Sounds like greasy foods are aggravating your stomach, so avoid the greasy foods.
Pay close attention to your diet and avoid foods that cause this.
If it persists, I would have GERD ruled out by your physician.
What would you suggest to help flush greasy foods out of my system? Detox?
It could be gall bladder related - before I had my gall bladder removed, I found that greasy foods definitely made my symptoms worse (pain, nausea, vomiting).
Try staying away from greasy foods for a while and see if it helps (I know that's sometimes easier said than done). Also keep a food diary to see if you can relate it to any other foods/drinks.
I'm not sure of what you might be able to take to help flush the greasy foods out of your system, other than increasing your fruit/veggies and fiber and drinking plenty of water.
I also would say, as mentioned above, if the problems continues, to check in with your doctor. He/she may suggest going to a gastroenterologist, but your primary doctor is a good place to start (you may need a referral to the gastro doc anyway, depending on your insurance).
I would not recommend any medication, etc. to flush the greasy foods out of your system; just avoid them.
Thanks for the advice guys
