,,,is an intoxication resulting from the excessive intake of sodium (usually as sodium chloride,,,
,,,typically results in a feeling of confusion and jitteriness; more severe degrees of intoxication can cause seizures and coma. Death can result if medical intervention is not forthcoming. These symptoms are generally a consequence of hypernatremia—an abnormally high sodium level in the blood. (There are myriad causes of hypernatremia, which is frequently encountered in medical practice; salt poisoning is not a common cause.)
Early on, the intoxicant will experience a strong feeling of thirst, followed by weakness, nausea, and loss of appetite. More severe symptoms ensue, including confusion, muscle twitching, and bleeding in or around the brain. Death results by the swelling of the brain against the skull. (Normal serum sodium levels are 135 – 145 mEq/liter (135 – 145 mmol/L). Severe symptoms typically only occur when levels are above 160 mEq/L.) The human renal system actively regulates sodium chloride in the blood within a very narrow range around 9 g/L (0.9% by weight).
Accidentally consuming small quantities of clean seawater is not harmful, especially if the seawater is taken along with a larger quantity of fresh water. However, drinking seawater to maintain hydration is counterproductive; more water must be excreted to eliminate the salt (via urine) than the amount of water obtained from the seawater itself.
In most open waters concentrations vary somewhat around typical values of about 3.5%; drinking seawater temporarily increases blood's NaCl concentration, which signals the kidney to excrete sodium. However, seawater's sodium concentration is above the kidney's maximum concentrating ability. Eventually the blood's sodium concentration rises to toxic levels, removing water from cells and interfering with nerve conduction, ultimately producing fatal seizure and cardiac arrhythmia.Salt poisoning can cause Hypernatremia,
also spelled hypernatremia, is a high concentration of sodium in the blood. Early symptoms may include a strong feeling of thirst, weakness, nausea, and loss of appetite. Severe symptoms include confusion, muscle twitching, and bleeding in or around the brain. Normal serum sodium levels are 135 – 145 mmol/L (135 – 145 mEq/L). Hypernatremia is generally defined as a serum sodium level of more than 145 mmol/L. Severe symptoms typically only occur when levels are above 160 mmol/L.
The cornerstone of treatment is administration of water to correct the relative water deficit,,, However, overly rapid correction of hypernatremia is potentially very dangerous,,, Therefore, significant hypernatremia should be treated carefully by a physician or other medical professional with experience in treatment of electrolyte imbalance
