Dr. George Kaysen, MD was hired by plaintiff's attorney as a medical expert. Kaysen teaches at UC Davis; his expertise is in nephrologist, specializing in kidney disease, including electrolite abnormalities.

He said that hyponatremia "happens quite commonly," especially with patients on diuretics. He spent a lot of time educationg the jury as to the technical meaning of hyponatremia; it came down to the dilution of the level of salt in the bloodstream balances with the level of salt in the cells, and that when the salt fell below a certain level, it would cause cell swelling, and brain swelling. Kaysen also said that no matter how much water a person drinks, the kidney can only process about one pint an hour; so anything ingested above that amount would not be urinated out, but would have to be absorbed by the body. He also said that the smaller the person, the greater the dilution. Jennifer was petite. Lucy Davidson, who won the contest, was much larger physically.

Kaysen said a medical "water challenge" would involve drinking one quart of water, then waiting an hour and a half to urinate. He said that amount of water drinking would have been safe for a contest, but that any doctor or nurse would have known not to exceed that amount. He cited two studies, one with 15 women in a hospital setting, who had died from water intoxication. He also testified that such loss of salt would cause impaired mental status and impaired judgment similar to alcohol intoxication. He said it was not possible to determine exactly when contestants would have felt impairment from the water.

When asked about some other contestants experience of headaches, lightheadedness, and nausea, he said that was to be expected with acute hyponatremia. Dreyer played the audio clip of Jennifer saying her head hurt, how she didn't feel well, and her belly distended, and Kaysen said those were classic symptoms of water intoxication. He said that Jennifer's judgment had been impaired, that she should not have driven herself home, and that, had she had medical attention when she left KDND at 9:40 AM, her life would have been saved.

Entercom Defense attorney Don Carlson established that water intoxication and alcohol intoxication had different effects. He also established that the Chico case was different from the Strange case in that the Matthew Carrington had been force fed water, whereas Strange had voluntarily drunk water. Kaysen admitted that while he has treated 200 cases of chronic hyponatremia, he had never treated an acute case. He also said he had never before seen anyone die from a water drinking contest. Carlson: "When I took your deposition in August of 2009, you were not aware of anyone dying from acute hyponatremia other than marathon runners or those who were severely psychiatric damaged; are you aware of anyone dying from voluntarily drinking too much water?" Kaysen: People don't generally volunteer to drink this kind of water." Carlson presses him for yes or no answer; Kaysen said no.
