Pme due to Irritable Bowel syndrome

I’m 23 and the first 10 months when I started having s*x, I was very good at it, with no issue of PME or anything else and could hold my climax for as long as I wanted (30mins to 1 hour).

But after some time I was diagnosed with Irritable Bowel Syndrome and had a lot of stomach related issues like bloating and gastric issue.

Since then I started facing Pme and some erection issues as well and slowly this problem has gotten really bad, and I cannot even hold myself for 1 min.

As i feel better with my stomach, i started doing Kegels and running (I used to go to the gym regularly always), but there is no improvement on the pme.

Anyone with similiar experience or some advise?
