Microcytosis is a condition in which the red blood cells (red blood cells) in the blood are smaller than normal. This condition is characterized by a decrease in the average red blood cell volume (mean corpuscular hemoglobin concentration, MCHC) and can be associated with a variety of medical causes.
The main cause of microcytosis is iron deficiency, as iron is necessary for normal hemoglobin formation in red blood cells. Other causes of microcytosis may include genetic disorders, anemia from chronic diseases, and other conditions that affect the formation and size of red blood cells.
Microcytosis can be one of the signs of various forms of anemia, such as microcytic hypochromic anemia. The diagnosis and treatment of microcytosis depends on the underlying cause, so if microcytosis is detected, it is important to have further testing and consultation with a physician to establish a diagnosis and determine appropriate treatment.
Causes of the microcytosis
Microcytosis (decreased red blood cell size) can be caused by a variety of medical reasons. The main and most common cause of microcytosis is iron deficiency, as iron is necessary for the normal formation of hemoglobin in red blood cells. The main causes of microcytosis include:
- Iron deficiency: Iron deficiency in the body can occur due to insufficient iron intake from food, poor iron absorption, or due to blood loss (e.g., from gastrointestinal bleeding or menstruation).
- Genetic disorders: Some genetic disorders, such as thalassemias and disorders of hemoglobin synthesis, can lead to microcytosis.
- Chronic diseases: Some chronic diseases, such as chronic inflammatory diseases or cancer, can affect red blood cell formation and lead to microcytosis.
- Persistent vitamin B6 deficiency: Vitamin B6 deficiency can also cause microcytosis.
- Iron deficiency anemia syndrome in children: This syndrome can occur in children with iron deficiency in early childhood.
- Severe infections and other conditions: Some severe infections, as well as some conditions such as thrombocytopenia, can also cause microcytosis.
To determine the exact cause of microcytosis and prescribe appropriate treatment, a physical examination and consultation with a physician is necessary.
Hypochromia and microcytosis are two related medical terms that describe changes in red blood cells (red blood cells). Hypochromia indicates a decrease in the hemoglobin content of red blood cells, making them paler. Microcytosis, on the other hand, indicates a reduced size of red blood cells.
Anisocytosis and microcytosis are also medical terms related to changes in red blood cells. Anisocytosis refers to the presence of different sized red blood cells in the blood. Microcytosis, as mentioned above, indicates a reduced size of red blood cells. Thus, anisocytosis and microcytosis can be combined when there are different sizes of red blood cells in the blood and most of them are reduced in size (microcytes).
Poikilocytosis and microcytosis are also related terms. Poikilocytes are red blood cells with an altered shape; they may be irregular or irregularly shaped. Microcytosis indicates a reduced size of red blood cells. Thus, poikilocytosis and microcytosis may be combined when small, irregularly shaped red blood cells are present in the blood.
These changes in red blood cells can be signs of various types of anemia and other medical conditions. For an accurate diagnosis and treatment, it is recommended to consult a doctor who will perform the appropriate tests and determine the cause of these changes in the blood.
Microcytosis in children
This is a condition in which the size of red blood cells (red blood cells) is reduced. It can result from a variety of medical conditions and diseases. It is important to note that microcytosis in children can be temporary or chronic and requires medical evaluation and treatment depending on its cause and severity.
Causes of microcytosis in children may include:
- Iron deficiency: A lack of iron in the body can lead to microcytosis, as iron plays an important role in the production of hemoglobin, which is found in red blood cells.
- Thalassemia: This is a group of genetic disorders that can lead to microcytosis. Thalassemia alters the structure and function of hemoglobin.
- Anemia of chronic diseases: Some chronic diseases, such as chronic inflammatory conditions or kidney disease, can cause microcytosis.
- Genetic disorders: Some genetic disorders may be associated with microcytosis.
- Syndromes: Some syndromes, such as diametric microcyte anemia syndrome and others, can lead to microcytosis.
Treatment of microcytosis in children depends on the cause. If the cause is iron deficiency, iron-containing medications and dietary adjustments may be necessary. If other medical conditions are present, treatment will focus on managing the underlying disease.
For an accurate diagnosis and treatment of microcytosis in children, it is necessary to consult a pediatrician or hematologist, who will conduct the necessary tests and determine the best treatment plan.

Treatment of the microcytosis
Treatment of microcytosis depends directly on its underlying cause. Here are some possible approaches to treating microcytosis:
- Treatment of iron deficiency: If the microcytosis is caused by iron deficiency, the main treatment is to take iron supplements under the supervision of a doctor. The doctor may recommend taking oral iron preparations such as ferrous sulfate. In some cases, when oral preparations are not effective or cannot be tolerated, intravenous iron may be required.
- Treatment of the underlying condition: If microcytosis is caused by chronic conditions such as chronic inflammatory conditions or cancer, treatment should be directed at the underlying condition. In such cases, it is important to follow the doctor's recommendations and treat the underlying condition.
- Vitamin therapy: If microcytosis is caused by vitamin B6 deficiency, treatment may include taking appropriate vitamin preparations.
- Dietary correction: Microcytosis can be caused by a dietary iron deficiency. In such cases, dietary adjustments should be made to increase the intake of iron-containing foods such as meat, fish, nuts and green vegetables.
- Health monitoring: It is important to keep in mind that the treatment of microcytosis should be carried out under the supervision of a doctor and depending on its underlying cause. Self-treatment can be insufficiently effective and even harmful. Therefore, if symptoms of microcytosis are present or suspected, a doctor should be consulted for diagnosis and treatment.
Forecast
The prognosis of microcytosis depends on its underlying cause and the effectiveness of treatment. In most cases, microcytosis can be successfully treated and improved with appropriate therapy. If microcytosis is caused by iron deficiency and is successfully treated with iron-containing drugs or dietary adjustments, the prognosis is usually favorable and the patient can expect normalization of the red blood cell count.
However, if microcytosis is associated with chronic diseases or conditions such as chronic anemia or chronic inflammation, the prognosis will depend on how well the underlying disease is managed. In some cases, microcytosis may be long-term or require ongoing medical monitoring and treatment.
It is important to see a doctor to diagnose and treat microcytosis, as it can be a sign of various medical conditions that require attention and care. The doctor will be able to perform the necessary examination, make the correct diagnosis and offer the best treatment, which will ultimately affect the prognosis of the disease.
