Understanding Blood Pressure Spikes During Fasting: Causes, Biomarkers & What To Do

Explore causes and personalized insights for blood pressure spikes during fasting using advanced testing with Mito Health.

Why It Happens

Blood pressure spikes during fasting are often due to stress hormone fluctuations, dehydration, or underlying imbalances. While fasting can benefit blood pressure long-term, short-term spikes may occur.

Increased Cortisol and Adrenaline: Fasting activates stress pathways that can raise blood pressure, especially in the early phases.

Electrolyte Imbalance: Without food, you may lose sodium and potassium, both critical to pressure regulation.

Dehydration: Low fluid intake leads to reduced plasma volume and higher vascular resistance.

Caffeine Use While Fasting: Stimulants on an empty stomach can spike pressure quickly.

Underlying Hypertension: Fasting may expose hidden blood pressure issues by stressing regulatory systems.

How to Manage

Stay Hydrated with Electrolytes: Drink water plus magnesium, potassium, or salt during fasting windows.

Avoid Overexertion While Fasting: Limit intense workouts if you're prone to pressure spikes.

Use Calm Support: Try adaptogens, teas, or meditation to regulate cortisol.

Avoid Fasting if Hypertensive: Check with your provider before using fasting as a tool if pressure is already elevated.

Test and Track: Use wearables or home cuffs to monitor changes throughout your fast.

Fasting can help — but if it raises pressure, the solution may be found in minerals and rhythm.
