Symptoms and Causes of Functional Gastroenteritis

Symptoms of functional gastroenteritis include diarrhea, abdominal distension, abdominal pain, etc. The specific analysis is as follows: 1. Diarrhea due to functional gastroenteritis will cause gastrointestinal dysfunction, resulting in complete excretion of food without digestion, which is easy to cause diarrhea. 2. Abdominal distension due to functional gastroenteritis causes gastrointestinal motility to slow down, which will make food stay in the gastrointestinal tract for a long time, easy to decompose and ferment to generate more gas, flooding the gastrointestinal tract, resulting in abdominal distension.3. Abdominal pain due to functional gastroenteritis Inflammatory factors released will stimulate gastrointestinal smooth muscle, resulting in smooth muscle spasm, abdominal pain. The causes of functional gastroenteritis include dietary factors, drug factors, infectious factors, etc. The specific analysis is as follows: 1. Dietary factors Because patients eat a large number of spicy and irritating foods for a long time, such as onion, pepper, cinnamon, etc., they will stimulate the gastrointestinal mucosa, resulting in functional gastroenteritis. 2. Drug factors Because patients take a large number of non-steroidal anti-inflammatory drugs such as clofenac sodium sustained-release tablets, nimesulide tablets and acetaminophen sustained-release tablets for a long time, they are easy to damage gastrointestinal mucosa and appear functional gastroenteritis. 3. Infection factors Because the body is invaded by pathogens such as Escherichia coli, Staphylococcus aureus and Salmonella, it will affect the normal function of gastrointestinal tract and cause functional gastroenteritis.
