Shrinking in height: anyone else noticed this?

[Athena]

I went from 5'10" to 5'7" so I am happy about that

OK, y'all got me curious!

Just now, I went and measured myself. No change. 5 feet, 11.5 inches. < sigh >

In January, I'll have been on HRT for six years, and that was also the last time anyone checked my height.

My dad says that the reason I am tall is all those days as a teen, out in the horse corral shoveling manure in the summertime. All that sunshine and fertilizer must have done something.

Lori: lol your last sentence 

I've been looking at some academic studies and there seems reasonable evidence that estradiol has an effect on ligaments. This meta study is a useful resource: https://journals.sagepub.com/doi/abs/10.1177/03635465241310145

So even if the bones don't change, then as well as the tilt and posture issues mentioned above by several of you, the connecting tissues including cartilage and ligaments may well do, thus affecting the overall muscular-skeletal structure. It may explain why certain injuries are more prevalent in females than males e.g. ACL ruptures.

It appears that some of these changes may be associated with the hormone relaxin.

I'll add a caveat here: I'm not a medic or medical scientist and I've only been flicking through various sources.
