Your abdomen is divided into four quadrants by two imaginary lines. One line runs vertically, cutting the abdomen into halves. The other line travels horizontally from the bottom of the ribs to the top of the pubic area. This post will focus on the Right Lower Quadrant (RLQ).After reading this article, you will know the organs in that region and the possible reasons you are experiencing pain in that area.

Common Causes of Pain in Right Lower Abdomen


Appendicitis occurs when the appendix becomes inflamed. Appendicitis is one of the most common causes of pain in the lower right abdomen.

It causes pain to develop in the center of the abdomen. The pain becomes more severe as it spreads to the lower right abdomen.

With appendicitis, the typical treatment modality is surgery (appendectomy).

An appendectomy is a procedure used to remove the appendix. Laparoscopic or Keyhole Surgery for the Appendix is the current gold standard treatment.

In rare instances, the doctor will attempt a conservative form of treatment. You will then be asked to return for a follow-up interval appendectomy.

Kidney Infection

Kidney infections caused by bacteria in the urinary system may affect either one or both kidneys.

Patients typically experience pain in the side, lower back, and groin; they also feel pain in the lower abdomen.

Early medical intervention may prevent permanent kidney damage.

Kidney Stones

Kidney Stones develop when minerals and salt build up in the kidney to form hard lumps or stones.

Kidney stone sizes may vary drastically.

Smaller stones can easily pass through the urinary system; however, larger stones tend to get stuck, causing sharp pain around the side, lower back, abdomen, and groin.

The pain’s severity and location change as the stones move throughout the urinary system.


A hernia occurs when an internal body part protrudes through a weakened muscle or tissue wall creating a small lump. Hernias are usually harmless and most commonly happen in the abdominal area and the Inguinal areas. They will usually need Surgery.

Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a chronic digestive system condition that causes abdominal pain.

Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) refers to conditions including Ulcerative colitis and Crohn’s disease that affect the digestive system. Both conditions cause inflammation of the gut and cause lower abdominal pain.

Endometriosis is a chronic condition that occurs when the womb lining tissue exists in other areas, such as the ovaries or the stomach. It causes pain in the lower abdomen or back.

Pelvic Inflammatory Disease

Pelvic inflammatory disease defines infection of the genital tract, usually causing abdominal pain.

Ectopic Pregnancy

An ectopic pregnancy occurs when a fertilized egg (embryo) is present outside the womb. The embryo often develops in the fallopian tubes and can cause pain in the abdomen. This can develop into a life-threatening emergency.

Ovarian Torsion

Ovarian torsion is when the ovaries become entangled or twisted upon themselves, restricting blood flow and causing severe pain in the lower abdomen.

Inguinal hernia

Inguinal hernias result when fatty tissue or a part of the bowel pushes through passages located in the lower abdomen resulting in a small lump developing at the top of the thigh. Typically occurring in males, inguinal hernias are the most common hernia type, and they cause abdominal pain. The only treatment is Surgery.

Testicular torsion

Testicular torsion is when the spermatic cords attached to the testicles become twisted, restricting blood flow. Testicular torsion causes abdominal pain and other symptoms like nausea and vomiting. This is a surgical emergency and needs urgent surgery to save the testes.
