What causes vaginal bleeding when straining during bowel movements?

Vaginal bleeding generally comes from the vulva, vagina, cervix and endometrium. Vaginal bleeding is considered to be due to gynecological inflammation, especially cervical erosion, cervicitis or endometritis, and vaginitis is more likely. But why does vaginal bleeding occur sometimes when straining to defecate? What is the reason? Is it serious? Let us find out through the following.

1. Constipation

Among the factors causing anal diseases, constipation is the biggest culprit. Long-term retention of stool in the rectum can not only induce rectal cancer, but the accumulation of feces also affects blood circulation. When patients forcefully expel dry feces, the anus will inevitably be under greater pressure, resulting in a series of pathological changes such as cracks and swelling. In addition, if anal fissure patients do not cure constipation during treatment, and constipation worsens in the future, it may induce anal fissure again, resulting in repeated recurrence of anal fissure.

2. Bad bowel habits

When going to the toilet, a large number of people like to squat and read books or newspapers, which causes prolonged squatting and defecation time, easily causing blood stasis in the anus and rectum and inducing diseases. Smoking while going to the toilet can buffer the brain's defecation reflex and can easily cause constipation. Some people use too much force during defecation. Regardless of whether the feeling of defecation is strong or not, they blindly and continuously struggle hard. This only adds unnecessary burden and local congestion to the rectum, anus and pelvic floor muscles, leading to the occurrence and development of anal fissures.

3. Infection factors

Some anorectal diseases such as acute and chronic anal sinusitis, anal papillitis, internal hemorrhoids and anorectal polyps are the main causes of infection. The infected pathogenic bacteria enter the anal glands through the gland opening, form abscesses in the subcutaneous tissue of the anal canal, and then form ulcers after rupture. Small superficial thrombi may cause thrombophlebitis due to infection and may also lead to anal fissures.

4. Other factors

In addition to the above three factors, people's unreasonable eating habits, trauma, chronic diseases and human physiological factors may induce anal fissures.

After reading the above, do you know what causes vaginal bleeding when straining to defecate? There are many reasons for vaginal bleeding. We must pay more attention to our daily diet. It should be soft, with little residue, easy to digest, and less irritating. Avoid tobacco, alcohol, and spicy foods. If the condition is more serious, seek medical attention immediately.
