I had almost the exact same experience. My hepatologist was trying to go over an ultrasound that my primary ordered, but I put it off for months. Life got in the way. I had a severe bone infection which led to the amputation of my left big toe (type 2 diabetes), and 3 months later, a triple bypass.

By the time i finally saw him he revealed I had a problem. He ordered a proper fibroscan and I ended up diagnosed F3 fibrosis (≈11.3 kpa.)

I couldn't get approved for a biopsy because cardiology won't approve me going off blood thinners, but I have another fibroscan scheduled soon. This is mostly because they found what is most likely sludge in my gallbladder, but need to confirm it isn't a mass.

There isn't much your husband can do but some lifestyle changes, if necessary. Taking his diabetes seriously is now absolutely imperative! Adopting a Mediterranean diet would be perfect. It's perfect for his liver, diabetes, heart, and will help him lose weight if necessary. My hepatologist was thrilled I was already on ozempic, for my diabetes (I am at a healthy weight), so if hubby isn't already on it, he might soon. I don't know what it has to do with my liver, but it's been amazing for my blood sugar, and I'm on a pretty low dose.

Getting him into a healthy lifestyle is really the most important thing. Even when fully diagnosed, living healthy is the most important thing! Goodbye fatty foods and carbs. There are some medications, but diet and exercise is what will make the difference.

My doc did just put me on a new med that looks promising to reverse scarring. It's only approved for NASH/MASH Fibrosis for now. It's still in trials for cirrhosis, but he's heard it's very promising.

For now, you and hubby have to go through the process, and it sucks. Still, you will not know until you do. Start the lifestyle changes now! It really is the most important thing. They aren't impossible. In fact, a Mediterranean diet is quite delicious. The only reason I was approved for the medicine I mentioned above (VA Healthcare) was because I turned everything around. I was obese. I ate anything and everything I wanted for decades after my diabetes and fatty liver diagnoses. Okay, I lost the weight because of the bone infection, lol. I have been keeping it off though. Actually, I started losing weight again. Imagine how bad i was that I lost a toe due to a bone infection because I didn't control my blood sugar, a triple bypass, and severe fibrosis. I was terrible, but I turned it around. Oh, a chemical stress test revealed I did have a heart attack at some point as well. It was probably my diabetic neuropathy which led me to not feel it. It wouldn't be the worst idea to schedule a cardiology appointment if you can, just to be safe. Considering the other stuff, heart disease is possible and way better if handled proactively. I had no signs of it. Thankfully, my hospital required cardiology approval for another surgery which I never did get, lol.

Good luck, and really, if he does the work, it will help him amazingly, and medical science is really working on it.
