Hi, the three conditions may not be related. For the pancreatic cyst, therapy depends on the size and the content of the cyst. And if it is causing any compressive symptoms. With the gallstones your mother may need removal of the gallbladder. Atherosclerosis, a disease where the 'fatty' material in the blood gets deposited in the walls of the blood vessels. Certain conditions such as diabetes, high blood pressure, smoking and sedentary lifestyle promote this. If this causes any obstruction to the blood flow then it needs to be treated. So, discuss the possibilities with your doctor. Good luck. Regards.
