Stomach discomfort after eating vermicelli is considered to be related to digestive disorders such as indigestion, acute gastroenteritis or chronic gastritis. 1. Indigestion: the main ingredient of vermicelli is starch, when patients consume uncooked vermicelli or excessive consumption of vermicelli, it can increase the burden on the stomach and lead to gastric distension, gastric pain, loss of appetite and other gastric discomfort symptoms. 2. Acute gastroenteritis: If patients do not pay attention to dietary hygiene during the eating of vermicelli, it can lead to the invasion of bacteria and viruses and other pathogens into the gastrointestinal tract and trigger inflammatory foci. The stimulation of inflammation can lead to different degrees of damage to the gastric mucosa and increase the sensitivity of the stomach nerves to cause gastric discomfort. 3. Chronic gastritis: patients with chronic gastritis are mainly characterized by acid reflux, heartburn, stomach pain and bloating, and there are different degrees of damage to the gastric mucosa during the onset of gastritis, because fans are not easy to digest and stimulate the damaged gastric mucosa, resulting in aggravation of chronic gastritis and triggering symptoms of gastric discomfort. If the symptoms of gastric discomfort persist after eating vermicelli, it is recommended that the patient go to the gastroenterology department of the hospital for a clear examination of the cause and symptomatic treatment.
