What is Gallbladder Inflammation (Cholecystitis)? What are the Symptoms and Treatment Methods for Gallbladder Inflammation?
Gallbladder inflammation (cholecystitis) is an inflammatory condition that usually develops when a gallstone (cholelithiasis) blocks the gallbladder outlet and can lead to serious complications if not treated in time. Acute cholecystitis usually presents with sudden onset of right upper abdominal pain, fever, and nausea, while chronic cholecystitis is associated with recurrent attacks and prolonged low-grade inflammation.
What is the Gallbladder?
The gallbladder is a small organ located on the underside of the liver, which stores the bile produced by the liver and helps digest fat by emptying it into the duodenum after meals, especially fatty foods. The bile in the gallbladder consists of cholesterol, bile acids and pigments; disruption of the balance of its contents paves the way for the formation of cholesterol stones. When these stones block the bladder neck or cystic duct, pain, inflammation, and infection can develop. Gallstones are a common problem and risk factors include the female sex, advanced age, obesity and rapid weight loss.
What is Gallbladder Inflammation (Cholecystitis)?
Cholecystitis is acute or chronic inflammation of the gallbladder. The most common cause is temporary or permanent obstruction of the cystic duct by gallstones; as a result, intra-gallbladder pressure increases, wall blood flow is disrupted and an environment suitable for bacterial growth is created. Acute cholecystitis presents with a sudden onset of symptoms; chronic cholecystitis is characterized by permanent wall damage resulting from recurrent stone obstructions. Acalculous cholecystitis, which is less common, develops without stones, especially in critically ill patients in intensive care, and may have a more severe course.
How Does Gallbladder Inflammation (Cholecystitis) Occur?
The main mechanism in pathogenesis is obstruction of the cystic duct by stones. Obstruction prevents bile flow, the gallbladder swells, wall edema and ischemia develop, which triggers a local inflammatory response. If timely intervention is not provided, complications such as necrosis (gangrene) of the gallbladder wall, perforation and surrounding tissue infection may occur. In acalculous cases, bile stasis and ischemia are at the forefront as a result of serious illness, prolonged fasting/TPN, sepsis, trauma or burns. This process manifests itself with typical signs on ultrasonography, such as wall thickening, pericholecystic fluid, and sonographic Murphy's sign.
What are the Symptoms of Gallbladder Inflammation (Cholecystitis)?
Symptoms of acute cholecystitis usually begin suddenly and become increasingly severe. Pain radiating to the right upper quadrant and right shoulder, nausea and vomiting, fever and general weakness are common. On examination, increased tenderness in the right upper quadrant during deep breathing, called the “Murphy's sign,” supports the diagnosis. If the stone also obstructs the bile duct, jaundice and darkening of the urine color may be added. The condition may be more insidious, especially in advanced age and in the presence of diabetes, so clinical suspicion is important.
General symptoms include:
- Right upper abdominal pain and colic pain: Gallbladder pain may initially be “colic” and transient, but as the obstruction continues, it becomes constant, increasing, and radiating to the right shoulder/back.
- Fever, nausea, vomiting and loss of appetite: These are signs of systemic inflammation; especially fever and chills suggest that infection is present.
- Jaundice (icterus): If gallstones pass into the common bile duct or edema causes obstruction, yellowing of the skin and eyes, dark urine, and light-colored stools may occur. This situation suggests the presence of a choledochal stone in addition to cholecystitis.
- Sensitivity and Murphy's sign: Pain in the right upper quadrant that increases with deep breathing during ultrasound or examination is typical, and valuable in diagnosis.
What Causes Gallbladder Inflammation (Cholecystitis)?
The most common cause of cholecystitis is gallstones. In addition, lifestyle and some medical conditions increase the risk of stones and cholecystitis. Knowing the risk factors is important for both prevention and early referral.
- Gallstones (cholelithiasis): Most acute cholecystitis occurs when a stone obstructs the cystic duct. The female sex, advanced age, obesity, pregnancy, rapid weight loss and hemolytic anemia increase the risk of stones.
- Acalculous cholecystitis: Develops without stones; occurs in conditions such as critical illness, sepsis, trauma, prolonged hunger/TPN and vascular ischemia and is often more severe.
- Bile stasis and infection: When bile flow stops after obstruction, bacterial proliferation becomes easier and gallbladder infection may be added to the picture. This condition can lead to rapid deterioration, especially in diabetes and advanced age.
How to Prevent Gallbladder Inflammation (Cholecystitis)?
Although it is not possible to prevent it completely, the risk can be reduced. A balanced diet, regular physical activity, and avoiding rapid weight loss are key approaches, as extremely low-calorie diets and rapid weight loss after bariatric surgery can trigger stone formation. A dietary pattern rich in fiber, rich in fruits and vegetables, and low in saturated fat (e.g. Mediterranean diet) is recommended. Routine surgery may not be necessary in individuals with gallstones but without symptoms; the decision should be individualized based on symptoms, stone characteristics, and associated risks.
How is Gallbladder Inflammation (Cholecystitis) Treated?
Clinical findings, laboratory tests and imaging are evaluated together in diagnosis. The Tokyo Guidelines 2018 (TG18) use a combination of “local inflammatory findings (RUQ pain/Murphy), systemic inflammation (fever, CRP, leukocytosis), and support by imaging” as the basis for diagnosis; they also classify disease severity. The first choice for imaging is abdominal ultrasound; findings such as wall thickening, pericholecystic fluid, and stones/biliary sludge are sought. HIDA scintigraphy or CT/MRI may be considered in cases where ultrasound is inadequate or complications are suspected; the ACR Appropriateness Criteria recommend ultrasound as first-line treatment for acute right upper quadrant pain.
How is Gallbladder Inflammation (Cholecystitis) Treated?
The basis of treatment is early laparoscopic cholecystectomy; guidelines state that surgery within the first hours to days after diagnosis in appropriate patients reduces complications and readmissions. Supportive treatments include intravenous fluids, pain control, broad-spectrum antibiotics necessary fpr patients, and discontinuation of oral intake. Percutaneous cholecystostomy (temporary drainage) can be applied as a bridge treatment in selected patients with high surgical risk or sepsis; in cases of suspected choledochal stones, confirmation with EUS/MRCP and endoscopic treatment (ERCP) are considered.
Frequently Asked Questions About Gallbladder Inflammation (Cholecystitis)
Does gallbladder inflammation recur?
Once cholecystitis has occurred in the presence of gallstones, the risk of recurrence is high unless the gallbladder is removed. Over time, recurrent attacks can lead to chronic cholecystitis, which is characterized by persistent indigestion, dyspepsia, and intermittent “biliary colic” pain. Laparoscopic cholecystectomy is an effective solution to prevent both recurrent attacks and serious complications such as gangrene/perforation.
Can gallbladder inflammation be cured without surgery?
In selected mild cases, temporary improvement can be achieved with medical treatment (fluids, analgesics, antibiotics); however, if the underlying cause is gallstones, the likelihood of recurrence of attacks is high. Current guidelines recommend early laparoscopic cholecystectomy as the standard approach in appropriate patients; temporary drainage (percutaneous cholecystostomy) may serve as a bridge in high-risk patients.
Which foods should be avoided in case of gallbladder inflammation?
During an acute attack, fatty, fried and processed foods can stimulate bile flow and exacerbate pain; therefore, low-fat, fiber-rich, small and frequent meals should be preferred. Since personal tolerance is important, trigger foods (excessive spices, high-fat dairy products, fatty meats) should be identified by gradual testing. Adequate fluid intake, fruit and vegetable consumption and whole grain consumption support digestion.
What is the difference between gallstones and cholecystitis?
Gallstones (cholelithiasis) refer to the presence of stones in the gallbladder and are often asymptomatic. Cholecystitis is the clinical picture in which the stone (or rarely without the stone) initiates inflammation; it progresses with pain, fever and laboratory-imaging findings. Routine surgery may not be necessary in individuals with stones detected but without symptoms; surgical treatment is the first choice in symptomatic patients with stones and cholecystitis.
Does gallbladder inflammation lead to cancer?
Cholecystitis is not directly cancerous, but long-term presence of stones and chronic inflammation are considered risk factors for gallbladder cancer. Although widespread wall calcification, specifically the so-called “porcelain gallbladder,” has been associated with cancer, new data suggest that the risk may be lower than previously thought; therefore, the decision should be based on symptoms, calcification pattern, and patient characteristics.
How should a patient whose gallbladder has been removed be fed?
In the first weeks after cholecystectomy, low-fat, small, frequent meals facilitate digestion; over time, a gradual transition to a normal, balanced diet can be made. Fiber intake (especially soluble fiber) should be increased, but increased slowly to avoid gas-cramps. Some people may experience temporary diarrhea; in this case, limiting fatty and very spicy foods and consuming coffee and alcohol in moderation are helpful.
