What Does It Mean To Have High Hemoglobin And Hematocrit – Hemoglobin is a metalloprotein in red blood cells. It contains iron and is responsible for carrying oxygen from the lungs to the rest of the body. Measuring hemoglobin levels allows healthcare professionals to monitor many other aspects of a person’s health, including finding hidden conditions.
Healthcare workers can use a few different methods to measure hemoglobin levels. It is usually necessary to take a blood sample and analyze the hemoglobin concentration in it.

What Does It Mean To Have High Hemoglobin And Hematocrit
Recently, a non-invasive method called pulse CO-oximetry has been able to provide continuous hemoglobin counts with accuracy equal to more invasive options. Because hemoglobin is a component of red blood cells, hemoglobin tests also provide an indirect measure of red blood cell counts.

Hemoglobin tests are needed for many reasons. To monitor general health, a healthcare worker may test hemoglobin levels as part of a complete blood count during a routine checkup. A doctor can also use hemoglobin levels to diagnose an illness if the patient has other symptoms. Hemoglobin tests also allow continuous monitoring of an existing medical condition.
When determining whether a patient has a normal hemoglobin level, experts also consider factors such as height when testing their blood.
High hemoglobin levels are rarer than low concentrations and are often asymptomatic. Usually, a doctor detects high hemoglobin levels only by chance or after symptoms of an underlying condition emerge.
Most conditions that cause this symptom decrease the level of oxygen in the blood, causing hypoxia. In response, the body produces more hemoglobin.
Hemoglobin Level Is Positively Associated With Blood Pressure In A Large Cohort Of Healthy Individuals
A high hemoglobin count can be caused by an underlying condition, a side effect of a medication, or certain lifestyle choices. Some medical conditions that can cause high hemoglobin levels are heart disease, lung diseases such as COPD, dehydration and exposure to carbon monoxide.
Smoking cigarettes or taking anabolic steroids can also increase hemoglobin levels. People living at high altitudes also tend to have higher hemoglobin counts.
Abnormally low hemoglobin levels usually indicate a condition called anemia. In general, anemia means the body is unable to make enough healthy red blood cells or is severely deficient in hemoglobin, preventing oxygen transport. Mild anemia is typical at certain stages of life and during events such as pregnancy.
Unlike high hemoglobin levels, low concentrations are likely to be symptomatic. Since anemia is a sign of serious illness, these symptoms also indicate the need for medical intervention.

Symptoms of anemia include weakness, fatigue, pale skin, feeling cold, difficulty breathing, dizziness, headache and irregular heartbeat.
A person may have a low hemoglobin count if a condition such as cancer, cirrhosis, or rheumatoid arthritis prevents the body from producing enough red blood cells. In some cases, a disease actively destroys red blood cells. The culprits are usually sickle cell anemia or an enlarged spleen.
Hemoglobin levels may also be low if significant blood loss has occurred through open trauma, internal bleeding, or frequent blood donation. In some cases, heavy menstrual bleeding can cause anemia.
To treat high hemoglobin levels, the doctor often prescribes medication. If necessary, a health professional may prescribe phlebotomy, which regularly drains a safe amount of blood from the body until their hemoglobin levels return to a healthy concentration. Treating low hemoglobin levels requires addressing the underlying problem. Some people only need iron supplements, while others need more complex treatment.
What Type Of Cancer Causes Low Hemoglobin
A doctor may test for glycated hemoglobin, also known as hemoglobin A1c or HbA1c. This compound is formed when red blood cells combine with glucose in the blood. Monitoring hemoglobin A1c gives healthcare professionals a snapshot of their patients’ overall glucose levels over several weeks. High A1c levels indicate a higher risk of developing certain diabetes-related complications, so monitoring is an integral part of health for many people.

Here are the seventeen most common reasons why you may have elevated hemoglobin levels.
A high hemoglobin count confirms that your blood has a higher-than-average concentration of the oxygen-carrying compound hemoglobin. This is not the same as being high
, because red blood cells contain different types of hemoglobin. This is also not the same as high iron levels.
Rbc Blood Test: Normal Ranges And Diagnostic Uses
Iron levels may be high due to hereditary hemochromatosis or beta-thalassemia, but at the same time hemoglobin levels may be low due to red blood cell anemia. But it is also possible to have high hemoglobin levels even with anemia .
Red blood cells bound to sugar groups. You may have a high HbA1C count but still have low hemoglobin levels because you have both diabetes and anemia. And diabetics have artificially high HbA1C numbers because they have low hemoglobin or low red blood cell counts.
. Hematocrit is the ratio of the size of red blood cells to the total volume of blood. Because not all red blood cells contain the same amount of hemoglobin, a hematocrit does not tell you how much hemoglobin you have.
In the United States, most physicians define high hemoglobin counts as greater than 17.5 grams per deciliter (dL) of blood for men or greater than 15.5 g/dL for menstruating women. Low, normal, and high hemoglobin levels for children vary by age and gender.
What Is A Healthy Hemoglobin Level?
Most of the world measures hemoglobin in millimoles (mmol) per liter (L) instead. Hemoglobin levels in mmol/L are much lower than hemoglobin levels in g/dl. Outside the United States, “normal” hemoglobin values range from 9.6 mmol/L for women to 10.9 mmol/L for men. Children have higher hemoglobin levels than older children and adults.
Much of the data that led to the current understanding of “average” hemoglobin levels originally came from studies of blood donors who were rejected for donation if their hemoglobin levels were too low. 
There are no circumstances in which a doctor would order a hemoglobin test based on a hunch, such as “I wonder if this patient has high hemoglobin.” Hemoglobin measurements come in the context of a complete blood count (CBC), also known as a complete blood count (WBC) panel. High values of hemoglobin – along with other symptoms – confirm the diagnosis, but there are cases where the high hemoglobin level is not due to disease.
There are also health problems that can cause high hemoglobin levels. The most common of these, as well as the most dangerous
Pernicious Anemia: Definition, Symptoms, Causes & Treatment
. Cigarette smoke contains carbon monoxide, which binds to hemoglobin. The body produces more hemoglobin to replace the hemoglobin in the bloodstream, but it can no longer carry oxygen.  It takes about three months for hemoglobin levels to return to normal after you quit smoking .
Remember, elevated hemoglobin is always a symptom, never a disease. However, changes in your hemoglobin lab results are often an important indicator of your progress in regaining health, and hemoglobin results can also play a role in the diagnostic process. Hemoglobin is a protein found in your blood cells. It plays a vital role in carrying oxygen in the blood to all parts of the body. A sudden change in hemoglobin count can indicate health problems.
A low hemoglobin count may indicate anemia, a high count may indicate a health problem, or may be the result of lifestyle choices.
Hemoglobin is a protein found in your blood. Due to the presence of iron, hemoglobin gives blood its red color. Measuring hemoglobin levels in your blood gives an indirect idea of your red blood cell count. A normal hemoglobin count is between 14 to 17 grams per deciliter for men and 12 to 15 grams per deciliter for women. A complete blood count (CBC) test measures the number of blood cells and hemoglobin level. A high hemoglobin count is seen in routine CBC tests.

If you experience any of the above symptoms, it is best to consult a doctor to avoid further complications.
Hemoglobin count can vary throughout the day. Many factors such as age, gender, and health conditions can change the hemoglobin count in your blood.
A high hemoglobin count is a result of your body’s increased need to carry oxygen to different body parts. Certain lifestyle factors or some rare diseases can cause a high hemoglobin count, for example:
A number of reasons can cause a change in hemoglobin count. These changes can be reversed if you make the following lifestyle changes:

Medicines: A doctor may prescribe medicines to increase your hemoglobin levels. The course of treatment will largely depend on the underlying health problems that caused the change in your hemoglobin count.
Phlebotomy: In this treatment option, the doctor uses needles or syringes to remove blood from your body. This process may be repeated depending on your hemoglobin count.
