Understanding High Red Blood Cell Count
The term "high red blood cell count" is both self-explanatory and critical for you to understand. If you're studying nursing, you will frequently encounter such terms.
A high red blood cell count, also called erythrocytosis or polycythemia, refers to the state when your body is producing more red blood cells than normal. Red blood cells, or erythrocytes, are cells in your bloodstream responsible for delivering oxygen to your body. The high production might be a reaction to various conditions or it could be a disorder in itself.
Red blood cells, besides carrying oxygen, also remove carbon dioxide from your body, transporting it to the lungs for you to exhale. They're created in your bone marrow—the soft, spongy tissue inside your bones. A primary hormone, erythropoietin (EPO), regulates the production of red blood cells. When you explore a high red blood cell count, it's important to understand what usual levels look like. For men, a count of 4.7 to 6.1 million red blood cells per microliter (mcL) of blood is normal, while for women, it's 4.2 to 5.4 million mcL.
Main Causes of High Red Blood Cell Count
There are several causes for a high red blood cell count. These can generally be categorised into primary and secondary factors.
- Primary factors: These are generally genetic and result in the bone marrow producing too many red blood cells. This condition is known as polycythemia vera.
- Secondary factors: These are a response to external circumstances, such as low oxygen levels, an EPO-producing tumour, or performance-enhancing drugs.
| Primary factors | Polycythemia vera |
| Secondary factors | Low oxygen levels |
| EPO-producing tumour | |
| Performance-enhancing drugs |
For instance, someone who spends a lot of time at high altitudes, where the air is thinner and oxygen levels are lower, might naturally produce more red blood cells to compensate for the decreased oxygen. This is a secondary response. But if they had polycythemia vera, their body would be making excessive red blood cells regardless.
Explanation: What does High Red Blood Cell Count Mean?
A high red blood cell count can mean different things depending on the circumstances, but its primary implication is on the blood's thickness.
When there are too many red blood cells in the blood, it can thicken, making it harder for your blood to flow through vessels and organs. If blood flow is disrupted or slow, this could starve your body of the oxygen it needs. This blood thickening, known as polycythemia, can lead to other health issues like blood clots and heart attacks.
A high red blood cell count can also indicate a condition such as lung disease or a problem with the heart's right ventricle. These conditions can make the body produce more red blood cells in an attempt to compensate for the decreased oxygen levels. If you're studying nursing, you'll learn to view a high red blood cell count as a sign that something might be wrong—it's usually a symptom rather than a disease in itself.
Symptoms of High Red Blood Cell Count
You'd naturally be curious about the effect of having a high red blood cell count. Understandably, you may want to know what signs and symptoms to look out for, particularly if you're in a nursing role.
Recognising Signs and Symptoms of High Red Blood Cell Count
As a fledgling nurse, it's important to master the ability to identify and interpret various symptoms. A high red blood cell count can lead to several noticeable symptoms, especially as the blood thickens and impedes the flow of oxygen.
The most common symptoms include:
- Headaches
- Fatigue or weakness
- Shortness of breath
- Chest pain
- Dizziness, light-headedness, or fainting
| Headaches |
| Fatigue or weakness |
| Shortness of breath |
| Chest pain |
| Dizziness, light-headedness, or fainting |
These symptoms occur because thicker blood flows more slowly, which means that less oxygen is delivered to the brain and muscles. It could also result in blockages that prevent blood flow entirely. For example, a stroke might occur if blood cannot reach the brain, while a heart attack might happen if blood cannot reach the heart.
Consider a marathon runner who lives at high altitudes. Due to the lower oxygen levels, their body produces more red blood cells, and they might frequently experience symptoms such as shortness of breath and headaches. This is due to the increased number of red blood cells in their body.
Beyond these typical symptoms, there are other, less common signs that could also point to a high red blood cell count. For instance, you might notice more subtle symptoms such as:
- Itchy skin, particularly after a shower or bath
- Ringing in the ears (tinnitus)
- Bone pain
- Unexplained weight loss
- Blurred vision
Knowing how to spot and interpret these symptoms can help you understand the clinical picture behind a high red blood cell count.
High Red Blood Cell Count Treatment Options
Understanding the realm of treatment options available for patients with high red blood cell count, is a critical part of your nursing education. There's a range of approaches to mitigating this condition, typically depending on the underlying cause, the person's overall health, and the specific symptoms exhibited. Let's delve into these treatment methods.
Overview of Potential Treatments for High Red Blood Cell Count
It's essential to tackle a high red blood cell count. The choice of treatments can vary widely depending on the cause of the condition, and they can include pharmaceutical methods, lifestyle changes, and particular procedures.
Here's an overview of potential treatments, which may be used alone or in combination:
- Medication: This might include low-dose aspirin to prevent blood clots, or medication that suppresses the body's production of red blood cells
- Lifestyle changes: These can include increased hydration, low-intensity exercises, and adjustment to living at low altitudes
- Phlebotomy: This procedure, also known as venesection, involves removing blood from the body to decrease the red blood cell count
| Medication | Low-dose aspirin, red blood cell suppressors |
| Lifestyle changes | Increased hydration, low-intensity exercises, altitude adjustment |
| Phlebotomy | Blood removal to decrease red blood cell count |
Other treatments can target the underlying causes of the high red blood cell count. For example, for patients whose erythrocytosis is caused by tumours producing excess erythropoietin, treating the tumour can resolve the high red blood cell count.
Consider a patient who has been using erythropoietin-stimulating performance-enhancing drugs, leading to a high red blood cell count. Their treatment might include educating them about the risks of these substances and helping them find safer alternative methods to enhance athletic performance. They might also need medication to reduce their red blood cell count and prevent blood clots.
Medical Steps in Managing High Red Blood Cell Count
From a medical perspective, managing high red blood cell count involves a step-by-step approach.
Here's a guide to the typical medical steps involved:
- Diagnosis: This first step will often involve a blood test to confirm the high red blood cell count. This may be followed by further tests to determine the cause.
- Treatment planning: Once the cause has been determined, the healthcare provider will work with the patient to develop a treatment plan. This will be customised according to the patient's needs and the underlying cause of the condition.
- Ongoing monitoring: The patient's red blood cell count will be regularly monitored to ensure the treatment is effective. The treatment plan may need adjustments over time.
| Diagnosis | Blood tests, additional tests for underlying causes |
| Treatment planning | Formulating customised treatment plan |
| Ongoing monitoring | Regular check-ups and necessary treatment adjustments |
The aim of this management process is not just to reduce the red blood cell count, but also to alleviate symptoms, prevent complications, and treat any underlying conditions causing the problem. Healthcare providers will work closely with patients throughout this process, providing support and guidance.
An individual who has recently been diagnosed with lung disease might also discover they have a high red blood cell count as a result of their body's response to decreased oxygen levels. Their medical management would likely involve not just treatment to reduce the high red blood cell count (perhaps through phlebotomy or medication), but also an ongoing management plan for their lung disease, tailored to their personal health circumstances.
High Red Blood Cell Count: A Link to Other Ailments
When studying nursing, it's indispensable to understand the expansive interconnections between different health conditions. An example of this is the potential link between a high red blood cell count and other ailments. In this context, one might commonly observe associated conditions such as cancer and diabetes.
High Red Blood Cell Count and Its Link to Cancer
It's essential to grasp how a high red blood cell count, or erythrocytosis, may be linked to specific cancers. This relationship revolves around the hormone erythropoietin (EPO), which stimulates red blood cell production.
Erythropoietin, or EPO, is primarily produced in the kidneys. It aids in the creation of red blood cells by the bone marrow. However, certain types of tumours also secrete EPO, leading to excessive red blood cell production.
Tumour-related erythrocytosis can be associated with various types of cancer, particularly renal (kidney) cell carcinoma, hepatocellular (liver) cancer, and certain types of ovarian cancer. If these cancers release EPO in substantial amounts, they might induce a condition called secondary erythrocytosis.
Suppose an individual is diagnosed with renal cell carcinoma, a type of kidney cancer. The tumour may result in elevated EPO levels, stimulating the bone marrow to produce more red blood cells. Consequently, they develop a high red blood cell count, resulting in symptoms like headaches, dizziness, and fatigue. This condition might lead health care providers to discover the underlying cancer.
The link between high red blood cell count and cancer underscores the value of comprehensive assessments when encountering high red blood cell counts in clinical settings.
Relationship Between High Red Blood Cell Count and Diabetes
Another condition potentially linked to a high red blood cell count is diabetes, particularly type 2 diabetes.
Diabetes type 2 is a chronic condition that affects how your body metabolises glucose (sugar). Prolonged high blood sugar levels can lead to various complications, including damage to blood vessels and nerves that control the heart and blood vessels.
There's a somewhat complex relationship between diabetes and the red blood cell count. In diabetes, particularly if poorly controlled, increased blood viscosity due to high glucose levels can lead to damage in the microcirculation. This damage can reduce tissue oxygenation and stimulate the production of erythropoietin, leading to an increase in the red blood cell count.
Imagine a person with poorly controlled type 2 diabetes. Over time, their persistent high blood sugar levels damage their smaller blood vessels, impairing oxygen delivery to their tissues. Their body responds by producing more EPO to stimulate red blood cell production, increasing their red blood cell count. They start experiencing symptoms like fatigue and breathlessness, which could potentially alert health care providers to their elevated red blood cell count.
While a high red blood cell count might seem like an isolated issue, it can often indicate or intertwine with other health issues, such as cancer or diabetes. Recognising such links is thus indispensable for a well-rounded understanding of patient health.
