1. Diabetes can affect immune system function, making individuals more susceptible to microbial infections.
2. Hyperglycemia in diabetes creates a favorable environment for certain pathogens to thrive, influencing microbial growth.
3. In diabetic patients, impaired blood circulation and nerve damage increase the risk of infection and delay wound healing.
4. Pathogens like bacteria and fungi can exploit the weakened immune responses in diabetics, leading to increased pathogenicity.
5. Autoimmune disorders such as Type 1 diabetes result from the immune system mistakenly attacking insulin-producing cells in the pancreas.
