I am so glad to find this blog and to find I am not alone! I had diverticulitis first of August 2025 and thought all I needed was antibiotics and would be fine. I ended up so sick and in pain, sudden weight and muscle loss, This went on for 3-4 months before surgery. Thought it was going to take 3-5 hours for colon resection and removal of a fistula. Turns out there was a lot of inflammation, my rectum and appendix was removed, and they had to do muscle repairs. Surgery took 10 HOURS, a long time under anesthesia, plus I had anesthesia 3 times for colonoscopy and two sigmoidoscopy procedures! I have lost more than half of my thick fine hair! I cry over it a lot because my scalp is showing in several places. Globs of hair come out every time I gently wash or brush. I am scheduled to have an ileostomy reversal surgery in March…more anesthesia…and am scared I will lose what is left of my hair! Several friends have said it will grow back. I am 72 and don’t want to look like this the rest of my life. 😢
