Can acute pancreatitis patients have sexual intercourse?
Patients with acute pancreatitis cannot have sexual intercourse during the acute treatment period because it can lead to physical exhaustion and further weaken the patient's condition. Therefore, during the acute phase of acute pancreatitis, the focus should be on rest, and the diet should include foods rich in vitamins and carbohydrates, such as starchy foods, fresh vegetables, and fruits. It is important to avoid overeating, greasy foods, and alcohol consumption. If patients with acute pancreatitis recover fully, and their physical strength is completely restored, they may then consider resuming sexual activity.
Is dry, pellet-like stool a symptom of colon cancer?
Dry, granular stools are not necessarily symptoms of colon cancer, but patients with colon cancer may also experience dry, granular stools. Therefore, after exhibiting the above symptoms, patients need to promptly complete an electronic colonoscopy to confirm the diagnosis of the disease. For example, if the symptoms are due to colon cancer, aggressive surgical treatment should be taken, followed by comprehensive treatment including radiotherapy and chemotherapy. If the symptoms are due to functional indigestion causing constipation, treatment should involve using medications to regulate the intestinal flora and relieve constipation.
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.)
