Menopause symptoms and the associated signs of menopause are part of a woman’s natural reproductive cycle. Most women will have at least one of a variety of menopause symptoms at some time before, during or after the menopause.
During the early teens, your ovaries will start releasing an egg every month. If the egg is fertilized, pregnancy occurs. If there is no fertilization the egg dies. The uterine lining (endometrium) which was built up in preparation for pregnancy, breaks down and is shed – menstruation. There are 4 main hormones involved in the menstrual cycle:
- follicle stimulating hormone (FSH)
- luteinizing hormone (LH)
The two that concern you most with regard to signs of menopause and symptoms of menopause are estrogen and progesterone. The menstrual cycle can be divided into 3 parts:
In the pre-ovulatory phase, the developing egg releases a lot of estrogen. This makes the endometrium grow and thicken. In the post ovulatory phase, progesterone is secreted in increasing amounts from the corpus luteum which is left in the ovary after ovulation.
It acts to increase the blood supply to the endometrium making it water-logged and rich in nutrients. If pregnancy does not occur, the corpus luteum dies through lack of stimulation from a growing fetus. Following this, the secretion of estrogen and progesterone declines.
The endometrium does not have enough hormonal stimulation to thrive and starts to break down shedding the top 2 layers and leaving the basal layer intact. This is referred to as menstruation. In the absence of pregnancy, this cycle occurs roughly every month (22-35 days).
There is a limited number of eggs in the ovaries and as you get older, more and more of them die off. By the time you’re in your 40s, most of the eggs have been released during ovulation or died and the few that are left are usually of poor quality. Ovulation may not occur every month and the length of the menstrual cycle gradually increases. Menstruation becomes irregular until eventually periods stop altogether.
During this time of irregular ovulation/menstruation, there is a lot of variation in estrogen and progesterone levels. Estrogen levels tend to be higher than those of progesterone, leading to the use of the term ‘estrogen dominance’ to describe this imbalance. Without a corpus luteum there is very little secretion of progesterone.
However, estrogen is still produced (in the fat cell for example) from conversion of androgens (male sex hormones) produced by the ovaries and adrenal glands. Menopause symptoms and menopause signs are thus caused by several factors:
- imbalance between estrogen and progesterone
- progesterone deficiency
- estrogen deficiency
The following list of menopause symptoms and menopause signs is very long and far from exhaustive. Fortunately, no woman will have all the menopause symptoms and signs and some women are fortunate enough to have relatively mild menopause symptoms.
Hot flashes / hot flushes
Hot flashes (or flushes) are the most common menopause symptom. They affect up to 85% of perimenopausal and menopausal women. They may be more severe in women who stop producing estrogen suddenly and in women who have surgical menopause through removal of their ovaries. Even if the uterus is removed without removing the ovaries, changes in blood supply to the ovaries may mean that they don’t function properly.
This is also known as nocturnal hyperhydrosis and involves waking up at night to find yourself drenched in sweat.
Normal periods may change during menopause. the time between each period may become much shorter or longer. The period may be absent for a couple of months. The flow of the period may also become heavier or lighter.
The lining of the vagina becomes very thin and fragile making it irritated and sore. It also loses its elastic nature and can’t stretch the way it used to. Estrogen and progesterone help to keep the vagina healthy. Without them, the vagina eventually shrinks, a process called vaginal atrophy. It also makes intercourse uncomfortable and even painful.
Other menopause symptoms include
- chest pain
- sore breasts
- itchy vulva
- loss of sex drive
- slower sexual arousal
- abdominal bloating
- irritable bladder
- frequent bladder infection
- frequent urination
- increased facial hair
- thinning hair
- itchy skin
- brittle nails
- pins and needles
- sore muscles
- stiff/swollen joints
- back pain
These menopause symptoms occur at various times. Early symptoms of menopause include irregular or heavy vaginal bleeding while menopause symptoms like thinning of the hair and brittle nails may not occur for several years after the menopause.
The herb black cohosh is used by many menopausal women to relieve symptoms of menopause especially hot flashes and night sweats as an alternative to estrogen/progesterone hormone replacement therapy.
However, the results of a study published recently found that it was no more effective than placebo (usually an inactive sugar pill) for treating menopause symptoms.
Should this worry you? Probably not! There’s been some criticism of this study. Only one brand of black cohosh was used. Effectiveness of the herb can vary depending on how it is extracted. The two best studied black cohosh extracts are those found in Remifemin and Klimadynon and these have been found to consistently improve menopause symptoms. Also, black cohosh wasn’t found to be harmful to the women that took it.
Black cohosh may not work as fast as HRT but it does not have estrogenic effects which is great for women who want to avoid estrogen. So if you’re using black cohosh and it’s working for you, keep doing what you’re doing – well, until another study tells you otherwise!
Increased heart risks with severe menopause symptoms
Women who have severe menopause symptoms are more likely to develop heart disease according to a recent study. Those who had the most hot flushes and night sweats had higher cholesterol levels, higher blood pressure, higher BMI and a higher risk of developing heart disease over the next 10 years. It is possible that the deficiency in estrogen that leads to the hot flashes may also have a negative effect on the cardiovascular system.
Seeing as research has shown that taking hormones to reduce the risks of heart disease has shown that it does the opposite over time, taking HRT to prevent heart disease is not a good idea.
The only other option is a healthier lifestyle – a balanced high-fiber diet and 20-30 minutes of exercise at least 3 times a week even before menopause.
Breast cancer survivors, yoga and menopause symptoms
Breast cancer survivors often have problems when it comes to managing menopause symptoms. Use of hormonal therapy may lead to a relapse of the cancer. In addition, some of the medication used to treat breast cancer can themselves worsen menopause symptoms.
According to a recent US , breast cancer survivors can find relief from menopause symptoms like hot flashes, through yoga.
The “Yoga of Awareness” program included stretching, breathing exercises, meditation and group discussions.
“Yoga of Awareness” is based on traditional yoga techniques that go beyond the teaching of specific postures to incorporate practices aimed at reducing stress and creating a heightened sense of awareness and acceptance about one’s physical and mental state.
The beneficial effects included:
- reduction in frequency and severity of hot flashes,
- fewer sleep disturbances
- less joint pain
- more energy
