I suffer with nauseaus and gas pretty well constantly  My internals feel so swollen and sore.  I feel tense and stressed with it.  My sleep pattern is very poor as I feel  much worst when I am laying down.  I have lesions on my liver, cysts on my gallbladder  and polyps in my kidney.    Some times when my condition really gets disccomforting I feel a  nauseaus and a hungery nawing feeling in my stomach and then  very gassy feeling it settles in my back just under my shoulder blades.  This is very uncomfortable and I cant lie down I just keep walking around I feel so nauseaus and feel like I am full of gas that is lodged in my back and is unable to free it self.  This issue always lasts 6 hours.  I have to be very careful  of what I eat the next morning as sometimes it will start up again.  IIhave had this  conditionfor a long time and it is interferring  with me having a good quality of life.. ..  I have had blood test and a few other tests but nothing has been determined. I am having a a gastroscopy in December of this year.  I am wondering if I may have symtons of stomach cancer or some other type.    I know this is hard to determin but have you any suggestions on what  I could be doing?

Hello, Thanks for the query to Chat Doctor. Forum. Cyst on the gallbladder, it is not very clear at which part, this cyst is having, please mention. As far as concerned about nausea, gassy stomach, vomiting. May be due to hyper acidity, gastritis, tension, indigestion, Fatty food (not digest due to cyst in gallbladder). May be due to ulcer in stomach. These symptoms didn't indicates towards cancer of stomach. Consult a physician/ surgeon (stomach problem & gallbladder) and get their opinion and help. Hope I have answered your question. If further any question I will help. Good luck.
