How does diabetes affect my immune system?

Diabetes can weaken the immune system, making individuals more susceptible to infections. High blood sugar levels can impair the function of white blood cells, which are essential for fighting off infections. This means that even minor cuts or wounds can take longer to heal. It's important for people with diabetes to monitor their blood sugar levels, maintain good hygiene, and get regular vaccinations, such as for the flu. If you notice any signs of infection, such as redness, swelling, or fever, consult your GP promptly to avoid complications.
