What Causes Frequent Urination? Common Reasons, Symptoms, and When to See a Doctor
Written By
Blen Shumiye, MD
Frequent urination means needing to urinate more often than usual, sometimes urgently or in large amounts. It can be a temporary inconvenience caused by something as simple as increased fluid intake, or it can be a sign of an underlying medical condition that requires treatment.
This guide explains the most common causes of frequent urination, how to tell when it’s serious, and what doctors do to diagnose the problem.
What Counts as Frequent Urination?
Most adults urinate six to eight times per day. Going more often may be considered frequent urination, especially when it:
-
Interrupts daily activities
-
Disrupts sleep (nocturia)
-
Comes with urgency or discomfort
-
Occurs without obvious increased fluid intake
If the need to urinate frequently persists for more than a few days, it may be time to investigate the cause.
Common Causes of Frequent Urination
Many conditions can increase urination frequency. Some are harmless; others require treatment.
1. Urinary Tract Infection (UTI)
A UTI is one of the most common causes of frequent urination, especially in women.
Symptoms include:
-
Burning or pain when urinating
-
Cloudy or strong-smelling urine
-
Lower abdominal pain
-
Urgency even with little urine produced
UTIs require prompt treatment to prevent complications.
Read on in our UTI testing guide to better understand symptoms and treatment.
2. Diabetes (Type 1 or Type 2)
High blood sugar pulls fluid into the urine, leading to:
-
Frequent urination
-
Excessive thirst
-
Fatigue
Frequent urination is often one of the first signs of undiagnosed diabetes.
3. Overactive Bladder (OAB)
OAB causes sudden, strong urges to urinate even when the bladder is not full.
Symptoms include:
-
Urgency
-
Frequent urination
-
In some cases, urine leakage
4. Enlarged Prostate (Men)
For men, an enlarged prostate (BPH) is a common cause.
It may cause:
-
Weak urine stream
-
Difficulty starting urination
-
Incomplete bladder emptying
-
Frequent nighttime urination
5. Pregnancy (Women)
Hormonal changes and pressure on the bladder cause increased urination early and late in pregnancy.
6. Diuretics and Other Medications
Medications that increase urine production include:
-
Diuretics (for blood pressure or swelling)
-
Certain blood pressure medications
-
Some mental health medications
7. Excess Fluid or Caffeine Intake
Caffeine, alcohol, and high fluid intake increase urine production.

8. Bladder or Kidney Stones
Stones irritate the bladder or block urinary flow, leading to:
-
Frequent urination
-
Pain
-
Blood in the urine
9. Vaginal or Prostate Infections
Inflammation near the urinary tract can irritate the bladder.
10. Interstitial Cystitis (Painful Bladder Syndrome)
A chronic condition characterized by:
-
Frequent urination
-
Pelvic pain
-
Pressure in the bladder
11. Anxiety or Stress
Stress hormones can increase the urge to urinate.
Less Common Causes

Less common but serious causes include:
-
Neurological disorders (MS, Parkinson’s, stroke)
-
Bladder cancer
-
Pelvic organ prolapse (women)
These conditions often come with additional symptoms.
Symptoms That May Accompany Frequent Urination
Depending on the cause, you may also notice:
-
Burning or discomfort
-
Fever or chills
-
Intense urgency
-
Blood in the urine
-
Pain in the back or side
-
Pelvic discomfort
-
Weak stream (men)
-
Unintentional weight loss
These signs help identify whether the cause is infection, diabetes, stones, or another issue.
When to See a Doctor
Seek medical attention if you experience:
-
Painful urination
-
Fever or chills
-
Blood in the urine
-
Persistent urgency or frequency lasting more than two days
-
Severe back or side pain
-
Difficulty emptying the bladder
-
Excessive thirst along with frequent urination
These symptoms may indicate infection, diabetes, or kidney problems.
How Doctors Diagnose Frequent Urination

Your provider may perform:
-
Urinalysis
-
Urine culture
-
Blood sugar tests
-
Physical exam (pelvic exam for women, prostate exam for men)
-
Bladder ultrasound
-
Kidney imaging if needed
These tests help identify infection, stones, diabetes, OAB, or structural changes.

For diabetes: Blood sugar control through diet, medication, and lifestyle changes.
-
For overactive bladder: Pelvic floor therapy, bladder training, and medications.
-
For enlarged prostate: Medications, minimally invasive procedures, or surgery.
-
For stones: Hydration, pain control, or removal procedures.
-
For anxiety-related symptoms: Stress management and therapy.
Lifestyle Tips to Reduce Frequent Urination
You can support bladder health by:

Reducing caffeine and alcohol
-
Avoiding fluids right before bed
-
Maintaining a healthy weight
-
Practicing pelvic floor exercises
-
Limiting carbonated and spicy foods

Managing blood sugar and blood pressure
The Bottom Line
Frequent urination has many possible causes ranging from mild to serious. Most are treatable once the underlying cause is identified.
If frequent urination affects your daily life or comes with pain, blood in the urine, fever, or persistent urgency, get evaluated by a healthcare provider.
Early diagnosis ensures proper treatment and helps protect your bladder, kidneys, and overall health.
