Summary

The goal of this clinical trial is to evaluate the feasibility of low-sodium diet to improve eczema severity. The main questions it aims to answer are:

* Does a low-sodium diet improve eczema severity?
* How does a low-sodium diet impact skin sodium concentration?
* Is skin sodium concentration associated with eczema severity?

Researchers will ask all participant to follow a low-sodium diet, then compare sodium tablets to a placebo (a look-alike substance that contains no drug) to specifically examine the impact of altering sodium intake.

Participants will:

* Follow a low-salt diet for the duration of the 24-week study
* Take sodium chloride tablets every day for 5 weeks followed by a placebo every day for 5 weeks after a 2-week washout period, or vice versa
* Complete up to 4 virtual check-in visits
* Visit the clinic 4 times to answer questionnaires, provide bio samples, complete dietary recalls, and undergo non-contrast sodium MRI

Conditions

OTHER

Placebo Tablets

During the 5-week long placebo period, participants will receive five placebo tablets each morning and four placebo tablets each evening
