When a patient has an infected stomach, he or she can be treated symptomatically with medications. After the patient has an infected stomach, a bacterial culture test can be performed to identify the specific pathogenic bacteria, and then symptomatic antibiotics can be given for anti-infective treatment, including metronidazole, clarithromycin and amoxicillin. Patients with gastric infection will have diarrhea, abdominal pain, nausea, vomiting and other adverse symptoms. For such adverse symptoms, antispasmodic and analgesic drugs can be used to relieve diarrhea, such as diarrhea Listeria pellets, Bifidobacterium trisporus, acetaminophen tablets, etc. For those who have severe diarrhea symptoms, it is necessary to replenish water and electrolytes through intramuscular or oral medication to prevent patients from dehydration symptoms.
