What causes low hemoglobin

Low hemoglobin often makes people feel exhausted and even affects their daily life. Hemoglobin, also known as hemoglobin, is a protein in red blood cells that is responsible for transporting oxygen from the lungs to various parts of the body. When hemoglobin levels are low, the body's oxygen supply will be affected, leading to a series of uncomfortable symptoms. So, what exactly causes low hemoglobin?

Malnutrition is one of the common causes of low hemoglobin. Our bodies need nutrients such as iron, vitamin B12 and folic acid to produce hemoglobin. If these nutrients are lacking in the diet, it may cause anemia, which in turn leads to low hemoglobin. For example, if vegetarians do not pay attention to iron supplementation, they may suffer from low hemoglobin levels due to iron deficiency.

In addition to malnutrition, chronic diseases are also important factors leading to low hemoglobin. Chronic kidney disease, chronic inflammatory diseases, cancer, etc. may affect the production and lifespan of red blood cells, leading to a decrease in hemoglobin levels. The kidneys play an important role in the production of red blood cells, and chronic kidney disease may affect this process, leading to anemia.

Blood loss is also a common cause of low hemoglobin. Acute blood loss such as trauma, surgical bleeding, or chronic blood loss such as gastrointestinal ulcers and excessive menstruation will lead to a decrease in the number of red blood cells in the blood, which in turn causes low hemoglobin. Women are especially prone to anemia due to blood loss due to their menstrual period.

Of course, blood diseases are also one of the reasons that cannot be ignored. Hereditary blood diseases such as thalassemia and sickle cell anemia will directly affect the production and function of hemoglobin. Some autoimmune diseases may also cause premature destruction of red blood cells and affect hemoglobin levels.

If you find yourself with symptoms of low hemoglobin, such as fatigue, dizziness, palpitations, etc., it is recommended to see a doctor as soon as possible. Through blood routine tests, you can preliminarily determine the hemoglobin level and further find out the cause. Depending on the cause, the doctor will give corresponding treatment suggestions, such as adjusting the diet, supplementing nutrients, or treating underlying chronic diseases. Maintaining good living habits and paying attention to a balanced diet are also important measures to prevent low hemoglobin. I hope this information can provide you with some help and let us walk more steadily on the road to health.
