Frequent urination is a common symptom of both type 1 and type 2 diabetes.
- When blood glucose levels are high, the kidneys work harder to filter and absorb the extra sugar from the blood. As a result, more urine is generated, resulting in increased frequency of urination.
- In type 1 diabetes, the immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. As a result, the body lacks insulin, a hormone necessary for glucose to enter cells and provide energy.
- In type 2 diabetes, the body becomes resistant to the effects of insulin or doesn't produce enough insulin to maintain normal blood glucose levels.
