diuresis

An expected physiological result can be just something like dry mouth or temporary diuresis.

So if you drink the ORS whilst still in diuresis, it won't have any negative effects, but you're more likely to urinate away the contents.

The other studies use various indirect measures of hydration (blood osmolality and urine metabolites) where it is unclear if sub-clincical diuresis would actually impact these measures.

An increase in urine output (i.e., increased diuresis) is associated with an increase in excretion of major intra- and extracellularions from the body fluids, their negative balance, and changes in body water levels and functional activity of some body water management-dependent hormones.

What's probably toxic about it at this dosage is that it cannot be eliminated by your kidneys or stored in your liver quickly enough, so it accumulates in the blood and shifts the osmolality causing neurological symptoms, osmotic diuresis and cardiac arrhythmia.

Hence, evacuating methods like bloodletting, purging, vomiting, sweating, diuresis and cauterization were the basis of the most effective general treatment until the beginning of 19th century [2–5] You just forgot to include the subsequent statement.

The World Health Organization investigated the health effects of demineralised water in 1982, and its experiments in humans found that demineralised water increased diuresis and the elimination of electrolytes, with decreased serum potassium concentration.[citation needed] Magnesium, calcium, and other nutrients in water can help to protect against nutritional deficiency.

This receptor of transmembrane protease acts in the conversion of angiotensin 1-8 (Ang II) to angiotensin 1-7 (Ang 1-7), prompting diuresis/natriuresis, preserving renal function, and attenuating cardiac and vascular reformation (Vickers et al., 2002; Santos et al., 2008; Zhang et al., 2010).
