Patient's question:
I want to understand some information about this. My colleague has had this disease, and it seems quite painful. They are also very cautious about their diet. Moreover, the more painful it gets, the less they dare to drink water, thinking it's painful to go to the toilet. I want to understand what causes urinary tract infections. What kind of help is needed: What are the symptoms of a urinary tract infection?Doctor's answer:
Generally, there are several reasons that can lead to frequent urination. The following are the main ones:1. Increased urine output: Under physiological conditions, such as drinking a large amount of water, an increase in fluid intake leads to an increase in urine output, which in turn increases the frequency of urination. In pathological conditions, such as some diabetic patients or patients with diabetes insipidus who drink a lot of water, the urine output and urination frequency are also high.
2. Inflammatory stimulation: Acute cystitis, tuberculous cystitis, urethritis, pyelonephritis, and vulvitis can all cause frequent urination. Under inflammatory stimulation, symptoms such as frequent urination, urgency, and dysuria may occur simultaneously, which are collectively referred to as urinary tract irritation syndrome.
