Why do women urinate frequently after sex?

Perhaps many women will experience this situation, that is, they will have frequent urination after having sex. This situation may be caused by bladder inflammation, or it may be caused by the virus entering the vagina during sexual intercourse, thus causing some urinary system diseases. People need to pay special attention to this situation, so let’s introduce in detail why women urinate frequently after sex.

After each sexual intercourse, there will be urination irritation symptoms such as urgency and frequency of urination. Sometimes antibiotics are not effective. This may be an infectious disease of the urinary system or a problem with the development of the reproductive organs.

The female urethra is short and wide, and is close to the vagina and anus. The urothelial cells have high adhesion and sensitivity to bacteria, and menstrual blood also provides a good culture medium for bacterial reproduction. Due to the differences in anatomical structures and physiological characteristics, if you do not pay attention to hygiene, it is easy to bring pathogens that parasitize around the urethral opening into the bladder during sexual intercourse, causing cystitis. This is mainly a non-specific infection caused by Escherichia coli in the rectum or vagina. Pathogens from the foreskin and urethra of the sexual partner during sexual intercourse may also be involved in the occurrence of female urinary tract inflammation. If not diagnosed and treated in time, the bacteria in the bladder will flow upstream and enter the renal pelvis and renal parenchyma, causing pyelonephritis, which can be fatal in severe cases. In addition, diseases or abnormalities such as abnormal shape of the external urethral opening (such as the hymen umbrella), spasm of the external urethral sphincter, and fibrosis of the tissue around the distal urethra can also make women more likely to get urinary tract infections after sexual intercourse. Urinary tract infection can be confirmed by clinical examination showing true bacteriuria, and problems with reproductive organ development need to be confirmed by examination by a specialist.

Simply relying on anti-inflammatory drugs to prevent and treat female urinary tract infections is not a panacea. In fact, it has been proven that the use of antibiotics in most similar situations is ineffective, and the problem should be solved fundamentally. Therefore, it is very important to pay attention to sexual hygiene. You should maintain good health at ordinary times, avoid having sex when you are too tired or sick, etc. when the body's resistance is reduced; maintain a stable frequency of sexual intercourse, and avoid excessive sexual intercourse; before and after each sexual intercourse, both parties should thoroughly clean the "key" parts, develop the habit of cleaning with soap, and avoid excessive use of disinfectants to clean the perineum, which may cause bacterial imbalance and decreased resistance, and easy infection; after sexual intercourse, it is best for the woman to urinate once to flush the urethra, which can significantly reduce the incidence of this type of urinary tract inflammation related to sexual intercourse; if you think that the recurrence of urinary tract infection is related to sexual intercourse, you can also take a dose of antibacterial drugs orally immediately after sexual intercourse. Problems with reproductive organ development need to be corrected in a specialized hospital.
