Does Dehydration Increase Blood Pressure?
While often ignored, dehydration is surprisingly dangerous, and some research suggests it could cause hypertension.
Understanding Dehydration
Dehydration happens when your body lacks enough fluid.
Common causes include:
Heavy perspiration
Vomiting or diarrhea

How Dehydration Affects Your Blood Pressure
In certain cases, dehydration may cause hypertension. Here’s why:
Dehydration increases blood viscosity
Hormonal responses cause vessel constriction
Increased workload for the heart leads to higher pressure
Staying hydrated helps prevent this.
Does Dehydration Lower BP as Well?
Dehydration may swing blood pressure in either direction:
Severe fluid loss may drop blood pressure
Mild dehydration may raise it due to hormonal shifts
The balance depends on the body’s response
