The typical symptoms of type 2 diabetes are referred to as "three excesses and one deficiency." The three excesses include excessive thirst and dry mouth, increased appetite with frequent hunger, and increased urination. The one deficiency refers to weight loss; these are the more typical symptoms. Some patients might often find out about their elevated blood sugar during routine health checks at work. Others may seek medical advice due to issues like skin itchiness or wounds that heal poorly after injury. Some might mainly experience numbness in their hands and feet, or blurred vision among other symptoms.
