Introduction
Under normal circumstances, norovirus may cause vomiting, but not continuous vomiting. Norovirus is a virus that causes acute gastroenteritis. After infecting the human body, it mainly affects the gastrointestinal tract, where it extensively replicates within the epithelial cells of the gastrointestinal lining, triggering an inflammatory response. The inflammation stimulates the nerves of the gastrointestinal tract, disrupting normal intestinal motility and digestive function, leading to nausea and vomiting.
Under normal circumstances, norovirus may cause vomiting, but it does not lead to continuous vomiting. If discomfort occurs, timely medical attention is recommended. Detailed explanation is as follows:
Norovirus is a virus that causes acute gastroenteritis. After infecting the human body, it primarily affects the gastrointestinal tract and replicates extensively in gastrointestinal epithelial cells, triggering an inflammatory response. The inflammation stimulates the gastrointestinal nerves, disrupting normal intestinal motility and digestive function, leading to nausea and vomiting.
In the early stages of infection, viral replication and stimulation within the body are increasing, while the immune system is actively responding, causing a strong stress reaction that results in vomiting, which may be accompanied by abdominal pain, diarrhea, and other symptoms. However, as the immune system clears the virus and gastrointestinal inflammation gradually subsides, vomiting typically improves within 24-48 hours and does not persist continuously.
Vomiting and diarrhea can easily lead to dehydration and electrolyte imbalance. Patients are advised to replenish fluids and electrolytes adequately, maintain a light diet, and avoid spicy or irritating foods.
