Hypernatraemia most often occurs in people who don't drink enough water. This is usually because of impaired thirst or mental judgement. Examples include someone with dementia or an infant who has limited access to fluids.Symptoms vary based on the condition's severity, but include thirst, restlessness and fatigue.Treatment may include drinking more water or intravenous fluids. The main cause of hypernatremia usually involves dehydration due to an impaired thirst mechanism or limited access to water, according to the Merck Manual. The disorder can also result from diarrhea or vomiting, taking diuretics or having a high fever. Hypernatremia can occur when there is a too much water loss or too much sodium gain in the body. The result is too little body water for the amount of total body sodium. Changes in water intake or water loss can affect the regulation of the concentration of sodium in the blood. In patients with hypernatremia of longer or unknown duration, reducing the sodium concentration more slowly is prudent. Patients should be given intravenous 5% dextrose for acute hypernatremia or half-normal saline (0.45% sodium chloride) for chronic hypernatremia if unable to tolerate oral water. Citations are important for a journal to get impact factor. Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports.
