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.

What are Some Common Perimenopausal Changes?

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
  • Other

Reduced Fertility

Women's fertility begins to decrease at about age 37, mainly due to aging eggs. The risk of spontaneous miscarriage increases to about 50 percent 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:

  • Caffeine
  • Alcohol
  • Hot drinks
  • Hot or spicy foods
  • Stress
  • 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 percent 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 percent of women. Surgery may be needed to correct anatomical defects.

Infections

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
  • Urinary incontinence
  • Irritability due to sleep disturbance
  • Medications for high blood pressure or depression that reduce sexual desire

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.

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

When Should You Be Concerned That Perimenopausal Bleeding May Not Be Normal?

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 Depo-Provera 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 or Induced Menopause on the website of the North American Menopause Society.

Mood Swings

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.

Other

In addition, women with mobility impairments may have increased problems during the perimenopause with:

  • Skin breakdown
  • Bladder spasms
  • Spasticity
  • Urinary dysfunction
  • Autonomic nervous system dysfunction, including autonomic dysreflexia
  • Intolerance to heat
  • Poor circulation
  • Fractures
  • Decreased physical functioning
  • Accelerated progress of chronic disease
