Audience Guides

Plain-language guidance for the people around someone with Hereditary Hollow Viscus Myopathy — how to understand it and talk about it. AI-generated for communication, not medical advice; always confirm specifics with a clinician.

πŸ‘©β€πŸ«
TeacherA student may need accommodations — rest breaks, bathroom access, flexible deadlines, or a place for medication. Keep the care plan handy, know the warning signs, and treat the student as capable — most want to be included, not singled out.
πŸƒ
CoachAsk the family what activity is safe and what to watch for. Have an emergency plan and the family's contacts on hand. Build in rest and hydration, and adapt drills so they can take part.
πŸ’Ό
Employer / managerFocus on what helps them do the job — flexible hours, remote options, accessible space, and time for appointments. Keep health details private and let them lead on what they share.
πŸ₯
School nurseGet the care plan and medication orders on file, know the emergency steps and who to call, and coordinate quietly with teachers so the student is supported without being singled out.
πŸ‘ͺ
Family & friendsLearn the basics, ask how you can help rather than assuming, and offer specific support — a meal, a ride, or just listening. Small, steady help matters more than grand gestures.
