Viral infection is a common cause of gastroenteritis, and many viruses can cause gastroenteritis. Rotavirus is the most common virus, followed by some astroviruses. The type and severity of gastroenteritis symptoms depend on the type and quantity of microorganisms and toxins.
The most common symptom is diarrhea. Other symptoms include abdominal pain, nausea, vomiting, fever, loss of appetite, weight loss, excessive sweating, wet and cold skin, muscle pain or joint stiffness, and fecal incontinence.
Severe vomiting and diarrhea can quickly lead to dehydration, mainly manifested as collapse, extreme thirst, oliguria or dark urine color, dry skin, dry mouth and sunken eyes.
Severe vomiting or diarrhea can lead to hyponatremia, hypokalemia and hypotension.
The main groups of acute gastroenteritis are people who drink a lot, people with serious diseases and people with weak physical resistance. The etiology of acute gastroenteritis is also very complicated. The most common causes are bacterial and viral infections, among which the more common pathogens are Staphylococcus aureus, halophilic bacteria and Salmonella.
In addition to the above reasons, drug abuse, incorrect living habits, endocrine abnormalities, eating cold food and weak body resistance can also cause diseases.
The onset of acute gastroenteritis is relatively sudden. The most prominent symptom after the onset of the patient is mild diarrhea, and the number of defecation is about ten times a day.
Acute gastroenteritis is characterized by recurrent attacks. If attacks occur frequently, patients will have symptoms of general malaise such as loss of appetite, nausea and vomiting, abdominal distension, difficulty in defecation, irregular fever, irritability and listlessness, and some patients will also have complications such as sepsis, intestinal perforation and imbalance of water and electrolyte.
If you find yourself with acute gastroenteritis, you must pay attention to it and go to a doctor for a physical examination immediately. The common methods to check the condition are routine stool examination, routine blood examination and white blood cell count examination.
