Amenorrhea (loss of periods) Information


There are many conditions in Western industrialised societies today that were unheard of, or at least very rare, just a century ago. The same conditions are still unheard of in primitive peoples who do not have the 'benefits' of our knowledge. There is a very good reason for this: They eat what Nature intended; we don't. The diseases caused by our incorrect and unnatural diets are those featured on these pages.

Dietary causes:

Bran; soya; strict vegetarian diet; low-calorie dieting; eating low-fat dairy; insufficient fat intake; excessive exercise.

What is amenorrhea?

Amenorrhea literally means 'the absence of periods'. This is the situation in girls before puberty, and it happens later in life after the menopause. However, amenorrhea in between those times (except during pregnancy) is abnormal and unnatural. The mistake often made is to diagnose amenorrhea as a distinct condition or disease and then treat it with drugs. But it isn't: It is a symptom of an underlying problem. There are several reasons why you may not have periods; most of them are caused by your lifestyle. This is the area to check first.

If your periods stop for no apparent reason, you may actually be quite pleased. Periods can be inconvenient, but this is not natural and, unless it is corrected, amenorrhea can lead to other problems such as osteoporosis later in life. Thus cessation of periods for no apparent reason should be investigated.

The most likely causes of amenorrhea are associated mainly with deficiencies of zinc and of iron. The absorption of both minerals is inhibited by cereal fibre (bran) and the fibre in unfermented soybean products such as soya milk and soya flour.

The best sources of iron is liver, red meat and egg yolks. For this reason, reduced intakes of red meat and eggs as part of 'healthy eating' advice also has had serious consequences.

Starving or low-calorie, low-fat dieting are also causes of amenorrhea. The abstract of the latest study from Harvard University, published online at the end of February 2007, is in the box below. This shows clearly that low fat intake is another prime cause of periods stopping.
Lastly, too little body fat, either because of anorexia or excessive exercise, is another well documented cause of amenorrhea.

BACKGROUND Dairy foods and lactose may impair fertility by affecting ovulatory function. Yet, few studies have been conducted in humans and their results are inconsistent. We evaluated whether intake of dairy foods was associated with anovulatory infertility and whether this association differed according to fat content.

METHODS We prospectively followed 18 555 married, premenopausal women without a history of infertility who attempted a pregnancy or became pregnant during an 8-year period. Diet was assessed twice during the study using food-frequency questionnaires.

RESULTS During follow-up, 438 women reported infertility due to an ovulatory disorder. The multivariate-adjusted relative risks (RR) [95% confidence interval (CI); P, trend] of anovulatory infertility comparing women consuming >/=2 servings per day to women consuming </=1 serving per week was 1.85 (1.24-2.77; 0.002) for low-fat dairy foods. The RR (95% CI; P, trend) comparing women consuming >/=1 serving per day of high-fat dairy foods to those consuming </=1 serving per week was 0.73 (0.52-1.01; 0.01). There was an inverse association between dairy fat intake and anovulatory infertility (P, trend = 0.05). Intakes of lactose, calcium, phosphorus and vitamin D were unrelated to anovulatory infertility.

CONCLUSIONS High intake of low-fat dairy foods may increase the risk of anovulatory infertility whereas intake of high-fat dairy foods may decrease this risk. Further, lactose (the main carbohydrate in milk and dairy products) may not affect fertility within the usual range of intake levels in humans.
