What can cause severe stomach ache and nausea?
Patient: Each month, for about a year or more now, I experience severe stomach pain that induces nausea, and it is starting to concern me. It feels like a blunt kind of pain, and at times I think it’s gas or a need to use the bathroom for number two, not to be gross. I struggle with constipation and it often resolves itself in the form of painful diarrhea. These past two months, I noticed that this pain came the same day I tried new foods that did not particularly sit well with me. I think that may have something to do about it, but what about the other months? I just noticed today that I’m mid-cycle and ovaluating, which made me wonder if PMS has something to do with this? I never get these pains when I’m having my period or on the days surrounding it. I would appreciate input, as this is starting to overwhelm me. Doctor: Hi,  The most likely issue of altered gut flora mechanics with hormone imbalance.  Upper GI endoscopy and basic lab tests including thyroid hormone levels are mandatory here to get checked completely.  Hope I have answered your query. Let me know if I can assist you further.
