More severe symptoms include confusion, lightheadedness, dizziness, and rapid heart rate. If you fear you may have serious dehydration, Banach recommends being evaluated in the emergency department in case you need intravenous fluids. Of course, you can also overdo it in the other direction: There's such a thing as overhydration , which poses its own unique set of problems—such as dangerously low sodium levels in the blood.
But for most people, that's generally not a risk they'll run unless they really overdo it; a healthy adult male would have to drink close to six gallons in a day to risk those kinds of side effects. Generally speaking, if you're running a fever, it helps to be liberal when it comes to refilling your water glass: Bernacki recommends drinking an additional eight ounces of water than you normally would for every degree of body temperature you have over Bernacki also subscribes to the idea that 64 ounces of water a day is a good median baseline to shoot for.
It's something that any person who becomes sick with a virus, particularly the flu, needs to be aware of. Bernacki also says proper hydration can help your body use medication better, which may lead to a quicker alleviation of symptoms. Most of the time, you'll simply want to shoot for drinking six to eight glasses of water a day, increasing that intake if you have a fever, diarrhea, or vomiting.
And if you're really losing liquids, replenish your body with an electrolyte-enhanced beverage. Usually, the infection turned out to be more severe than initially anticipated. The children then suffered something called cerebral oedema, which is extra fluid in the brain. This can cause convulsions and brain damage because of the restricted space inside the skull, and can even lead to death. It might have been some effect of the infection, of course.
But the doctors all suggested it might have simply been the extra fluids the patients were given — sometimes by the medicos themselves by intravenous drips in a few cases. This could be the result of the body secreting Anti-Diuretic Hormone, which temporarily shuts off our kidneys from excreting urine. This occurs in times of severe stress.
Anti-Diuretic Hormone probably evolved in order to protect us mammals from dying of fluid loss when wounded or very ill. Liquids taken in by mouth and by infusion are measured as is the urinary output. Calculations as to how much liquid volume is lost by respirations, sweating, etc.
The hydration of a sick patient is very important to recovery. The easiest way is to keep an eye on urinary function. If you are getting dehydrated, your urine output will decrease and the urine will become dark as your kidneys function to preserve water. If you are taking enough liquids to cover normal needs and the extra needs of an illness, your urine will be pale and between one and two liters per day.
