With increased urination, those affected not only feel the urge to urinate more frequently, but usually also more suddenly and strongly. In some cases, this increased urge to urinate can be accompanied by urinary incontinence, i.e. an unwanted urinary outflow.
Further information
Causes of frequent urination are:
- Prostate problems – In men, an enlarged or inflamed prostate often leads to frequent urination.
- Diabetes – When excess glucose from the blood is released into the urine, it removes water from the body tissue. This is followed by urination, thirst and dehydration.
- Side effect of a drug – diuretics can increase the frequency of urination.
- Urinary tract infections – symptoms can include pain when urinating, foul-smelling urine, fever and pelvic pain.
- Age-related changes – Weakening the muscles can reduce the capacity of the bladder and the ability to adhere.
- Bladder problems – If bladder problems occur, smokers in particular should consult a doctor. Frequent urination can be an early symptom of bladder cancer.
- Bladder stones or cystitis can also lead to frequent urination. However, they often also cause pain in the pelvic area and when urinating.
- Heart failure – A weak heart cannot pump the blood sufficiently through the body. Water accumulations form in the tissues – so-called edema. The excess fluid must be excreted by increased kidney activity. This results in large amounts of urine being produced.
- Kidney disease – If kidney activity is reduced, it can reduce the kidney’s ability to concentrate urine. The amount of urine produced is increasing.
