Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objective: To compare the incidence of peri-colonoscopy hyponatremia associated with PEG 3350 + sports drink (PEG-SD) versus PEG 3350-electrolyte solution + sodium sulfate + sodium ascorbate and ascorbic acid (PEG-ELS).

Hypothesis: As compared to PEG-SD, hyponatremia occurs significantly less often with PEG-ELS.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Adults age 18 years or older scheduled for elective outpatient colonoscopy: 8am - noon.

Exclusion Criteria

* Unable or unwilling to consent
* Pregnant
* Breast feeding
* Significant psychiatric illness

-\> 50% colon resection
* Bowel obstruction
* History of hyponatremia (Serum sodium \<135 mmol/L)
* End stage renal disease on dialysis
* History of chronic kidney disease (other than kidney stones)
* Decompensated cirrhosis, including:

* History of bleeding due to portal hypertension (varices, gastropathy, etc) within 3 months
