Why do women urinate frequently and painfully?

Some female friends may have had this experience, that is, frequent urination and painful urination. For humans, one of the vital signs of life is metabolism, and urination, which is what we call peeing, is a very normal physiological behavior. However, if a woman has frequent and painful urination, it is not a normal physiological phenomenon. So what is going on with them? The following article will explain it to you.

Urinary frequency refers to increased frequency of urination. A normal adult urinates an average of 4 to 6 times a day during the day and 0 to 2 times at night after going to bed; an infant urinates 20 to 30 times during the day and night. If the frequency of urination increases significantly and exceeds the above range, it is frequent urination. There are many reasons for this, such as 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, they drink a lot of water, urinate a lot, and urinate frequently, but they do not feel any discomfort when urinating. Inflammatory stimulation: When there is inflammation in the bladder, the urinary center is in an excited state, resulting in frequent urination and reduced urine volume. Under the stimulation of inflammation, frequent urination and painful urination often occur at the same time, which is called urinary tract irritation syndrome, commonly known as "triuria". Non-inflammatory irritation: such as urinary stones and foreign bodies, usually with frequent urination as the main manifestation. Reduced bladder capacity: such as bladder space-occupying lesions, compression from the enlarged uterus during pregnancy, tuberculous bladder contracture, or large bladder stones. Psychoneural urinary frequency: Frequent urination only occurs during the day or before falling asleep at night, and is often caused by mental stress or occurs in patients with hysteria. Female urinary pain refers to the pain that women experience when urinating, which is a symptom caused by infection and other reproductive tract diseases. It is a normal physiological process for humans to excrete excess water. It should not be painful for women to excrete urine through the urethra. So, why do women experience pain when urinating? First of all, the female urethra and vagina are adjacent to each other, and bacteria can easily invade the vagina, especially after sexual intercourse. This is why "honeymoon cystitis" occurs. Secondly, the female vagina is close to the intestines and anus, and many large intestinal bacteria can enter the vagina, causing urinary tract infection and leading to painful urination. Third, although the surface of the female urinary tract is covered with a layer of mucus like a protective film, under normal circumstances, the vaginal mucosa will breed a kind of lactobacillus, making the vagina acidic and inhibiting bacterial invasion. However, when these natural defense functions are congenitally deficient or acquiredly changed, they can easily cause vaginal or urinary tract infections. Fourth, allergies to soap, toilet paper, lubricants, vaginal cleansers, contraceptive sponges or foams can also cause urinary pain. Experts point out that endocervicitis, nonspecific vaginitis, candidal vaginitis, uterine fibroids, ovarian tumors, urinary stones, cancer that requires chemotherapy or pelvic radiation therapy can all cause urinary pain.

Generally speaking, summer is a time when women are more likely to experience symptoms of frequent and painful urination, and it can be caused by a variety of diseases. This is because the temperature is high in summer and people sweat a lot, so various disease bacteria can easily invade the urethra, causing congestion and edema of the female urethra, making it easy for women to urinate frequently, urgently, and painfully. Therefore, female friends should pay special attention to physiological hygiene in summer, prevent reproductive diseases and avoid urinary pain.
