Cholecystolithiasis 9 × Is 7mm normal?

summary

Cholecystolithiasis 9 × How big is 7mm? This is a common problem. Gallbladder stone is a common disease and frequently occurring disease. It is more common in northern and city populations. The incidence rate of natural population is more than 10%, and that of women is more than that of men. It is about 3:1. Let's share about 9 cases of gallstone × Is 7mm normal? Let's go.

Cholecystolithiasis 9 × Is 7mm normal?

First, let's understand the position of gallbladder in human body and its physiological function. The gallbladder is pear shaped, about 7-9cm long and 2.5-3.5cm wide, with a volume of 30-50ML. The bottom is free, the body is located in the gallbladder bed on the visceral surface of the liver, and the neck is cystic and connected with the cystic duct, which is called Hartmann's bag, where the stones are often embedded.

Second: the gallbladder is a digestive organ in the human body. It not only has the function of storing, concentrating and excreting bile, but also plays an important role in regulating the pressure of bile duct inside and outside the liver when there is obstruction at the lower end of the common bile duct.

Thirdly, the causes of gallstone formation are complex, and most of them are cholesterol stones. In normal condition, there is a dynamic balance between the forces of promoting and resisting cholesterol crystallization and polymerization in gallbladder. However, in some pathological cases, the change of various components in bile, especially the change of bile salt and cholesterol in bile, is an important factor in the formation of gallstones. Of course, the formation of gallstones is also related to the increase of cholesterol, unconjugated bilirubin, parasites and bacterial infection of biliary tract.

matters needing attention

1. Women. About 70% of gallstone patients are female. The more pregnant times, the higher the incidence rate is due to high estrogen level in women. 2. Age of onset. Most epidemiological studies show that the incidence rate of gallstones increases with age. This disease is rare in childhood. The incidence rate of 40~69 is 4 times that of the younger age group at 5 years of age. 3. Obesity. The incidence rate of gallstones is 5 times higher than that of normal people in those who are overweight and overweight. The incidence of gallstones is 15% times higher than that of normal people. The incidence rate of gallstones in obese women aged 20 to 30 is 5-6 times higher than that of normal weight peers. The reason is that the cholesterol conversion rate of obese people is higher than that of normal people, which makes the increase of cholesterol excretion in bile easily precipitate, and easy to form stones.
