Can peptic ulcers become cancerous?
Peptic ulcers generally refer to gastric ulcers and duodenal ulcers. It is generally believed that most gastric ulcers are benign, but a small portion of patients may develop cancer, approximately 3%-5%, especially in middle-aged and elderly patients. If the ulcers recur and continue to enlarge, there needs to be vigilance for potential malignancy. However, duodenal ulcers generally do not become cancerous and are more common in young people, presenting symptoms such as abdominal pain, bloating, and bloody stools. Therefore, for peptic ulcers, most are benign, but a small fraction of patients may have ulcers that evolve into cancerous ones, presenting as benign peptic ulcers, which calls for caution, especially in middle-aged and elderly patients. Therefore, it is recommended that patients regularly treat gastric and duodenal ulcers. If the treatment period is prolonged and peptic ulcers recur frequently with poor outcomes, patients should be alert to the potential for cancer and are advised to undergo gastroscopic examination and biopsy for further clarification.
Can colitis turn into cancer?
Colitis is considered a benign lesion clinically and generally does not transform into cancer. Therefore, patients do not need to worry too much. The diagnosis of colitis mainly relies on colonoscopy. Most patients undergo colonoscopy due to abdominal discomfort or abnormal stools. The abdominal discomfort is primarily in the lower abdomen or lower left abdomen, presenting as pain and distension. Abnormal stools can clinically manifest as changes in the frequency of bowel movements, changes in stool texture to harder or thinner, and so on. Most patients do not exhibit alarming symptoms such as bloody stools, weight loss, or decreased appetite. Colonoscopy is frequently used clinically and can generally serve to differentiate between colitis and colon cancer. Most patients can tolerate a colonoscopy, so there is no need for patients to resist undergoing this examination.
Causes of Pancreatitis
Common causes of pancreatitis in clinical settings include biliary tract diseases, alcohol consumption, overeating, and hyperlipidemia, among others, with biliary tract diseases being the most common. Pancreatitis is generally defined as inflammatory changes in the pancreas due to self-digestion caused by various reasons. Clinical manifestations include abdominal pain, bloating, nausea, and vomiting, etc. Therefore, for patients with upper abdominal pain, it is necessary to further complete some examinations, such as liver function, amylase, lipase, abdominal ultrasound, and even abdominal CT scans, to clarify the diagnosis, which is generally straightforward for pancreatitis. The treatment of pancreatitis, in addition to symptomatic treatment, requires etiological treatment, combining different causes of pancreatitis. For instance, if caused by hyperlipidemia, lipid-lowering treatment is generally needed; if biliary tract disease is considered, active treatment of the biliary disease is required.
Can I eat watermelon with atrophic gastritis?
Patients with atrophic gastritis can certainly eat watermelon, as long as it is consumed in small amounts. The diet for atrophic gastritis should primarily consist of easily digestible, clean foods, and avoid spicy and irritating foods, such as salted fish and alcohol intake, etc. Typically, patients with atrophic gastritis seek medical advice due to abdominal discomfort, exhibiting symptoms such as abdominal pain, bloating, nausea, vomiting, and early satiety. A comprehensive gastroscopy indicates inflammatory changes and atrophic alterations of the gastric mucosa. In terms of treatment, apart from dietary management, pharmacological treatment can be selected, including acid-reducing and gastric-protective medications, particularly suitable are traditional Chinese medicines that protect the stomach. It is advisable to supplement some vitamins and avoid spicy and pickled foods. Certainly, for atrophic gastritis, it is important to be cautious of concurrent Helicobacter pylori infection. If Helicobacter pylori infection is considered, anti-Helicobacter pylori treatment is recommended for the patient, followed by regular follow-ups, typically every six months to one year for a gastroscopy examination. (Medication should be used under the guidance of a doctor.)
Symptoms and Treatment of Bile Reflux Gastritis
The symptoms of bile reflux gastritis generally include abdominal pain, bloating, and nausea, among others, and are relatively common in clinical settings. Typically, the main manifestations are hidden abdominal pain, bloating pain, or even burning pain, which occur repeatedly over time. This condition is often seen in clinical practice and tends to have a prolonged course, generally not accompanied by fever or radiating pain in the lower back or right shoulder blade. A thorough gastroscopic examination in patients will clearly show congested and edematous mucosa in the stomach, and the mucus appears bile-stained, indicating that the inflammation of the stomach is likely caused by bile reflux. For treatment, attention should be paid to diet and medication. The dietary approach involves consuming easily digestible, bland food; medically, the use of acid-reducing and gastroprotective agents, as well as anti-bile reflux medications are recommended. Typically, a treatment course of about two weeks is sufficient for gaining substantial control of the condition. If the patient has other concomitant issues, proactive treatment is advised.
Are there many people with gastric polyps?
Gastric polyps are relatively common in clinical settings and have a higher incidence, so patients should not feel overly burdened psychologically. Clinically, gastric polyps are often identified when patients seek medical help for abdominal discomfort and undergo gastroscopy. The main symptoms include discomfort in the upper abdomen, such as bloating, abdominal pain, nausea, and belching. Gastric polyps are generally considered benign lesions, and regular follow-up examinations are usually sufficient. During these follow-ups, if it is found that the polyps have increased in number or size, especially if they are larger than one centimeter, they can then be removed through endoscopic surgery. Most patients can tolerate this well and it is considered a safe and effective method for diagnosis and treatment, so patients should not be overly concerned or overthink the situation. The occurrence of gastric polyps is increasingly observed clinically, primarily through gastroscopy, and it is recommended to undergo a gastroscopy every six months to a year for follow-up.
How often should gastric polyps be rechecked?
Patients with gastric polyps are generally advised to have a gastroscope re-examination every six months to a year. If the polyp does not grow during the swelling process, and remains roughly the same, we recommend continuing with follow-up. Of course, if the polyps increase in number or size, especially if larger than one centimeter, we recommend timely endoscopic removal. Gastric polyps are actually a common condition clinically, and patients generally do not have any specific symptoms. Most patients discover the polyps incidentally during a gastroscopy. Most gastric polyps we find are benign, but a small proportion of patients may progress to cancer over time. Therefore, patients with gastric polyps do not need to be overly concerned, just undergo regular gastroscopic re-examinations, and perform gastroscopic removal when necessary. The exact cause of gastric polyp formation is not clear, and patients may undergo further tests, such as screening for Helicobacter pylori. If Helicobacter pylori infection is detected, we recommend treatment for Helicobacter pylori.
Is APC treatment for gastric polyps painful?
The treatment of gastric polyps is mainly focused on endoscopic procedures, including APC (argon plasma coagulation) treatment, which is quite suitable for gastric polyps. For patients, the APC treatment usually does not involve pain, so there is no sensation or suffering involved. Thus, APC treatment for gastric polyps is relatively appropriate and generally considered safe. The complications to be cautious of are not pain, but rather bleeding, such as gastrointestinal bleeding post-procedure. For gastric polyps, APC treatment may take varying lengths of time; it might be completed in just a few minutes under smooth conditions, but could extend to over ten minutes in some cases. Overall, this is a relatively mature and safe examination method.
Does bile reflux gastritis cause stomach pain?
Bile reflux gastritis can cause stomach pain, often presenting as pain in the upper abdomen, typically as dull or distending pain which are most commonly seen in clinics. Bile reflux gastritis is generally considered a common disease, characterized by symptoms such as abdominal pain, bloating, and nausea at onset. Diagnosis largely relies on gastroscopy, during which we can observe inflammatory changes in the gastric mucosa, with the mucosa appearing congested and swollen, and the gastric mucus appearing yellow, generally considered to be caused by bile reflux. The treatment for bile reflux gastritis typically consists of dietary adjustments and medications. Dietary recommendations include regular, bland meals, and avoiding intake of coffee, alcohol, and spicy or irritating foods. Medications may include acid reducers, gastroprotective agents, and anti-reflux drugs. A typical course of treatment lasts from 7 to 14 days. Of course, if a patient has severe symptoms or recurrent episodes, a minimal maintenance dose may be used to relieve symptoms. (Note: Medication should be taken under the guidance of a professional doctor.)
Can stomach polyps be felt by touch?
Gastric polyps are relatively common in gastroenterology and are generally asymptomatic. However, if the polyps are relatively large or numerous, symptoms such as early satiety, abdominal distension, and nausea may occur. Gastric polyps cannot be detected through physical examination, which generally yields negative results. There may be some abdominal tenderness, but gastric polyps cannot be detected through physical examination. The diagnosis of gastric polyps primarily relies on completing a gastroscopic examination, which can provide reference values for the size, scope, and quantity of the polyps. Therefore, gastric polyps cannot be detected by physical examination, and it is recommended to complete a gastroscopic examination for further clarification. Thus, as mentioned above, gastric polyps cannot be detected by physical examination; a comprehensive gastroscopic examination is recommended.
