Fever
Many diseases, including gastrointestinal ailments, cause fever. Abdominal illnesses impact the stomach, intestines, liver, gallbladder, and pancreas. Fever may indicate a stomach infection, inflammation, or other illness.
Common abdominal illnesses that produce fever:
Gastroenteritis: Viral or bacterial infections induce stomach and intestinal inflammation. Diarrhoea, stomach discomfort, nausea, vomiting, and fever are symptoms.
Appendicitis: The little, finger-like appendix connected to the big intestine becomes inflamed. Appendicitis causes severe stomach discomfort, fever, and nausea.
Diverticulitis: Colonic pouches are inflamed. Fever, stomach ache, and diarrhoea are symptoms.
Cholecystitis: The gallbladder, a small organ that stores bile, is inflamed. Fever, stomach discomfort, and nausea are symptoms.
Pancreatitis: The pancreas, which generates digestive enzymes and hormones, becomes inflamed. Fever, stomach discomfort, and nausea are symptoms.
Inflammatory bowel disease (IBD): Crohn's and ulcerative colitis are types of IBD. Abdominal discomfort, diarrhoea, fever, and weight loss are symptoms.
Irritable bowel syndrome (IBS): This digestive illness causes stomach discomfort, bloating, constipation, and diarrhoea. IBS seldom causes fever.
Causes: Infection, inflammation, and immunological reactions may induce stomach fever. Fever often indicates an illness or inflammation. A stomach or intestinal infection usually causes a fever in gastroenteritis.
Fever in abdominal diseases may cause:
Dehydration: Fever causes perspiration, which may dehydrate if fluids are not supplied.
Septic shock: Bacterial infections may induce life-threatening sepsis, which can damage many organs.
Electrolyte imbalances: Prolonged fever may cause muscular weakness, disorientation, and other symptoms.
Peritonitis: A bacterial infection of the abdominal cavity lining can cause pain in the abdomen, fever, and other symptoms.
Pneumonia: Some abdominal disorders can cause pneumonia, a lung infection that causes fever, coughing, chest pain, and other symptoms.
Renal failure: Fever can cause kidney damage or failure, which can cause fatigue, confusion, and decreased urine output.
