Hematocrit Levels (Male)

What Causes Abnormal Hematocrit Levels In Men?

In order to deal properly with abnormal hematocrit levels in men we need to understand and — if possible — remove the underlying causes and risk factors.  We need to ask: "What else is going on inside the body that might allow abnormal hematocrit levels in men to develop?"

Accurate diagnosis of the factors behind abnormal hematocrit levels in men consists of three steps:

Step 1: List the Possible Causative Factors

Identify all disease conditions, lifestyle choices and environmental risk factors that can lead to abnormal hematocrit levels in men.  Here are five possibilities:
  • Bone Marrow Suppression
  • Anemia
  • Non-Hodgkin's Lymphoma
  • Chronic Renal Insufficiency
  • Leukemia

Step 2: Build a Symptom Checklist

Identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
blood clotting problems
low red blood cell count
moderate unexplained weight loss
weak appetite
slightly elevated eosinophil count
occasional unexplained fevers
low hemoglobin levels
severe fatigue after slight exertion
regular unexplained nausea
easily becoming short of breath
slight diffuse bone pain
frequent infections
... and more than 30 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of abnormal hematocrit levels in men:
Cause Probability Status
Non-Hodgkin's Lymphoma 99% Confirm
Anemia 25% Unlikely
Chronic Renal Insufficiency 0% Ruled out
Leukemia 0% Ruled out
Bone Marrow Suppression 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate having had recent lab tests, The Analyst™ will ask further questions including this one:
Hematocrit (HCT). Unit: Percent [fraction]
Possible responses:
→ Don't know
→ Under 30% [0.30]
→ 30 to 40% [0.30-0.40]
→ 41 to 51% [0.41-0.51] (normal)
→ Over 51% [0.51]
Based on your response to this question, which may indicate very low hematocrit, low hematocrit, normal hematocrit or high hematocrit, The Analyst™ will consider possibilities such as:
Anemia
Anemia also suggests the following possibilities:
Chronic Renal Insufficiency
Anemia is almost always present in cases of chronic renal failure, and can occur through any of the basic mechanisms (blood loss, excessive destruction of red blood cells, or low production of red blood cells.) However, the typical anemia associated with CRF results from decreased production of red blood cells by the bone marrow: failing kidneys no longer produce sufficient erythropoietin, a hormone that stimulates the production of oxygen-carrying red blood cells (RBCs).  In addition to decreased levels of RBCs, patients often begin to accumulate toxic metabolites, which shorten the lifespan of existing RBCs.
Leukemia
The red blood cell deficiency caused by leukemia leads to anemia and the symptoms of anemia, including severe fatigue, pallor, and breathing difficulty.
