Dehydration leads to the aggravation of gastrointestinal (GI) complaints during exercise. The aim of this study was to examine the effect of dehydration on various GI parameters during strenuous exercise. Ten healthy well-trained men were investigated in dehydrated and in euhydrated conditions. Dehydration took place before the experiments using a dehydration regimen in a sauna [...]

This study examines the effect of the initial state of hydration on hormone responses to prolonged exercise in the heat. Five subjects at two initial hydration levels (hypohydrated and hyperhydrated) were exposed to a 36 degrees C environment for 3 h of intermittent exercise. During exercise, the subjects were either fluid-deprived, or rehydrated with water [...]
Three cases highlight the association between elevated breast milk sodium and hypernatremic dehydration in the infant. All three mothers, breast-feeding exclusively, had sodium levels in breast milk elevated significantly above normal. Severe hypernatremic dehydration in otherwise normal infants who are exclusively breast fed can be due to elevated sodium levels in breast milk. PMID: 7778332 [...]
Dehydration negatively impacts geriatric hospitalization outcomes. The purpose of this study was to investigate the hydration status of psychogeriatric inpatients and explore possible factors for dehydration. A descriptive, retrospective chart review of patients discharged from a psychogeriatric unit was completed. Clinical and biochemical information was collected at three time points (admission, mid-point, and discharge). Results [...]
This investigation determined the effect of different rates of dehydration, induced by ingesting different volumes of fluid during prolonged exercise, on hyperthermia, heart rate (HR), and stroke volume (SV). On four different occasions, eight endurance-trained cyclists [age 23 +/- 3 (SD) yr, body wt 71.9 +/- 11.6 kg, maximal O2 consumption 4.72 +/- 0.33 l/min] [...]

This investigation evaluated the effects of beverage carbonation and carbohydrate (CHO) content on fluid replacement following exercise/thermal dehydration. On four occasions separated by at least 7 days, eight healthy men cycled at 50% of VO2max in a hot environmental chamber (40 degrees C, 40% relative humidity) until a weight loss of 4.12 +/- 0.22% was [...]
This is the second article in a series of five on dementia. It aims to enhance nurses' understanding of dehydration in patients with dementia. Research shows that dehydration is present in up to one quarter of older patients and patients with dementia are likely to have an even higher risk. Dehydration may be harder to [...]
Dehydration caused by diarrhea remains a major source of morbidity and mortality worldwide. Dehydration is a common clinical presentation seen by most physicians. Clinical diagnosis depends on the recognition of signs and symptoms as well as change in weight. Laboratory studies are helpful in categorizing the dehydration as isotonic, hyponatremic, or hypernatremic, which is necessary [...]
