discuss with your health care provider the pros and cons in relation to your risk factors.
ERT/HRT will relieve hot flashes, night sweats, sleep disturbances, vaginal thinning and dryness, skin thinning and loss of elasticity, and urinary symptoms that are not caused by neurological or mechanical impairment. It can be taken orally or applied as a skin patch. An estrogen cream, ring, or tablet can be applied vaginally to relieve vaginal symptoms alone. Women tend to experience the fewest side effects with the estrogen tablet and are less likely to discontinue using it than the cream form.
Women who take ERT/HRT have a 35-50% reduced risk of getting cardiovascular disease compared to women who do not use it. Estrogen reduces this risk by raising HDL (good cholesterol), lowering LDL (bad cholesterol), reducing the growth of fatty deposits in blood vessels, and dilating blood vessels. Testosterone should not be added if you are at high risk of heart disease or have low HDL levels (good cholesterol) because it reduces HDL.
Menopause speeds up bone loss (osteoporosis), especially during the first decade after menstruation stops. Having osteoporosis, in turn, increases the likelihood of having fractures of the spinal vertebrae, hip, forearm, pelvis, and ribs. All postmenopausal women should have their bone mineral density (BMD) tested to detect osteoporosis. Calcium, 1200-1500 mg daily, will help slow down bone loss. Younger women should have BMD testing if they have a fracture from any cause. Even if you delay starting HRT until age 65, your protection against fractures will increase more than 60% compared to women who have never used HRT. Taking testosterone along with estrogen can promote new bone formation as well as preventing future bone loss. Other drugs such as rezindronate, alendronate, etidronate, calcitonin, or raloxifene may be taken instead for osteoporosis. However, these drugs will not help any other symptoms associated with menopause. You may also reduce your risk of osteoporosis by ingesting natural phytogestrogens, which are plant-derived, estrogen-like agents, or ipriflavone, a synthetic derivative. Phytoestrogens are plentiful in flaxseed, red wine, and soy products such as tofu.
HRT may offer additional benefits to women with disabilities such as multiple sclerosis and spinal cord injury. Estrogen substantially increases skin thickness and collagen content, which can prevent, or improve healing of, pressure sores. It may also improve urinary function by reducing the risk of infection, bladder spasm, and incontinence. Replacing estrogen may slow disease progress in MS and rheumatoid arthritis.
Breast Cancer Risk
When taken for long periods of time, more than 15 years, estrogen may increase the risk of breast cancer. Most health care providers recommend that women who have had breast cancer should not use ERT. Others believe that short-term use of HRT is safe for women who have a history of breast cancer. ERT does not increase the risk of breast cancer when this risk is entirely genetic. For most women, the risk of getting breast cancer is much smaller than their risk for heart disease and osteoporosis.
Other prescription drugs may be taken to relieve hot flashes, such as clonidine, progestogen, and megestrol acetate. Certain medications used to treat depression, such as Effexor, may be prescribed in low doses to alleviate hot flashes, even if you are not depressed.
If you and your health care provider decide that HRT is not a good choice for you, there are other remedies that may help reduce hot flashes and other menopausal symptoms. Of course, beginning with a healthy lifestyle is always the best insurance against severe symptoms. Following are some remedies that have the best evidence for effectiveness.
Vitamin E, at 400-1200 IU a day, can help reduce hot flashes, vaginal dryness, and the risk of fatal heart attacks. However, if you are taking anticoagulant drugs or aspirin, check with your health care provider first, as vitamin E can increase bleeding.
Calcium. Taking your calcium supplement at bedtime with milk may help you sleep, as it has a calming effect.
Soy Products, such as tofu or soy isoflavone extract, and flaxseed contain high levels of natural plant estrogens. Though this estrogen effect is weaker than that obtained from ERT, eating 60-100 mg daily of these products may reduce the number of hot flashes, lower cholesterol, lower blood pressure, and reduce the risk of breast cancer. It may take two to six weeks to note any benefits. Though proven to be highly effective for hot flashes, they provide very little benefit to your bones.
Black Cohosh is an herb that is used to treat hot flashes, especially in Germany, where it has been extensively studied.
Korean Ginseng is an herb that helps relieve fatigue and may prevent vaginal thinning.
Acupuncture was proven to relieve hot flashes for at least three months after each treatment.
Note that products labeled as natural are not necessarily safer or better than other products. "Natural" is a marketing term, and even some plants are poisonous. For example, do not confuse black cohosh with blue cohosh; blue cohosh is toxic. Since herbs may be as chemically potent as prescription drugs and interact with other drugs that you take, be sure to notify a health care provider about which ones you wish to use to determine their safety for you.
