How can dehydration cause dizziness?

ANSWER

Many people don't drink enough fluids to replace the liquid they lose every day when they sweat, breathe, and urinate. It's particularly a problem for older people and people with diabetes. When you're severely dehydrated, your blood pressure can drop, your brain may not get enough oxygen, and you'll feel dizzy. Other symptoms of dehydration include thirstiness, tiredness, and dark urine. To help with dehydration, drink plenty of water or diluted fruit juice, and limit coffee, tea, and soda.
