Do You Know the Signs of Dehydration?

Did you know that if you reach for a drink because you feel thirsty that you are already dehydrated? While mild dehydration may be resolved by sipping a glass of water, ignoring the symptoms and allowing it to progress can lead to serious health complications, including heart emergencies. Stay aware of these symptoms of dehydration so you can take action to prevent complications.


As mentioned, thirst is an indicator that you are already dehydrated, not a warning to drink before dehydration hits. With mild to moderate dehydration, you may notice an increase in your thirst and your mouth may feel dry and sticky. As dehydration becomes more severe, so does thirst. Your mouth may feel extremely dry and your tongue may become swollen. Once you become severely dehydrated, you may dramatically increase your fluid intake without increasing your urine output, as your body tries to hold onto the water. You may stop urinating completely, or your urine may appear much darker than normal, despite drinking more fluids.

Rapid Heart Rate

Being dehydrated can upset the electrolyte imbalance in your body and make your heart work harder to supply your cells with nutrient-rich blood, so many people experience rapid heartbeats when they are dehydrated. This can be particularly dangerous for people with existing heart disease or other chronic conditions. Often, rapid heart rate caused by dehydration is also accompanied by rapid breathing.


Dehydration plays a role in a large number of headaches, and chronic dehydration can lead to chronic headaches. The lack of water in the body causes muscle tension, which in turn can cause headaches. Increasing fluid intake can be the key to reducing chronic headaches for some people.
