About Secondary Endolymphatic Hydrops

Secondary Endolymphatic Hydrops (SEH) is a condition in which the endolymph fluid of the inner ear does not remain at a consistent volume. When the volume builds, symptoms such as dizziness and pressure or fullness of the ear happen. While similar to Meniere’s Disease, SEH is not auto-immune related, but is caused by external reasons, such as physical trauma.

Usually these attacks can be avoided by taking a diuretic to help maintain fluid levels and by following a diet low in sodium and sugar (if needed). Usually sodium is limited to about 2500-3000 mg a day if a diuretic is prescribed. If not, or for purposes of self testing at home, then somewhere around 1500 mg is appropriate.
