What are the causes of frequent urination and incomplete urination?

Frequent urination means that the number of urination increases. In life, not only some male friends will have frequent urination, but women will also have frequent urination and urgency. However, because this disease is a private issue, many people are too shy to go to the hospital for examination and treatment. They often give up treatment, which greatly affects people's health. Today, I will introduce to you the specific reasons why women have frequent urination and urgency!

Frequent urination refers to an increase in the number of urinations. A normal adult urinates an average of 4 to 6 times during the day and 0 to 2 times at night after going to bed; infants urinate 20 to 30 times during the day and night. If the number of urinations increases significantly and exceeds the above range, it is frequent urination. There are many reasons for frequent urination, which can be summarized as follows:

(1) Increased urine volume: When urine volume increases, the frequency of urination will also increase accordingly. Under physiological conditions, such as drinking a lot of water, eating watermelon, and drinking beer, due to the increase in water intake, the urine volume increases through the regulation and filtering function of the kidneys, and the frequency of urination also increases, resulting in frequent urination. Under pathological conditions, such as some patients with diabetes and diabetes insipidus who drink a lot of water, have a large urine volume, and urinate frequently. However, they do not feel any discomfort when urinating.

(2) Inflammatory stimulation: When there is inflammation in the bladder, the nerve receptor threshold is lowered, the urinary center is in an excited state, resulting in frequent urination and reduced urine volume (<300-500 ml/time for adults). Therefore, frequent urination is an important symptom of cystitis, especially acute cystitis and tuberculous cystitis. Other diseases such as prostatitis, urethritis, pyelonephritis, chronic pediatric glans dermatitis, and vulvitis can also cause frequent urination. Under the stimulation of inflammation, frequent urination, urgency, and pain often occur at the same time, which is called urinary tract irritation sign, commonly known as "tri-urination sign".

(3) Non-inflammatory irritation: such as urinary tract stones and foreign bodies, usually with frequent urination as the main manifestation.

(5) Psychoneural urinary frequency: Frequent urination occurs only during the day or before going to sleep at night, often due to mental tension or hysteria. It may also be accompanied by urinary urgency and pain.

Frequent urination in women is also a very common topic. The editor reminds the majority of female friends that the reason for frequent urination may be due to some diseases, so this requires us to pay more attention to observation in normal times. If it is a disease, you need to go to the hospital for diagnosis immediately. Female friends need to pay more attention to care in normal times.
