1\u00e2\u20ac\u201aWhy we get diarrhea \u00e2\u20ac\u201c the four main mechanisms<\/strong><\/p>\n\n\n\n Most acute, watery episodes are infectious; chronic (>4 weeks) demands a work-up for malabsorption, endocrine disease, medications, etc. <\/p>\n\n\n\n 2\u00e2\u20ac\u201aWhen is it \u00e2\u20ac\u0153severe\u00e2\u20ac\u009d?<\/strong><\/p>\n\n\n\n Any of these \u00e2\u2021\u2019 go straight to a clinician or emergency department.<\/p>\n\n\n\n 3\u00e2\u20ac\u201aTreatment playbook<\/strong><\/p>\n\n\n\n 4\u00e2\u20ac\u201aWhen to seek urgent help<\/strong><\/p>\n\n\n\n 5\u00e2\u20ac\u201aStaying out of trouble next time<\/strong><\/p>\n\n\n\n Bottom line<\/strong><\/p>\n\n\n\n Diarrhea kills mainly through dehydration, so every treatment plan starts with prompt, adequate oral (or IV) re-hydration, then targets the cause or the worst symptoms. Most episodes settle in \u00e2\u2030\u00a4 3 days with ORS, zinc (for kids), and careful diet; medicines have supporting roles and antibiotics are selective tools \u00e2\u20ac\u201c not defaults.<\/p>\n\n\n\n This guidance is for education, not a substitute for individualized medical care. If any red-flag feature emerges, contact a healthcare professional immediately.<\/p>\n","protected":false},"excerpt":{"rendered":" Below is a concise \u00e2\u20ac\u0153field manual\u00e2\u20ac\u009d you can keep handy.
