Why are some patients of diabetes treated by giving injections of insulin?

Insulin, a hormone produced by the pancreas, is essential for regulating blood sugar levels. In cases where the pancreas doesn't produce enough insulin, blood sugar levels can rise, leading to diabetes. Elevated blood sugar can cause damage to organs and blood vessels. To address this, patients with diabetes may receive insulin injections to compensate for the insufficient production of insulin. These injections help control blood sugar levels, preventing complications and enabling effective diabetes management.
