Is functional dyspepsia hereditary?
Functional dyspepsia is not a hereditary disease and does not have a genetic component. Functional dyspepsia refers to indigestion caused by the dysfunction of the stomach and intestines without any obvious organic diseases. The main symptoms include dull pain in the upper abdomen, which can manifest as burning or bloating pain. There are also symptoms such as acid reflux, belching, heartburn, diarrhea, vomiting, and sometimes the passage of mucus stools. Generally, it does not lead to purulent or bloody stools, nor does it cause fever or severe urgency after defecation, among other symptoms.
How large does a duodenal ulcer have to be to be considered severe?
There is no specific size to determine the severity of a duodenal ulcer. However, ulcers with a diameter greater than 1.5 cm are generally considered large. In such cases, strong acid-suppressing medications are needed for treatment, along with drugs to protect the gastric mucosa. Additionally, it is necessary to test for Helicobacter pylori infection. If the infection is positive, a bismuth-containing quadruple therapy should be used for two weeks to eradicate Helicobacter pylori. The choice of specific medications, as well as their dosages and administration, should be under the guidance of a doctor.
What should I do if reflux esophagitis causes vomiting and choking?
Patients with reflux esophagitis who experience vomiting and choking is relatively rare. Once vomiting and choking occur, it is necessary for the patient to urgently lie on their side, quickly expel the contents of the stomach and mouth, and they may drink some water to keep the respiratory and digestive tracts clear. If the patient still experiences choking after these measures, it is recommended to urgently visit a hospital for treatment. The specific treatment plan will be determined by a doctor based on the situation. The main symptoms of reflux esophagitis include reflux and a burning sensation in the stomach, which are the most common and typical symptoms for patients.
Can massage therapy adjust lactose intolerance?
Lactose intolerance cannot be managed through massage, and patients with lactose intolerance still need to take appropriate treatment measures to eliminate symptoms and avoid nutritional deficiencies. For primary lactase deficiency, it is advocated to reduce lactose intake, and for congenital lactase deficiency, lifelong lactose abstention is necessary. However, for patients with secondary lactose intolerance, treatment should be based on the underlying disease. For example, if Crohn's disease has caused secondary lactose intolerance, treatment with medications like mesalamine or sulfasalazine salicylate is necessary. (Please use medications under the guidance of a doctor.)
What should I do if lactose intolerance makes me feel like vomiting?
People with lactose intolerance often feel nauseous and should avoid drinking milk. If they must drink milk, it needs to undergo special treatment first. Consuming untreated milk can lead to diarrhea in lactose-intolerant individuals, and severe cases may result in dehydration and electrolyte imbalance. Additionally, those with lactose intolerance should also check for any milk allergies or diarrhea caused by indigestion. It is essential to conduct allergen tests and, if necessary, take oral medication to regulate the digestive system.
What is the cause of ear pain in reflux esophagitis?
Patients with gastroesophageal reflux disease generally do not experience ear pain. If a patient does have ear pain, it is advised to visit an ENT (ear, nose, and throat) doctor at a hospital to determine the cause. The main symptoms of gastroesophageal reflux disease include reflux and a burning sensation in the stomach. These symptoms are the most common and typical, often occurring about an hour after a meal, and some patients may experience reflux during night sleep as well. Additional symptoms can include heartburn, nausea, chronic cough, asthma, etc. However, generally speaking, it does not cause ear pain.
Can indigestion cause chest tightness?
Indigestion generally does not cause chest tightness. The main symptoms of indigestion include upper abdominal pain, accompanied by belching, acid reflux, heartburn, nausea, vomiting, constipation, or diarrhea, among others. If a patient experiences chest tightness, along with chest pain and difficulty breathing, it is necessary to consider whether it is due to a cardiac disease or a pulmonary disease, and it is recommended to go to the hospital for a formal examination. Initially, it is important to complete an electrocardiogram and a chest radiograph, followed by cardiac auscultation and pulmonary auscultation.
Does irritable bowel syndrome cause sensitivity to cold?
Irritable bowel syndrome may cause symptoms of feeling cold. Patients with irritable bowel syndrome are greatly influenced by emotions. If a patient is overly tense or anxious, it may lead to a sensation of feeling cold, although there may be no actual drop in body temperature or external temperature. Sometimes, patients with irritable bowel syndrome may need to use anti-anxiety medications for treatment, such as fluoxetine, buspirone, etc. It is also crucial to pay close attention to dietary adjustments, avoiding spicy, irritating, and cold foods, ensuring regular meals, and consuming easily digestible foods. (The use of medications should be under the guidance of a physician.)
Which severity level of reflux esophagitis is "abcd"?
Reflux esophagitis is divided into four grades: ABCD, with grade A being the least severe and grade D being the most severe. Grade D indicates that the esophageal mucosa shows damage and fusion, involving at least 75% of the esophageal circumference. The symptoms of reflux esophagitis mainly include reflux and a burning sensation in the stomach, and some patients may also experience heartburn, nausea, vomiting, and other symptoms. Reflux esophagitis can occur during nighttime sleep in some patients and is caused by the chemical irritation of sensory nerve endings beneath the esophageal epithelium due to acidic or alkaline reflux material.
What are the symptoms of stool in colon cancer?
The stool of colon cancer generally appears as mucoid or purulent bloody stool, or there is alternation of diarrhea and constipation. The diagnosis of colon cancer mainly relies on electronic colonoscopy, and routine blood tests as well as carcinoembryonic antigen tests are also of certain reference value. Patients with colon cancer often present with symptoms like anemia and weight loss. Therefore, it is crucial for patients with colon cancer to obtain a definitive diagnosis as early as possible. In addition, early surgical treatment should be adopted. After surgery, adjunct treatments such as radiotherapy and chemotherapy should also be administered.
