Diabetes-related complications or comorbidities
It may be more difficult to control blood sugar as a result of certain diabetes-related complications, which may affect your A1C result. For instance, gum disease, a typical consequence of diabetes, may cause blood sugar levels to rise.
Another problem that is typical in diabetes is chronic kidney disease (CKD). According to research, patients with CKD and diabetes may not be able to use A1C as a reliable indicator of blood sugar levels. Falsely high results for the A1C can be caused by kidney failure and CKD complications such as anemia. You can prevent or treat diabetic problems and other medical concerns by visiting your doctor on a regular basis. Other possible complications include heart disease, nerve damage, eye or vision problems, foot problems, etc.
