atypicalAtypical pneumonia that physical activity like stomach crunches can lead to GI symptoms - but still can happen. You may want to be evaluated for various causes of dyspepsia (i.e. an ulcer, GERD or inflammation of the upper digestive tract). You can consider an upper endoscopy or upper GI series for further evaluation.
If these tests remain negative, an ultrasound of the abdomen or a 24-hr pH study can be done to evaluate the gallbladder and for GERD respectively.
Irritable bowel is also possible - and should be considered if the testing remains negative.
These options can be discussed with your personal physician or GI consult.
Followup with your personal physician is essential.
