What causes vaginal bleeding the day after sex?

A perfect sex life can make the relationship between husband and wife more harmonious and more intimate. However, due to the physical constitution and sexual life style of many people, some problems always occur after intercourse. Among them, vaginal bleeding on the second day after intercourse is a common problem. Therefore, many people are particularly afraid of it. Let's understand what is going on with vaginal bleeding on the second day after intercourse.

What causes vaginal bleeding the day after sex?

1. The urethra and vagina are close to each other. When the urethra is inflamed, it is easy to be squeezed and injured during sexual intercourse, causing bleeding.

2. The urethral caruncle that grows at the female urethral opening is brittle and soft in texture, and the slightest touch during sexual intercourse can cause bleeding.

3. Cervical erosion: due to the exfoliation of the epithelium around the external os of the cervix, the fragile subcutaneous tissue is exposed to form an erosion surface, which is then impacted by the penis during sexual intercourse and causes bleeding.

4. Due to the infiltration of cancer cells, cervical cancer makes the tissue fragile and often causes contact bleeding during sexual intercourse.

5. Vaginitis: due to the massive shedding of the vaginal epithelium and congestion of the vaginal mucosa, the friction of the penis in the vagina during sexual intercourse causes damage, rupture and bleeding of the vaginal mucosa.

Under normal circumstances, there should be no bleeding during sexual intercourse, so bleeding after sexual intercourse usually has certain reasons. If bleeding during sexual intercourse occurs, do not take it lightly. Go to the hospital for examination as soon as possible to diagnose whether it is due to a gynecological disease, and then receive targeted treatment.

Prevention of Urinary Tract Infections

1. General measures: ① Drink more water, preferably more than 2000 ml per day, and urinate every 2 to 3 hours. ② Patients who have sexual intercourse should urinate in time after sexual intercourse. If necessary, they should consult an obstetrician and gynecologist and choose an appropriate contraceptive method. ③Try to avoid the use of urinary tract instruments. ④ Cranberry juice. Experimental studies have shown that cranberry juice can prevent Escherichia coli from adhering to urothelial cells and help prevent urinary tract infections.

2. Antibiotic prevention: Antibiotic prevention can significantly reduce the chance of recurrence of urinary tract infection in women. For female patients with recurrent urinary tract infections two or more times within six months, or three or more times within one year, antibiotic treatment is recommended (Grade A). Prevention plans include continuous medication and post-coital medication, with a course of 6 to 12 months. These regimens must be used after the original urinary tract infection is cured (urine culture is negative 1 to 2 weeks after stopping the medication), and antibiotics can be selected based on previous drug sensitivity test results and the patient's drug allergy history. Compared with the continuous dosing method, the post-coital medication method is more convenient and more easily accepted by patients who have sexual intercourse. Cephalexin, ciprofloxacin, or nitrofurantoin can be taken within 2 hours after sexual intercourse.

3. Prevention in postmenopausal women: Local application of estrogen ointment in the vagina can restore the local environment of the vagina and reduce the chance of recurrence of urinary tract infection (Grade A).

4. For patients with frequent recurring urinary urges, their urinary system should be carefully examined for anatomical malformations, underlying lesions (such as stones, polycystic kidney disease, medullary sponge kidney, etc.) and overall immune system abnormalities.

The above is an introduction to what causes vaginal bleeding the day after intercourse. After understanding it, we know that there are many reasons for vaginal bleeding the day after intercourse, so if such symptoms occur, they should be relieved in time, and if necessary, go to the hospital for examination and treatment.
