What are the symptoms of type 2 diabetes?

Type 2 diabetes often develops gradually, and some people notice no clear symptoms at first. Persistently high blood glucose can increase thirst and urination, reduce energy, affect vision, and make cuts or skin infections slower to settle. Genital or urinary infections may recur. A diagnosis cannot be made from symptoms alone; a blood test is needed. Cellulitis, a painful bacterial skin infection, can also require prompt treatment and is not proof of diabetes.

Book a primary-care appointment if symptoms persist, recur, or appear together. Ask about diabetes screening if you have risk factors or have not had recent checks. Record changes in thirst, urination, vision, energy, skin healing, and weight. A clinician can review results and discuss nutrition, activity, education, and medication if diabetes is diagnosed.

Seek urgent help for vomiting, severe abdominal pain, deep or rapid breathing, confusion, fainting, severe dehydration, or rapidly worsening illness. Get prompt assessment for a spreading red, hot, swollen skin area, pus, fever, or severe pain, because these may indicate a significant infection.

Ask which diabetes tests are appropriate, whether your symptoms need same-day review, how to care for a slow-healing wound, and which support could help with food choices, weight, and medicines.
