Pain in the lower right side of the belly can be confusing because so many organs sit close together there. For women, that area holds part of the intestines, the appendix, the right ovary, and the fallopian tube, so the cause can range from trapped gas to a medical emergency. If you are wondering what causes lower right abdominal pain in women, the answer depends on how the pain started, how severe it is, and what other symptoms come with it.
Mild cramps that come and go are often harmless, but sudden, severe, or worsening pain should never be ignored. If you are searching for an emergency room near me because the pain is sharp or comes with fever or vomiting, East Houston Medical Center is open 24/7 with on-site imaging and labs.
Common Causes Of Lower Right Abdominal Pain In Women
1. Appendicitis
Appendicitis is one of the most important causes to rule out. Pain often starts around the belly button and moves to the lower right side over several hours. It may come with fever, nausea, vomiting, and loss of appetite. A swollen appendix can burst, so appendicitis needs emergency care right away.
2. Ovarian Cysts
Most ovarian cysts are harmless and go away on their own. Larger cysts can cause a dull ache or pressure, while a cyst that bursts can cause sudden, sharp pain that needs prompt medical care and evaluation.
3. Ovarian Torsion
Ovarian torsion happens when the ovary twists and cuts off its own blood supply. It causes sudden, severe pelvic pain, often with nausea and vomiting, and needs emergency surgery right away to save the ovary.
4. Ectopic Pregnancy
An ectopic pregnancy grows outside the uterus, usually in a fallopian tube. It may cause one-sided pain, vaginal bleeding, dizziness, or shoulder pain. A ruptured ectopic pregnancy is life-threatening, so any woman who could be pregnant and has this pain should seek care immediately.
5. Menstrual Cramps And Mittelschmerz
Period cramps can cause lower abdominal pain on one or both sides. Some women also feel a brief, one-sided pain mid-cycle when an egg is released, called mittelschmerz, which usually fades within a day or two.
6. Endometriosis
Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus. It can cause chronic pelvic pain, painful periods, pain during sex, and in some cases trouble getting pregnant.
7. Pelvic Inflammatory Disease (PID)
PID is an infection of the reproductive organs, often caused by sexually transmitted infections. It may cause lower abdominal pain, fever, unusual discharge, and pain during sex, so early treatment is important.
8. Kidney Stones Or Kidney Infection
Kidney stones cause intense pain that starts in the back or side and moves toward the lower abdomen and groin. A kidney infection may bring fever, chills, nausea, and painful urination, and needs prompt treatment.
9. Urinary Tract Infection (UTI)
A UTI can cause pelvic pressure, burning when you urinate, and frequent urges to go. Untreated UTIs can spread to the kidneys, so see a doctor if symptoms last or you develop a fever or back pain.
10. Digestive Problems
Gas, constipation, irritable bowel syndrome, inflammatory bowel disease, and hernias can all cause pain in the lower right abdomen, often with bloating, cramping, nausea, or changes in your bowel habits.
Symptoms That Can Help Point To The Cause
- Fever and vomiting: may suggest appendicitis, infection, or PID.
- Missed period or vaginal bleeding: raises concern for ectopic pregnancy.
- Pain with urination: points toward a UTI or kidney stone.
- Pain tied to your cycle: may be linked to ovulation, cysts, or endometriosis.
- Bloating that improves after a bowel movement: often digestive.
How Doctors Diagnose The Cause
In the ER, doctors will ask when the pain started, where it is, and whether it has moved. They will examine your abdomen and may order:
- Pregnancy test: for all women of childbearing age.
- Blood and urine tests: to check for infection, bleeding, or kidney problems.
- Ultrasound: to look at the ovaries, uterus, and appendix.
- CT scan: to check for appendicitis, kidney stones, and bowel problems.

When To Go To The ER For Lower Right Abdominal Pain
Go to the nearest emergency room or call 911 if you have:
- Sudden, severe pain that makes it hard to stand or walk.
- Pain with fever, vomiting, or a hard, tender belly.
- Pain during pregnancy or with a positive pregnancy test.
- Heavy vaginal bleeding, fainting, or dizziness.
- Blood in your vomit, urine, or stool.
- Pain that keeps getting worse over several hours.
Many women delay care because they are worried about long waits. Checking emergency room wait times before you leave home can help, but with possible appendicitis or ectopic pregnancy, every minute counts, so do not wait.
