I. Diabetes does not only damage peripheral nerves. It damages autonomic nerves. Bowel transit, bladder contraction, detrusor coordination — these are autonomic functions. When a patient walks in with urgency, frequency, constipation, and a long diabetes history, the fallout is already written. You are reading the consequences, not the cause.

II. Sexual dysfunction appears 10 to 15 years earlier in men with diabetes. The younger man with ED you are attributing to anxiety or relationship stress may be showing you the first sign of microvascular and endocrine disease. ED is a systemic signal. Treat it as one.

III. Diabetic cystopathy is a voiding problem, not a storage problem. The bladder does not sense it is full. It overfills. It retains. The incontinence is overflow, not weakness. If you do not have a post-void residual, you do not have a functional diagnosis. And if you are training that patient to hold longer, you are working against the kidneys.

I. "For every complex problem there is an answer that is clear, simple, and wrong." — H.L. Mencken

Kegels are clear. Kegels are simple. For the diabetic bladder that cannot empty, they are wrong.

II. "It is a capital mistake to theorize before one has data." — Arthur Conan Doyle

The three-day bladder diary and post-void residual are not optional extras. They are the data. Without them, you are theorizing.

Does your patient with ED or bladder symptoms have a history of diabetes — and if so, have you checked whether the problem is storage, voiding, or overflow?

PS: Have a patient who would benefit from an easy online bladder diary tracker? We built myflowcheck.com. It's free and available in English, Spanish, and French. Your patient can directly share the results with you after they complete it. HIPAA compliant because the data is only stored on the patient's phone.
