Associated symptoms may be felt in the minutes leading up to a vasovagal episode and are referred to as the prodrome. These consist of light-headedness, confusion, pallor, nausea, salivation, sweating, tachycardia, blurred vision, and sudden urge to defecate among other symptoms. [9] Vasovagal syncope can be considered in two forms:

[5] Hypernatremia is generally defined as a serum sodium level of more than 145 mmol/L. [3] Severe symptoms typically only occur when levels are above 160 mmol/L. [1]
Other simple remedies include avoiding sudden changes in posture when sitting or lying and avoiding bright lights. Several essential electrolytes are excreted when the body perspires. When people experience unusual or extreme heat for a long time, sweating excessively can cause a lack of some electrolytes, which in turn can cause lightheadedness.
