Final answer:
Uncontrolled diabetes commonly leads to hyperglycemia, which is a condition of elevated blood sugar levels that can cause various long-term health issues. Management of diabetes may include lifestyle modifications and medications, and improper insulin therapy may result in hypoglycemia.
Step-by-step explanation:
A major problem with uncontrolled diabetes is hyperglycemia, which is characterized by abnormally high blood sugar levels. When the body either does not produce enough insulin or cells do not respond to insulin properly, glucose remains in the bloodstream instead of being absorbed by the cells, leading to hyperglycemia. This condition can cause a range of serious health problems if left untreated, including heart disease, stroke, kidney damage, and nerve damage.
In terms of diabetes treatment, individuals may require a combination of lifestyle changes and medication. For those with type 2 diabetes, insulin therapy can sometimes lead to hypoglycemia if the insulin dose is too high, which is characterized by abnormally low blood sugar levels and can be dangerous if not managed correctly.
