Can untreated cushings disease eventually cause low cortisol?
Hi all,
I have a 6.5mm pituitary tumor found in 2018. I had always been 30-40lbs overweight and had a very round face. In 2020 and 2021 I was unemployed and had no health insurance. I went to Mexico and did 2, 24hr urinary cortisol tests. The first in November 2020 came back at 972, well over 3x the normal range. And then in January 2021, I repeated the test and it came back as 998. I was certain they would refer me to surgery and they didn’t. The endocrinologist (who was the best in Mexico City at the time) said to never let anyone operate on me. He put a CCG (continuous glucose monitor) on me for a week and said I had insulin resistance and gave me a GLP-1 and metformin. The GLP-1 was early in its class, you had to inject daily. It made me so sick I had to stop in 1 week. Metformin let me lose 30lbs then my liver acted up and they told me to quit. I gained back 40lbs.
I’ve been pushing for surgery since 2020 to no avail. In 2024, I got on tirzepatide and I’m at a normal weight now. I have decent muscle (I used to work out a lot) but now I think I have developed LOW cortisol. I have debilitating insomnia and I can hardly workout like I used to. Im 31 now. I have very bad mental health now, driven by chronic sleep deprivation. I wanted to ask if anyone has experienced this or if that’s even possible?
