Treating Menstrual Pain With Diet

Dysmenorrhea is the medical term for painful, crampy periods. It affects almost half of menstruating women. Yet despite the substantial effect on quality of life and general well-being, few women seek treatment, thinking it won’t help. Treatments are available, though–modern medicine to the rescue! There are surgical options such as neuroablation, where surgeons go in and attempt to cut or destroy the nerves leading to the uterus, or doctors can just take out the uterus completely. There are of course a bunch of hormones in pills and shots that can suppress the menstrual cycle as well.


Since the pain is caused by inflammation, anti-inflammatory drugs like ibuprofen are the most commonly used, achieving symptomatic pain relief in about two thirds of women. While effective, women using them need to be aware of the significant risk that they may cause adverse side effects. Though there are a bunch of non-drug, non-surgical treatments like acupuncture, the evidence for the effectiveness of these treatments is generally weak.


One of the latest advances in treatment involves the use of a single high dose of vitamin D. In a randomized, double-blind, placebo-controlled study the placebo did nothing–in fact, most women got worse. But the women who got the vitamin D all felt better. For more on vitamin D, see my series justifying my vitamin D recommendations, starting with Vitamin D Recommendations Changed and ending with Resolving the Vitamin D-Bate.



But wait a second. If it’s pain caused by inflammation, how about putting women on an anti-inflammatory diet? Thirty-three women suffering from painful periods were placed on a vegan diet for two cycles and experienced significant reductions in menstrual pain duration from 4 days down to 3 days and a significant reduction in pain intensity. Women also experienced improvement of PMS symptoms such as bloating.


This was a crossover study, so after two months eating vegan the women were supposed to go back to their regular diets to see if the pain would return. But the women felt so much better that when the researchers asked them to go back to their regular diet to test before and after, several women refused, even though they were required to by the study.


Doctors too often patronizingly think that patients simply won’t adhere to therapeutic diets, but when they surveyed these women during the study, they found that the women were having fewer cramps and were losing weight. They also reported increased energy, better digestion, and better sleep. This showed that you don’t have to be in some Ornish or Esselstyn study facing certain death after a heart attack to stick to a plant-based diet. It’s well accepted even when testing more benign conditions. (For those unfamiliar with the work of Drs. Ornish and Esselstyn, see, for example, my video Our Number One Killer Can Be Stopped or my blog post Heart Disease: There Is A Cure.)


I’ve touched on this body of work briefly in Plant-Based Diets for Breast Pain. Plants that may be especially helpful include flax seeds (Flax Seeds for Breast Pain) and the spice saffron (Saffron for the Treatment of PMS and Wake Up and Smell the Saffron).

Nice to be armed with info to be proactive, and if the patients only partially change their diets something's better than nothing. Thanks.

A long time ago (when I was 17) it was the best for me...Sadly I don't understand why that's so difficult for women to understand.

Well I drink Yarrow tea. It's quite common where I live. You add 3 teaspoon of dried yarrow to boiling water and let it simmer for 3 minutes. Then you drain it when it's cold and drink each day and night 3 days prior to period. It really works. Give it a try.

another great reason to become a vegan! cramps r hell, i have pills prescribed to me by the doctor but they only numb the pain not take it away completely. If it means no more pain i'm totally down for becoming a vegan, been meaning to anyway here's a great incentive
