Pain on the right side of the abdomen can feel confusing because it may come from several different organs. Sometimes the cause is simple, such as gas, constipation, indigestion, or muscle strain. Other times, right-sided abdominal pain may be related to the appendix, gallbladder, liver, kidney, intestines, or reproductive organs. The key is understanding where the pain is located, how it feels, how long it lasts, and what other symptoms are happening at the same time.
Many people search for this symptom when they are worried about appendicitis, gallstones, kidney stones, or stomach problems. While not every case is serious, pain that is severe, worsening, recurring, or associated with fever, vomiting, chest pain, blood in the stool, or yellowing of the skin should be evaluated promptly.

Important Note
Right-sided abdominal pain can be mild and temporary, but it can also be an early sign of a condition that needs medical care. If pain is severe, keeps coming back, or appears with fever, vomiting, weakness, blood in stool, or worsening discomfort, it is better to be evaluated rather than guessing the cause.
Understanding Right-Sided Abdominal Pain
The right side of the abdomen contains several important structures. The upper right abdomen includes the liver and gallbladder. The lower right abdomen includes the appendix and part of the colon. The right kidney sits more toward the back and side. In women, the right ovary and fallopian tube can also cause pain in this area.
This is why the exact location matters. Pain under the right ribs may suggest gallbladder or liver involvement. Pain in the lower right abdomen may raise concern for appendicitis. Pain that starts in the back and moves toward the groin may be related to kidney stones. Cramping with bloating may suggest gas, constipation, food intolerance, or irritable bowel syndrome.

Appendicitis
Appendicitis is one of the most serious causes of pain in the lower right abdomen. The appendix is a small pouch attached to the large intestine. When it becomes inflamed or infected, symptoms may begin as vague discomfort near the belly button before moving to the lower right side.
Appendicitis pain often becomes stronger over several hours. It may worsen when walking, coughing, pressing on the abdomen, or moving suddenly. Other symptoms may include nausea, vomiting, fever, loss of appetite, bloating, constipation, or diarrhea.
Appendicitis requires urgent medical attention because the appendix can rupture if left untreated. A ruptured appendix can lead to infection inside the abdomen and serious complications. If lower right abdominal pain is getting worse and comes with fever, nausea, or vomiting, seek medical care immediately.
Gallbladder Disease and Gallstones
The gallbladder is located in the upper right abdomen beneath the liver. Its job is to store bile, which helps digest fats. Gallstones can form inside the gallbladder and sometimes block bile flow, causing sudden pain known as a gallbladder attack.
Gallbladder pain is often felt under the right rib cage and may spread to the back or right shoulder. It commonly appears after fatty, fried, or greasy meals. Many people also experience nausea, vomiting, bloating, burping, or indigestion during an attack.
Gallbladder symptoms can come and go, but repeated attacks should not be ignored. If pain lasts several hours, is severe, or comes with fever, chills, or yellowing of the skin or eyes, urgent medical evaluation is important.
Liver-Related Pain
The liver occupies much of the upper right abdomen. Liver-related pain is usually described as a dull ache, pressure, fullness, or discomfort beneath the right ribs. Some liver conditions do not cause pain early, which is why other symptoms and routine testing can be important.
Possible liver-related causes include fatty liver disease, hepatitis, liver inflammation, infections, or enlargement of the liver. Symptoms may include fatigue, nausea, loss of appetite, dark urine, pale stools, itching, swelling, or yellowing of the skin or eyes.
Because liver problems can develop quietly, patients with risk factors such as diabetes, obesity, high cholesterol, alcohol use, or abnormal liver tests should follow up with a healthcare provider regularly.

Important Note
Not all right-sided abdominal pain comes from the stomach. The gallbladder, liver, appendix, kidney, colon, and reproductive organs can all create pain in this area. Because symptoms often overlap, proper evaluation is the safest way to identify the real cause.
Kidney Stones and Kidney Infection
Kidney stones can cause sharp, severe pain on the right side, especially if the stone is located in the right kidney or ureter. The pain often starts in the back or side and may travel toward the lower abdomen or groin. It may come in waves and feel intense enough to make it difficult to sit still.
Other symptoms of kidney stones may include nausea, vomiting, frequent urination, burning with urination, cloudy urine, or blood in the urine. Some people feel pressure or urgency even when very little urine comes out.
A kidney infection can also cause right-sided abdominal or flank pain. Symptoms may include fever, chills, fatigue, painful urination, frequent urination, and feeling generally ill. Kidney infections should be treated promptly because they can worsen and spread if ignored.
Gas, Constipation, and Digestive Problems
Digestive issues are among the most common causes of abdominal pain. Gas can become trapped in the intestines and create pressure, cramping, or sharp discomfort on either side of the abdomen. Constipation can also cause right-sided pain, especially when stool builds up in the colon.
Irritable bowel syndrome, food intolerance, stomach infections, acid reflux, gastritis, and intestinal inflammation can all cause abdominal discomfort. The pain may be associated with bloating, diarrhea, constipation, nausea, heartburn, loss of appetite, or changes in bowel habits.
Stress and anxiety may also affect digestion. Some patients notice that abdominal discomfort becomes worse during stressful periods. If stress-related symptoms are affecting your health, you can read more here: Anxiety-Related Issues.
Women’s Health Causes
In women, pain on the right side of the lower abdomen may sometimes be related to the right ovary or fallopian tube. Possible causes include ovulation pain, ovarian cysts, endometriosis, pelvic inflammatory disease, ectopic pregnancy, or other gynecological conditions.
Ovulation pain is usually mild and temporary, but ovarian cysts can cause pressure, sharp pain, bloating, or pelvic discomfort. Severe one-sided pelvic pain, fainting, heavy bleeding, fever, or shoulder pain may require urgent care, especially if pregnancy is possible.
Because abdominal and pelvic symptoms can overlap, women with persistent or severe right-sided pain should seek medical evaluation to determine whether the cause is digestive, urinary, reproductive, or another condition.
When Should You Worry About Right-Sided Abdominal Pain?
You should worry more when the pain is severe, sudden, worsening, or persistent. Mild gas pain may improve with movement, bowel movement, hydration, or time. However, pain that continues to intensify or appears with other concerning symptoms should not be ignored.
Seek urgent medical care if right-sided abdominal pain comes with fever, vomiting, fainting, chest pain, shortness of breath, black stools, blood in stool, severe weakness, dehydration, confusion, yellow skin or eyes, severe right shoulder pain, or pain that prevents you from standing upright.
Patients with chronic conditions such as diabetes, high blood pressure, or heart disease should be especially careful when symptoms are unusual or severe. For related health information, visit Type 2 Diabetes Symptoms and Management and High Blood Pressure Signs.
How Doctors Diagnose the Cause
Diagnosis begins with a detailed conversation about your symptoms. Your provider may ask where the pain is located, when it started, whether it is sharp or dull, whether it moves to the back or shoulder, whether eating makes it worse, and whether you have fever, nausea, vomiting, diarrhea, constipation, urinary symptoms, or weight changes.
A physical exam can help identify tenderness, swelling, guarding, or signs that may suggest appendicitis, gallbladder disease, kidney problems, or digestive causes. Depending on the situation, testing may include blood work, urine testing, liver function testing, stool testing, ultrasound, CT scan, or other imaging.
The goal is to avoid guessing. Many conditions can feel similar, so testing may be necessary to confirm the cause and choose the right treatment.
Treatment Options
Treatment depends on the diagnosis. Gas and constipation may improve with hydration, movement, fiber changes, and dietary adjustments. Acid reflux, gastritis, or indigestion may require meal changes, avoiding trigger foods, or medication. IBS may require a personalized plan that includes diet, stress management, and symptom control.
Kidney infections may require antibiotics. Kidney stones may require pain control, hydration, imaging, and sometimes a procedure depending on size and location. Gallbladder disease may require dietary changes, monitoring, or surgical evaluation if attacks continue. Appendicitis usually requires urgent treatment.
Because the causes are so different, persistent right-sided abdominal pain should be evaluated instead of treated repeatedly with over-the-counter medicine without knowing the reason.
