Severe dehydration can cause changes in blood pressure, resulting in chest pain. When you’re dehydrated, less blood, oxygen, and nutrients are transported to your organs, prompting the body to increase heart rate and constrict blood vessels, which can lead to chest pain. In some cases, chest pain from dehydration may also indicate an underlying heart issue. If you experience chest pain due to dehydration, seek medical attention.
Other side effects of dehydration
Aside from chest pain, dehydration can cause dry mouth, dark colored urine, fatigue, dizziness, and more. Dangerous dehydration symptoms include confusion, fainting, rapid heart rate, and shock. If you experience any of these symptoms, seek medical attention immediately.
How to treat and prevent dehydration
Drinking enough water is the best way to prevent dehydration. Your hydration needs depend on various factors, but aiming for 9 to 12 cups of water per day is generally recommended. Monitoring the color of your urine can also indicate hydration levels. Mild dehydration can typically be resolved by drinking more fluids, while severe dehydration requires medical attention for IV fluid rehydration and close monitoring.
When to see a doctor
If you experience chest pain along with symptoms like confusion, dizziness, fainting, or heart palpitations, seek medical attention immediately. Additionally, if the chest pain is persistent and accompanied by other concerning symptoms, it’s important to seek medical help to rule out any underlying health issues.
