Prostate Problems Worse At Night

One of the most embarrassing problems for men as they reach middle age is prostate enlargement. Benign prostatic hyperplasia, or hypertrophy, or BPH refers to the enlargement of the prostate gland causing urinary issues, such as difficulty starting urination, painful urination, incomplete emptying of the urinary bladder, and nocturia or nighttime urination.

But why are prostate problems like BPH, worse at night? Learn more by continuing to read below.

What Is Nocturia?

It’s a good idea to learn what nocturia is all about before we answer the question “Why do prostate problems get worse at night?”. It’s because nocturia is a common nighttime prostate problem. The body produces less urine during sleep which is more concentrated.

Most people can sleep uninterrupted up to 8 hours without needing to wake up at night to urinate. However, you have nocturia you tend to wake up two or more times every night to urinate. Nocturnal polyuria or nocturia is the medical term referring to excessive nighttime urination.

Nocturia can be an indicative sign of various medical conditions, which commonly occur among older adults. Bladder infections, urinary tract infections (UTI), diabetes, anxiety, neurological disorders, and enlargement of the prostate or prostatitis (inflammation of the prostate gland) can cause nocturia.

Prostate Problems Are Worse At Night Because Of A Low Bladder Capacity


Benign prostatic hypertrophy involves obstruction of the urethra or the passageway of urine from the bladder. Because the prostate tissue grows with age, the urethra is partially obstructed which lowers the capacity of the urinary bladder to hold urine. That’s why strict compliance with prescribed medications and prostate health supplements, like Prostagenix, are important.

At nighttime, the urinary bladder among men with BPH experience worse symptoms, like an increased urge to urinate at night. It’s because the urinary bladder can’t hold the expected amount of urine it usually can prior to prostate enlargement.

A study predicts bladder outlet obstruction using non-invasive investigations with symptomatic BPH. There were 122 male respondents with severe urinary tract or BPH symptoms. Transrectal prostate ultrasound, transabdominal ultrasound, and free flow measurement were carried out to measure residual urine, along with a digital rectal examination. Also, all respondents underwent urodynamic flow test.

Here are the findings of the study:

  • The best urinary bladder obstruction predictor is the combination of average urine flow rate and total prostate tissue volume (binary logistic regression model).
  • The peak urine flow rate is an equally important parameter than the average urine flow rate.
  • Higher urinary bladder obstruction is dependent on the peak and average urine flow rates with lower dependence on the transition zone and total prostate volumes.
  • The study suggests that the average and peak flow rates, along with total prostate volume, can be used in predicting urinary bladder obstruction, which is helpful in decision-making when a patient with BPH is qualified for surgical treatment.

Prostate Problems Are Worse At Night Because Of Lifestyle

Whether you have an enlarged prostate or not, your lifestyle can affect urination frequency at bedtime. More so, if you have BPH, your lifestyle can cause nocturia. That’s why lifestyle changes are important if you have been diagnosed with a prostate problem.

Here are the lifestyle changes you need to do to prevent worsening prostate problems:

  • Get enough fluids during the day, but stop drinking beverages or water 2 to 3 hours before bedtime.
  • Avoid drinking beverages containing alcohol and caffeine.
  • Maintaining a healthy weight relieves pressure on the urinary bladder.
  • Take afternoon naps to reduce nocturia.

Prostate Problems Are Worse At Night As Men Advance With Age

Prostate Problems Worse At Night

Men with BPH tend to have progressive urinary signs and symptoms. But remember, having BPH doesn’t necessary mean you’ll also have prostate cancer. From the time you were diagnosed with prostate enlargement, you probably noticed the increasing frequency of urination as years pass by. It’s a good thing that prescription medications are available, and bladder training can help reduce urinary signs and symptoms.

For medications to treat BPH, alpha-blockers can help relax the prostate and urinary bladder muscles so urine can flow more freely. These drugs treat high blood pressure but are also effective in treating prostate gland enlargement. Finasteride is another drug that delays or prevent progression of BPH.

Bladder training to help manage the urinary signs and symptoms of BPH include Kegel’s exercise. You can practice this bladder training by standing at or by sitting on the toilet. Contract your pelvic muscles to help stop and start urine flow. Hold your urine for 5 to 10 seconds, and you can do this for 5 to 15 minutes, thrice to five times daily to help you with urinary bladder control.


Prostate problems get worse at night because of low bladder capacity, prostate gland obstruction due to sleeping positions, lifestyle, and advancing age.

A patient with an enlarged prostate tends to have an overactive bladder because the growing prostate gland obstructs the urethra, causing lower urine flow rate.

That’s why compliance with medications and prostate health supplements, bladder training, and lifestyle changes are important to minimize the signs and symptoms of prostate problems at night.
