Perimenopause effect on UC?

Hi all,
I've had UC for about 18 years. I've been lucky enough to have some multi-year remissions between major flares, although there have been smaller flares interspersed as well. I take sulfasalazine for maintenance and add in Rowasa and steroids as needed.
I had a colonoscopy in January that sent me into a flare (first time that has happened and I have had many many colonoscopies.) A combination of increasing the sulfasalazine, Rowasa and Uceris has gotten me back to moving towards healing, but every time I try to go off the Uceris, the flare comes back. This is a new pattern for me - in the past, once the meds switched me over into healing mode, the flare would gradually resolve.
I'm in my late 40s and have definitely started the wild hormonal swings of perimenopause and I'm wondering if this is exacerbating my UC. I have an appointment with my GI in a week and I know he's going to bring up Entyvio AGAIN - I have always resisted the bigger drugs. But if perimenopause is likely to cause a rough few years, I guess I'd be more open to considering an immunomodulator like Entyvio.
My question is: For those people who have been through the hormone festival of perimenopause and menopause, do you feel it affected your UC and, if so, how?
I'd love to get some input before my GI appointment, even if it's anecdotal.

Thank you for any input!

My last flare I couldn't get of prednisolone rectal foam, as soon as I tried my symptoms would start up again.
I was already on a Humira biosimilar every fortnight so I was upped to weekly injections which seems to be working and I've been able to drop the prednisolone foam.

I am the same as Countess -- I was already deep into peri menopause with wildly crazy hormones when I developed UC

I'm in my late 30s (diagnosed with mild ulcerative proctitis in my mid-20s around the time I went off an oral contraceptive, but I was also finishing a PhD in the humanities and had been subsisting on generic diet sodas, microwave popcorn, and apples--BLESS my poor microbiome). For years I've traced GI symptoms to my monthly cycle, although it's not clear whether it's more an IBS phenomenon or my UC. In the past few years, I also have a few days mid-cycle around ovulation time where things feel off, with left sided abdominal discomfort and generalized pelvic pain (incidentally, a CT found I have sacroiliitis, so the pain is likely inflammation in my joints). This is an obvious and regular pattern linked to hormonal shifts, so it wouldn't surprise me that the hormonal changes of perimenopause also have an effect.

If anyone finds sustainable help with the hormone effects, I'd love to hear about it.

Thank you for the good wishes, cathbrighton. I really struggled with starting Entyvio but am hopeful it will keep things stable if I’m one of the lucky ones for whom it works.

Doesn't mention UC specifically but interesting all the same.
