Right Side Pain Under Ribs in Females: Causes & Red Flags

That dull ache under your right ribs keeps nagging, or a sharp jab stopped you mid-step. Right side pain under the ribs can be anything from a gas bubble to a gallbladder signal needing attention.

Common causes listed by Northwell Health: 12 ·
Red flags in abdominal pain (Ubie Doctor’s Note): 3 ·
Signs of pancreatitis per NIDDK: 2

Four key facts, one pattern: the most common culprits are gallbladder and liver, but in women, gynecological causes are often overlooked.

What Organs Are Located Under the Right Rib Cage in Females?

Understanding anatomy is the first step. The right upper quadrant (RUQ) of your abdomen houses several organs that can produce pain when irritated. The largest is the liver, which stretches across the upper right abdomen and is partly protected by the rib cage. Directly beneath the liver sits the gallbladder, a small pear-shaped pouch that stores bile. Behind the liver, tucked toward the back, is the right kidney. A portion of the colon (the hepatic flexure) curves along the ribs, and the diaphragm muscle separates the abdominal organs from the lungs above it.

Liver and gallbladder

• The liver is the largest organ under the right rib cage
• The gallbladder sits directly beneath the liver
• Gallstones blocking the cystic duct cause sharp pain after fatty meals (Cypress Cardiovascular Institute (cardiology practice))

Right kidney and adrenal gland

• The right kidney is located behind the liver, making kidney stones and infections a possible cause of RUQ pain
• Renal colic from right kidney stones can radiate to the lower back and side (Tuasaude (health portal))

Part of the colon and diaphragm

• Gas trapped in the hepatic flexure of the colon can produce cramping under the ribs (Medical News Today (health journalism))
• The diaphragm can become irritated by conditions like pneumonia, referred pain to the right shoulder

The implication: knowing which organ is likely involved helps narrow down whether the pain is a passing discomfort or something that needs imaging.

Why Does My Right Side Hurt Under My Ribs? Common Causes

Most RUQ pain falls into one of a handful of categories. A 2024 breakdown from Northwell Health (gastroenterology department) lists 12 common causes, with rib injuries and heartburn at the top. Here are the ones you’re most likely to encounter.

Gallstones and gallbladder disease

• Gallstones can cause severe pain that lasts 30 minutes to several hours, especially after a fatty meal
• Gallbladder inflammation (cholecystitis) often presents with tenderness when pressing under the right ribs

Costochondritis and rib injuries

• Costochondritis is inflammation of the cartilage that connects the ribs to the sternum (Narayana Health (hospital network))
• Rib fractures or bruises from accident or heavy lifting cause localized sharp pain

Gastrointestinal issues (heartburn, gas)

• Gastroesophageal reflux disease (GERD) can produce a burning sensation that reaches under the right ribs
• Gas buildup in the large intestine often causes a dull, shifting discomfort

Kidney stones and infections

• A right kidney stone can cause colicky pain that radiates from the flank to the front under the ribs (Tuasaude (health portal))
• Pyelonephritis (kidney infection) often adds fever and nausea to the pain picture

Female-specific gynecological causes

• Cleveland Clinic lists ovarian cysts, endometriosis, pelvic inflammatory disease, Fitz-Hugh-Curtis syndrome, and ectopic pregnancy as causes of right-sided pain that can mimic RUQ pain
• Fitz-Hugh-Curtis syndrome involves inflammation of the liver capsule from pelvic infection, causing right upper quadrant pain

The pattern: the most frequent causes are musculoskeletal or biliary, but the gynecological component is what makes female patients different.

Does Pancreatitis Cause Pain Under the Ribs? Symptoms and Signs

Pancreatitis is often associated with upper abdominal pain, but it can feel like rib pain, especially when the tail of the pancreas is involved. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) (research institute) describes pancreatitis pain as severe upper abdominal pain that often radiates to the back. Because the pancreas sits behind the stomach, its head lies close to the right side, near the liver.

How pancreatitis pain feels

• Acute pancreatitis pain is sudden, severe, and often described as boring through to the back
• Many patients report that the pain worsens after eating or when lying flat (NHS (national health service))
• Chronic pancreatitis causes persistent dull pain with occasional flare-ups

Two key signs of pancreatitis

• The two most common signs: severe upper abdominal pain and vomiting
• A third sign is tenderness when the abdomen is pressed

Chronic pancreatitis vs. acute pancreatitis

• Acute pancreatitis comes on fast and is usually caused by gallstones or heavy alcohol use
• Chronic pancreatitis develops over years, leading to fatty stools and weight loss

The catch: pancreatitis pain can be mistaken for gallstone pain because both strike after fatty meals. The key difference is radiation: gallstone pain tends to stay in the front, while pancreatitis pain bores through to the back.

When Should You Go to the ER for Right Side Rib Pain? Red Flags

Knowing when to stop Googling and head to the hospital can be life-saving. The Ubie Doctor’s Note (clinical decision support tool) defines three red flags in abdominal pain: fever, persistent vomiting, and severe pain that comes on suddenly. Cleveland Clinic adds jaundice (yellowing of the skin or eyes), blood in urine or stool, and shortness of breath as additional signals.

Three red flags in abdominal pain

• Fever (over 100.4°F) with pain could indicate infection
• Vomiting that prevents keeping down fluids leads to dehydration
• Severe pain that makes it hard to stand or breathe

Fever and chills

• Fever with right rib pain suggests cholecystitis, pyelonephritis, or pneumonia
• Rib pain with fever and cough may point to a lung infection or pulmonary embolism

Inability to keep down fluids

• If you cannot drink water without vomiting, you risk electrolyte imbalance and need IV fluids

Sudden, severe or worsening pain

• Pain that makes you double over or that comes on in minutes is a hallmark of organ perforation or rupture
• Jaundice means bile duct obstruction – a medical emergency

The trade-off: many causes are self-limiting, but the red flags exist precisely because some causes (gallbladder rupture, pancreatitis, ectopic pregnancy) can turn deadly within hours.

How Is Right Side Pain Under the Ribs Diagnosed and Treated?

Once you’re in a doctor’s office, the workup follows a fairly standard path. Cleveland Clinic recommends ultrasound as the first-line imaging for gallbladder issues because it’s fast, radiation-free, and highly accurate for gallstones. Blood tests assess liver enzymes, bilirubin, and pancreatic amylase/lipase.

Imaging tests (ultrasound, CT, MRI)

• Ultrasound is the go-to for gallbladder and biliary tree
• CT scan provides a broader view of the abdomen and is used if pancreatitis or kidney stones are suspected (NIDDK (research institute))
• MRI with MRCP gives detailed images of bile and pancreatic ducts without radiation (RadiologyInfo.org (medical imaging resource))

Blood tests for liver and pancreas function

• Elevated bilirubin and alkaline phosphatase point to bile duct obstruction
• Amylase and lipase levels over 3 times the normal limit confirm pancreatitis

Home care and medications

• For simple costochondritis or muscle strain: rest, anti-inflammatories (ibuprofen), and ice packs
• For GERD: antacids and dietary changes (avoid trigger foods)
• For gallstones: low-fat diet until surgical removal (cholecystectomy) (Cleveland Clinic (health authority))

When to see a specialist

• Gastroenterologist for persistent gallbladder or pancreas issues
• Gynecologist if ovarian or pelvic causes are suspected
• Orthopedist or sports medicine for chronic costochondritis

The implication: early imaging saves unnecessary ER visits and catches serious conditions before complications arise.

Steps to Take When You Feel Right Side Pain Under Your Ribs

1. Assess the severity – Rate your pain on a 1-10 scale. If it’s 7 or higher and came on suddenly, skip the next steps and go to the ER.
2. Check for red flags – Fever, vomiting, jaundice, blood in urine/stool, or shortness of breath? Those demand immediate care.
3. Note the pattern – Does it worsen after eating? When you lie down? On deep breath? That helps your doctor narrow causes.
4. Try simple remedies – For mild pain that seems muscular or from gas, rest, a heating pad, or over-the-counter antacids may help.
5. Call your primary care doctor – If pain persists for more than a few hours or keeps coming back, book an appointment within 24 hours.
6. Prepare for the visit – Write down when the pain started, what you ate, and any other symptoms. That speeds up diagnosis.

What’s Confirmed and What’s Unclear About Right Side Pain Under Ribs in Females

“Rib injuries and heartburn are the most common causes of pain under the right rib cage.”

Gastroenterology department, Northwell Health (health system)

“Three red flags in abdominal pain are fever, vomiting, and severe pain.”

Ubie Doctor’s Note (clinical decision support tool)

“Pancreatitis signs include severe upper abdominal pain that may radiate to the back.”

NIDDK (research institute)

The story of right rib pain is rarely straightforward, especially for women. The gallbladder gets the attention, but the ovaries, fallopian tubes, and even the pelvic floor can send pain signals upward. For any woman with persistent right upper quadrant pain, asking your doctor to consider both gynecological and gastrointestinal causes is the smartest move. The consequence of missing an ectopic pregnancy or a twisted ovarian cyst is not just discomfort – it’s a life-threatening delay.
