Low hemoglobin count

Hemoglobin (Hb or Hgb) is a protein in red blood cells that transports oxygen throughout the body and transports carbon dioxide to the lungs for elimination. When a low hemoglobin count causes anemia, causing the organs not to receive enough oxygen, then you will feel tired and do not want to do anything.

1. Low Hemoglobin Count

Hemoglobin (Hb or Hgb) is a protein in red blood cells that transports oxygen throughout the body and carries carbon dioxide to the lungs for elimination.
A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter of blood (or less than 135 grams per liter of blood) for men and less than 12 grams per deciliter of blood (or less than 120 grams per liter). blood) for women. In children, the definition of low hemoglobin varies by age and sex. This threshold varies slightly among other medical facilities.
In many cases, a hemoglobin level that is only slightly lower than normal does not affect how you feel. A low hemoglobin count that gets worse and causes symptoms could mean you have anemia.

2. What causes low hemoglobin count?

A slightly low hemoglobin count is not always a sign of illness, it can be normal for some people. Menstruating women and pregnant women often have lower-than-normal hemoglobin counts.
A low hemoglobin count may be related to a disease or condition that causes your body to have too few red blood cells. This can happen if:
Your body produces fewer red blood cells than usual Your body destroys red blood cells faster than it is produced You lose blood Diseases and conditions that cause your body produces fewer red blood cells than usual including:
Non-regenerative anemia Cancer Certain medicines, such as antiretroviral drugs to treat HIV infection and chemotherapy drugs for cancer and other other disease. Chronic kidney disease Cirrhosis Hodgkin lymphoma (Hodgkin's disease) Hypothyroidism Inflammatory bowel disease (IBD) Iron deficiency anemia Lead poisoning Leukemia Multiple myeloma Non-Hodgkin lymphoma Non-Hodgkin lymphoma Rheumatoid arthritis Deficiency vitamin deficiency blood Diseases and conditions that cause your body to destroy red blood cells faster than it can make them include:
Enlarged spleen (enlarged spleen) Hemolysis Porphyria Sickle cell anemia Thalassemia No. Low hemoglobin can also be caused by blood loss, which can happen from:
Bleeding in your digestive tract, such as from ulcers, cancer or hemorrhoids. Donate blood regularly. Menorrhagia (heavy menstrual bleeding), sometimes even normal menstrual bleeding can cause a slightly low hemoglobin level.

3. What happens when the hemoglobin count is low?

If an illness or condition affects the body's production of red blood cells, hemoglobin levels may drop. Fewer red blood cells and lower hemoglobin levels can make you anemic.
Anemia is a blood disorder that occurs when there is not enough hemoglobin in a person's blood. There are several different types of anemia. Some types cause only mild health problems, while others are much more serious.
Anemia is caused by one of the following:
The body cannot make enough hemoglobin. The body makes hemoglobin, but hemoglobin does not work properly. The body does not make enough red blood cells. The body breaks down red blood cells too quickly. Your body uses iron to make hemoglobin. Iron deficiency in the body is the most common cause of anemia. This is called iron deficiency anemia. If you don't get enough iron, your body can't make hemoglobin. Factors that can decrease your body's iron stores include:
Blood loss: from ulcers, trauma, some cancers and other conditions; and, in women, during the monthly menstrual period. Iron-poor diet An increase in the body's iron requirements in women during pregnancy. There are several symptoms that occur with all types of anemia, including:
Feeling tired Shortness of breath Dizziness Headache Feeling cold Weakness Pale skin
Chóng mặt
Đau đầu, chóng măt là triệu chứng thường thấy ở tất cả các loại thiếu máu

4. Low hemoglobin count, when to see a doctor?

Some people learn that their hemoglobin is low when they try to donate blood. Being denied a blood donation is not necessarily a cause for concern. You may have the right hemoglobin count but not meet the standards set by the blood donation center.
If your hemoglobin count is only slightly below the required level, especially if you have been approved to donate blood before, you may just need to wait a few months and try again. If the problem persists, make an appointment to see your doctor.
If you have signs and symptoms of a low hemoglobin count, make an appointment with your doctor. Signs and symptoms of a low hemoglobin count may include:
Fatigue Weakness Pale skin and gums Loss of breath Fast or irregular heartbeat Your doctor may recommend a complete blood count test to confirm Determine if you have a low hemoglobin count. If testing shows you have a low hemoglobin count, you'll probably need further testing to determine the cause.
