Can I consume black coffee with a diastolic blood pressure range of 90-98 mmHg?

Coffee Consumption with Diastolic Blood Pressure of 90-98 mmHg

You should temporarily avoid black coffee until your blood pressure is better controlled, as your diastolic blood pressure of 90-98 mmHg indicates uncontrolled hypertension. 1

Understanding Your Blood Pressure Status

Your current diastolic blood pressure range of 90-98 mmHg is classified as uncontrolled hypertension:

• According to the British Hypertension Society guidelines, diastolic blood pressure ≥90 mmHg is considered hypertensive 2
• The American College of Cardiology/American Heart Association specifically advises avoiding coffee consumption in patients with uncontrolled hypertension 1

Effects of Coffee on Blood Pressure

Coffee consumption has different effects on blood pressure:

• Short-term effects: Coffee can cause acute increases in blood pressure immediately after consumption 1
• In a meta-analysis of randomized controlled trials, caffeine intake was shown to increase systolic BP by 4.16 mmHg and diastolic BP by 2.41 mmHg 3
• When consumed through coffee, the effect was smaller but still present (systolic: 1.22 mmHg; diastolic: 0.49 mmHg) 3

Recommendations Based on Your Blood Pressure Status

1. For your current status (uncontrolled hypertension):

   • Temporarily avoid coffee consumption until your blood pressure is controlled 1
   • Focus on lifestyle modifications to lower blood pressure, including:
     • Salt reduction
     • Healthy diet (rich in whole grains, fruits, vegetables)
     • Regular physical activity
     • Weight management if needed
     • Alcohol moderation 2

2. Once your blood pressure is controlled (diastolic <90 mmHg):

   • You may resume moderate coffee consumption (1-3 cups/day) 1
   • Limit caffeine intake to less than 300 mg/day 1

Important Considerations

• If you're taking blood pressure medications, continue them as prescribed
• Monitor your blood pressure regularly to track improvements
• The target for diastolic blood pressure should be ≤80 mmHg according to current guidelines 2
• Once your blood pressure is controlled, moderate coffee consumption is not associated with increased cardiovascular risk 1, 4

Alternative Beverages During This Period

While avoiding coffee, consider these alternatives:

• Herbal teas without caffeine
• Decaffeinated coffee (if you enjoy the taste of coffee)
• Water infused with fruits for flavor

Remember to discuss your blood pressure management plan with your healthcare provider, who can provide personalized recommendations based on your complete medical history.
