A very important factor in gallbladder disease is the fluid dynamics of the gallbladder, because the bile viscosity increases at night, especially with a long-term irregular diet, the bile viscosity is high and the bile can be concentrated to more than ten times. Under normal circumstances, the neurohumoral reflex will promote bile emptying during fasting, and if the bile viscosity of the gallbladder is low, emptying is easier; however, if the bile viscosity is too high, it may be difficult to empty the concentrated bile of the gallbladder. It is perfectly possible to do it if you are young and have good gallbladder function, but as time goes on, the gallbladder does not function enough, which will cause compensatory thickening, and by thickening and increasing the power, the thickness of the gallbladder wall will become thicker and thicker as the number of times increases, which is a theory that is currently accepted and acceptable. Adenomyosis of the gallbladder is a hyperplastic change in a certain part of the wall of the gallbladder, which is clinically divided into three types: 1) focal adenomyosis, mostly at the bottom of the gallbladder; 2) segmental adenomyosis, mostly confined to the body of the gallbladder or the jugular abdomen; 3) diffuse adenomyosis. These three are the more common types of adenomyosis in clinical practice. Among these three types of adenomyosis, segmental adenomyosis is the most likely to occur, regardless of whether it is focal, segmental or diffuse adenomyosis, patients should be diagnosed and treated early.
