Type 2 diabetes is a metabolic condition where the body struggles to keep blood sugar in a healthy range. It often starts with insulin resistance, meaning your cells do not use insulin efficiently even when your body is making enough. Over time, the pancreas may have a harder time keeping up, and glucose levels can stay elevated more often.
Some people notice symptoms early. Others find out through lab work, such as A1C, fasting glucose, or insulin markers. Because metabolism affects many systems, it can overlap with weight changes, inflammation, blood pressure concerns, and low energy.
