Understanding the function of hemoglobin and its normal levels in the body

Hemoglobin or Hb is a protein found in red blood cells. This protein is what makes blood red. In normal levels, hemoglobin has many functions for the body. Therefore, it is necessary to maintain a normal level of hemoglobin at all times

Besides giving color, hemoglobin also functions to help red blood cells get their natural shape, which is round with a flatter center. With this shape, red blood cells can easily move and flow in the blood vessels.

If the amount or form of hemoglobin is abnormal, red blood cells cannot function properly in transporting oxygen and carbon dioxide. This can trigger various he alth problems, including anemia.

Instruction of Hemoglobin Level

The normal value of hemoglobin levels in a person's body is determined by gender and age. Normal hemoglobin levels in adult women range from 12–15 g/dL, while hemoglobin levels in adult men range from 13–17 g/dL.

When a person's hemoglobin condition is higher or lower than the normal amount, this can be a sign of a he alth problem. The following are some of the causes and symptoms of abnormalities in hemoglobin:

Low hemoglobin level

Low hemoglobin levels indicate that the body is anemic. Some causes of low Hb, such as blood loss, impaired kidney and bone marrow function, radiation exposure, or lack of nutrients such as iron, folate, and vitamin B12.

When hemoglobin cannot function properly, the body will experience several symptoms such as weakness and fatigue, headaches and dizziness, pale skin, chest palpitations, and shortness of breath.

Low hemoglobin can be treated by addressing the underlying cause.

In addition, to increase the amount and function of hemoglobin, people with Hb deficiency can also take blood-boosting drugs or foods rich in iron, folate, and vitamin B12, such as meat, fish, eggs, and vegetables.

There is a genetic disorder that interferes with the formation of hemoglobin in red blood cells. This disease is known as porphyria.

High hemoglobin level

Hemoglobin levels that are too high also indicate a he alth problem in the body. Conditions of high hemoglobin levels can be caused by polycythemia vera, cancer, kidney tumors, lung disease, congenital heart defects, and dehydration.

In addition, smoking habits, side effects of certain drugs, as well as environmental factors such as living in a highland area or a workplace that is at risk of causing carbon monoxide poisoning, can also trigger an increase in hemoglobin levels.

A person with a high hemoglobin level can experience several symptoms, such as headaches, dizziness, and weakness, but sometimes there are no symptoms. High hemoglobin levels are not always dangerous, but some studies suggest that this condition can increase the risk of cardiovascular diseases such as stroke and heart attack.

Benefits of Checking Hemoglobin Levels

Hemoglobin levels can be known through blood tests. Doctors will usually advise patients to undergo blood tests to evaluate their hemoglobin levels.

Hemoglobin level checks are also often done for certain purposes, including:

Diagnosing a disease

There are several diseases that can be diagnosed by doing a hemoglobin test, such as anemia or polycythemia. These two diseases often do not cause typical symptoms and are only detected through a medical examination by a doctor, including blood tests to assess hemoglobin levels.

Monitoring he alth conditions

If you have certain diseases, especially diseases related to blood, the doctor will do a hemoglobin test to monitor your medical condition.

In addition, hemoglobin examination can be used as a tool to monitor your condition and the success of the treatment given, as well as determine the right type of treatment until you recover from the disease.

Regular he alth check

Hemoglobin checks are also often carried out during routine medical check-ups.This hemoglobin test is part of a complete blood count series. The goal is to determine whether or not there are conditions that require special attention, such as anemia.

The function of hemoglobin is very important for the body. If the hemoglobin count is too low or too high, it can cause various he alth problems. To evaluate your hemoglobin level and your body's he alth condition, you can consult an internal medicine doctor.
