sleep deprivation , bacterial infection, and blood loss, are stress conditons which leads to increase in stress harmones which will decrease the effect of insulin and increase blood glucose
this patient is hypoglycemia so no link with above all and i donot think there is a link of hypoglycemia with obesity so the right ans is D. Participating in a 5k race

This is why D is the right answer...

Exercise is an important cause of hypoglycemia in diabetics. Exercise is generally associated with lowering of blood sugar both in diabetic and non-diabetic individuals. Exercise increases glucose uptake by muscle cells through two main mechanisms (1) Sensitization of muscle cells to the action of insulin, and (2) increased insulin-independent glucose uptake into the exercising muscles. In normal individuals, a drop in blood glucose will stop insulin release from beta cells, which prevents a further drop in blood glucose However, diabetics do not have this feedback mechanism because they are treated with exogenous insulin or sulfonylurea agents (insulin secretogogue) which causes circulating insulin levels to remain elevated despite low blood glucose levels.
