From the Guidelines
To manage dyspepsia and frequent stools after a gastrointestinal infection, start with dietary modifications and over-the-counter medications, prioritizing antacids, H2 blockers, or proton pump inhibitors for dyspepsia, and loperamide for frequent stools, as recommended by the British Society of Gastroenterology guidelines on the management of functional dyspepsia 1. The guidelines suggest that all patients with functional dyspepsia should be offered a stool test or breath test to look for a stomach infection called H. pylori, and if the test is positive, they should receive a short course of antibiotic treatment for the infection to see if their symptoms improve. For patients with dyspepsia, trying antacids like Tums or Rolaids for immediate relief, or H2 blockers such as famotidine (Pepcid) 20mg twice daily or proton pump inhibitors like omeprazole (Prilosec) 20mg once daily before breakfast for 2-4 weeks can be beneficial. Additionally, for frequent stools, loperamide (Imodium) 2mg after each loose stool (maximum 8mg daily) can help reduce diarrhea, and probiotics containing Lactobacillus or Saccharomyces boulardii may restore gut flora balance; take as directed on the package for 2-4 weeks. It is also essential to stay well-hydrated with water and electrolyte solutions, as these symptoms often represent post-infectious irritable bowel syndrome or functional dyspepsia, which typically improve gradually over 4-12 weeks as the gut microbiome recovers from the infection 1. If symptoms persist beyond 2-4 weeks, worsen, or if you experience alarm symptoms like weight loss, blood in stool, or severe abdominal pain, seek medical attention for further evaluation, as recommended by the guidelines for the management of irritable bowel syndrome 1. The British Society of Gastroenterology guidelines on the management of functional dyspepsia provide the most recent and highest quality evidence for managing dyspepsia and frequent stools after a gastrointestinal infection, and should be prioritized in clinical practice 1. Key considerations include:
- Dietary modifications to avoid spicy foods, caffeine, alcohol, and fatty foods that can worsen symptoms
- Over-the-counter medications such as antacids, H2 blockers, or proton pump inhibitors for dyspepsia, and loperamide for frequent stools
- Staying well-hydrated with water and electrolyte solutions
- Seeking medical attention if symptoms persist or worsen, or if alarm symptoms are present. Overall, the management of dyspepsia and frequent stools after a gastrointestinal infection should prioritize a step-wise approach, starting with dietary modifications and over-the-counter medications, and progressing to further evaluation and treatment if symptoms persist or worsen, as recommended by the British Society of Gastroenterology guidelines on the management of functional dyspepsia 1.

From the Research
Managing Dyspepsia
- Dyspepsia is a chronic or recurrent pain or discomfort centered in the upper abdomen, and its management depends on various factors, including the presence of alarm features and the patient's age 2.
- Patients with predominant or frequent heartburn or acid regurgitation should be considered to have gastroesophageal reflux disease (GERD) until proven otherwise 2.
- For patients over 55 years of age or those with alarm features, prompt esophagogastroduodenoscopy (EGD) is recommended 2.
Managing Frequent Stools
- Loperamide is an effective therapy for a variety of diarrheal syndromes, including acute, nonspecific (infectious) diarrhea, and diarrhea-predominant irritable bowel syndrome 3, 4, 5.
- Loperamide works by decreasing peristalsis and fluid secretion, resulting in longer gastrointestinal transit time and increased absorption of fluids and electrolytes from the gastrointestinal tract 5.
- It is also considered to be free of abuse potential and has minimal central nervous system effects due to its low oral absorption and inability to cross the blood-brain barrier 5.
Treatment Options
- Current pharmacological treatment of irritable bowel syndrome diarrhea predominant (IBS-D) includes loperamide, bile acid sequestrants, antispasmodics, tricyclic antidepressants, alosetron, eluxadoline, and rifaximin 6.
- For dyspepsia, treatment options include testing and treating for Helicobacter pylori (H. pylori) and empirical trials of acid suppression with a proton pump inhibitor (PPI) 2.
- Prokinetics are not currently recommended as first-line therapy for uninvestigated dyspepsia, and the management of functional dyspepsia is challenging when initial antisecretory therapy and H. pylori eradication fails 2.
