How many times a year should Helicobacter pylori be tested?
If Helicobacter pylori tests positive, then it is necessary to undergo standardized eradication treatment. A re-examination is needed one month after cessation of the eradication treatment to confirm whether the eradication was successful or the treatment failed. If the patient tests negative for Helicobacter pylori, then there is no need for repeated testing. Therefore, the frequency of testing for Helicobacter pylori within a year needs to be analyzed based on specific circumstances, using different testing methods and frequencies according to different situations. Patients infected with Helicobacter pylori should eat light, easily digestible foods, avoid overeating, and avoid spicy and irritating foods.
Is a gastric ulcer in the pyloric region serious?
Whether gastric ulcers and duodenal bulb ulcers are severe depends on the size of the ulcers and whether there are complications. If there are complications such as perforation and bleeding, it can be very serious. Severe cases may require surgical intervention and could potentially endanger the patient's life. Patients with gastric and duodenal bulb ulcers are likely caused by Helicobacter pylori infection, though it cannot be ruled out that some may be caused by ingestion of non-steroidal anti-inflammatory drugs or steroids. Treatment varies depending on the cause. For instance, if it is caused by Helicobacter pylori infection, standardized eradication of Helicobacter pylori is necessary, along with comprehensive treatment to suppress gastric acid secretion and protect the gastric mucosa.
Is duodenal ulcer bleeding a sign of cancerous change?
Duodenal ulcer bleeding does not indicate cancerous changes. The duodenal area is relatively thin, so once a duodenal ulcer occurs, it is more likely to lead to complications such as ulcer bleeding and perforation. If vomiting blood occurs with a duodenal ulcer, it indicates that the patient with the duodenal ulcer has a bleeding complication. In terms of treatment, it is first necessary to complete an endoscopic examination, which can include endoscopic hemostasis; secondly, proton pump inhibitors should be used to suppress the secretion of stomach acid and increase the pH level in the stomach; additionally, treatments that protect the stomach lining, such as aluminum hydroxide and magnesium carbonate, should be used. (Medication should be taken under the guidance of a physician.)
Can you drink sugar water after vomiting from reflux esophagitis?
Patients with gastroesophageal reflux disease can drink sugar water after vomiting, as sugar water is not spicy or irritating. Patients should avoid spicy foods, chocolate, coffee, strong alcohol, and strong tea, and should consume low-fat foods. It's also important for patients to eat frequent small meals rather than large ones, especially during dinner, and to avoid lying down immediately after eating. They should also consistently take their prescribed medication and go for regular check-ups.
How long after being discharged with acute pancreatitis can one resume a normal diet?
After being discharged from the hospital, patients with acute pancreatitis, upon re-examination of routine blood tests and upper abdominal CT scans showing complete healing of pancreatitis, may, as appropriate, consume a low-fat, high-carbohydrate diet and gradually transition back to a normal diet. This process generally requires at least two months to be considered safe. Patients discharged after acute pancreatitis must abstain strictly from alcohol, avoid binge eating, and avoid overly greasy food. Greasy food can easily lead to increased bile discharge and potentially cause blockage of the pancreas, possibly triggering a recurrence of pancreatitis.
Can you drink water with acute pancreatitis?
During the acute attack of acute pancreatitis, it is essential to immediately prohibit eating and drinking, as it may exacerbate the condition. Once the abdominal pain disappears and the body temperature normalizes, one can gradually resume eating and drinking, starting with small amounts of water and liquid food. However, it is also necessary to avoid consumption of meats and protein-rich foods. Additionally, if eating prompts a relapse of the condition, it indicates that the prohibition of eating and drinking should continue. If patients with pancreatitis resume eating and drinking too soon, it can lead to a worsening of the condition.
Why is there nothing wrong with the B-ultrasound for cholecystitis?
As for why cholecystitis appears normal in an ultrasound, there are two possible reasons. One possibility is that the medical practitioner conducting the ultrasound may lack sufficient clinical experience to identify an inflamed gallbladder. Another reason could be limitations in the ultrasound equipment itself, which might fail to detect an inflamed gallbladder. There are very few cases where cholecystitis appears normal under ultrasound. The main ultrasound features of cholecystitis include gallbladder wall edema, roughness, and an enlarged gallbladder among other radiological changes. Once cholecystitis is diagnosed, it is crucial to undertake active treatment measures, such as aggressive anti-infection treatment, spasmodic pain relief, etc.
How to regulate digestion and weight gain for those who are underweight
People with indigestion who are relatively thin can enhance their nutrition by eating protein-rich foods such as beef, lamb, and lean meat. However, those with indigestion should not eat spicy or stimulating foods, and should avoid alcohol, strong tea, coffee, etc. It is important to rest adequately and engage in moderate physical exercise. Diet should be regular in timing and quantity, avoiding overeating or binge eating. It is advisable to consume more fresh vegetables and fruits rich in vitamins, such as apples, kiwifruits, and bananas. Patients with indigestion should not be tense or anxious and should maintain a pleasant mood.
What can be eaten during the recovery period of acute pancreatitis?
Patients with acute pancreatitis in the recovery phase should start to eat some sugary liquid diets, beginning with easily digestible sugary foods. Generally, it is recommended to transition from liquid to semi-liquid diets, and then to a normal regular diet. However, patients with acute pancreatitis in the recovery phase should still avoid overeating and consuming too greasy foods. They should also abstain from alcohol and avoid eating overly fatty foods such as meat fried noodles, fried rice with eggs, and braised pork. These foods should be largely avoided, while increasing the intake of protein-rich foods for the patient.
Does irritable bowel syndrome cause flat stools?
Generally speaking, irritable bowel syndrome does not cause flat stools. If a patient experiences flat stools, it is very likely due to a tumor or polyps in the intestine compressing the stool, leading to deformation and flatness of the stool. Once a patient experiences flat stools, it is advised to visit the gastroenterology department of a hospital as soon as possible to undergo a colonoscopy to determine the cause of the flat stools. If it is found to be caused by a tumor or polyps in the intestine, then a biopsy of the pathological tissue should be done to promptly confirm the diagnosis. Of course, it could also be caused by conditions such as anal stenosis.
