Most bouts of diarrhoea clear up on their own within days, yet the conversation around the topic has intensified significantly in recent weeks. With more than 17,000 reported cases of cyclosporiasis—a parasitic infection often linked to contaminated produce—spanning across the United States, many are left wondering how to handle stomach troubles effectively.
The good news? While deeply unpleasant, diarrhoea is usually manageable at home with the right approach.
When to See a Doctor
The majority of diarrhoea episodes resolve themselves within three to four days, according to Dr. Benjamin Levy, a gastroenterologist at the University of Chicago. However, certain warning signs demand professional attention.
Seek medical care if symptoms persist beyond a week, or if you experience any of the following: a fever reaching 101°F (38.3°C) or higher, blood or mucus in your stool, severe abdominal pain, vomiting lasting more than two to three days, or the frustrating sensation of needing to use the toilet without producing anything.
Dehydration represents another critical concern. While thirst is the most obvious indicator, a more reliable measure is urine output. If you’re consuming plenty of fluids yet producing urine less frequently than every six hours, something may be amiss. Watch for lightheadedness, confusion, and dark-coloured urine as additional red flags.
“If you’re dehydrated enough to need IV fluids, there may be something more serious going on,” Dr. Levy cautions, warning against the temptation of walk-in “hydration spa” IV treatments.
Certain groups should err on the side of caution. Those aged 65 and above often have diminished awareness of thirst, so contact a clinician within 24 hours of symptoms appearing. The same applies if you have kidney disease, a compromised immune system, or recently finished a course of antibiotics or a hospital stay.
Fuel and Fluids: What to Consume
Staying hydrated stands as the absolute priority. In the early stages, water, tea, and sports drinks help replace lost fluids and electrolytes effectively.
When signs of dehydration emerge, however, switch to an over-the-counter oral rehydration solution such as Pedialyte. These formulations contain lower concentrations of sugar and salt than standard sports drinks, enabling better absorption and more effective reduction of bowel movements.
Forget the old advice about surviving on clear liquids or the once-popular BRAT diet (bananas, rice, applesauce, toast). There’s no need for such strict restrictions.
That said, certain foods can worsen symptoms. Dr. Levy advises avoiding fatty and spicy dishes, high-fibre foods including whole grains and raw fruits and vegetables, alcohol, caffeine, and overly sugary beverages or those containing artificial sweeteners.
When appetite permits, tuck into modest portions from permitted categories—broth-based soups with chicken or tofu, starchy foods, and eggs all make sensible choices. Dairy deserves special mention: diarrhoea frequently triggers temporary lactose intolerance, so skip the milk and cheese while symptoms persist, though yoghurt is usually well tolerated.
Finding Relief: Medications and Comfort Measures
For symptom relief, most adults can safely take bismuth subsalicylate (commonly known as Pepto-Bismol) for a couple of days to reduce both frequency and cramping. One side effect to note: your stool may turn black—this is harmless.
Loperamide (sold as Imodium) offers another option, though strict conditions apply. Only take it if your diarrhoea contains no blood, you have no fever, and you haven’t completed a course of antibiotics within the past three months.
Always follow package directions for dosing, and consult your doctor before taking either medication if you have underlying health conditions.
For physical comfort, Dr. Levy recommends moistening soft toilet paper and gently patting rather than rubbing after using the bathroom. Steer clear of alcohol-based wipes, which can dry and irritate sensitive skin. Barrier ointments containing zinc oxide, dimethicone, or petroleum jelly applied after each visit provide protective coverage, while a simple sitz bath—just a few inches of warm water in the tub—can soothe irritation remarkably well.
For more pronounced itching or inflammation, low-dose hydrocortisone creams or those containing lidocaine, available over the counter, may offer relief.
One thing worth leaving on the shelf? Probiotics. “Not recommended,” Dr. Levy states unequivocally, despite what wellness influencers might suggest.
Protecting Others: Hygiene Matters
If a contagious condition underlies your symptoms, you may remain infectious for days or even weeks after feeling better. The transmission route is straightforward: hand-to-mouth.
Scrub your hands, fingernails, and wrists thoroughly with soap and water, particularly after using the bathroom and before handling food. Skip cooking for others while you’re unwell. If possible, remain home from work until symptoms fully resolve.
Why it Matters
With tens of millions of diarrhoea cases occurring annually in the United States alone—and cyclosporiasis cases climbing past 17,000 this season—understanding how to manage this common ailment has become increasingly relevant. Most episodes require no medical intervention beyond rest and rehydration, yet recognising when symptoms signal something more serious can prevent complications, particularly dehydration, which accounts for thousands of preventable hospital admissions each year. For otherwise healthy individuals, the difference between a miserable few days at home and an unnecessary trip to A&E often comes down to knowing which foods settle the stomach, which medications help safely, and precisely when professional assessment becomes essential. This knowledge empowers people to handle routine stomach troubles confidently while reserving medical resources for those who genuinely need them.
