I know this is an old thread, but I just got diagnosed with the same thing, only no matter how much I eat, I don't seem to gain much weight. I wouldn't say I'm always hungry, but I never feel full. I feel like I could eat forever and still want more.
My TCM practitioner suggested that I get checked for parasites as well. She thinks its probably unlikely, but she would like to rule it out for certain.
As for treatment, I'm just starting tomorrow and she mixed herbs for me. I take them twice a day for 10 days, then return.
What treatment did your wife undertake in the end?
