What is the normal value of hemoglobin in elderly people

The normal value of hemoglobin in elderly people is generally 120-160g/L for males and 110-150g/L for females. The actual values may fluctuate due to factors such as age, chronic diseases, nutritional status, medication effects, and testing methods.

1. Age factor: As age increases, the hematopoietic function of the bone marrow gradually decreases, and the hemoglobin value of elderly people may be slightly lower than that of young people. The acceptable lower limit for males over 60 years old is adjusted to 110g/L, and the reference range for postmenopausal females is similar to that for males. This physiological decline usually does not require special intervention, but requires regular monitoring.

2. Chronic diseases:

Chronic kidney disease, heart failure, and other diseases may inhibit red blood cell production, leading to a decrease in hemoglobin. This type of situation is often accompanied by symptoms such as fatigue and shortness of breath, and requires targeted treatment for the underlying disease. For example, renal anemia requires the use of erythropoietin and monitoring of iron metabolism indicators.

3. Nutritional deficiency:

Insufficient intake of iron, folate, or vitamin B12 is a common cause of anemia in the elderly. Reduced gastric acid secretion affects iron absorption, and long-term vegetarianism may lack vitamin B12. It is recommended to confirm the type through blood routine and serum ferritin testing. Iron deficiency anemia can be supplemented with iron supplements such as ferrous succinate. 4. Drug effects: Anticoagulants such as aspirin may cause hidden gastrointestinal bleeding, while chemotherapy drugs can inhibit bone marrow hematopoiesis. During the use of these drugs, elderly people should have their blood routine checked every 3 months, and if necessary, adjust the medication plan or combine blood generating drugs for treatment.

5. Differences in detection:

Different detection equipment and blood collection sites may lead to numerical deviations between venous blood and peripheral blood. When fasting in the morning, hemoglobin levels are higher, and dehydration can cause a false increase in test results. It is recommended to have a follow-up examination at a designated hospital and maintain a normal amount of water intake before blood collection.

Elderly people need to pay attention to a balanced diet to maintain normal hemoglobin levels, and increase their intake of foods rich in hematopoietic materials such as lean meat, animal liver, and dark green vegetables in moderation. Aerobic exercise such as brisk walking for 30 minutes three times a week can improve bone marrow microcirculation. Patients with combined chronic diseases should follow medical advice for regular check ups and avoid taking blood supplements on their own. Pay attention to keeping warm in winter to prevent poor peripheral circulation from affecting the accuracy of detection. When detecting abnormalities, a comprehensive judgment should be made based on indicators such as hematocrit and reticulocyte count.
