What should I do if chronic gastritis flares up?
If chronic gastritis flares up, patients need not be overly anxious. Standard treatment can quickly cure chronic gastritis. Following an acute flare-up of chronic gastritis, the first step involves using medications such as magnesium carbonate, aluminum sucrose sulfate, and aluminum-magnesium suspension to protect the gastric mucosa. Then, use H2 receptor antagonists or proton pump inhibitors to suppress stomach acid secretion and increase the pH level inside the stomach. Sometimes, traditional Chinese medicine is also quite effective in treating chronic gastritis, such as Qi Stagnation Stomach Pain Granules, Wen-Wei Shu, Yang Wei Shu Capsules, and Xiang Sha Yang Wei Pills. (Please use medication under the guidance of a doctor.)
Characteristics of colitis abdominal pain
The characteristics of abdominal pain caused by colitis generally include intermittent dull pain, and sometimes colicky pain might also occur, although colicky pain is less common. Patients with colitis may experience diarrhea or constipation, or alternating episodes of both. Diagnostically, colitis is primarily identified through colonoscopy, which can reveal congested, edematous, and eroded mucosa of the colon, potential inflammation, possible ulcers, and the formation of granulomas. For treatment, medications for ulcerative colitis, such as mesalazine, can be chosen. (Please use medications under the guidance of a doctor.)
Will melena from upper gastrointestinal bleeding heal by itself?
Generally speaking, after the occurrence of black stool due to upper gastrointestinal bleeding, it is quite difficult to cure and requires active treatment measures. For example, it is necessary to perform thorough gastroscopy and under gastroscopy, endoscopic treatment can be conducted. It is also advisable to consider oral medications that inhibit gastric acid secretion and protect the gastric mucosa. Medications that inhibit gastric acid secretion include proton pump inhibitors (PPIs) such as omeprazole, lansoprazole, and pantoprazole. Alternatively, H2 receptor antagonists such as ranitidine and famotidine can be selected. In terms of efficacy, proton pump inhibitors are generally more effective and better than H2 receptor antagonists, with fewer side effects.
Can you eat fish with colitis?
Generally speaking, people with colitis can eat fish, but it is necessary to avoid fried or deep-fried fish; instead, steamed or boiled fish should be consumed, as this is beneficial for the recovery from colitis. Patients with colitis should avoid other spicy and irritating foods such as strong tea, coffee, spirits, chili peppers, and mustard, etc., and try to avoid them as much as possible. It is important to eat more fresh vegetables and fruits, avoid overly coarse foods, and eat regularly and in moderation to prevent binge eating. Meals should be small and frequent, and one should chew slowly. At the same time, active follow-up with colonoscopy is necessary.
Can I eat chocolate while treating Helicobacter pylori?
During the treatment of Helicobacter pylori infection, it is permissible to eat chocolate, but it is also advisable not to consume too much chocolate. During the treatment period, one should avoid spicy and irritating foods, abstain from alcohol, and avoid drinking strong tea, coffee, etc. It is beneficial to eat easily digestible foods and fresh vegetables and fruits rich in vitamins, such as apples, bananas, and kiwis. Since chocolate is not considered a spicy and irritating food, it is permissible to eat chocolate during the treatment of Helicobacter pylori infection. However, during this period, it is also important to avoid overeating and to chew food slowly and thoroughly.
What should I do if bile reflux gastritis recurs?
If bile reflux gastritis recurs, proactive treatment measures need to be taken. For instance, if it is caused by Helicobacter pylori infection, active treatment with triple or quadruple therapy to eradicate Helicobacter pylori is necessary. If the recurrence of bile reflux gastritis is due to stomach diseases, it is crucial to actively treat the primary disease. For example, if caused by a malignant tumor in the stomach, aggressive surgical treatments should be employed, followed by adjunctive therapies such as radiotherapy, chemotherapy, and comprehensive treatment measures including traditional Chinese medicine. If caused by peptic ulcers, it is necessary to actively inhibit gastric acid secretion and protect the gastric mucosa, among other treatments.
The difference between reflux esophagitis and esophagitis
The main difference between reflux esophagitis and esophagitis is that esophagitis has a broader range, and reflux esophagitis is just one type of esophagitis. Esophagitis can be caused by many factors, as it involves inflammation changes occurring after multiple factors have damaged the esophageal mucosa. Based on different etiological factors, it can be divided into reflux esophagitis, radiation esophagitis, infectious esophagitis, eosinophilic esophagitis, drug-induced esophagitis, and radiation esophagitis. Reflux esophagitis is the most common type of esophagitis, primarily caused by the relaxation of the lower esophageal sphincter, which leads to the reflux of stomach and duodenal contents into the esophagus causing inflammatory changes. This may be related to factors such as obesity, smoking, alcohol consumption, and a high-fat diet.
What is the most urgent measure for shock due to upper gastrointestinal bleeding?
When shock occurs due to upper gastrointestinal bleeding, the most urgent treatment measure is to quickly establish intravenous access and actively and rapidly replenish fluids and blood volume. Consideration can be given to the intravenous drip of balanced solutions, Ringer's solution or 5% glucose saline. Fluid replenishment should follow the principles of starting quickly then slowing, and using crystalloids before colloids. At the same time, after shock correction, it is crucial to perform a thorough gastroscopic examination to identify the cause and location of the bleeding, and to undertake the relevant endoscopic treatments. Additionally, patients with upper gastrointestinal bleeding need comprehensive treatment including suppressing acid secretion and protecting the gastric mucosa.
Is the abdomen hard to the touch with colitis?
Generally speaking, the abdomen does not usually harden when touched in cases of colitis. However, if the patient experiences a hardening of the abdomen, it's important to consider the possibility of malignant tumors in the colon or an intestinal obstruction. The primary symptoms of colitis are mucous stools, pus and blood in stools, or alternating episodes of diarrhea and constipation. Diagnosis of colitis is mainly through examination with a colonoscope, which can reveal colon mucosal congestion, edema, erosion, etc. For the treatment of colitis, consideration can be given to orally administering drugs that regulate the intestinal flora, such as bacillus subtilis, compound lactobacillus, and others. (The use of medications should be under the guidance of a physician.)
What is the difference between the symptoms of cholecystitis and the symptoms of cirrhosis?
The symptoms of cholecystitis differ significantly from those of cirrhosis. The symptoms of cholecystitis mainly manifest as pain in the upper right abdomen, along with chills and fever, while the symptoms of cirrhosis primarily include fatigue, poor appetite, and may also present with jaundice, abdominal distension, and swelling of the lower limbs. To determine whether a patient has cholecystitis or cirrhosis, it is recommended to visit the gastroenterology department of a standard hospital as soon as possible for a comprehensive examination. This should include abdominal imaging, liver function tests, complete blood count, among others, to further clarify the diagnosis and adopt corresponding treatment measures.
