Patient's question:
My kidneys have only been examined with ultrasound, but the results showed no abnormalities. I just feel like I need to use the restroom whenever I drink a little water, so I suspect there might be something wrong with my kidneys. As for the lump on my head, I don't know when it suddenly appeared—it doesn't hurt or itch, so I just ignored it! I never expected that this missed period would lead to so many problems. I still haven't gotten my period yet. Am I going to die soon?Doctor's answer:
Hello:Frequency of urination refers to an increase in the number of urination episodes. In normal adults, the average number of daytime urinations is 4 to 6 times, and 0 to 2 times at night; infants urinate 20 to 30 times during the day and night. If the number of urination episodes increases significantly and exceeds the above range, it is considered frequent urination. There are many causes of frequent urination, which can be summarized into the following categories:
(1) Increased urine volume: When urine volume increases, the number of urination episodes also increases accordingly. In physiological conditions, such as drinking a large amount of water, eating watermelon, or drinking beer, due to increased fluid intake, the kidneys regulate and filter the fluid, leading to an increase in urine volume and urination frequency, resulting in frequent urination. In pathological conditions, such as some diabetic patients or patients with diabetes insipidus who drink a lot of water and produce a lot of urine, the number of urination episodes also increases. However, there is no discomfort during urination.
(2) Inflammatory stimulation: When there is inflammation in the bladder, the nerve sensory threshold decreases, and the urinary center is in an excited state, leading to frequent urination and a reduced urine volume (less than 300 to 500 milliliters per episode in adults). Therefore, frequent urination is an important symptom of cystitis, especially in acute cystitis and tuberculous cystitis. Other conditions, such as prostatitis, urethritis, pyelonephritis, chronic balanoposthitis in children, and vulvitis, can also cause frequent urination. Under inflammatory stimulation, frequent urination, urinary urgency, and urinary pain often occur simultaneously, known as urinary irritation syndrome, commonly referred to as the "three urinary symptoms."
(3) Non-inflammatory stimulation: Such as urinary stones or foreign bodies, which typically manifest primarily as frequent urination.
(4) Reduced bladder capacity: Such as bladder occupying lesions or the enlarged uterus compressing during pregnancy
