Lipase levels symptoms and conditions

I have been on Yasmin for a little over a year. I started taking it because I was experiencing severe PMS Symptoms. I was really happy with Yasmin because my PMS went away and my face cleared up. However, the last six months I have started experiencing a lot of stomach problems. I have constant nausea--feels like morning sickness. I'm sick if I eat but sicker if I don't eat. I've had anxiety, headaches, insomnia, gas, weight gain, and depression. I've been to see the doctor about my stomach--I had a blood test and my amalayse and lipase were both elevated (around 400--normal is 70). He assumed that it was my gallbladder, but after a CT Scan, Ultrasound and Endoscopy, they say my gallbladder and pancreas both look healthy. He's stumped. I'm wondering if it's the pill. I've tried to find research showing that the pill can increase amalayse and lipase levels but with little luck. There are a few rare cases reported. Anyone else experience this? I can handle the side effects, it's just the pancreatic function that I worry about.
