Most women experience some physical and emotional symptoms during menopause, caused by hormonal imbalance. Typically, a woman will begin to experience menopause symptoms around her mid-40 as her body's reproductive capability comes to the end.

Sleep Disorders
Waking many times during the night, tossing and turning, and insomnia, are all sleep disorders connected with menopause. Women going through menopause may find that their sleep is less restful and that getting to sleep becomes increasingly difficult. Research indicates that women begin to experience restless sleep as many as five to seven years before entering menopause.

In the past, doctors believed that interrupted sleep was a consequence of night sweats, but recent studies indicate that problems with sleep are not always necessarily connected to other menopause symptoms. Sleep disorders are a symptom of menopause in their own right, but it is important for a woman to distinguish if her unique sleep disorder is actually caused by hormonal imbalance, or if there is another factor behind it

Memory Lapses

Memory lapses are a normal symptom of menopause Women approaching menopause often complain of memory loss, memory lapses, and an inability to concentrate. Misplaced car keys, skipped appointments, forgotten birthdays, and missed trains of thought might seem like trivial occurrences, but these can be extremely distressing for women who have never missed a beat before. However, these memory lapses are a normal symptom of menopause, associated with low levels of estrogen and with high stress levels.

Memory loss affects most people in one way or another, and more often than not, it is only a momentary memory lapse; however, when memory lapses begin to become a regular occurrence, it is wise to seek medical advice to treat the causes, like hormonal imbalance, stress, or other more serious conditions.

Weight Gain

Weight gain is another sign of changing hormones Weight gain, specifically a thickening around the waist, is another sign of changing hormones levels during menopause. While some sources claim that menopause has nothing to do with weight gain, hormonal changes during menopause actually influence weight gain and redistribution of fat. For example, fewer circulating estrogen hormones lead the body to retain more fat cells as an alternative source of components of estrogen.

Also, low testosterone levels lead to a decreased metabolic rate, meaning that from menopause onwards women need fewer calories daily; therefore, women who continue to eat as before will gain weight by default. In this way, changes in diet and exercise are necessary to revitalize the body's metabolic rate and prevent weight gain during menopause, as well as treatments to target the underlying hormonal
imbalance.
