The honest answer is that most acute gut symptoms have a boring explanation. New magnesium, restaurant week, your period, a protein bar full of sugar alcohols. Look there first.
But cyclospora has its own signature: watery, prolonged, real fatigue, appetite loss, and a tendency to relapse right when you think you're better. That last part is the tell.
If you're dealing with persistent diarrhea right now, here's what to do:
→ Rule out the boring stuff first — medications, sugar alcohols, hormones, recent dietary changes
→ If it's been more than 2 weeks, watery, and comes with fatigue and appetite loss — get tested
→ Ask specifically for cyclospora — it will not show on a standard stool culture
Support your gut while you wait:
→ BRAT diet to calm things down — bananas, rice, applesauce, toast. Boring, gentle, effective.
→ Add in boiled potatoes, plain chicken, broth, and cooked carrots if you need more substance
→ Avoid raw vegetables, high fiber foods, caffeine, alcohol, and sugar alcohols — all will make it worse
→ Electrolytes — not just water. You're losing sodium, potassium, and magnesium with every episode.
Support your gut lining: zinc carnosine, SBIs, DGL — calming and protective while things resolve
→ S. boulardii — the queen of gut infections, specifically researched for parasitic and infectious diarrhea
The good news: cyclospora outbreaks typically peak in summer and decline significantly after August as contaminated produce cycles out. If you're symptomatic right now, you're likely at or near the peak. Treatment is straightforward once it's identified — but you have to get the right test first.
