Polaciuria means urinating all the time, but in small amounts. The most common causes are bladder problems, enlarged prostate, diabetes, diuretics, caffeine, and alcohol. Treatment ranges from lifestyle changes to surgery. In this article, we discuss the causes, symptoms, and clinical approaches for polaciuria.
Polaciuria is the increase in urinary frequency along with a decrease in volume—that is, urinating more often but in smaller amounts. It can be caused by bladder dysfunction, prostate issues, diabetes, the use of diuretic medications, and the consumption of caffeine and alcohol. Learn what polaciuria is; the following content explains what it is, its possible causes, and how it can be evaluated.
What Is Polaciuria?
Polaciuria is a urinary disorder that causes an urgent need to urinate associated with reduced volume. Individuals with this condition urinate multiple times in small amounts.
What Is the Difference Between Polyuria and Polaciuria?
Both terms refer to changes in the urinary system, but they have different characteristics. See the difference between polyuria and polaciuria:
- Polyuria: excessive urine production, exceeding 2.5–3 liters per day, while normal is between 1 and 2 liters;
- Polaciuria: increased urinary frequency with a small urine volume.
Symptoms of Polaciuria
Discover the symptoms of polaciuria:
- Greater urinary frequency with lower urine volume. This frequency increase may also occur at night, in which case it is called nocturia;
- A feeling of a full bladder even after urinating;
- Dysuria, which is pain when urinating and can be present in urinary tract infections.
Polaciuria also affects mental well-being, as going to the bathroom so frequently disrupts work, study, or leisure activities and may interfere with sleep, causing insecurity.
Main Causes of Polaciuria
Let’s list the 7 main causes of polaciuria:
1. Cystitis
Cystitis is an infection or inflammation of the bladder caused by the bacterium Escherichia coli, which is naturally found in the intestine and is important for digestion, but it can multiply and migrate to the bladder.
In cystitis, in addition to urinating all the time in small quantities, the individual feels pain or a burning sensation when urinating.
2. Overactive Bladder
Overactive bladder is the involuntary contraction of the bladder. This movement creates the feeling of a full bladder even after urinating. In some cases, overactive bladder is associated with urinary incontinence.
This condition is more common in women over 60 years old. In men, it is common among diabetics and obese individuals of any age.
3. Enlarged Prostate
An enlarged prostate, clinically known as benign prostatic hyperplasia, puts pressure on the urethra and bladder. This compression increases urinary frequency. Men with hyperplasia may also have difficulty initiating urination, a weak urine stream, and a feeling of incomplete bladder emptying.
4. Diabetes
Excess sugar in the blood causes a person to urinate more. That’s because when diabetes is high, the body attempts to eliminate the excess sugar via the urine, which draws water with it. This mechanism leads to polyuria—an increase in urine volume.
With more urine, the diabetic individual urinates frequently and becomes dehydrated, needing to drink more water. With increased water intake, urinary frequency also rises—this is polaciuria.
5. Diuretic Medications
Diuretic medications are used to increase urine volume. They are commonly prescribed for high blood pressure, heart failure, and fluid retention.
Since diuretics make the kidneys release more water and salt, the user urinates more often, possibly in small amounts.
6. Radiotherapy
Radiation therapy can affect the nerves of the urinary sphincters—the muscles controlling urine flow. The treatment affects the external sphincter, which the individual controls voluntarily, and the internal sphincter, which controls flow automatically.
7. Excessive Consumption of Caffeine and Alcohol
Coffee is a mild diuretic and therefore increases urine production. This occurs because the beverage stimulates natriuresis, the process of sodium elimination by the kidneys, which draws water and increases urine volume.
Meanwhile, alcohol inhibits the action of ADH (antidiuretic hormone), responsible for regulating how much water is reabsorbed by the kidneys.
How Is Polaciuria Diagnosed?
Diagnosis is made by a urologist, who first evaluates the patient’s medical history to identify if the individual is diabetic or hypertensive, for example.
The physician also performs an abdominal palpation and prostate examination, in addition to ordering urine, blood, and hormone tests, as well as kidney, bladder, and urethral assessments, and imaging exams.
Key Exams for Investigating Polaciuria
The most common exams to detect polaciuria include:
- Urine tests to check for color changes, bacteria, blood, or proteins;
- Tests to assess kidney function;
- Renal and pelvic ultrasound to evaluate the kidneys, bladder, and prostate;
- CT scan or MRI;
- Blood glucose tests;
- Hormonal evaluation;
- Urodynamic studies to measure bladder and urethral function.
Recommended Treatments
The cause determines how to treat polaciuria. Here are some possible protocols:
- Urinary tract infections: antibiotics to control the infection;
- Overactive bladder: exercises to strengthen and medications to support the bladder. Depending on severity, electrical stimulation or surgery may be necessary;
- Enlarged prostate: 5-alpha-reductase inhibitors or alpha blockers, which help reduce prostate size. Surgery can also be prescribed;
- Diabetes: management with medications, healthy eating, and exercise;
- Diuretics: review of usage by the physician.
How to Alleviate Polaciuria Through Healthy Habits
Polaciuria is associated with medical conditions, and habits such as excessive caffeine and alcohol intake also play a role. Therefore, lifestyle changes can help improve or prevent it. Check out what to do:
- Drink water in moderation, adjusting the amount based on your weight and height;
- Reduce or eliminate caffeine;
- Avoid alcoholic beverages;
- Avoid irritating foods to maintain bladder health, such as spicy peppers, artificial sweeteners, citrus fruits, and chocolate;
- Kegel exercises to strengthen the pelvic floor muscles;
- Fiber-rich foods to prevent constipation, as it can put pressure on the bladder;
- Diabetics should manage their condition with medications, a balanced diet, and physical activity.
When to Seek Medical Help?
You should see a doctor as soon as you notice any changes in your urinary flow.
Polaciuria is an increase in urinary frequency that can affect quality of life, but with proper medical guidance, there are therapeutic approaches that may help control the symptoms. If you are experiencing symptoms related to increased urinary frequency, seek a urologist for an individualized evaluation and guidance on the most appropriate treatment.
