Can Dehydration Cause Dizziness?

Dehydration occurs when you lose more water than you take in, and it’s something most of us are guilty of from time to time. When your body becomes dehydrated, it will hold onto the water it has left—this can lead to dizziness when standing up too quickly, but other factors can also cause the feeling. Here we look at why and how dehydration can cause dizziness and what to do if this happens beyond just drinking water.

Dehydration and dizziness

One of three things could be causing it: A blood sugar imbalance that’s making you lightheaded (hypoglycemia), an overactive thyroid gland that makes your heart beat faster and raises your blood pressure (hyperthyroidism), or a lack of fluid in your body caused by dehydration. If you’re not feeling well-hydrated already, drink lots of water.

Dehydration can lead to dizziness for a couple of reasons: if you’re dehydrated, your blood doesn’t carry as much oxygen to your brain, and if you’re not well-hydrated when you stand up from a lying position, your body becomes unbalanced and lightheadedness results.

Symptoms of dehydration

Dehydration occurs when you lose more fluid than you take in. Your body’s natural response to dehydration is to produce adrenaline and noradrenaline, which will help constrict blood vessels near your skin so that less blood leaves your core. This results in a drop in blood pressure, which can lead to lightheadedness or dizziness. In severe cases of dehydration, fainting may occur.

The most common reason for lightheadedness and dizziness is a drop in blood pressure as a result of dehydration. If you’re experiencing similar symptoms, drink up! Thirst is usually an indication that your body’s dehydrated. Stay hydrated by drinking plenty of water and other fluids throughout the day to avoid future bouts of lightheadedness or dizziness.

What you should do when you start getting dizzy

If you’re dizzy, take a few minutes to rest before attempting to stand. Once you feel well enough to move, slowly get up and walk around for a bit. If your dizziness isn’t relieved by these actions, drink some water and try again in 20 minutes. If your symptoms still haven’t subsided after an hour of rest or drinking water, it could be that something else is wrong—and a trip to your doctor may be in order.

Dehydration is a common cause of dizziness and lightheadedness because your body isn’t receiving enough fluids to function properly when you’re dehydrated. If you drink water or some other type of rehydrating beverage and your symptoms don’t go away quickly, it could be an indication that you have another medical condition that needs to be addressed.

Preventing dehydration on a day-to-day basis

It’s important to drink water daily. The general rule is that you should be drinking half your body weight in ounces of water (if you weigh 150 pounds, for example, then you should be drinking 75 ounces of water each day). It’s also helpful to schedule regular times throughout your day when you can step away from your desk and head to the bathroom for a quick break.

For those that struggle to maintain enough water consumption or to look for a quick pick me up when you’re dehydrated, consider IV therapy. These can be done right from your home during a time that’s convenient for you. Companies like Drip Hydration will deliver an IV bag containing saline and vitamins directly into your bloodstream, replenishing fluids and nutrients in minutes.
