Hi, I had gone through your question and understand your concerns. First, blood fluctuations cant be related to gallbladder surgery and this is separate issue which should be evaluated by cardiologist. The other issue may be sign of postcholecystectomy syndrome syndrome which has all these symptoms and this occurs in about 5 to 40 percent of patients who undergo cholecystectomy, usually can be transient, and rarely persistent or lifelong. Symptoms include Dyspepsia, nausea, and vomiting, Flatulence, bloating, and diarrhea, Persistent pain in the upper right abdomen. Some individuals may benefit from diet modification, such as a reduced fat diet, following cholecystectomy since it may be more difficult for digestion of fatty foods. Postcholecystectomy syndrome treatment depends on the identified violations that led to it. Typically, the patient is recommended dietary restriction table with fatty foods, enzyme preparations, antispasmodics, sometimes oral ursodeoxycholic acid can alleviate the condition.
