Causes of Frequent Urination in Women

Women that need to urinate more frequently during the day and night, sometimes accompanied by urgency, can have a number of different causes that are not necessarily physical. Causes can include anything from anxiety and stress to excessive fluid intake. It may also be a symptom of cystitis, a warning sign of diabetes, or prompted by overactive bladder syndrome.

Urine is a waste product of our body and is generated by the kidneys thanks to a complex blood filtration system. Excess fluids, toxins, and waste materials are eliminated through the urine.

The amount we urinate in 24 hours depends on numerous factors including daily fluid intake, diet (especially if rich in fruit and vegetables), body and ambient temperature, and blood pressure changes. Physiologically, a healthy individual produces between 500 to 2000ml of urine per day. This equates to urinating around 4-7 times over 24 hours, mainly during the daytime.

There are physical conditions that determine the need to urinate often throughout the day. These conditions sometimes force someone to wake up at night with the need to urinate.

In this article, we will mainly focus on the causes that lead to frequent urination in women during the daytime and at night.

Causes Of Frequent – Urination

Urinary disorders are very common in adults but are most common in women.

Among the main causes that lead to frequent urination in women is cystitis. Due to women having a much shorter urethra than men, and the proximity of the rectum and vagina to the bladder, women are more likely to be exposed to the risk of developing urinary tract infections (or UTI’s).

These infections can result in crampy abdominal pain and a burning sensation when urinating, with increased frequency and the feeling of not having fully emptied the bladder. Poor urinary output can also be associated with urinary tract infections, and the urine may appear cloudy and smelly.

Among the other causes that involve the need to urinate more frequently is anxiety, which represents the second most common cause of frequent urination, especially in young women, and pregnancy. During pregnancy, the uterus increases in size which can compress the bladder, causing an increase in the frequency of urination and potentially urinary incontinence.

Sometimes the urge to urinate is accompanied by an urge to urinate more frequently: this may be due to overactive bladder syndrome.

This condition is due to an overactivity of the detrusor muscle that surrounds the bladder, which contracts regardless of whether the bladder is full or filling. The muscle contracts without the warning of first feeling the need to go to the toilet, which results in urinary incontinence.

Overactive bladder syndrome can be caused by:

  • Obesity
  • Onset of menopause
  • Uro-gynecological interventions
  • A weak pelvic floor
  • Excessive consumption of caffeine and alcohol
  • Smoking
  • Infection
  • Medication
  • Nerve damage

The need to urinate frequently involves considerable physical and psychological discomfort, to the point that people who suffer from it often change their lifestyle habits, avoiding staying away from home for too long, social gatherings, stopping traveling, and sometimes isolating themselves.

Many women with frequent urination problems find using pads or underwear can give them a sense of security to continue with daily activities in the confidence that they are protected should an accident occur.  In these situations,  can provide secure, discreet protection for light bladder leakages.
Causes Of Urinating Often At Night

Some causes of nocturia, or the need to urinate often during the night, are cystitis, or the side effect of some drugs, such as diuretics or drugs used to treat hypertension.

Sometimes the need to urinate often at night can be the first symptom of diabetes, which causes an increase in thirst and urine production, or it can be due to excessive fluid intake in the evening hours, or simply due to a period of anxiety and stress. Other causes might include an overactive bladder or bladder obstruction.

With some simple changes, it is possible to have a very normal, happy, and sociable life – whatever the cause of your urinary frequency is. For advice on getting your urinary frequency under control, we recommend seeking professional advice by contacting your GP or Continence Specialist Nurse.
