Enlarged prostate
The prostate is a gland that produces some of the fluid that carries sperm during ejaculation. The prostate gland surrounds the urethra, the tube through which urine passes out of the body.
An enlarged prostate means the gland has grown bigger. Prostate enlargement happens to almost all men as they get older.
An enlarged prostate is often called benign prostatic hyperplasia (BPH). It is not cancer, and it does not raise your risk for prostate cancer.
Enlarged prostate - Animation
Not every man will have to deal with age-related issues like balding or weight gain. Whether you have these problems really depends on your health, and luck. But one problem just about every man will have to face, if he lives long enough, is an enlarged prostate. Let's talk about an enlarged prostate, also known as benign prostatic hyperplasia, or BPH. The prostate gland is part of your reproductive system, and its job is to add fluid to the sperm before ejaculation. The prostate is pretty small when you're young, but as you get older it grows and grows. Keep in mind, this growth isn't cancerous. But by design, the prostate is wrapped around the urethra, the tube that carries urine from your bladder out of your body. So as the prostate grows, it can begin to squeeze or pinch the urethra which often can make it harder for men with an enlarged prostate to urinate. If you have an enlarged prostate, the first notice that you're having trouble urinating. Instead of having a strong even flow, the urine only dribbles out like a leaky faucet; drip, drip, dribble, drip. Because you're not emptying your bladder fully each time, you keep feeling the urge to use the bathroom, even in the middle of the night. To check your prostate, your doctor or urologist will check your prostate gland by inserting a lubricated, gloved finger and feeling for any growth. Other tests may check your urine flow, and how much urine is left in your bladder after you go, as well as look for signs of an infection or prostate cancer. How is an enlarged prostate treated? Treatment often depends on how you feel. If you're not having any symptoms, your doctor may suggest just watching it, that's called watchful waiting. If you've got bothersome symptoms, medications can reduce the size of the prostate gland, and relax your bladder and prostate so you don't constantly feel the urge to go. For more serious symptoms, surgery can remove the extra prostate tissue. To help relieve the symptoms of an enlarged prostate, watch how much fluid you drink, especially before bedtime, or before going out. Minimize alcohol and caffeine, as well as over-the-counter decongestants and antihistamines. They can make your symptoms worse. Double voiding can help. After you've emptied your bladder, wait a moment and try to go again without straining or pushing. Some people take herbs like saw palmetto for an enlarged prostate. Although there's some evidence that these herbs can relieve BPH symptoms, many studies haven't found a benefit. Talk to your doctor before taking any herbal remedy, because they can cause side effects. Prostate enlargement isn't usually serious, but it can have a serious impact on your way of life, especially when you're always going to the bathroom. Remember that BPH is treatable. Work with your doctor to find the treatment that works best for you. If you've been caring for your symptoms for 2 months and not finding any relief, or you're having more serious symptoms like you're not urinating at all, or you have a fever or pain in your back or abdomen, call your doctor as soon as possible.
Causes
The actual cause of prostate enlargement is unknown. Factors linked to aging and changes in the cells of the testicles may have a role in the growth of the gland, as well as testosterone levels. Men who have had their testicles removed at a young age (for example, as a result of testicular cancer) do not develop BPH.
Also, if the testicles are removed after a man develops BPH, the prostate begins to shrink in size. However, this is not a standard treatment for an enlarged prostate.
Male reproductive anatomy
The male reproductive structures include the penis, the scrotum, the testicles (testes), the epididymis, the seminal vesicles, and the prostate.
Some facts about prostate enlargement:
- The likelihood of developing an enlarged prostate increases with age.
- BPH is so common that it has been said all men will have an enlarged prostate if they live long enough.
- A small amount of prostate enlargement is present in many men over age 40. More than 90% of men over age 80 have the condition.
- No risk factors have been identified, other than having normally-functioning testicles.
Symptoms
Less than half of all men with BPH have symptoms of the disease. Symptoms may include:
- Dribbling at the end of urinating
- Inability to urinate (urinary retention)
- Incomplete emptying of your bladder
- Incontinence

You may be asked to fill out a form to rate how bad your symptoms are and how much they affect your daily life. Your provider can use this score to judge if your condition is getting worse over time.
Treatment
The treatment you choose will be based on how bad your symptoms are and how much they bother you. Your provider will also take into account other medical problems you may have.
Treatment options include "watchful waiting," lifestyle changes, medicines, or surgery.
If you are over 60, you are more likely to have symptoms. But many men with an enlarged prostate have only minor symptoms. Self-care steps are often enough to make you feel better.
If you have BPH, you should have a yearly assessment to monitor your symptoms and see if you need changes in treatment.
SELF-CARE
For mild symptoms:
- Urinate when you first get the urge. Also, go to the bathroom on a timed schedule, even if you don't feel a need to urinate.
- Avoid alcohol and caffeine, especially after dinner.
- Do not drink a lot of fluid all at once. Spread out fluids during the day. Avoid drinking fluids within 2 hours of bedtime.
- Try not to take over-the-counter cold and sinus medicines that contain decongestants or antihistamines. These medicines can increase BPH symptoms.
- Keep warm and exercise regularly. Cold weather and lack of physical activity may worsen symptoms.
- Reduce stress. Nervousness and tension can lead to more frequent urination.
MEDICINES
Alpha-1 blockers are a class of medicines, some of which have been used to treat high blood pressure. These medicines relax the muscles of the bladder neck and prostate. This allows easier urination. Most people who take alpha-1 blockers notice improvement in their symptoms, usually within 3 to 7 days after starting the medicine.
Finasteride and dutasteride lower levels of hormones produced by the prostate. These medicines also reduce the size of the gland, increase urine flow rate, and decrease symptoms of BPH. You may need to take these medicines for 3 to 6 months before you notice symptoms getting better. Possible side effects include decreased sex drive and impotence.
