Why does type 2 diabetes cause frequent infections?

Persistently raised glucose can affect how white blood cells move toward germs and clear them. Reduced circulation or nerve changes can make injuries less noticeable and may slow healing, especially in the feet. Skin infections, urinary infections, gum problems, and fungal infections may therefore need close attention.

Frequent Infections is a common presentation of Type 2 Diabetes. Repeated infections do not by themselves identify the cause, because exposure to germs, skin conditions, urinary problems, and immune disorders can also play a part.

Take prescribed treatment for each infection and complete it as directed. Check skin and feet regularly for cuts, redness, swelling, cracks, or discharge; keep wounds clean and protected. Good hand hygiene, dental care, and following your diabetes plan can help reduce avoidable problems. Arrange a review when infections keep returning or a wound is slow to improve.

Seek urgent medical care for fever with worsening illness, spreading redness, severe pain, pus from a wound, a black or pale area of skin, or a foot ulcer. Get prompt advice for burning urination with fever, back pain, vomiting, or visible blood in urine.

Ask whether your glucose management needs review, how to care for a current wound, and whether recurrent infections need tests for another contributing cause.
