- Why would a cause of hyperinsulinism be hypoglycemia? Don’t lower levels of blood glucose inhibit of insulin rather than produce large amounts of it to result in hyperinsulinism?Diabetes mellitus is characterized by insufficiency of thepancreas to produce enough insulin to regulate the blood sugarlevel. In type I diabetes, the pancreas produces no insulin, andthe patient is totally dependent on insulin from an externalsource to be infused at a rate to maintain blood sugar levelsat normal levels. Hyperglycemia occurs when blood glucoselevel rises much higher than the norm (>8 mmol/L) for pro-longed periods of time; hypoglycemia occurs when the blood sugar level falls below values of 3 mmol/L. Both situations canbe deleterious to the individual’s health. The normal range ofblood sugar is between 3.8 and 5.6 mmol/L, the target rangefor a controller regulating blood sugar.A patient with type I diabetes needs your help to maintainher blood sugar within an acceptable range (3 mmol/L<glucose<8 mmol/L). She has just eaten a large meal (a disturbance) that you estimate will release glucose accord-ing toD(t)=0.5e−0.05t,wheretis in minutes andD(t)is inmmol/L –…If removal of the pancreas results in a variety of metabolic disturbances that ultimately lead to death, describe the most significant biochemical and physiological changes that would occur due to loss of endocrine function of the pancreas.
