Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar levels. It helps cells in the body absorb glucose, which is the primary source of energy. When we eat, our blood sugar levels rise, prompting the pancreas to release insulin to maintain balance. In people with diabetes, the body either does not produce enough insulin or cannot use it effectively. This can lead to high blood sugar levels, which can cause various health complications. Managing insulin levels is essential for maintaining overall health and preventing long-term issues associated with diabetes.
