Can you drink water with acute pancreatitis?
Patients with acute pancreatitis cannot drink water or eat anything during the acute phase. They must undergo gastrointestinal decompression to suction out gastric juice, gastric acid, and gastric contents. At the same time, treatment for acute pancreatitis includes inhibiting pancreatic secretion, anti-infection measures, intravenous fluid replenishment, and maintaining electrolyte balance, among others. If a patient with acute pancreatitis experiences bowel movements, gas, relief from abdominal pain, and a decrease in blood amylase to normal levels, they may then consider drinking small amounts of water and consuming light foods like rice soup or thin porridge. If the abdominal pain disappears, the patient can gradually increase their water intake.
What should I do if I vomit due to lactose intolerance?
Lactose intolerance can lead to vomiting, which can be managed based on the condition by symptomatic treatment. For example, Metoclopramide can be used orally or through muscle injection to alleviate vomiting. If necessary, chlorpromazine injections can also be used for treatment. The choice of specific medications and their administration must adhere to medical advice. In addition to addressing the symptoms, it is essential to treat the primary disease causing lactose intolerance. For instance, if it is caused by ulcerative colitis, then treatment should focus on this condition. In the case of primary lactose intolerance, a lifelong avoidance of lactose-containing foods is necessary. (Medication use should be under the guidance of a physician.)
How many days of fasting for acute pancreatitis?
The duration for which patients with acute pancreatitis must fast is determined by the severity of their condition. Some may only need to fast for a day or two, while others may require around three to four days, or even a week. In severe cases of acute pancreatitis, it might be difficult to say how long the fasting could last, potentially around two weeks. Once patients with pancreatitis start eating after a series of active treatments such as anti-infection measures, inhibiting pancreatic secretion, replenishing electrolytes, and balancing acid-base levels, and following treatments like using rhubarb to facilitate bowel movements, if their bowel movements and gas expulsion have mostly returned to normal and amylase levels have largely normalized, they can cautiously start consuming low-fat, high-vitamin, and high-calorie liquid foods.
How long does Helicobacter pylori resistance last?
Helicobacter pylori resistance generally develops around two weeks. If Helicobacter pylori shows resistance, it is advisable to consider adjusting the treatment using other antibiotics. The eradication treatment for Helicobacter pylori infection generally involves a two-week quadruple therapy with a bismuth-containing regimen. Furthermore, one month after stopping the eradication treatment, it is necessary to recheck with a carbon-13 breath test or a carbon-14 breath test to confirm effective eradication. Helicobacter pylori infection can cause gastritis, peptic ulcers, and malignant tumors in the stomach, among other issues.
Can gastroesophageal reflux esophagitis be detected by a CT scan?
Reflux esophagitis generally cannot be detected on a CT scan unless it is very severe, at which point it may be evident on a CT. Diagnosis of reflux esophagitis is primarily through gastroscope examination, where damage and erosion of the esophageal mucosa can be observed. Patients with severe reflux esophagitis may experience symptoms such as acid reflux, heartburn, and a burning sensation behind the sternum. Additional diagnostic methods include upper gastrointestinal barium meal imaging and tissue pathology biopsy. An electrocardiogram can also be performed to rule out the possibility of conditions such as angina.
Does acute pancreatitis cause abdominal muscle tension?
If a patient with acute pancreatitis shows symptoms of peritonitis, abdominal muscle rigidity may occur. Acute pancreatitis is divided into acute edematous pancreatitis and acute hemorrhagic necrotizing pancreatitis. The main symptoms of acute edematous pancreatitis include abdominal pain, nausea, vomiting, and fever. If it is hemorrhagic necrotizing pancreatitis, it can lead to shock, respiratory distress syndrome, high fever, jaundice, abdominal distension, and the abdominal compartment syndrome in the patient. Severe cases can cause intestinal paralysis and signs of peritoneal irritation, leading to abdominal muscle rigidity and also possibly presenting with shifting dullness, among other symptoms.
What kind of milk should adults with lactose intolerance drink?
If an adult is lactose intolerant and allergic to drinking milk, they must drink milk that has undergone some special treatment. If it is not specially treated, drinking it can easily cause diarrhea. Diarrhea from drinking milk may also be due to an allergy to a component of the milk. If that is the case, it is necessary to improve allergen detection and try to avoid drinking milk. If diarrhea is caused by poor digestion in the gastrointestinal tract, some medications that regulate intestinal flora can be used for supportive treatment.
Characteristics of vomiting in duodenal ulcer
The main characteristic of vomiting due to duodenal ulcer is postprandial vomiting. Generally, patients with duodenal ulcers are prone to pyloric obstruction. When a large meal is consumed, pyloric obstruction may occur, preventing stomach contents from passing into the duodenum, leading to vomiting. Additionally, patients might also experience vomiting of acidic stomach contents while fasting. After vomiting, patients with duodenal ulcers can use acid-suppressing medications to alleviate gastric edema and medications like mosapride to promote gastric motility. (Medication should be used under the guidance of a physician.)
How many times a day does lactose intolerance cause diarrhea?
Patients with lactose intolerance can have multiple bowel movements per day after consuming milk; a mild case can result in 3-4 bowel movements, while severe cases might lead to dozens, potentially causing dehydration and electrolyte imbalance. For lactose-intolerant patients who need to consume milk, it must be specially treated beforehand. Additionally, if diarrhea is caused by poor digestion in the gastrointestinal tract, certain medications that adjust the gut microbiota can be used to aid digestion, such as Bifidobacterium triple viable bacteria and Bacillus cereus, etc. If the diarrhea is caused by allergies, allergen testing should be conducted. (Please use medication under the guidance of a doctor.)
Is hot compress effective for duodenal ulcer?
Patients with duodenal ulcers may achieve some effects through hot compresses, but hot compresses cannot truly effectively treat duodenal ulcers. To effectively treat duodenal ulcers, it is first necessary to detect the presence of Helicobacter pylori infection through the carbon-13 breath test or carbon-14 breath test. If the Helicobacter pylori infection is positive, it is necessary to eradicate Helicobacter pylori using a quadruple therapy containing bismuth. Subsequently, it is important to use proton pump inhibitors or H2 receptor antagonists to inhibit gastric acid secretion, and medications like aluminum magnesium carbonate to protect the gastric mucosa. (The use of medications should be under the guidance of a physician.)
