For most women, menopause is a normal process of aging. If a woman has had her ovaries removed by surgery or has had damage to her ovaries for other reasons, such as radiation therapy, she may become menopausal from that process.
Perimenopause, also known as the climacteric, includes the time before menopause when hormonal and biological changes and physical symptoms begin to occur. This period lasts for an average of three to five years.
Some women don't have any symptoms during menopause or only have a few symptoms. Others develop disturbing and even severe, disabling symptoms. Studies of women around the world suggest that differences in lifestyle, diet and activity may play a role in the severity and type of symptoms women have during menopause. Symptoms can be noticed for several months to years before the last menstrual period and can continue for several years after.
For most women, the diagnosis of menopause is made based on a woman's description of her symptoms and the ending of her menstrual periods. Laboratory testing is not usually needed.
PMS-sufferers are also frequently deficient in calcium, zinc and B-vitamins, particularly vitamin B6, and can often benefit greatly from supplementation.
Besides nutritional supplementation, women can help prevent PMS by making changes to their diets. Eating more foods rich in omega-3 fatty acids, like fatty fish and green leafy vegetables, is important since omega-3 deficiencies have also been linked to PMS.
