 [ Symptoms ] mom has extreme fatigue and abdominal pain she is been to the doctor and her illness remains undiagnosed suggestions [ Disease ] i am sorry your mom is going through this she did the right thing in consulting a doctor however that is not the end of the story the fact she continues to have symptoms without a diagnosis means she should go back to her doctor many conditions can cause the symptoms you list some of those conditions can take a long time and a lot of testing to diagnose if you did not get an acceptable answer from your mother is health care provider before it is time to go back and get an explanation if you do not feel your mother is health care provider is giving you an adequate explanation for her symptoms then you can consider getting a second opinion i hope this helps
