Questions such as “Why does my right side hurt?”, “Could it be appendicitis?”, or “Should I go to the emergency room for abdominal pain?” are extremely common. Understanding the possible causes, symptoms, and warning signs can help you determine when to seek medical care.

Understanding the Right Side of the Abdomen
The abdomen is divided into different regions. Pain location often provides clues about the underlying problem.
Upper Right Abdomen Contains:
- Liver
- Gallbladder
- Part of the pancreas
- Part of the small intestine
- Part of the colon
Lower Right Abdomen Contains:
- Appendix
- Small intestine
- Colon
- Right ureter
- Reproductive organs in women
Knowing where the pain occurs helps healthcare providers narrow down possible causes.
1. Appendicitis
Appendicitis is one of the most important causes of right lower abdominal pain.
The appendix is a small pouch attached to the large intestine. When it becomes inflamed, prompt treatment is often necessary.
Symptoms of Appendicitis
- Pain that begins near the belly button
- Pain moving to the lower right abdomen
- Fever
- Nausea
- Vomiting
- Loss of appetite
- Worsening pain with movement
Appendicitis is considered a medical emergency because a ruptured appendix can lead to serious infection.
2. Gallstones and Gallbladder Disease
The gallbladder sits beneath the liver in the upper right abdomen.
Gallstones can block the flow of bile and cause intense pain.
Common Symptoms
- Upper right abdominal pain
- Pain after eating fatty foods
- Nausea
- Vomiting
- Bloating
- Pain radiating to the right shoulder or back
Gallbladder attacks often occur suddenly and may last from minutes to several hours.
3. Liver Disorders
Several liver conditions can cause right upper abdominal discomfort.
Examples include:
- Fatty liver disease
- Hepatitis
- Liver inflammation
- Liver enlargement
- Cirrhosis
Associated Symptoms
- Fatigue
- Yellowing of the eyes or skin
- Abdominal fullness
- Swelling
- Nausea
Persistent right upper abdominal pain should be evaluated by a healthcare provider.
4. Kidney Stones
Kidney stones can cause severe pain when they move through the urinary tract.
Symptoms
- Sharp pain in the side or back
- Pain radiating toward the groin
- Blood in urine
- Nausea
- Vomiting
- Frequent urination
Many patients describe kidney stone pain as one of the most intense forms of pain.
5. Urinary Tract Infection (UTI)
A urinary tract infection can cause pain in the lower abdomen and pelvic region.
Common Symptoms
- Burning with urination
- Frequent urination
- Lower abdominal discomfort
- Cloudy urine
- Fever
If the infection spreads to the kidneys, right-sided abdominal or flank pain may occur.
6. Constipation
Constipation is a surprisingly common cause of abdominal discomfort.
When stool accumulates in the intestines, symptoms may include:
- Bloating
- Cramping
- Right-sided discomfort
- Fullness
- Difficulty passing stool
Improving hydration, fiber intake, and physical activity often helps relieve symptoms.
7. Gas and Bloating
Gas trapped in the intestines can produce pain anywhere in the abdomen.
Symptoms often include:
- Abdominal pressure
- Bloating
- Gurgling sounds
- Burping
- Excessive gas
Gas-related pain may move from one area of the abdomen to another.
8. Irritable Bowel Syndrome (IBS)
IBS is a common digestive disorder that affects the large intestine.
Symptoms

- Bloating
- Diarrhea
- Constipation

Pain can occur on either side of the abdomen and often improves after a bowel movement.
9. Hernias
A hernia occurs when tissue pushes through a weak area in the abdominal wall.
Symptoms
- Localized pain
- Visible bulge
- Discomfort when lifting
- Pain with coughing or straining
Some hernias require surgical repair.
10. Intestinal Infections
Bacterial, viral, and parasitic infections can cause inflammation within the digestive tract.
Symptoms may include:
- Abdominal pain
- Diarrhea
- Nausea
- Vomiting

- Bloating
Most infections improve with supportive care, although some require medical treatment.
11. Crohn’s Disease and Inflammatory Bowel Disease
Crohn’s disease frequently affects the lower right abdomen.
Common Symptoms
- Chronic abdominal pain
- Diarrhea
- Weight loss
- Fatigue
- Rectal bleeding
Early diagnosis helps prevent complications and improve quality of life.
