Anonymous users2024-02-11**。Under normal conditions, pancreatic juice contains inactive pancreatic propancrat in its glandular tissue. Pancreatic juice flows into the duodenum along the pancreatic duct through the common bile duct Oddi's sphincter, and due to the presence of bile in the duodenum and the secretion of an enterokinase by the mucosa of the duodenal wall, pancreatic propancrat begins to transform into a highly active digestive enzyme.
If the outflow tract is blocked and the excretion is not smooth, pancreatitis can be caused.
When the sphincter of Oddi's muscle spasms or the pressure in the bile duct increases, such as stones and tumors, bile will reflux into the pancreatic duct and enter the pancreatic tissue, at this time, the lecithin contained in the bile is broken down into lysolecithin by lecithin A contained in the pancreatic juice, which can have a toxic effect on the pancreas. In biliary tract infections, bacteria can release kinases that activate pancreatic enzymes, which can also be turned into active substances that can damage and dissolve pancreatic tissue. These substances convert the trypsinogen contained in pancreatic juice into trypsin, which has strong digestion activity and penetrates into pancreatic tissue to cause self-digestion, and can also cause pancreatitis.
Acute pancreatitis.
It is an acute inflammation caused by pancreatic digestion of the pancreas and its surrounding tissues, which is mainly manifested as edema and necrosis of the pancreas. The causes are as follows:
1) Biliary system diseases Bile duct inflammation, stones, parasites, edema, spasm and other lesions cause the ampulla to be obstructed, and bile refluxes into the pancreatic duct through a common channel, activating pancreatinogen, thus causing pancreatitis.
2) Alcoholism and overeating Alcoholism and overeating make the secretion of pancreatic juice vigorous, and the drainage of the pancreatic duct is not smooth, resulting in increased pressure of pancreatic juice in the pancreaticobiliary system, resulting in high concentration of protease excretion disorders, and finally leading to the rupture of pancreatic vesicles and the onset of the disease.
3) Injury to the stomach, biliary tract and other abdominal cavities to the pancreas, or cause pancreaticobiliary pressure to be too high.
4) Infection Many infectious diseases can be complicated by acute pancreatitis, and the symptoms are mostly not obvious. If roundworms enter the bile duct or pancreatic duct, they can bring in bacteria, which can activate pancreatic enzymes and cause pancreatic inflammation.
5) Hyperlipidemia and hypercalcemia Hyperlipidemia, embolization of pancreatic blood vessels causes ischemia, telangiectasia, damage to the blood vessel wall, resulting in difficulty in pancreatic juice excretion; Stones can block the pancreatic ducts, causing pancreatitis.
2.Chronic pancreatitis.
A disease of chronic progressive destruction of the pancreas caused by the recurrence of acute pancreatitis.

Anonymous users2024-02-10This actually says what are the best studies of pancreatitis? The most common in China is biliary pancreatitis. Biliary pancreatitis mainly includes gallbladder stones, as well as stones of the common bile duct, which fall from the gallbladder to the bile duct, and then cause the secretion disorder of the pancreatic duct, which will cause or induce acute pancreatitis, which is the most common in China.
In addition, with some changes in modern people's lifestyles, alcoholic and hyperlipidemic pancreatitis is gradually becoming more common.
What foods are good to eat for pancreatitis?

Hello, consider pancreatitis, because your pain begins after a meal, in line with the first indication of angina, pancreatitis and gastric ulcer (pain after a meal and then gradually relieved), but given your age, eighteen years old, the chance of suffering from angina is not very high, and the nature of the pain (in a zigzag) is similar to the nature of pancreatitis pain (pancreatitis: the pain is wide and radiates to the lower back in a band), so the general situation does not meet the pain characteristics of gastric ulcers, and then analyze the effect of your behavior on the pain, When you laugh, your lungs swell, the diaphragm moves down, compressing the pancreas, and when you bend over, the abdominal space will also become smaller, and the pancreas will also be compressed, so the pancreas that is inflamed and edema will naturally produce painful sensations, in addition, pancreatitis will also have symptoms such as abdominal distention, nausea and vomiting, tenderness, fever, jaundice and other symptoms (not necessarily just statistical clinical data and then summarize), if it lasts for a long time and is found to be chronic pancreatitis, there will also be abdominal pain, weight loss, diabetes and steatorrhea quadrangle, so the above reasoning is synthesizedIt is recommended that you go to a regular hospital for a systematic examination, because if the disease turns into acute pancreatitis, it will become the most difficult surgical acute abdomen, and the consequences are very serious! Please cherish your health. >>>More
Eat small, frequent meals, a high-protein, high-vitamin, low-fat diet. In the early stage, you should pay attention to dieting (note that it is best not to smoke), eating and smoking affect the activity of the pancreas, and you can eat porridge if you don't have pain in the middle and late stages, and you can eat low-fat and high-protein foods when the stomach is active first. >>>More

Many people say that they are not familiar with pancreatitis, in fact, pancreatitis is still quite high, and there are many reasons for pancreatitis, such as overeating and drinking and suffering from gallstones, etc., the symptoms of pancreatitis are mild and severe, and the mild ones are only abdominal painIf it is severe pancreatitis, it can cause extremely severe abdominal pain and may even cause shock and life-threatening。The pancreas is a digestive gland, and pancreatitis is a digestive system disease, so the causes and symptoms are closely related to the digestive system. >>>More
