- New or worsening urinary symptoms should be discussed with a doctor.
The prostate is a walnut-sized gland that sits just below the bladder and surrounds the urethra, the tube that carries urine out of the body. It plays a role in reproduction by producing part of the seminal fluid. Because of where it sits, changes in the prostate can affect how comfortably you urinate, which is why many men start paying attention to it in midlife.
How the prostate changes with age
Natural growth
For most men, the prostate slowly enlarges from middle age onward. This non-cancerous growth, known as benign prostatic hyperplasia or BPH, is extremely common, affecting around half of men in their 50s and a majority by their 80s.
Pressure on the urethra
As the gland grows, it can press on the urethra, which may affect the flow of urine and how completely the bladder empties.
Hormonal and circulation changes
Shifts in hormones, circulation and bladder muscle tone with age can also influence urinary comfort.
Common signs men notice
| Sign | What it feels like |
|---|---|
| Nighttime urination | Waking up one or more times a night to go |
| Frequency or urgency | Needing to go more often or suddenly |
| Weaker stream | Slower flow or starting and stopping |
| Incomplete emptying | Feeling like the bladder isn't fully empty |
Lifestyle habits that support prostate comfort
Stay physically active and aim for a healthy weight. Eat plenty of vegetables, fruit, whole grains and healthy fats, and limit red and processed meats. Cut back on fluids in the two hours before bed, and moderate caffeine and alcohol, which can irritate the bladder. Don't rush when urinating. Some men also add a daily supplement as part of their wellness routine.

Common questions
Is prostate enlargement normal with age?
Yes. Slow, non-cancerous prostate growth (BPH) is very common as men get older, affecting about half of men in their 50s.
Why do men wake up at night to urinate?
An enlarging prostate, bladder changes and evening fluid intake can all contribute to nighttime urination.
When should men get a prostate check?
Most men should discuss prostate screening with their doctor around age 50, or earlier with a family history.
