What causes pain in the lower right abdomen?

Right lower abdominal pain can have several possible causes, including the following: 1. **Appendicitis**: Pain in the right lower abdomen is the most common symptom, often accompanied by nausea, vomiting, fever, and mild constipation or diarrhea. If the pain progressively worsens, immediate medical attention is necessary. 2. **Urinary tract infection**: Including pyelonephritis or cystitis, which may cause flank or lower abdominal pain, along with symptoms such as frequent urination, urgency, and painful urination. 3. **Gynecological issues**: In women, ovarian cysts or pelvic inflammatory disease may lead to right lower abdominal pain, sometimes accompanied by menstrual irregularities or pain during intercourse. 4. **Gastrointestinal diseases**: Such as gastrointestinal inflammation, cholecystitis, or gallstones, which may cause pain in the right upper or mid-abdomen, possibly accompanied by jaundice, nausea, or fever. 5. **Muscle strain or intestinal cramps**: These less serious conditions typically cause brief episodes of pain that may be relieved with rest and dietary adjustments. If the pain persists, becomes severe, or is accompanied by other symptoms such as fever, vomiting, blood in the stool, or abnormal urination, prompt medical evaluation and treatment are recommended.
