Gall stone with hypertension and Diabetes. Why? -

My uncle recently had a laproscopic removal of his gall bladder because of a stone. Pre operative he was diagnosis with Hypertension and DM and interestingly both disappeared postoperatively. Hypertension could be assigned to the body reaction to the acute inflammation but how come diabetes. Is it because of the obstruction caused by the stone cause back pressure of bile and hepatic dysfunction. I know hepatic dysfunction will cause raise in blood glucose but it that related to the insulin deficiency and associated gluconeogenolysis. What explains this type of presentation? And is there any extra precaution to take in the future ?

Types of Diabetes Type 1-Less than 10% of diabetics have this type of diabetes.. This type of Diabetes is caused by an insufficient amount of insulin. An abnormal autoimmune process damages the pancreas islet cells. Both milk protein and viral particles have been implicated in triggering antibodies that cause the autoimmune damage to the pancreas islet cells. The treatment consists of replacing the insulin by injections of various types of insulin. Type 2 – More than 90% of diabetics have this type of diabetes. Cellular resistance to insulin causes this type of Diabetes. The muscle, fat, and other body cells do not respond adequately to insulin. Heredity, obesity and inactivity are implicated in causing the resistance. Treatment consists of increasing the amount of insulin and/or decreasing the resistance in the body cells to insulin. Treatment includes diet, exercise and medications. http://www.lordsday.org/diabetes.htm
