Is incontinence a problem seen in diabetes?

Yes, sometimes. Diabetes, especially with poor glucose control and vascular health, can lead to damage of the autonomic nervous system. If this affects the nerves that control the bladder, this can lead to the body being unable to sense when it needs to urinate. Diabetics with this nerve damage do not go to the bathroom as frequently, leading to increased risk of infection and urinary overflow incontinence.
Very commonly. Diabetes can affect the nerves that involve the feelings to go and the nerves that tell the bladder to squeeze the urine out. Additionally, if your weight is up the increased pressure on the bladder can affect incontinence related to activities like coughing and sneezing.
