Feeling exhausted even after a full night's sleep? Becoming short of breath climbing stairs that never used to challenge you? Perhaps you've recently had blood work showing a low red blood cell count or low hemoglobin and you're wondering what it means.
Anemia is one of the most common medical conditions worldwide, affecting people of all ages. While fatigue is often the symptom that brings people to the doctor's office, anemia can affect nearly every organ in the body because it reduces the blood's ability to deliver oxygen where it's needed most.
As a licensed Naturopathic Doctor practicing in Ontario for nearly twenty years, I've found that one of the most important aspects of caring for patients with anemia is understanding why it developed. Anemia itself is not a diagnosis it is a sign that something else may be affecting your health.
Rather than focusing only on improving blood counts, it's important to identify the underlying cause of anemia so that appropriate treatment can be directed at both the symptoms and the source of the problem.
What is Anemia?
One of the first questions patients ask is: What is anemia?
Anemia occurs when there are not enough healthy red blood cells or when there is insufficient hemoglobin within those cells to carry oxygen efficiently throughout the body. Red blood cells transport oxygen from the lungs to tissues and organs. When the number of red blood cells falls or when hemoglobin levels become too low the body's tissues receive less oxygen, leading to many of the common anemia symptoms. Anemia can range from mild and temporary to severe and chronic, depending on its underlying cause.
What Does Low Red Blood Cell Count Mean?
Many laboratory reports identify a low red blood cell count, sometimes written as RBC low or noted on a low RBC blood test. If you need further evaluation, comprehensive blood test services can help identify the underlying cause and guide appropriate treatment.
What does low red blood cell count mean? It simply means there are fewer circulating red blood cells than expected. A low blood count does not tell us why anemia is present it simply tells us that further investigation is needed to determine the cause.
Healthcare providers also evaluate:
- Hemoglobin
- Hematocrit
- Mean corpuscular volume (MCV)
- Ferritin
- Vitamin B12
- Folate
- Reticulocyte count
Together, these tests help determine the specific type of anemia.

Iron deficiency is the leading cause of anemia globally, but other causes of anemia include vitamin B12 or folate deficiency, chronic kidney disease, chronic inflammation and blood loss. A low RBC blood test or low hemoglobin symptoms should always be evaluated to determine the underlying cause of anemia.
What Are the Symptoms of Anemia?
The symptoms of anemia often develop gradually and may initially be mistaken for stress, aging, or poor sleep.
Common anemia symptoms include:
- Persistent fatigue
- Weakness
- Shortness of breath
- Dizziness
- Pale skin
- Cold hands and feet
- Rapid heartbeat
- Headaches
- Difficulty concentrating
- Reduced exercise tolerance
These symptoms occur because the body's tissues are receiving less oxygen than they require.
Low Hemoglobin Symptoms
Many people specifically ask about low hemoglobin symptoms. Hemoglobin is the oxygen-carrying protein found inside red blood cells.
When hemoglobin levels decline, common symptoms of low hemoglobin include:
- Extreme fatigue
- Reduced stamina
- Lightheadedness
- Shortness of breath with activity
- Chest discomfort
- Palpitations
- Brain fog
The severity of symptoms often depends on how quickly anemia develops.
Symptoms of Anemia in Women
Women are more likely to develop anemia because of menstrual blood loss and the increased iron requirements of pregnancy.
Common symptoms of anemia in women include:
- Heavy menstrual periods
- Fatigue
- Hair thinning
- Dizziness
- Cold intolerance
- Poor concentration
- Reduced exercise capacity
Persistent heavy menstrual bleeding should always be evaluated rather than simply accepted as normal.
Causes of Anemia
One of the most important questions is: What is the main cause of anemia? There is no single answer.
The causes of anemia can generally be grouped into three categories:
1. Blood Loss
The most common cause of anemia worldwide is blood loss.
Examples include:
- Heavy menstrual bleeding
- Gastrointestinal bleeding
- Stomach ulcers
- Colon polyps
- Hemorrhoids
- Surgery
- Trauma
2. Reduced Red Blood Cell Production
The body may not produce enough red blood cells because of:
- Iron deficiency
- Vitamin B12 deficiency
- Folate deficiency
- Chronic kidney disease
- Chronic inflammatory diseases
- Bone marrow disorders
3. Increased Red Blood Cell Destruction
Some medical conditions cause red blood cells to break down more rapidly than they can be replaced.
Examples include:
- Autoimmune diseases
- Inherited blood disorders
- Certain infections
- Some medications
Determining which mechanism is responsible is essential for selecting the appropriate treatment.
Types of Anemia
There are many types of anemia, including:
- Iron deficiency anemia
- Vitamin B12 deficiency anemia
- Folate deficiency anemia
- Anemia of chronic disease
- Hemolytic anemia
- Aplastic anemia
- Sickle cell disease
- Thalassemia
Each type has different underlying causes and requires a different diagnostic approach.
What Causes Low Red Blood Cell Count?
Many patients wonder: What causes low red blood cell count? A low RBC count may result from:
- Blood loss
- Nutrient deficiencies
- Chronic illness
- Kidney disease
- Bone marrow disorders
- Autoimmune disease
- Certain medications
Because there are many possibilities, a comprehensive medical assessment is important.
Is Anemia Dangerous?
Is anemia dangerous? Mild anemia may cause relatively few symptoms. However, severe anemia can become a serious medical condition if left untreated.
Potential complications include:
- Significant fatigue
- Reduced physical performance
- Heart strain
- Pregnancy complications
- Cognitive difficulties
- Reduced quality of life
People with severe symptoms or rapidly developing anemia should seek prompt medical attention.
What Will Happen If You Are Anemic?
Without enough healthy red blood cells, every organ receives less oxygen than it needs.
Over time this may lead to:
- Chronic fatigue
- Poor concentration
- Reduced exercise capacity
- Shortness of breath
- Increased workload on the heart
In severe cases, prolonged oxygen deprivation may contribute to cardiovascular complications, particularly in people with existing heart disease.
Which Organ Is Most Affected by Anemia?
Although anemia affects the entire body, the heart is often one of the organs most affected. To compensate for reduced oxygen delivery, the heart must pump harder and faster. The brain and muscles are also particularly sensitive to reduced oxygen, explaining why many people experience fatigue, dizziness and difficulty concentrating.

A low red blood cell count reduces the body's ability to deliver oxygen to tissues, which can affect the heart, brain and muscles. Symptoms of anemia in women are especially common during the reproductive years due to menstrual blood loss, making early assessment and appropriate investigation important.
How Do You Fix Anemia?
Patients commonly ask: How do you fix anemia?
The answer depends entirely on identifying the underlying cause. Treatment may involve addressing nutritional deficiencies, treating blood loss, managing chronic disease, or investigating other medical conditions affecting red blood cell production. Simply increasing iron intake is not appropriate for every type of anemia, which is why an accurate diagnosis is essential before treatment begins.
The Role of a Naturopathic Doctor
As Naturopathic Doctors, we are trained as primary healthcare professionals to evaluate both the symptoms and the underlying causes of illness. When assessing anemia, we take a comprehensive approach that includes reviewing nutrition, digestive health, menstrual history, medications, chronic health conditions and lifestyle factors that may contribute to low blood counts. Because we spend considerable time listening to our patients, we are often able to identify patterns that help guide further investigation. We also work collaboratively with family physicians, hematologists and other healthcare professionals when additional testing or specialist care is needed. Our goal is not simply to improve laboratory values but to understand why anemia developed and support long-term health through individualized, evidence-informed care.
When Should You Seek Medical Attention?
You should seek medical assessment if you experience:
- Persistent fatigue
- Shortness of breath
- Chest pain
- Dizziness or fainting
- A newly identified low red blood cell count
- Heavy menstrual bleeding
- Blood in the stool or urine
- Rapidly worsening symptoms
Prompt diagnosis helps identify the underlying cause and prevents complications.
Persistent fatigue, weakness, dizziness, or shortness of breath may be signs of anemia and should not be overlooked. Identifying the underlying cause is essential for restoring healthy red blood cell levels, improving your energy and supporting your long-term health. Early evaluation and personalized care can make a meaningful difference in how you feel every day.
