During the early 20th century, coal miners put their lives at risk while working in dangerous conditions. The saying “canary in the coal mine” came from this time period and meant a warning of possible peril or sign of an impending threat. Miners would bring a canary into the mine with them. Canaries were much more sensitive to carbon monoxide than humans and would exhibit signs of distress or even die if exposed to high levels of carbon monoxide. In either case, the miners knew to evacuate immediately, as hazardous gases were likely present.

As it’s used now, the phrase “canary in the coal mine” describes something that signals an impending problem or shines a light on a hidden issue which was undetected.

Your high blood pressure is the same as the canary because it indicates a problem with the kidneys. Kidneys are used to regulate fluid volume and salt levels in the body. MDs have declared that “salt sensitivity” is the reason some people have issues when they consume salt. 30-50% of hypertensive patients are considered “salt sensitive.” Based on what I’ve seen in practice, it seems there is a relationship between neuropathy and hypertension and many of the patients who have come to our office for neuropathy had hypertension but were NOT yet taking medications for diabetes.

  1. Kidney’s Role in Blood Pressure Regulation: A Simple Explanation

Our kidneys play a crucial part in managing our blood pressure, ensuring our bodies function smoothly. They do this through a delicate balance of several processes, all working together to keep our blood pressure in check. Let’s break it down into simpler terms.

  1. Keeping the right amount of fluid and blood flow

Firstly, the kidneys regulate the volume of fluid outside our cells, as well as the flow of blood to the kidneys themselves. These factors are vital for maintaining a stable blood pressure level, which helps keep our bodies healthy.

  1. The role of pressure natriuresis and special hormone systems

The kidneys also control sodium excretion through a process called pressure natriuresis. This process is directly influenced by the blood pressure in our renal arteries. Additionally, our kidneys affect the activity of several hormone systems, such as the renin-angiotensin-aldosterone system, which helps regulate our blood pressure.

  1. Kidney disorders and high blood pressure

Sometimes, health problems can affect our kidneys or the blood vessels supplying them, leading to secondary forms of high blood pressure. It’s important to recognize and manage these issues to prevent further complications.

  1. Special kidney cells and their role in blood pressure control

Our kidneys contain unique cells called juxtaglomerular cells. These cells are like natural barometers that constantly monitor our blood pressure. When our blood pressure drops too low, these cells release a hormone called renin, signaling our body to raise the blood pressure back to a normal range.

In summary, our kidneys play a vital role in regulating our blood pressure through a combination of fluid management, sodium excretion, hormone systems, and specialized cells. It’s crucial to maintain good kidney health to ensure our bodies function efficiently and effectively.

  1. Blood Pressure Maintenance Mechanisms: A Layperson’s Guide

To keep our blood pressure stable, our bodies use several mechanisms. Let’s explore these in simpler terms, focusing on how the kidneys play a part in this intricate balancing act. Your kidneys manage sodium and water levels to maintain the correct blood pressure levels.

The nephron’s role in reabsorbing vital substances

Within our kidneys, tiny units called nephrons work tirelessly to regulate the amount of sodium and water absorbed by our body. When our blood pressure drops, these nephrons increase sodium and water reabsorption, ultimately raising our blood pressure.

The importance of staying within the normal range

Low blood pressure can be a significant risk factor for chronic kidney failure. That’s why it’s essential to keep our blood pressure as close to normal as possible, ensuring our kidneys function optimally and protecting our overall health.

  1. The autonomic nervous system and pressure-sensitive receptors

Detecting changes in blood pressure

Our bodies have a built-in system to detect changes in blood pressure, known as the autonomic nervous system (ANS). This system works closely with pressure-sensitive receptors, called baroreceptors, which can sense fluctuations in blood pressure.

Baroreceptors in action

Baroreceptors are located in strategic areas, such as the arch of the aorta and the carotid sinus. When blood vessels stretch due to changes in blood pressure, these receptors are activated. In response, they send signals to the ANS, which then adjusts blood pressure accordingly.

In a nutshell, our kidneys and the autonomic nervous system work hand-in-hand to maintain blood pressure within a healthy range. They do this by regulating sodium and water levels in our bodies and using specialized receptors to detect and respond to changes in blood pressure. These mechanisms are vital for our overall health and well-being. In individuals with conditions like diabetes and neuropathy, effectively managing blood pressure becomes even more critical. By understanding the essential role kidneys play in blood pressure regulation and adopting healthy lifestyle habits, we can reduce the risk of complications such as heart disease, stroke, and kidney damage. As a result, it’s crucial to monitor and control blood pressure, especially in those with pre-existing health conditions, to ensure a healthier and happier life.

III. Blood Pressure Control and Treatment Options: An Easy-to-Understand Overview

Controlling blood pressure is essential for our well-being. Here, we’ll discuss the importance of blood pressure management and various treatment options in plain language.

Peripheral artery disease patients

For those with peripheral artery disease (PAD), managing blood pressure is critical to reducing the risk of cardiovascular disease. Regular blood pressure checks are vital to ensure the best possible health outcomes for PAD patients.

The benefits of intensive blood pressure control

Researchers have found that strict blood pressure control has a positive impact on individuals who require frequent hemodialysis (HD). Observational studies and randomized trials support the effectiveness of intensive blood pressure management.

  1. Antihypertensive medications and preferred treatments


Several medications can help lower blood pressure, including ACE inhibitors and angiotensin II receptor blockers (ARBs). These drugs are often considered the first line of defense in treating high blood pressure BUT should only be used long enough to allow time to implement lifestyle changes which will decrease your blood pressure. Medications should NOT be used a long-term method if you want to remain healthy.

Lifestyle changes and pharmacotherapy

For people with blood pressure higher than 140/90 mmHg, pharmacotherapy can be combined with lifestyle changes to control blood pressure effectively. Keeping blood pressure in check is crucial for preventing complications related to diabetes and kidney disease. The best way to manage blood pressure is to improve eating habits, exercise and practice stress reduction because even “controlled” blood pressure can lead to problems over time. Our office provide programs related to neuropathy and nutrition education which can help you achieve this goal.

The impact of diabetes on blood pressure and kidney function

Diabetes can lead to higher blood pressure levels compared to kidney disease alone. It’s essential to manage blood pressure to avoid further complications. In most cases, ACE inhibitors and ARBs are recommended for blood pressure management in diabetic patients. Although effective in lowering blood pressure, they are only “patch solutions” which will allow other disease processes to progress (diabetes, CV damage, neuropathy).

Controlling blood pressure is a crucial aspect of maintaining our health and various mechanisms, medications, and treatments are available to help manage blood pressure in different situations, including kidney disease and diabetes. Being proactive about your lifestyle choices and managing blood pressure through diet, nutrition and exercise are THE most effective means of preventing heart disease, stroke, and other associated complications like neuropathy.

The Medical Industry views high blood pressure as a problem that can be solved with medication without looking any further. Don’t ignore the Canary in the Coal mine.
