What is an enlarged prostate?
THE prostate is a small gland found in the pelvis between the penis and the bladder.
If it becomes enlarged, it can put pressure on the bladder and the urethra - the tube that urine passes through.
The medical term for an enlarged prostate is benign prostatic enlargement (BPE).
It may affect how you go to the toilet. You might notice you have:
- Difficulty starting to pee
- A frequent need to pee, especially at night
- Problems fully emptying your bladder
- A weak flow
- Dribbling urine after you finish
- A sudden urge to urinate
An enlarged prostate is very common in men over the age of 50.
It is not cancerous, and it is not usually serious, though some men require treatment to lessen their symptoms. This might include medication or surgery.
Most sufferers are also encouraged to drink less alcohol and exercise more.
The exact cause isn't known, but doctors believe it is linked to hormonal changes due to age.
Complications are rare, but include urinary tract infections (UTIs), chronic urinary retention (when you cannot empty your bladder fully), and acute urinary retention (the sudden inability to pass any urine).
