Diseases that may be involved in a woman's right lower abdominal pain include:
1. Appendicitis: Overeating, unclean diet, blockage of the appendix lumen, bacterial invasion, etc. can all cause appendicitis, typically manifested as metastatic pain in the lower right abdomen, accompanied by symptoms such as fever, nausea, and vomiting.
2. Enteritis: It may be caused by factors such as excessive consumption of raw and cold foods, unclean diet, etc. Bacteria invade the intestine, causing acute inflammation of the intestinal mucosa. Patients may present with symptoms such as abdominal pain, bloating, nausea, and vomiting.
3. Pelvic inflammatory disease: Decreased immunity, lack of personal hygiene, neglect of sexual hygiene, multiple intrauterine operations, etc. can all trigger pelvic inflammatory disease. Inflammation stimulates congestion and edema of pelvic tissues, leading to pain in the lower right abdomen, accompanied by symptoms such as fever, menstrual abnormalities, and increased vaginal discharge.
4. Cervicitis: Cervical injury and stimulation may trigger cervicitis, with cervical enlargement accompanied by cervical congestion. Inflammation stimulates the abdominal nerves, causing pain, accompanied by increased menstrual flow, fever, and other symptoms.
5. Cystitis: It is generally caused by factors such as unclean sexual activity and bacterial infections. Women have a shorter urethra and are more susceptible to bacterial infections. If the inflammation is severe, bacteria will retrograde and cause pelvic pain in the lower right abdomen.
6. Ectopic pregnancy: If the fertilized egg is implanted in the right fallopian tube, as the fertilized egg gradually grows, it may cause pain in the lower right abdomen. In severe cases, it may manifest as tearing pain on one side of the lower abdomen, accompanied by nausea, defecation, and a feeling of falling.
7. Luteal rupture: Intense exercise, rough sexual intercourse, and other factors can cause the rupture of the corpus luteum, increasing the pressure inside the corpus luteum, resulting in symptoms of lower right abdominal pain, accompanied by nausea, vomiting, dizziness, and other symptoms.
8. Ovarian cyst: If the cyst is large and compresses the lower right abdomen, it can cause pain in the lower right abdomen.
9. Episalpingitis: such as salpingitis and ovarian inflammation on the right side, inflammation can easily cause pelvic adhesions and congestion, leading to pain in the lower right abdomen, which may worsen before and after fatigue, menstruation, and sexual intercourse.
10. Endometriosis: Pain often begins 1-2 days before menstruation, manifested as right lower abdominal pain, dysmenorrhea, and menstrual abnormalities related to menstruation.
11. Ureteral stones: Larger stones can compress, rub, or cause hydronephrosis in the renal pelvis or calyx, leading to dull or dull pain that can radiate along the ureter to the lower right abdomen.
12. Intestinal diseases: such as intestinal tuberculosis, ulcerative colitis, localized enteritis, mesenteric lymphadenitis, etc., usually present with fever first and then abdominal pain. If there is bloating, it may be acute intestinal obstruction. Irritable bowel syndrome may also cause pain in the lower right abdomen, accompanied by symptoms such as abdominal pain, diarrhea, and constipation.
The above are just some possible reasons. When there is pain in the lower right abdomen, it is necessary to seek medical attention in a timely manner for detailed examination, in order to accurately diagnose and take corresponding treatment measures.
