To ask if this could affect my period

[yorkshireterrier32]

I did post this in general health but got no responses. I am currently 9 days late on my period and quite definitely not pregnant.

It’s usually fairly regular.

My BMI is currently 18.8 and I have lost 18 lbs since around September due to essentially barely eating most days. I’m not underweight obviously and I always thought that it was a low bmi that caused periods to be missed but could rapid weight loss cause it?

To be honest, I don’t even know if that is rapid weight loss, it’s more that I haven’t been eating enough.

Regardless of your weight, not eating properly could certainly affect your periods.
Can I ask why you aren't eating enough?

Yes it could affect your period. Mine is very sensitive to weight changes, whether it's a loss or gain.

Not eating enough, and rapid weight loss can put your body under stress.. which can affect your periods.
I agree with the PP asking why you are not eating enough. It sounds like you have bigger issues than your period being late.

Whoops, didn’t mean to enable voting.

@laalaaland lots of reasons but mostly stress.

well, stress is a major factor for changing your periods.
Are you getting support IRL?

Stress can affect your periods, not eating and rapid weight loss can also cause cycle changes - to be honest at 18.8 BMI you’re barely scraping into the healthy weight category.

Is the stress something that can be changed or managed to allow you to eat properly and feel healthier?

@laalaaland not really, no. I’ve never had a particularly healthy relationship with food but have been able to ignore it mostly.

I can’t see it changing as it’s the nature of my job and also just an ongoing situation outside of work, but I have registered myself for some counselling as it’s useless not trying to be proactive!
