I go to langhorne office. Ive seen dr chan or cheng 20 yrs ago. I found office in langhorne. After going to multiple GI drs everywhere. Dr LEFTON had figured out wat was wrong w me. I have EPI. My pancreas dont work/make enzymes to digest food. I looked 12 months prego i was full of bad bacteria. My head was a mess from no nutrition. Im off head meds n others. I still swell all over still esp when i eat anything i am on enzyme thearpy. One of the GI dr i seen b4 Lefton told me i was just gettn fat. Only in my belly?? Im in a size 3. Size 1 when i seen that crack pot dr. I just got Dx w Lupus. So that is a big factor also. Dr Lefton is a very good dr. I have ref many ppl to him. My b/f mom. She now can eat certain foods. Shes not so sick. Shes getting better as well. I thank him so much for watching over my belly :)...
