Signs and Symptoms: \textbf{{\color{#4257b2}Signs and Symptoms: }}Mainly, they are a result of brain cell edema, including headache, nausea, lethargy, and disorientation. More severe symptoms can occur if fall in sodium levels was too rapid, such as seizures, coma, permanent brain damage, and death. Brain cell edema can be less severe (and so signs and symptoms) if fall in sodium levels was more slowly.


Dehydration \textbf{{\color{#4257b2}Dehydration }}can be due to excess water loss\textbf{excess water loss} (such as diarrhea and vomiting), or inadequate water intake\textbf{inadequate water intake} (such as fasting).
