I studied in the US and developed this during my late 20s. It went undiagnosed for years even though I was in Boston going to the best hopitals. About 6 years ago searching my symtoms I realized that I have a celiac and asked for a blood test and I was confirmed. Since then I moved back to Korea and I am constantly glutened and Seoul University hospital which is supposed to be best doesn't even have a proper antibody testfor celiacs disease and I am left to fend for myself. :/
