What is the normal value of hemoglobin considered anemia

The normal value of hemoglobin varies among different populations, with adult males below 120g/L and females below 110g/L being diagnosed with anemia. The judgment criteria are mainly related to gender, age, and physiological status.

1. Adult males:

The normal range of hemoglobin in healthy adult males is 120-160g/L. When the detection value remains below 120g/L, it indicates anemia, which is commonly seen in iron deficiency anemia, chronic disease anemia, etc. Mild anemia may only manifest as fatigue, while severe anemia may present symptoms such as palpitations and pale complexion.

2. Adult women:

The normal value for non pregnant women is 110-150g/L, and a value below 110g/L is considered anemia. Women are more prone to iron deficiency anemia due to the influence of their menstrual cycle, and the pregnancy standard will be further lowered to 100g/L. Long term anemia may lead to symptoms such as lack of concentration and chills.

3. Children's population:

The normal value of hemoglobin in newborns is the highest at 170-200g/L, not less than 110g/L for children aged 6 months to 6 years, and not less than 120g/L for children aged 6-14 years. Childhood anemia may affect growth and development, and special attention should be paid to nutritional anemia caused by picky eating, infections, and other factors.

4. Elderly:

The standard for people over 65 years old can be appropriately relaxed, but it should still not be lower than 110g/L for males and 105g/L for females. Anemia in the elderly is often associated with chronic diseases and malnutrition, which may increase cardiovascular burden. It is necessary to investigate hidden causes such as gastrointestinal bleeding.

5. Special physiological period:

Pregnant women with hemoglobin levels below 100g/L can be diagnosed with anemia, and the standard for residents in high-altitude areas needs to be increased by 10-20g/L. Long term smokers may experience a false increase in test values due to the influence of carbon monoxide, and it is necessary to make a comprehensive judgment based on other indicators.

To prevent anemia, it is necessary to ensure the intake of iron, folate, and vitamin B12 in the diet. Animal liver, red meat, and dark green vegetables are all high-quality sources. It is recommended that women of childbearing age undergo regular blood routine tests, and elderly people pay attention to changes in hemoglobin levels during annual physical examinations. Mild anemia can be improved through dietary adjustments, while moderate to severe anemia or other accompanying symptoms should be promptly treated with medical attention and targeted treatment after identifying the cause. For those who experience significant shortness of breath or dizziness during exercise, it is recommended to pause vigorous activity and have their blood routine rechecked.
