When you drink too much water, your brain really expands in size and presses against the skull. A throbbing headache can result from the additional strain.
The ability to control urination can be "untrained" if you frequently overfill your bladder or hold in your urine for an extended period of time.
The best way to tell if your body needs more water is to pay attention to whether or not you feel thirsty. If you drink even though you don't want to, you drink too much.
If you drink enough water, your urine should be straw-colored to clear yellow. But if your urine is clear, you're probably drinking too much water.
On average, a person will urinate between six and ten times per day; therefore, if you urinate more than ten times per day, you may be drinking more water than your body requires.
You can hold up to 30 ounces of fluids in your bladder until you're ready to urinate. Overhydration can cause bladder leakage in persons who try to "hold it" longer.
Your kidneys can't remove excess water if you drink too much. That causes nausea, vomiting, and diarrhea from water retention.
Hyponatremia frequently manifests as edema or discolouration of the hands or lips. Your skin will swell in tandem with the swelling of all of your body's cells.
Too much water causes electrolyte levels to decline, compromising equilibrium. Low electrolytes cause muscular spasms and cramps.
