What are the causes of a lower right abdominal pain?

Updated July 19, 2017

Lower right abdominal pain is defined as pain in the lower area of the abdomen. There are dozens of causes, some which can be easily treated, while others need the immediate attention of a medical professional.


The four most common causes of lower abdominal pain are appendicitis, ectopic pregnancy, pelvic inflammatory disease and kidney stones.

Check with your doctor about any and all symptoms to determine a cause.


This is perhaps one of the most common causes of lower right abdominal pain. It most commonly occurs between the ages of 11 and 39, though it’s been known to occur at any age. Pain usually starts at or around the belly button and moves to the lower right area. Symptoms include a desire to vomit, reduced appetite and fever. Appendicitis can cause a dull to a very sharp pain.

Ectopic pregnancy

This condition occurs outside of the uterus, usually in a Fallopian tube. It can occur with severe pain usually in the lower right (or lower left) abdomen, sometimes presenting with vomiting. This is considered to be a severe medical emergency, so you should seek medical attention immediately.

Pelvic inflammatory disease

Pelvic inflammatory disease is an inflammation of the pelvic region. If the uterus is tilted to the right just slightly, then it can cause a dull, sometimes sharp, lower right abdominal pain. The pain may be accompanied by vaginal discharge, pain during intercourse and fever.

Kidney stones

Kidney stones, or calcium-like deposits in the kidney, usually occur in the kidneys or the ureters (the tubes that drain the kidneys). It can be associated with severe pain and can spread to the back. Seek medical attention, as kidney stones could pose a serious problem for some people.

Other causes

Some lesser common causes include constipation, Crohn’s Disease, Diverticulitis, Endometriosis, pylonephritis, bowel cancer, hernia, colon cancer, gas, gallbladder disease, Irritable Bowel Syndrome, overeating, fatigue, food poisoning, pancreatitis, lead poisoning, cystitis, ovarian cysts, twisted ovary or ovaries, urinary tract infection, or gallstones.
