Will atrophic gastritis and esophagitis cause significant weight loss?
Patients with atrophic gastritis and esophagitis may experience weight loss, as those with atrophic gastritis can have upper abdominal pain, distension pain, and burning pain, accompanied by a feeling of bloating and belching. Severe cases can lead to anemia and weight loss. The main cause of atrophic gastritis is infection by Helicobacter pylori. Of course, immune factors and dietary habits also play significant roles in the development of atrophic gastritis. Once atrophic gastritis is definitively diagnosed, it is crucial to actively eradicate Helicobacter pylori, as well as to quit smoking and drinking, and avoid using medications and consuming foods that may damage the gastric mucosa.
What should I do if reflux esophagitis causes a fever?
Reflux esophagitis, if accompanied by fever, might indicate the possibility of an infectious disease. It is necessary to further determine whether there is an infection and its location. Complete blood count and C-reactive protein tests can be conducted. At the same time, a follow-up gastroscopy should be done to observe the condition of the esophageal lesions, and histopathological examinations might be necessary when needed. Patients with reflux esophagitis require active treatment to suppress gastric acid secretion, and can also use gastroprotective agents, such as magnesium trisilicate and sucralfate. Prokinetic drugs like mosapride and itopride are also needed for treatment. Dietary adjustments should focus on a bland diet, avoiding spicy and irritating foods.
What is the difference between Crohn's disease and irritable bowel syndrome?
The main difference between Crohn's disease and irritable bowel syndrome is that Crohn's disease is an organic disease, also known as segmental enteritis, whereas irritable bowel syndrome is a functional disorder. The primary symptoms of Crohn's disease include mucous stools and pus-blood stools, and patients may also experience chills and fever. Complications may include the formation of fistulas, leading to peritonitis in patients. Irritable bowel syndrome is a functional disorder, mainly characterized by symptoms such as abdominal pain, diarrhea, and constipation. The treatment for patients with irritable bowel syndrome primarily involves the use of medications to regulate the intestinal flora and to modulate the intestinal nerves.
Do you need to fast and hold your urine for a gallbladder inflammation B-ultrasound?
When undergoing an ultrasound for cholecystitis, fasting is required, but there is no need to hold urine. However, if the examination involves the adnexa of the uterus, bladder, prostate, and other areas, it requires holding urine to perform the test, allowing the prostate, adnexa, etc., to sufficiently distend. This helps in more clearly observing pathological changes. Patients with cholecystitis need to fast before an ultrasound. If food is consumed before the scan, the gallbladder contracts more quickly, making it difficult to accurately identify lesions. Patients with cholecystitis may experience chills, fever, right upper abdominal pain, jaundice, yellowing skin, dark urine, etc. In severe cases, patients may develop septic shock and require active treatment measures.
Is atrophic gastritis negative a problem?
Atrophic gastritis negative generally means there's no major issue. A negative result for atrophic gastritis indicates that the patient is unlikely to have atrophic gastritis. In such cases, it may be considered that there is chronic superficial gastritis. If the patient has symptoms such as acid reflux, belching, heartburn, nausea, vomiting, etc., the use of proton pump inhibitors can be considered to suppress the secretion of stomach acid, and products such as aluminum magnesium carbonate and sucralfate to protect the gastric mucosa. Treatment to promote gastric motility such as Itopride or Mosapride can also be considered. Additionally, it is necessary to conduct a Carbon-13 urea breath test or Carbon-14 urea breath test to check for Helicobacter pylori infection.
In the early stages of cirrhosis, is there abdominal bloating and stomach pain?
Early-stage cirrhosis generally does not result in abdominal distension or stomach pain, and individuals in the early stages of liver cirrhosis might not exhibit any discomfort symptoms. However, if liver function reaches an advanced stage, complications like ascites associated with cirrhosis might occur, leading to abdominal distension. There might also be the occurrence of conditions like portal vein thrombosis, which can cause stomach pain, and possibly primary peritonitis, which can induce abdominal pain in patients. It is necessary to promptly identify the cause and adopt appropriate treatment measures. For example, if the stomach pain is caused by primary peritonitis, active anti-infection treatments should be applied.
What is the reason that Helicobacter pylori treatment causes black stools?
If black stools occur during the treatment of Helicobacter pylori, it is very likely due to the medication-induced black stools caused by taking potassium citrate bismuth or bismuth pectin. However, to rule out the possibility of upper gastrointestinal bleeding, a fecal occult blood test can be conducted for a clear diagnosis. Treatment of Helicobacter pylori infection requires a two-week quadruple therapy that includes bismuth. At the same time, one should avoid overeating and focus on consuming fresh vegetables and fruits rich in vitamins and easy-to-digest foods. It is also advisable to quit smoking and drinking alcohol, and avoid drinking strong tea, coffee, etc.
Is colonic inflammatory polyp serious?
Inflammatory colon polyps are not very severe, and it is very rare for inflammatory polyps to become cancerous. However, if the inflammatory polyps are relatively large, it is necessary to undergo endoscopic treatment to remove them. After removal, pathological and tissue examinations are also needed to further confirm whether the polyps are indeed inflammatory and to rule out tumorous polyps, such as adenomatous polyps, among others. Additionally, about six months after the polyp removal surgery, a follow-up colonoscopy should be conducted to check for the recurrence of polyps. The primary causes of inflammatory colon polyps could be diseases such as ulcerative colitis or Crohn's disease.
What are the symptoms before atrophic gastritis turns cancerous?
Patients with atrophic gastritis primarily exhibit symptoms such as dull pain, bloating, and burning pain in the upper abdomen, along with belching, acid reflux, weight loss, anemia, and more. If the pain from atrophic gastritis does not follow a clear pattern and is accompanied by progressive weight loss and refractory anemia, the possibility of cancerous changes in atrophic gastritis should be considered. It is advisable to promptly complete an endoscopy to confirm the diagnosis and rule out malignancy, and, if necessary, undertake a biopsy. In terms of treatment, it is first essential to test for Helicobacter pylori infection and then use medications to protect the gastric mucosa.
Are atrophic gastritis and atrophic gastric erosion the same?
Atrophic gastritis and atrophic gastric erosion do not mean the same thing; atrophic gastric erosion refers to the presence of gastric mucosal erosion based on atrophic gastritis. When atrophic gastritis is accompanied by gastric erosion, it is crucial to actively check for Helicobacter pylori infection. If the Helicobacter pylori infection tests positive, the treatment involves a two-week quadruple therapy that includes bismuth to eradicate Helicobacter pylori, along with medications to protect the gastric mucosa, such as magnesium carbonate, sucralfate, etc., and also some digestive aids. (Please take medication under the guidance of a doctor.)
