Diabetes and Enlarged Prostate: Understanding the Link and Managing Both Conditions

The Link Between Diabetes and Enlarged Prostate

By Dr. David Samadi

The prostate, a small yet vital gland that’s part of man’s reproductive system, plays a crucial role in semen production and sperm transport. While often overlooked, its proximity to the bladder and urethra means that any changes in prostate size can significantly impact urinary function. One of the most common prostate-related conditions in older men is a condition called benign prostatic hyperplasia (BPH), otherwise known as an enlarged prostate. Although the precise causes of BPH remain unclear, certain health conditions—such as diabetes—may increase a man’s risk. Understanding the connection between diabetes and prostate enlargement is essential for men looking to manage their health effectively and mitigate potential complications.

What Is Benign Prostatic Hyperplasia (BPH)?

The prostate, typically the size and even somewhat shape of a walnut, is found sitting below the bladder and surrounds a man’s urethra, which is the tube necessary for carrying urine and semen out of the body. When a man’s prostate enlarges, it will start to press against the urethra, leading to urinary symptoms such as:
  • Difficulty starting urination
  • Weak urine stream
  • Frequent urination, especially at night
  • Incomplete bladder emptying
  • Urine leakage or dribbling
While aging and hormonal changes—such as a decline in testosterone with stable estrogen levels—are considered primary factors in BPH development, emerging research suggests that metabolic conditions like diabetes may also play a role.

How Diabetes May Contribute to BPH

Diabetes, a chronic condition characterized by high blood sugar levels, affects multiple organ systems, including the prostate. Research indicates that men with diabetes often experience more severe BPH symptoms compared to those without the condition. Several potential mechanisms explain this relationship:
  • Insulin Resistance and Prostate Growth: Insulin-like growth factor (IGF), a protein involved in cell growth, has been found in prostatic tissue. Because diabetes disrupts insulin balance, elevated IGF levels may contribute to excessive prostate cell proliferation, leading to BPH.
  • Nerve Damage and Urinary Dysfunction: Diabetes-related nerve damage (neuropathy) can impair bladder function, compounding the urinary difficulties associated with BPH.
  • Chronic Inflammation: Persistent low-grade inflammation, common in diabetes, may exacerbate prostate enlargement and related symptoms.
  • Increased Risk of Urinary Tract Infections (UTIs): Men diagnosed with diabetes, have a higher risk for infections, which can further complicate urinary symptoms linked to BPH.

Managing BPH and Diabetes Simultaneously

For men dealing with both diabetes and BPH, the best approach is to be proactive and to practice good health management. Strategies include:
  • Optimizing Diabetes Control: Keeping blood sugar levels within target ranges through diet, exercise, and medication can reduce inflammation and improve overall urinary health.
  • Medications for BPH: Alpha-blockers (e.g., tamsulosin) can relax prostate and bladder muscles, while 5-alpha reductase inhibitors (e.g., finasteride) help shrink the prostate.
  • Lifestyle Modifications:
    • Reaching and maintaining a healthy weight, as obesity is linked to both conditions
    • Participating most days of the week by being physically activity which can improve insulin sensitivity and reduce urinary symptoms
    • Reducing consumption of excessive amounts of caffeine and alcohol, both which can irritate the bladder
    • Practicing bladder training techniques, such as scheduled voiding
  • Minimally Invasive Treatments: When medication is insufficient, procedures like transurethral microwave therapy (TUMT) or UroLift® can provide relief without major surgery.
  • Surgical Options: In severe cases, transurethral resection of the prostate (TURP) or GreenLight™ laser therapy may be recommended.

Bringing it all together

The interplay between diabetes and BPH highlights why men can take a more holistic approach to their overall health. By addressing diabetes effectively and seeking appropriate care for BPH symptoms, men can play a valuable role in improving their quality of life and reducing the risk of complications. Regular medical check-ups, lifestyle modifications, and early intervention are crucial in managing both conditions successfully.   Dr. David Samadi is the Director of Men’s Health and Urologic Oncology at St. Francis Hospital in Long Island.
