Thank you for your response. I have been to a gastrointerologist. They did an endoscopy, a CT scan, and labwork to check CBC, liver enzymes, and checked fornrare liver disorders. They said liver enzymes are in the slightly elevated range and that I was negative for rare liver disorders. I do not have problems with constipation or diarrhea. It’s so weird. Mostly nausea, fatigue, loss of appetite, and weight loss. I’ve been to PCP, cardiologists (had a stress test and heart ultrasound and passed both), gastroenterologist, and I recently had an MRI of my head (checking for MS lesions due to fatigue). I see to be a mystery like many others here. I hope someone who had difficulty in the past could come back and give us “newer ones” an idea of how long this lasts or what the culprit was to cause this so we can all get better and help others that come after us.
