How harmful are duodenal ulcers?

It can cause epigastric pain, which can be dull, burning, bloating, or severe, or may manifest as dull discomfort only when hungry. All in all, it's maddening!

Patients with duodenal ulcers will have severe abdominal pain. It is also accompanied by symptoms such as diarrhea. In severe cases, blood may occur in the stool. and cause other complications.

Duodenum is a digestive tract organ between the stomach and jejunum, which can be divided into four parts: bulb, descending, horizontal and ascending, which can receive the injection of gastric juice, pancreatic juice and bile, and has a strong physiological function of digestion and absorption of nutrients, the duodenum is located in the right upper abdomen, with a total length of about 25-30cm, and common diseases include duodenal ulcer, erosion, etc. In life, we should pay attention to protecting the gastrointestinal tract, and you can eat honey, jujubes, eggs, yogurt, etc. to play a preventive and protective role.

The duodenum is close to the middle of the stomach and jejunum, and the adult duodenum is 20 cm long, and the tube is meridian.

4 5 cm, close to the posterior abdominal wall, is the shortest length of the colon, the meridian is larger, the part is deep and more fixed. The pancreatic duct and gallbladder open in the duodenum. Therefore, it accepts both gastric acid and the introduction of pancreatic juice and bile, so the digestion and absorption of the duodenum is very important.

Possible causes of duodenal pathogenesis: the erosive effect of gastric juice and pepsin and the influencing factors: the erosive effect of gastric juice and pepsin, especially the effect of gastric acid, plays a key role in the production of ulcers.

Weakening mucosa maintenance elements: mucus-mucosa code the destruction of the natural barrierUnder normal conditions, the gastric mucosa is covered by the mucus metabolized by its epithelial cells, and the mucus is connected with the detailed epithelial cytoplasmic protein layer and somatic cells to produce a defense, which is called the mucus-mucosal natural barrier.

Genetic factors are the main position, and genetic factors are mainly reflected in family history, and often manifest as bloody and abnormal blood secretions. In addition, the incidence of duodenum is more than twice as high as that of the general population, and the weakening of the defense mechanism of the duodenal mucosa is also a cause of duodenal ulcer, which retards the emptying of the gastric tract through specific pH, sensitive receptors, acidification reactions, and feedback, keeping the duodenal pH close to neutral.

If the defense mechanism of the duodenal mucosa is disrupted, then it may cause damage to the duodenal mucosa and the formation of ulcers.

In addition, excessive gastric acid secretion may lead to damage to the duodenal mucosa, resulting in ulcers, in addition, Helicobacter pylori infection is closely related to the occurrence of duodenal ulcers, the formation of duodenal ulcers is also closely related to lifestyle habits and environment, regular use of analgesics, smoking, stress reactions, may cause duodenal ulcers.

Duodenal ulcer is a common type of peptic ulcer, it is a common disease in life, and the incidence of men is significantly higher than that of women, and there are more and more people suffering from duodenal ulcers, so what causes duodenal ulcers?

1. Poor eating habits.

The stomach is a very important part of the human digestive system, and it is also a place where it is easy to get infected and sick, poor eating habits, irregular diet, overeating, alcoholism, especially alternating hot and cold diet, etc., may induce the occurrence of gastric ulcers, and the incidence of duodenal ulcers in long-term smokers is significantly higher than that of non-smokers.

2. Genetic factors.

Genetic factors play an important role in the susceptibility of this disease, and the incidence of familial incidence in patients is twice higher than that of the general population.

3. Excessive gastric acid secretion.

Gastric acid is a decisive factor in the development of duodenal ulcers.

4. The defense mechanism of the duodenal mucosa is weakened.

If the patient's gastric emptying is accelerated and the effect of gastric acid suppression is reduced, the acid load in the duodenal bulb lumen increases, resulting in mucosal damage and duodenal ulcer.

5. Helicobacter pylori infection.

Helicobacter pylori infection is closely related to the pathogenesis of peptic ulcer, and HP infection is the main cause of gastritis and an important factor causing peptic ulcer.

Dangers of duodenal ulcers.

1. Duodenal ulcer will cause ulcer bleeding if it is not timely, the so-called ulcer bleeding refers to a bleeding volume of more than 60 100 ml with obvious digestive symptoms, the main manifestations are dizziness, pulse rate, paleness, cold sweat and cold limbs, blood pressure drop and other signs of shock, if the bleeding is too fast, it will even be life-threatening.

2. Acute perforation of ulcer is the most serious complication of ulcer disease, accounting for about 15% of ulcer disease, and it is also the main cause of death from ulcer disease.

3. Duodenal ulcer may cause ulcer cancer, gastric ulcer cancer is more common in older patients with a history of chronic ulcer, accounting for about 2% to 5% of ulcer disease, young people also occasionally have cancer, duodenal ulcer malignant transformation chance is less.

What causes duodenal ulcers? Hopefully, the above introduction will be helpful to you.
