Can having an eating disorder in your teens and 20s impact your hormones and digestive system at 40?

I was a daughter of the early 2000s when being ridiculously thin was “in” and I was an individual with a very competitive nature and extreme self loathing. Im now almost 40, struggling to get pregnant and fight constant nausea and hunger bordering on starvation. My stomach can literally only ever hold two bites of food at a time - its not cute, I’m frail and feeling sick most of the time. Does anyone else have experience with this? Is it likely just consequences of my years long ED?
