hi guys ,why edema doesn't occurs in primary hyperaldosteronism (Conn's syndrome)as there is increased aldosterone secretion which leads to increased Na reabsorption,Na retention leads to water retention too ,therefore ECF volume increases plasma volume increases then why not edema occuring in this situation ...and why edema occurs in secondary hyperaldosteronism...anyone can explain it

You said that blood volume increases, so blood pressure is also increased. Increased blood pressure causes glomerular filtration rate to increase by pressure-diuresis and pressure-natriuresis mechanism, as explained by AC Guyton. So, diuresis is increased and blood volume remains constant so there is no oedema.

oh yes itz the phenomenon called SODIUM ESCPAE... sosium is not retained excessively if there is primary aldosteronism.......which is y there is no edema
