Parasites and High Blood Presure

April 10, 2024 6 mins to read

If you have high blood pressure and can’t get any answers, you may be asking the question Can parasites cause high blood pressure? Parasites causing high blood pressure, also known as parasitic-induced hypertension, is a complex phenomenon with various underlying mechanisms. One common example is the parasite Schistosoma mansoni, which can lead to a condition called schistosomiasis-associated pulmonary arterial hypertension (PAH).

How Parasites Can Contribute to High Blood Pressure

Here’s an overview of the biochemistry behind how parasites can contribute to high blood pressure:

  1. Inflammation and Immune Response: Parasitic infections often trigger an inflammatory response in the host’s body. Chronic inflammation can lead to endothelial dysfunction, where the lining of blood vessels (endothelium) becomes damaged. This dysfunction can result in the constriction of blood vessels, increasing blood pressure. Additionally, the immune response mounted against the parasite can cause further damage to blood vessels.
  2. Vasoactive Molecules: Parasites release various molecules into the bloodstream, including vasoactive substances such as serotonin, histamine, prostaglandins, and cytokines. These substances can directly influence vascular tone and promote vasoconstriction, leading to elevated blood pressure.
  3. Fibrosis and Remodeling: Chronic parasitic infections can lead to tissue fibrosis and remodeling of blood vessels. Fibrosis involves the excessive accumulation of collagen and other extracellular matrix components, which stiffen blood vessels and reduce their elasticity. This stiffening contributes to increased resistance to blood flow and higher blood pressure.
  4. Hypoxia: In some cases, parasitic infections can lead to tissue hypoxia, where there is a decrease in oxygen supply to tissues. Hypoxia triggers various adaptive responses in the body, including the constriction of blood vessels in affected tissues to redirect blood flow to more vital organs. This can result in increased systemic vascular resistance and elevated blood pressure.
  5. Endothelin-1: Endothelin-1 is a potent vasoconstrictor produced by endothelial cells. In conditions of parasitic infection, there may be an upregulation of endothelin-1 production, contributing to increased vascular tone and hypertension.
  6. Nitric Oxide (NO) Imbalance: Parasitic infections can disrupt the balance of nitric oxide (NO) in the body. NO is a vasodilator produced by endothelial cells that helps regulate blood pressure. Disruption of NO synthesis or function can lead to vasoconstriction and hypertension.
  7. Renin-Angiotensin System (RAS) Activation: The renin-angiotensin system plays a crucial role in regulating blood pressure. Parasitic infections can activate the RAS, leading to increased production of angiotensin II, a potent vasoconstrictor. Angiotensin II can also stimulate the release of aldosterone, leading to sodium and water retention, further contributing to hypertension.
  8. Oxidative Stress: Parasitic infections can induce oxidative stress in the host’s body, leading to the production of reactive oxygen species (ROS). ROS can damage blood vessels and impair their function, contributing to hypertension.

These are some of the biochemical mechanisms through which parasitic infections can lead to high blood pressure. It’s important to note that the specific mechanisms may vary depending on the parasite involved and the individual host response. Treatment typically involves addressing the underlying parasitic infection and managing hypertension through antihypertensive medications if necessary.

At Home Parasite Test | Can Parasites Cause High Blood Pressure?

Despite what you may think, you can order a parasite stool test at home. There are however other free tests you may be able to get at your doctor.

Just be aware, that tests don’t always detect all parasites. Therefore I usually recommend getting any and all free parasite tests that are covered by your doctor plus an at home parasite test, or if you are on a budget, just start with some anti parasitic foods or a parasite cleanse tincture, and analyze your poop for excreted parasites. If you consume a lot of pork or sushi, then you are at higher risk of very dangerous parasites, and should integrate preventative measures and frequent testing into your diet plan; in this case you may want to consult your doctor for parasitic medications. Just make sure you consult a good naturopathic doctor first.

The Best Parasite Cleanse?

The Amish and many other cultures use a parasite cleanse tincture that includes black walnut, cloves and wormwood; any good parasite cleanse should include these. I have used one with my clients and family with much success the Rogershood Parasite Cleanse; comes as a single tincture or a more comprehensive kit to support detox and parasite die off symptoms. You can also add anti-parasitic foods like garlic and pumpkin seeds, to name a few.

Need Help with Your Parasite Cleanse or High Blood Pressure?

Book a virtual appointment to work with a holistic nutritionist or nutritional counselor, for guidance and to ensure a safe and effective parasite cleanse. Although parasites may be a factor, there are many other things that can contribute to high blood pressure. I have experience and have worked with individuals to help lower their high blood pressure.

Conclusion | Can Parasites Cause High Blood Pressure

Yes, there are many ways parasites can contribute to high blood pressure. Now that you have the answer to can parasites cause high blood pressure…what are you going to do about it? You can get various parasite tests at your Dr. or an at-home stool test (or both). You can also begin a parasite detox and analyze your stool. There are excellent herbal parasite killer tinctures. But for those with significant symptoms they think might be connected to parasites, or high blood pressure they may want to consult their doctor to get on stronger anti-parasitic medications and combined that with a supportive holistic protocol. You can even Book a virtual appointment for expert guidance on parasites and detoxing them but always consult your doctor with any recommendations you receive.
