Gallbladder Disease

What is Gallbladder Disease?

Gallbladder disease is a term used to describe a range of conditions that affect the gallbladder, an organ beneath the liver. It plays a crucial role in the digestive process by storing and releasing bile, a substance produced by the liver that aids in the digestion of fats.


Gallbladder disease can encompass various conditions and disorders that affect the gallbladder's normal functioning. 


Impact of Gallbladder Diseases on Anatomy and Health

When gallbladder disease occurs, it can affect the anatomy in the following ways:

  • Gallstones: These hardened deposits can block the bile duct, causing pain and inflammation. Severe cases may require surgical removal of the gallbladder.
  • Cholecystitis: Inflammation of the gallbladder can lead to swelling and irritation of the organ, making it less efficient in storing and releasing bile.
  • Biliary Dyskinesia: This condition involves abnormal gallbladder contractions, which can disrupt the normal flow of bile and lead to discomfort.
  • Gallbladder Polyps: These growths can alter the structure of the gallbladder's inner lining and may require monitoring or removal, depending on their nature.


Gallbladder disease can have various effects on your health:

  • Pain: One of the most common symptoms of gallbladder disease is abdominal pain, typically in the upper right or centre of the abdomen. This pain can be intense and may radiate to the back or shoulder blades.
  • Digestive Issues: The disruption of bile flow can lead to difficulties digesting fats, resulting in symptoms like bloating, nausea, and diarrhoea.
  • Infections: If left untreated, cholecystitis can lead to infections and more severe complications.
  • Complications: Severe cases of gallbladder disease can lead to complications such as pancreatitis, jaundice (yellowing of the skin and eyes), and even gallbladder rupture, a medical emergency.


Types of Gallbladder Disease

There are several types of gallbladder diseases, including:

Gallstones

Gallstones are hard particles that develop in the gallbladder. They occur when substances in bile (such as cholesterol and bilirubin) crystallise. Gallstones can range in size and may not always cause symptoms. However, if a stone blocks a bile duct, it can cause severe pain, jaundice, and infection.


Cholecystitis

This condition is characterised by gallbladder inflammation, usually due to gallstones blocking the tube leading out of the gallbladder. Symptoms often include severe pain in the upper right abdomen, fever, nausea, and vomiting. If untreated, it can lead to serious complications, such as a gallbladder rupture.


Choledocholithiasis

This condition occurs when gallstones move into or form in the common bile duct, which is the tube that carries bile from the gallbladder and liver to the small intestine. This can lead to jaundice, infection, and severe abdominal pain.


Biliary Dyskinesia

This condition is characterised by the gallbladder not emptying properly. Symptoms can mimic gallstones, including abdominal pain, nausea, and bloating. This condition often leads to the removal of the gallbladder.


Gallbladder Polyps

Polyps are growths that protrude from the gallbladder lining. Most gallbladder polyps are harmless and don't cause symptoms. However, larger ones or those that grow rapidly might require surgery due to the risk of gallbladder cancer.


Gallbladder Cancer

This rare type of cancer is difficult to diagnose because it often causes no specific early symptoms. Gallbladder cancer is often discovered at a late stage when the cancer has spread to other areas like the liver. Risk factors for gallbladder cancer include a history of gallstones and other gallbladder conditions.


Causes and Risk Factors for Gallbladder Disease

Gallbladder disease affects individuals differently, with certain factors increasing susceptibility. Here are the key risk factors:

  • Gender: Women are more prone to gallbladder disease than men. Hormonal shifts, like those during pregnancy, the use of birth control pills, or hormone replacement therapy, can elevate the risk.
  • Age: Gallbladder disease is prevalent among older adults, particularly those aged 60 and above.
  • Obesity: Being overweight or obese significantly heightens the risk. Excess body fat can boost cholesterol production, contributing to gallstone formation.
  • Rapid Weight Loss: Swift weight loss, whether through crash diets or bariatric surgery, raises the risk of gallstone development.
  • Family History: Genetic factors can influence susceptibility. A family history of gallstones or gallbladder disease may increase your risk.
  • Diet: Diets rich in saturated fats and cholesterol while lacking in fibre can contribute to gallstone formation. Opt for diets abundant in fruits, vegetables, and whole grains to lower your risk.
  • Medical Conditions: Certain conditions like diabetes and metabolic syndrome can elevate the risk of gallbladder disease.
  • Ethnicity: Some ethnic groups, including Native Americans and Mexican Americans, have a higher predisposition to gallstones.


Symptoms of Gallbladder Diseases

Symptoms of gallbladder diseases can vary depending on the specific ailment. However, some common symptoms that might be experienced with gallbladder diseases include:

  • Pain: This is usually located in the upper right or centre abdomen, often following a meal, especially a fatty one. The pain might also be felt in the right shoulder or back. It can vary from mild to severe and lasts minutes to hours.
  • Indigestion: Symptoms of indigestion can include bloating, gas, heartburn, and feeling full quickly when eating.
  • Nausea and vomiting are common, especially if the gallbladder is inflamed.
  • Fever or chills: An elevated temperature could indicate an infection, usually in the case of acute cholecystitis.
  • Jaundice: This is a yellowing of the skin and whites of the eyes and can occur if a gallstone passes out of the gallbladder and blocks the bile duct.
  • Changes in bowel movement and urine: Stools may become lighter-coloured, and urine may become darker if the bile flow is blocked.
  • Chronic diarrhoea: More than four bowel movements daily for at least three months may indicate chronic gallbladder disease.


These symptoms can be episodic or chronic, and the intensity can vary from person to person. In some cases, gallstones may cause no symptoms, a condition called "silent gallstones."


Diagnosis of Gallbladder Diseases

For the diagnosis of gallbladder diseases, doctors use several tests and procedures:

  • Medical history and physical exam: The doctor will ask about your health habits, past illnesses, and treatments. They will also examine your body to check general signs of health and for any unusual lumps.
  • Blood tests can reveal evidence of bile duct blockage, liver dysfunction, or infection.
  • Imaging tests: These might include an ultrasound, computerised tomography (CT) scan, magnetic resonance imaging (MRI), or a specialised procedure called endoscopic retrograde cholangiopancreatography (ERCP). These tests create pictures of the gallbladder and surrounding structures, often revealing gallstones or inflammation.
  • HIDA scan (hepatobiliary iminodiacetic acid scan): This test tracks the production and flow of bile from your liver to your small intestine and shows blockage.
  • Biopsy: In cases where gallbladder cancer is suspected, a biopsy may be conducted where a small tissue sample is removed and examined under a microscope.
  • Laparoscopy: A small camera is inserted through a small incision in the abdomen to visualise the gallbladder and surrounding structures.


Treatment for Gallbladder Diseases

Treatment for gallbladder disease depends on the specific condition. Common approaches include:

  • Dietary Changes: For mild cases or as preventive measures, dietary modifications to reduce fat intake may be recommended.
  • Medications: Medications can be prescribed to dissolve gallstones or manage symptoms.
  • Surgery: In more severe cases, surgical removal of the gallbladder (cholecystectomy) may be necessary. This procedure is common and generally well-tolerated, as the body can adapt to digesting fats without the gallbladder.


What if Gallbladder Diseases are Untreated?

If gallbladder conditions are left untreated, they can lead to serious complications, such as:

  • Infection or Abscess: If a gallstone blocks the ducts, bacteria may accumulate in the gallbladder, leading to a severe infection or an abscess.
  • Gallbladder Inflammation (Cholecystitis): Untreated gallstones can cause the gallbladder to become inflamed, leading to severe pain, fever, and jaundice.
  • Bile Duct Infection (Cholangitis): If gallstones block the bile ducts, bile can back up into the liver, causing a serious infection.
  • Pancreatitis: Gallstones can block the pancreatic duct, leading to inflammation of the pancreas, a serious condition that requires immediate treatment.
  • Gallbladder Cancer: Although rare, gallstones increase the risk of gallbladder cancer.


It’s important to seek medical advice if you're experiencing symptoms that could be related to a gallbladder disease. The gallbladder is not a vital organ, and its removal will not significantly affect your ability to live a normal, healthy life. After removing the gallbladder, bile flows directly from the liver into the small intestine rather than stored in the gallbladder.
