Causes of abnormally frequent urination that are not due to Pollakiuria are as follows:
- Abnormalities of the urinary bladder on voiding
- Abnormalities of the nervous system which controls the release of urine are usually present since birth or are the result of damage or an injury to the parts of the spine and spine cord that control urination. Children suffering from this syndrome experience dribbling urine or a weak flow urine stream. Some urine will also remain in the urinary bladder over the limit. A physical examination, the urination record and additional diagnostic test can help screen out diseases that are not related to this condition.
- Abnormalities in the urinary bladder that are not related to the nervous system, a functional disturbance of the normal voiding cycle, may be caused by the muscles of the urinary bladder or a lack of inhibitory cerebral control over bladder contraction.
- Infection
- Enterobius infection
- Urinary tract infection
- Infection or wounds in the vicinity of the sexual organ in girls or urethra or urethral opening, the distal part of urinary tract in boys
- Diseases that contribute to an unusually large volume of urine include diabetes, diabetes insipidus, or the accumulation of stones in the kidney tissue or the urinary tract (the possibility of stones in the urinary tract in children are rare and far lower when compared to adults). In case there is any reliable indication of the presence of this condition, a urine test and a blood test are required.
- Intake of drugs or substances that stimulate frequent urination including diuretics or some groups of bronchodilators, some types of anti-allergic drugs, and some types of psychotropic drugs.
- Other Causes
- Overly frequent and overly high consumption of water
- Intake of food or drinks that contains caffeine such as tea, carbonated drinks, cocoa and chocolate, and in some cases, the consumption of drinks that contain acid or oxalate including black tea, iced tea, orange juice, apple juice, grape juice, grapefruit juice , or tomato juice
- Constipation
- Sexual assault in children which causes wounds, irritation, or infection of the sexual organs and other nearby organs, and also has a psychological impact on the children
To confirm the diagnosis of Pollakiuria, it is important to screen out the above mentioned conditions. However, in certain cases, it is very difficult to isolate some conditions which are believed to trigger Pollakiuria. These include:
- Viral infection of the urinary tract
- Irritation or inflammation of urethra and urethral opening, caused by chemical substances
- Abnormally high amounts of calcium, oxalate or acid found in the urine
- The urinary bladder being over-sensitive to cool temperatures
- Children having mental stress as a result of the environment they live in or unknown internal trigger from their own minds
