Gastroparesis with fever can have multiple causes, and can be initially distinguished from one another based on the degree of fever, duration of fever, and concurrent symptoms.
If the stomach pain is like pins and needles and persistent, with fever, vomiting, or even diarrhea, and there are obvious triggers before the onset, such as unclean diet, overeating, and other dietary factors, an acute attack of gastritis is highly suspected, and the patient can be seen in a regular hospital, with proton pump inhibitors and antibiotics, and intramuscular pain medication to relieve spasm, and the symptoms of stomach pain and fever can be significantly relieved by dietary modification and medication.
If the stomach is perforated, the stomach pain is severe, even severe pain throughout the abdomen, with pressure and rebound pain, abdominal muscle tension, etc., along with a high degree of fever and a history of previous gastric ulcer or gastric surgery, the treatment requires intensive acid suppression, intensive pain relief, intensive gastric mucosal repair, intensive antibiotic use, along with dietary abstinence, gastrointestinal decompression, and endoscopic or surgical treatment if necessary.
If the stomach is cancerous, the stomach pain is vague or severe, with persistent episodes of fever, mostly in the late afternoon or at night, but the fever is not high, usually no higher than 37.5°C, or accompanied by vomiting, wasting, and lack of desire to eat, etc. Treatment requires precise medication based on examination and test results.
