Overhydration or water intoxication can occur when the concentration of electrolytes in the body, particularly sodium, becomes diluted due to excessive water intake.
The recommended daily water intake varies based on factors such as age, gender, weight, activity level, and medical conditions.
Overhydration can be caused by certain medical conditions or medications that impair the body's ability to excrete water or increase its tendency to retain water.
Symptoms of overhydration can range from headaches and fatigue to seizures, coma, and even death, and can be similar to those of other medical conditions.
