Here's what people with IgAN should know about managing diarrhea:

Contact your doctor immediately if you have severe diarrhea, as it can worsen kidney function and cause dehydration. Watch for fever, weakness, vomiting or blood in stool.

Avoid common diarrhea remedies without consulting your doctor first - some OTC medications and sports drinks can be dangerous due to electrolyte content.

Follow safe food handling, wash hands frequently, and be careful with tap water when traveling to help prevent infections that cause diarrhea.

Stay alert to medication side effects - some prescriptions like antibiotics and immunosuppressants can trigger diarrhea. Talk to your doctor about adjusting doses if needed.

Remember - people with IgAN have higher diarrhea risk due to weakened immunity. Always consult your healthcare team about the safest treatment plan for your situation.
