Did you know that long before urine testing for pregnancy was known to modern man, it was practiced in Ancient Egypt? According to an article in Egyptian Medicine, a woman in ancient Egypt was required to moisten barley and wheat with her urine every day. If the woman was pregnant they would both grow, while if she was not, they would remain the same. This was replicated in a laboratory and found to be accurate! Why did they not rely on the missing of period to determine pregnancy? This is not because they did not know the relation between menstrual cycle and pregnancy, but because they probably realized that there could be other causes for irregularities in the cycle, making it an unreliable marker of pregnancy.
4 Reasons Why you May Miss Your Period Other than Pregnancy
Weight Fluctuations: If you have recently gained or lost a significant amount of weight in a relatively short period of time, it may throw your menstrual cycle off balance. It is seen that if a woman's BMI dips below 18 or 19 or crosses the mark of obesity, a woman may miss her period. With weight gain a woman starts to produce extra testosterone which inhibits ovulation.
Stress: When the body is stressed, whether due to a physical reason like over-exercising or because of an emotional reason like the loss of a loved one, you may miss your period. The reason sited for this is an evolutionary one – when your brain and body are overworked, the message it receives is that there is a threat to its survival. It therefore prevents reproduction in a non-conducive environment.
PCOS: Polycystic Ovarian Syndrome is a disorder in which a woman's hormones are unbalanced leading to the formation of benign cysts or tumors in their ovaries. It is linked with the overproduction androgen and is hereditary. This condition may disrupt a woman's menstrual cycle resulting in no periods at all or extremely painful periods. It is treated by gynecologists by prescribing hormones that help create a balance in the body.
Early Menopause: The mean age for menopause in Egypt is 46.7 years according to a study published in the Journal of International Menopause Society. However, in some rare cases, a woman may be peri-menopausal in her thirties leading to the early cessation of menstruation. Premature menopause is diagnosed by testing FSH levels which will be higher than normal for a woman approaching menopause.
