Dehydration is a common condition that can occur when you lose more fluids than you take in. It’s important to know the signs and symptoms of dehydration so you can treat it before it becomes a more serious problem. Dehydration can cause many different symptoms, some of which are serious.
Here are some of the symptoms of dehydration you should not ignore.
Headache - If you have a headache, it could be a sign of dehydration. Dehydration can cause headaches because when you're dehydrated, your blood volume decreases and your brain tissue shrinks. This can lead to headaches, migraines, and even dizziness. If you're experiencing a headache, it's important to drink plenty of fluids and see a doctor if the pain is severe. Dehydration can be dangerous, so it's important to seek medical attention if you think you may be dehydrated.
Dry mouth - Dry mouth is one of the earliest and most noticeable symptoms of dehydration. When you are even slightly dehydrated, your mouth and throat can feel dry and sticky and it may be difficult to swallow. In more severe cases, your mouth may feel very dry, your tongue may swell and crack, and you may have trouble speaking. Dehydration can also cause bad breath. This is because when your body is lacking in fluids, it starts to break down glycogen (a sugar molecule) for energy, which produces ketones. These ketones are then secreted in your breath, giving it a sweet or fruity smell.
Loss of appetite - If you notice that you're not as hungry as usual or that your appetite has diminished, it could be a sign of dehydration. When you're dehydrated, your body doesn't have enough fluids to function properly, which can lead to a loss of appetite. If you're not getting enough fluids, your body will prioritize other functions over digestion, which can result in a decrease in appetite. Dehydration can also cause fatigue, which can further contribute to a loss of appetite. If you're feeling tired and sluggish, it's more difficult to muster up the energy to eat. And if you're not eating enough, your body won't have the fuel it needs to function at its best. If you're experiencing a loss of appetite along with other symptoms of dehydration, it's important to take action and rehydrate yourself.
Dizziness - If you experience dizziness, it is important to drink plenty of fluids and seek medical attention if the dizziness is severe. Dehydration can cause your blood pressure to drop, which can lead to light-headedness and dizziness. You may also experience dizziness if you are dehydrated due to heat exhaustion or heat stroke.
