Dehydration can potentially lead to various heart-related symptoms, including irregular heartbeats or palpitations, which some people may describe as a "fluttering" sensation in the chest. When the body is dehydrated, blood volume can decrease, leading to an increase in heart rate as the heart works harder to maintain adequate blood flow. Additionally, electrolyte imbalances due to insufficient hydration can also affect heart rhythm.
If you are experiencing heart fluttering, it's important to consult with a healthcare professional to determine the underlying cause and receive appropriate advice or treatment. Staying well-hydrated is generally important for overall health and can help prevent potential complications, including those related to heart rhythm.
