Elevated BNP Levels Explained

January 7, 2025

Elevated BNP Levels Explained Elevated brain natriuretic peptide (BNP) levels have become a notable concern for long COVID patients. BNP is a hormone produced by the heart and blood vessels in response to increased pressure, often signaling cardiovascular strain. Recent studies reveal that 15-20% of long COVID patients experience elevated BNP levels, impacting their breathing, cognitive function, exercise tolerance, and overall wellness.

What Are Elevated Brain Natriuretic Peptide (BNP) Levels?

Brain Natriuretic Peptide (BNP) is a hormone produced primarily by the heart’s ventricles in response to increased pressure and volume. Its primary role is to help regulate blood pressure and fluid balance in the body by:

Promoting Vasodilation: Widening blood vessels to reduce vascular resistance and ease blood flow.
Encouraging Sodium Excretion: Helping the kidneys excrete sodium and water to lower blood volume.
Reducing Stress on the Heart: Decreasing the workload on the heart by alleviating pressure in the circulatory system.

What Does Elevated BNP Indicate?

When BNP levels are elevated, it often signals that the heart is under stress or strain. This can occur due to a variety of conditions, including:

Heart Failure: A common cause of elevated BNP, indicating that the heart is not pumping blood effectively.
Long COVID: Persistent cardiovascular stress from the infection may cause elevated BNP levels in some patients.
Other Conditions: Kidney dysfunction, pulmonary hypertension, or acute illnesses that increase fluid retention and vascular resistance.

Normal BNP Levels vs. Elevated Levels

Normal Range: BNP levels typically remain under 100 picograms per milliliter (pg/mL).
Mild Elevation: Levels between 100-400 pg/mL may suggest early heart dysfunction or other contributing factors.
Significant Elevation: Levels over 400 pg/mL often indicate heart failure or severe cardiovascular strain.

Why Is This Relevant to Long COVID?

For long COVID patients, elevated BNP levels may result from ongoing cardiovascular or systemic inflammation caused by the virus. It serves as a critical biomarker to identify heart-related complications, enabling timely intervention and management.

Understanding and addressing elevated BNP levels can significantly improve quality of life and prevent further complications in long COVID patients.

Early detection and management are critical, as untreated elevated BNP levels can lead to worsening health outcomes. This article explores the causes, symptoms, and recovery strategies for those affected.

Symptoms of Elevated BNP in Long COVID

Breathing Difficulties: Shortness of breath and reduced oxygen levels.
Cognitive Challenges: Brain fog, difficulty concentrating, and memory lapses.
Exercise Intolerance: Fatigue and reduced endurance.
Fluid Retention: Swelling in the legs or abdomen.

Diagnosing Elevated BNP Levels

Diagnosis involves a combination of:

Blood Tests: Measuring BNP levels in the bloodstream.
Imaging: Echocardiograms to assess heart function.
Clinical Evaluation: Identifying symptoms and assessing overall health.

Recovery Strategies

1. Medications Commonly Used

Diuretics: Reduce fluid buildup and alleviate swelling.
ACE Inhibitors: Lower blood pressure and improve heart function.
Beta-Blockers: Reduce heart strain and regulate heart rate.

2. Diets That Support Recovery

Foods to Include:
- Leafy greens, avocados, and bananas (rich in potassium).
- Omega-3 fatty acids (salmon, walnuts, flaxseed).
- Whole grains (brown rice, quinoa).
- High-antioxidant foods (berries, green tea).
Foods to Avoid:
- Processed foods high in sodium.
- Sugary snacks and beverages.
- Saturated and trans fats (fried foods, processed meats).

3. Herbs: Help or Hinder?

Helpful Herbs for BNP Levels and Long COVID Recovery

Hawthorn: Supports the heart by improving blood flow and reducing blood pressure.
- Contains antioxidants that protect the heart from oxidative stress.
- Often used to manage mild heart failure and long-term cardiovascular health.
Turmeric: Reduces systemic inflammation due to its active compound, curcumin.
- Promotes better vascular health and may alleviate inflammation-related symptoms.
Garlic: Known for its cardiovascular benefits, garlic reduces blood pressure and cholesterol levels.
- Contains allicin, which supports healthy blood flow.
Ginger: Helps reduce inflammation and improve circulation.
- May also alleviate dizziness and nausea often associated with long COVID.
Ashwagandha: Acts as an adaptogen, helping the body manage stress.
- Reduces cortisol levels, indirectly benefiting cardiovascular function.
Cinnamon: Improves blood sugar regulation and has anti-inflammatory properties.
- May aid in reducing oxidative stress, supporting overall heart health.

Herbs to Avoid for BNP and Long COVID Recovery

Licorice Root: Increases fluid retention and blood pressure.
- Can exacerbate cardiovascular strain, particularly in individuals with elevated BNP levels.
Ephedra (Ma Huang): Acts as a stimulant, raising heart rate and blood pressure.
- Can trigger cardiovascular events and should be strictly avoided.
Yohimbe: Often marketed as a natural energy booster, it can increase heart rate and cause arrhythmias.
- May worsen cardiovascular symptoms.
St. John’s Wort: Interacts with many medications, including those for blood pressure and heart health.
- Can reduce the effectiveness of prescribed treatments.
Ginseng: Though often considered an energy booster, some types of ginseng may overstimulate the heart, causing palpitations and blood pressure spikes.

Additional Notes on Herb Use

Consult a Healthcare Provider: Always discuss herbal remedies with a doctor, especially if taking medications for heart health or long COVID symptoms.
Dosage Matters: Even helpful herbs can cause adverse effects if taken in excessive amounts. Follow dosage recommendations carefully.
Quality of Supplements: Choose high-quality, standardized herbal supplements to ensure safety and effectiveness.
Incorporating the right herbs into your recovery plan can provide natural support for cardiovascular health and symptom management. However, avoiding harmful herbs is equally important to prevent unnecessary complications. With proper guidance, herbs can become a valuable complement to traditional treatments.

4. Lifestyle Adjustments for Wellness

Breathing Exercises: Diaphragmatic breathing to improve oxygenation.
Light Exercise: Walking or yoga to enhance endurance without overexertion.
Stress Management: Mindfulness and meditation reduce cardiovascular strain.

The Impact on Wellness and Cognition

Elevated BNP levels in long COVID patients often disrupt cognitive function, leading to brain fog and memory challenges. These symptoms are compounded by reduced exercise tolerance and breathing difficulties, further affecting quality of life. Managing BNP levels with a holistic approach significantly improves outcomes, helping patients regain clarity, strength, and wellness.

Looking Ahead: Managing BNP for Recovery

Recovery from elevated BNP levels requires a multifaceted approach involving medical treatment, lifestyle changes, and dietary adjustments. With proactive management and support, patients can alleviate symptoms and rebuild their overall health.
