Final answer:
Cholecystitis is caused by inflammation of the gallbladder due to gallstones blocking the bile ducts. The risk factors for cholecystitis and cholelithiasis include factors such as age, gender, obesity, family history, ethnicity, diet, and certain medical conditions.
Step-by-step explanation:
The Cause of Cholecystitis & Cholelithiasis
Cholecystitis is inflammation of the gallbladder, usually caused by gallstones blocking the bile ducts. Cholelithiasis, or gallstone formation, occurs when there is an imbalance in bile composition, leading to the formation of solid particles in the gallbladder. The most common type of gallstones are made up largely of cholesterol, along with small amounts of calcium salts, glycerophospholipids, and fatty acids.
Eight Risk Factors of Cholecystitis & Cholelithiasis
1. **Gender**: Women are more likely than men to develop gallstones.
2. **Age**: Gallstones become more common as you get older.
3. **Obesity**: Excess weight increases the risk of gallstones.
4. **Rapid weight loss or fasting**: Losing weight too quickly or prolonged fasting can lead to gallstone formation.
5. **Family history**: Having a family history of gallstones increases the risk.
6. **Ethnicity**: Certain ethnic groups, such as Native Americans and Mexican Americans, have a higher risk.
7. **High fat diet**: Consuming a diet high in saturated fats and cholesterol can contribute to gallstone formation.
8. **Certain medical conditions**: Conditions like diabetes and liver disease can increase the risk of gallstones.
