Frequent urination despite drinking little water is not necessarily due to kidney failure

Urinating many times a day, even when not drinking much water, is a fairly common symptom. Many cases associate this condition with chronic kidney failure, leading to self-treatment based on word-of-mouth methods or delay in going to the doctor, missing the real cause, causing the disease to progress silently.

According to MSc. Tang Chi Quyen, Kidney Surgery – Urology – Andrology Unit, An Binh Hospital, common causes of frequent urination are mainly related to the bladder or lower urinary tract, instead of the kidneys.

Among them, overactive bladder is a common cause. This condition causes the bladder to contract excessively, causing a sudden urge to urinate, difficulty holding in, and frequent urination throughout the day and night even though the amount of urine each time is small. Because it is not clearly related to infection or stones, the disease is easily overlooked.

Besides, in men, especially after the age of 40, benign prostatic hyperplasia is common. The enlarged prostate compresses the urethra, obstructing the flow of urine, forcing the bladder to contract more. Patients therefore urinate frequently, urinate at night, have a weak stream of urine, and feel incomplete urination.

In addition, urinary tract infection is also a common cause. Initially, the patient may only have painful urination, frequent urination or discomfort in the lower abdomen. If left untreated, the bacteria can spread to the kidneys causing acute pyelonephritis, affecting kidney function. In people who are older or have underlying diseases such as diabetes, hypertension, or prolonged infections, there is also a risk of leading to sepsis – a life-threatening emergency if not treated promptly.

Doctor Quyen recommends that when frequent urination persists, especially with painful urination, nocturia, incomplete urination or fatigue, the patient should see a doctor early. Tests such as urine, blood sugar and urinary system ultrasound help determine the cause and treatment.

Not all cases of frequent urination are dangerous, but correctly diagnosing the cause is key. Early detection and timely treatment help improve symptoms, while preventing complications and preserving kidney function.
