by boo

Well. I've been reading lots on this page for quite some time now, I wanted to know (like the title suggests) How does fasting effect a women's menstrual cycle? Does it even effect it at all?

When I did a three day cleanse, my period was two weeks early and very heavy for two weeks! I was scared because this has never happened to me before. If I remember correctly, my next period may have been a little off, but after that I was back to normal. I hope this helps.

P.S. I'm with you. If I had known, I never would have done the cleanse.

Detox/colon cleanse and missed period NEW
by: Anonymous

I did two weeks of psyllium fiber and one week of bentonite clay - I stopped because I came down with a cold and didn't get a period or pms and just spotted for 4 days - now it is a month later and I started spotting yesterday (on day 25) and bloating and cramping like it was a normal Day 1. How long does it take to get a normal period back?? I wouldn't have done it if I had know this would happen!

fasting while on period NEW
by: Nazia

I am fasting as we Muslim fast from dusk till dawn no food no water here in UK the hour is long at least 20.5 hours long!! I noticed though let me note to you is that we don't fast when your on period as you to be clean to fast but if it longer than 10 days then you can fast after 10 days if your still bleeding after 10 days you fast. I been fasting after my 10 days and I noticed while am fasting there's no sign of blood at all and then when I eat at 9:00 Pm my period comes back for like 4 hours as I haveto fast again as we only have 4 hours not fasting time. So fasting can affect your period even when your having period.

Irregular period NEW
by: Anonymous

I too just finished a juice cleanse. Mine was only a three day cleanse and on the last day, I got my period (two weeks earlier than I should have). My concern is that it is much heavier than usual and it's now day five (normal by this day, I hardly bleed at all). I'm concerned as to how long this will last.

I know how you feel NEW

I have tried 3 times now to do a juice fast. The first time was for 14 days and I was successful but it COMPLETELY messed my period up and it took awhile to get back on course. I have tried two more times since then with the exact same result. I have no idea why this would be the case and cannot really attribute it to any other causes.

extended fasting NEW
by: Anonymous

I am on a 40 day fast I have only 3 days left, when I was 4 days into the fast I had started my period a week early. Now I am near the end of the fast and am a week late my guess is that Fasting can stop your period.

Concerned NEW
by: Anonymous

I am fasting (water only) and today is only day 3 but my period is so much heavier than usual and I was worried about loss of iron and losing too much blood. I imagine that because my body is detoxing that is what is making the bleeding heavier too?
Any thoughts about if I should break this fast? I wanted to wait until my body started to naturally feel hunger again and then reintroduce fruit juice and then fruit and so on very slowly. But I am willing to stop fasting if it is dangerous to fast while menstruating.

I'm doing a 40 days fast and it will be over Friday the 17th, and my cycle has stopped. I'm not complaining, I feel better and healthier.

Is it safe to juice fast while menstuating? NEW
by: Anonymous

I too started a juice fast and got my period on day 2, one week earlier than I should have. My question is, is it ok to continue with the fast, or is losing blood and living on juice dangerous?

Early period
by: Anonymous

I started fasting and 2 days into it I began spotting. The bleeding got a little heavier each day but not a normal flow. I'm not expecting my period for about a week and a half. Is this ok?

Almost 2 weeks early...
by: Anonymous

It's good to know that I am not alone. I am starting Day 35 of a 60-day juice fast and my period came VERY early. My cycle averages 40 days in length. Since it started a couple of days ago, my cycle is 23 days. I am wondering if this cleansing and detoxifying is somehow normalizing my cycle. Hmmm.

Early menstrual cycle
by: Lindsay

I am doing a 14 day juice fast and I'm currently on day 9. I just got my menstrual cycle today but it is 2 weeks early. This never ever happens to me, but this is my first extended fast. Glad to know this is normal! :)

I guess it varies
by: Anonymous

I am water fasting and currently on day 5. I just got my period and it is 5 days early. So I guess my body knows better.

Effect of Fasting on Menstruation
by: LJ

I noticed whenever I do long juice fast (10 days or more) in a month, my menstruation is delayed. But when I go back to my normal diet - vegan, mostly raw - and eat regularly for the whole month, my period follows the 28 days cycle.

Fasting and menstrual cycle.
by: Anonymous


It will be longer periods and shorter duration, or will cease completely while you fast.

I used to know the scientific explanation years ago but I forgot it. Not to be concerned.
