What condition occurs when the body is unable to absorb glucose due to a lack of insulin?

The condition where the body is unable to absorb glucose due to a lack of insulin is diabetes. In diabetes, the pancreas either does not produce enough insulin or the body's cells do not respond effectively to the insulin that is produced. Insulin is crucial for allowing glucose to enter cells, which is essential for providing energy to the body.

When insulin is lacking, glucose remains in the bloodstream rather than being taken up by the cells, leading to high blood sugar levels. This condition is characteristic of diabetes, which can manifest in various forms, most notably Type 1 and Type 2 diabetes. In contrast, hypoglycemia refers to low blood sugar levels, gallstones are solid particles that form in the gallbladder, and hyperglycemia is primarily a term used to describe high blood sugar levels, often a result of diabetes rather than the condition itself.
