The difference between esophagitis and esophageal cancer.
Esophagitis and esophageal cancer have essential differences. Esophagitis is merely an inflammatory disease, which is relatively common in clinical settings and often related to excessive stomach acid, acid reflux, or other physical and chemical irritants. Esophageal cancer, on the other hand, is a malignant tumor. The mechanisms of their development, as well as the differences in prognosis and treatment plans, are very significant.
Do you have a fever with gastroenteritis?
Gastroenteritis mainly presents symptoms of abdominal pain and diarrhea, with an increased frequency of bowel movements, ten times or even more than ten times, accompanied by nausea, vomiting, and decreased appetite. There may be irregular fevers, such as low-grade fever, and severe cases can develop high fever. Subsequently, the symptoms of the patient become more severe, manifesting restlessness and lethargy, even confusion or coma. Therefore, we must pay special attention and not take it lightly.
Can esophagitis be cured?
Common causes of esophagitis include reflux of stomach acid and inflammation caused by excess stomach acid. Esophagitis can be healed through dietary control and medical treatment. However, it is prone to recurrence, for example, with increased stomach acid, worsening of chronic gastritis or acid reflux, and lack of attention to diet, among other factors. Therefore, we advise patients to avoid irritating foods and appropriately consume medications that protect the mucosa and suppress stomach acid.
Diagnosis methods for chronic gastritis
Chronic gastritis symptoms are relatively common, often including abdominal pain and bloating. Patients with abdominal pain and bloating often present these symptoms. To rule out gastrointestinal tumors, ulcers, and other diseases, we need to go through some short-term medical treatments. If the symptoms do not improve, we need to consider the possibility of gastric ulcers or gastric tumors. Of course, the fundamental diagnostic method is still through gastroscopy, to definitively diagnose chronic gastritis. If necessary, a pathological examination should be conducted for confirmation.
How to alleviate gastroenteritis?
If the patient has gastroenteritis, we recommend that the patient should rest in bed as much as possible. For patients with mild conditions, we can advise oral intake of glucose and electrolytes to replenish the loss of body fluids. If there is persistent vomiting or evident dehydration, intravenous rehydration with glucose saline and other relevant electrolytes is necessary. We encourage the intake of light liquid or semi-liquid diet to prevent or treat mild dehydration. Additionally, injections of pain relievers, antispasmodic drugs, and antidiarrheal medications can be administered for symptomatic treatment. For infectious diarrhea, targeted antibiotics can be used, but it is advised to avoid their misuse.
What is acute gastroenteritis?
Acute gastroenteritis often has a history of consuming unclean food, with an incubation period that usually ranges from several hours to several days, most commonly one to two days. The onset of acute gastroenteritis is typically characterized by abdominal pain, diarrhea, urgent and increased bowel movements, nausea, vomiting, fever, and even convulsions. The frequency of bowel movements may increase to 10-30 times a day, and the patient may experience mild fever among other symptoms. Severe diarrhea can be accompanied by stools containing pus and blood, along with vomiting. In severe cases, patients may also experience dehydration and even shock. Therefore, patients with acute gastroenteritis should try to replenish energy, avoid exacerbation of the illness due to electrolyte imbalance, and prevent severe dehydration.
What should someone with chronic gastritis eat normally?
For patients with chronic gastritis, we recommend avoiding irritant foods and opting for foods that cause less irritation to the stomach. Avoid overly acidic or sweet foods. It is suggested that patients keep foods like steamed buns and soda crackers, which are alkaline, on hand. Try to avoid consumption of raw, cold, hard, or hot foods, as well as tea, coffee, and substances like tobacco and alcohol, which are highly irritating to the stomach.
Do you need an IV for a stomach flu?
When suffering from a stomach flu, symptoms often include abdominal pain, diarrhea, and bloating. If the symptoms are mild, it is recommended that patients take some antispasmodic and pain relief medications orally. In terms of diet, it is best to avoid irritant foods and consume oral rehydration salts to prevent electrolyte imbalance and significant fluid loss. If the patient experiences severe diarrhea, it is advisable to appropriately supplement with sugar and electrolyte solutions or liquids. If the condition worsens, the use of antibiotics and antiviral medications may be considered.
How is esophagitis treated?
Esophagitis is clinically common due to acid reflux and various physical and chemical irritants that cause inflammation. Therefore, we often recommend treatments that suppress stomach acid and protect the gastric mucosa. Additionally, if there are physical and chemical irritants, patients should avoid using or accidentally consuming certain medications, foods, or other chemicals that could cause esophagitis.
How to alleviate gastroenteritis pain
Gastritis pain often falls into the category of spasmodic pain. We can provide patients with appropriate gastrointestinal antispasmodics, such as Atropine tablets, which can have a symptomatic effect. Additionally, we advise patients to avoid using painkillers, as common analgesics may mask the symptoms. Therefore, we only provide symptomatic treatment for spasms. If the symptoms do not improve and the pain intensifies, we still recommend that patients undergo further examinations to rule out conditions such as gastrointestinal obstruction or other complications like perforations.
