dehydration symptoms blood pressure
What is dehydration? Dehydration is an excessive loss of water from the body tissues, often accompanied by an imbalance of sodium, potassium, chloride, and other electrolytes. It can occur whenever fluids are lost and not adequately replaced, especially when an individual does not drink enough fluids. Early dehydration has no symptoms; mild or moderate dehydration can cause symptoms that include: thirst, fatigue, muscle cramps, dizziness, and headache. Severe dehydration can cause more serious symptoms, such as confusion, low blood pressure, unconsciousness, shock, and may even lead to death. The human body consists of about 60-70% water and must have a continuous supply in order to function.
