How to treat acute gastroenteritis?
Acute gastroenteritis is quite urgent and is characterized by significant nausea, vomiting, and diarrhea. The treatment principle involves bed rest and symptomatic use of antiemetic, antispasmodic, antidiarrheal, and rehydrating medications. For milder cases, oral rehydration solutions can be consumed. If persistent vomiting occurs with obvious dehydration, it is timely to administer intravenous fluids to replenish relevant electrolytes, and, if necessary, inject drugs for antispasmodic and antiemetic purposes; For infectious diarrhea, sensitive antibiotics can be chosen. During treatment, it is important to drink water properly, eat vegetables, stay hydrated, eat smaller and more frequent meals, and avoid spicy and greasy foods.
Causes of appendicitis
The main causes of appendicitis are the narrowing of the appendix lumen and the subsequent blockage of the appendix lumen. Bacterial infection can directly cause acute inflammation. Additionally, poor dietary habits in daily life can also trigger appendicitis. These include overeating and binge drinking, engaging in strenuous exercise right after eating, consuming strong tea, coffee, or spirits, neglecting rest, and excessive fatigue. Therefore, for the prevention of appendicitis, it is mainly important to develop regular lifestyle and eating habits, with meals at fixed times and in measured amounts, and consuming more vegetables to ensure the smooth functioning of the gastrointestinal tract.
How to reduce fever in acute gastroenteritis
Acute gastroenteritis generally manifests as fever, abdominal pain, and diarrhea. If the fever does not exceed 38.5°C, antipyretic medications can be used, along with physical cooling methods such as wiping the patient's forehead, palms, and soles with a warm towel to facilitate heat dissipation through evaporation. If the fever exceeds 38.5°C, muscular injection of antipyretic drugs should be chosen, along with combined infusion therapy to prevent signs of physical collapse caused by high temperatures. At the same time, active use of antibiotics and antidiarrheal medications is advised. During treatment, a regular diet should be maintained, adopting the principle of eating small and frequent meals. Rest is important, and excessive fatigue should be avoided. (The use of medications should be under the guidance of a doctor.)
Is appendicitis prone to recurrence?
For acute appendicitis, if the appendix is not removed surgically, it is relatively prone to recurrence, and chronic appendicitis may also develop. Therefore, once appendicitis is diagnosed, surgery to remove the appendix is generally required. The more commonly used surgical method is laparoscopic appendectomy. This method involves less bleeding during the surgery and quicker postoperative recovery, with minimal damage to the body. Only small scars can be seen on the body surface, making it a preferable option for those concerned about aesthetics.
Manifestations of chronic gastroenteritis
Chronic gastroenteritis primarily manifests as chronic inflammation of the stomach and intestines, which can include chronic abdominal pain, diarrhea, and decreased appetite. Due to poor appetite and impaired digestive absorption, symptoms such as physical emaciation, fatigue, and lethargy can occur, making one more susceptible to catching colds. For chronic gastroenteritis, it is important to adjust the imbalance of gut flora and use antibiotics to control infections. Attention should be paid to a light, regular diet, eating three meals at fixed times and amounts, avoiding greasy and spicy foods, and consuming more light vegetables and fruits. (Please use medications under the guidance of a doctor)
Characteristics of vomiting in acute gastritis
Acute gastritis is characterized by severe nausea and vomiting, usually of stomach contents, and sometimes includes bile. It is also accompanied by significant abdominal pain. In such cases, it is imperative to administer antispasmodic analgesics and antiemetic medications promptly, as well as antibiotics sensitive to the gastrointestinal tract. If the vomiting is severe, it may lead to dehydration, necessitating timely rehydration or intravenous fluid therapy. It is important to maintain dietary hygiene, consume soft, easily digestible foods, and reduce the intake of raw, cold, and spicy foods. Meat should be thoroughly cooked before consumption. Engaging in moderate outdoor physical activities after meals can enhance gastrointestinal motility. (Please use medications under the guidance of a doctor.)
Is chronic gastritis easy to treat?
The treatment of chronic gastritis primarily aims to alleviate symptoms and reduce the recurrence of the disease; it is generally difficult to cure completely. The medications chosen are mainly for protecting the gastric mucosa and inhibiting gastric acid secretion. If there is an infection with Helicobacter pylori, it should be completely eradicated. Additionally, attention should be paid to dietary adjustments, consuming soft and easily digestible foods, and avoiding spicy, stimulating, and greasy foods. It is important to engage in appropriate outdoor exercise, develop good living habits, and regulate emotions, as excessive tension, irritability, and anger can exacerbate chronic gastritis.
Postoperative diet for acute appendicitis
Postoperative diet for acute appendicitis should be taken with special attention. On the day of the surgery, no food should be consumed. After waiting for anal gas to pass, which typically occurs on the first day post-surgery, a semi-liquid diet can be chosen, consisting of easily digestible foods such as rice porridge, millet congee, and vegetable soup. From the third to the fifth day post-surgery, a normal diet can be resumed, including eating eggs and meat to supplement proteins and dietary fibers, which help the incision heal. Vegetables and fruits should also be consumed to prevent constipation. Additionally, proper care should be taken of the incision site, including regular dressing changes.
Can people with Crohn's disease drink yogurt?
Patients with Crohn's disease can drink milk. Crohn's disease is an inflammatory lesion that occurs in the intestines, where the absorption and digestion functions are impaired. Drinking some yogurt appropriately can help the intestinal absorption function and assist in digestion. Due to the impaired absorption function of the intestines, symptoms such as fever and lowered immune function may occur. At this time, patients need to enhance their nutrition. The dietary principle should focus on eating smaller, more frequent meals that are high in nutrition and low in fat, such as lean meats, egg products, meat products, milk, and fish. It is also important to consume more vegetables to supplement vitamins, such as Chinese yam, carrots, and fresh green vegetables, and to ensure plenty of rest.
How long does it take for a stomach ulcer to heal?
Gastric ulcers are a very common disease in gastroenterology. For minor ulcers, adjustments in diet, quitting smoking and drinking, consuming more green vegetables, getting more rest, and reducing mental stress can gradually lead to recovery. More severe ulcers require active medication use. To achieve ulcer healing, the course of acid-reducing medication usually lasts four to six weeks. Commonly used medications include those that inhibit gastric acid secretion, such as HR receptor antagonists and proton pump inhibitors, as well as some bismuth agents and weakly alkaline antacids to protect the stomach lining. Meanwhile, dietary management should be strengthened. Through effective medical treatment, the healing rate of gastric ulcers can reach over 95%. (Specific medication use should be conducted under the guidance of a doctor.)
