GERD is frequent acid reflux that can irritate the esophagus and disrupt sleep and daily life. K21.9 is GERD without esophagitis. It's very manageable — usually with a few habit changes and medication — and a good plan prevents the longer-term problems reflux can cause.
Your first steps
- →Ask which habit changes (meal timing, trigger foods, head-of-bed) fit your situation.
- →Get the medication plan in writing, including how long to take it.
- →Note which symptoms persist so the team can adjust.
