What does frequent infections feel like with type 2 diabetes?

High blood glucose can make it harder for the body to control some infections. You might notice recurring urine burning or urgency, itchy skin folds, boils, thrush, gum soreness, or cuts that become red and tender. Symptoms can return after seeming to improve, or a minor infection may take longer to clear. These features are not specific to diabetes; medicines, immune conditions, skin irritation and other health problems can also contribute. A clinician may review your symptoms, examine the affected area and check glucose with suitable blood tests.

Keep a short record of where each infection occurs, when it starts, what treatment was used and whether it fully cleared. Arrange a medical appointment if infections keep returning or healing is slow. Until you are assessed, follow prescribed treatment instructions, keep skin folds clean and dry, protect open cuts with appropriate dressings, and avoid sharing towels. Do not start leftover antibiotics or stop a prescribed course without medical advice.

Seek urgent medical help for spreading redness, severe pain, rapidly increasing swelling, confusion, faintness, trouble breathing, persistent vomiting or inability to keep fluids down. Fever with a worsening infection also needs prompt assessment, particularly if you have known diabetes or take medicines that affect immunity. A clinician can decide whether glucose testing, a culture or treatment is needed.

Could these infections be related to blood glucose, and should I have testing? Which warning signs mean I should return quickly? Do I need a sample or examination to identify the cause? How should I care for the affected skin while it heals?
