it makes sense, because increasaed aldosterone (conn's) will result in:

- inc Na reabsorption
- inc K secretion (hypokalemia)
- inc H ion secretion (metabolic alkalosis)


And it's the exact opposite situation with addison's disease (lack of aldosterone)

Aldosterone stimulates an increase in the luminal H ATPase channel...which facilitates the secretion of H ions, causing a metabolic alkalosis.

The H ions leaving is what drives the reaction CO2 + H20 ---> H2CO3 ---> H ion + HCO3- in the cells.

^^the H ion gets secreted. the HCO3- is NEW bicarb, which gets transported into the blood. This causes the metabolic alkalosis.
