Dietary salt raises blood pressure in certain individuals immediately after ingestion (acute salt sensitivity; ASS) while not affecting others. It is hypothesized that ASS is a risk factor for hypertension. However, no thresholds or diagnostic guideline is available for ASS. This study is the first aim in the main study (HIPO CAP DITSH Study) aimed at determining the threshold or blood pressure cut-offs for ASS upon ingesting dietary salt.
