During the change of seasons and temperature changes, the number of patients with gastrointestinal colds increases, but since both gastroenteritis and gastrointestinal colds have symptoms such as diarrhea, loss of appetite, nausea and vomiting, most patients with gastrointestinal colds have a rapid onset, with gastrointestinal symptoms first, followed by cold symptoms, and often self-diagnose themselves as having gastroenteritis first in the early stages. With gastroenteritis there can be stomach cramps, diarrhea, fever and nausea, and there may also be vomiting and fever. It is very uncomfortable for the first day or two, but then it gets better. There is no vaccine or specific treatment for gastroenteritis. When you have gastroenteritis, you need to rest until you feel better. When you vomit, do not eat solid food, but eat fluids such as water or oral rehydration salts. This will prevent dehydration caused by diarrhea or vomiting. Once the vomiting stops, you can start trying other kinds of fluids such as soups and juices. After symptoms improve further, try lighter foods such as toast, pretzels or crackers, rice and noodles. As digestive function returns to normal, you can gradually transition to a normal diet. I. What are the symptoms of gastrointestinal cold The gastrointestinal cold is dominated by gastrointestinal symptoms, such as diarrhea, bloating, abdominal pain, vomiting, etc., while cough, fever and other cold symptoms are relatively rare. 1.Vomiting: The stomach is stimulated by the entry of vector bacteria or other toxic substances, which leads to the contraction of the stomach body muscles and the expulsion of stomach contents from the body. 2, diarrhea: mainly for the intestines are stimulated and secretions increase a lot, affecting the function of absorption, causing too much water in the intestinal cavity, plus intestinal peristalsis also increases, so the discharge of stools are thin. 3. Abdominal pain: Pain is felt because the intestinal peristalsis is doubled and faster than normal, or the mucous membrane on the intestinal wall is red and swollen due to inflammation, and although the redness and swelling is less, pain can be felt. The upper respiratory tract symptoms of gastrointestinal flu patients are relatively mild, while poor appetite, epigastric discomfort, acid reflux, heartburn, resulting in nausea, vomiting, often accompanied by abdominal pain, diarrhea, stools with watery diarrhea mainly, does not contain pus and blood. Second, the treatment of patients with gastrointestinal flu should pay attention to the following points 1, after the onset of the disease should go to the hospital to do blood and stool tests, if necessary, liver function and other related laboratory tests to exclude lesions caused by other pathogens, such as enteritis, bacterial dysentery, infectious hepatitis, etc.; 2, to pay attention to the patient’s diet, should eat a small number of meals to eat light, easily digestible food, avoid eating greasy and with 3, to pay attention to replenish water, because the patient repeatedly diarrhea, the body will lose more water and “electrolytes”, to encourage patients to drink a small number of times, the best drink some less greasy with salty vegetable soup; 4, try to reduce the oral anti-inflammatory, pain, antipyretic drugs, reduce the stimulation of the gastrointestinal tract, such as body temperature more than If the temperature exceeds 38.5 degrees, you can go to the hospital to inject Chai Hu, Advil or physical cooling; 5, if necessary, give intravenous fluids and nutrients, especially children and elderly patients must take early measures. Third, the gastrointestinal flu is easily confused with acute gastroenteritis Gastrointestinal flu mainly manifests as poor appetite, epigastric distension, acid reflux, heartburn, nausea and vomiting in severe cases, sometimes accompanied by abdominal pain, watery diarrhea, etc. At this time, the common upper respiratory symptoms of the flu may not be obvious, so it is easy to confuse with acute gastroenteritis. The main thing to distinguish these two types of diseases is the presence of improper eating in the medical history. If the symptoms of acute gastroenteritis do not improve after a few days of taking medication for the treatment of acute gastroenteritis, it should be thought that gastrointestinal symptoms are the main manifestation of gastrointestinal flu and the medication should be changed. The treatment of gastrointestinal cold is basically the same as that of typical cold The treatment of gastrointestinal cold is basically the same as that of typical cold, mainly symptomatic treatment. Anti-viral drugs such as Banlangen, Shuanghuanglian, etc. can be used as appropriate according to the condition. If you have a fever, you can use antipyretic drugs; vomiting can be used to improve appetite by using digestive aids such as morpholine. You can eat some light, easy-to-digest semi-liquid or liquid food, such as rice soup, porridge, noodles, etc. Pay attention to replenish water and electrolytes. Patients with severe diarrhea and vomiting can temporarily fast; patients with moderate to severe diarrhea must be hydrated and electrolytes replenished intravenously. In addition, antibiotic treatment is ineffective in this type of cold, and improper use can aggravate the symptoms of the gastrointestinal tract. In case of combined bacterial infection, flavopiridol and haloperidol should be used. If you need to stop diarrhea, you can use adsorbent astringent antidiarrheal drug Simethicone, which can adsorb intestinal toxins and viruses and has the effect of protecting intestinal mucosa. Therefore, do not think it is gastrointestinal infection as soon as nausea, vomiting and diarrhea appear and use antibiotics casually, but you should go to the hospital for further examination and have a correct diagnosis first in order to spend less money to cure the disease.
