Hypovitaminosis A: symptoms, causes, and treatment

Definition and symptoms of Vitamin A deficiency

Hypovitaminosis A is a condition of vitamin A deficiency in the body, which can lead to various pathological processes. Symptoms of hypovitaminosis A include visual disturbances, dryness of the skin and mucous membranes, night blindness, growth of teeth and bones, decreased immunity, and possible disruption of reproductive function.

Factors contributing to the development of Vitamin A deficiency

Hypovitaminosis A can develop due to insufficient consumption of foods containing vitamin A or due to impaired absorption in the intestines. One of the common factors contributing to the development of hypovitaminosis A is an irrational diet that is poor in vitamin A in the form of fat-soluble compounds. Other factors may include diseases of the gastrointestinal tract, abnormalities of the gallbladder or liver, which can reduce the absorption of vitamin A and contribute to its deficiency.

  • Insufficient intake of foods high in vitamin A: Insufficient consumption of animal products, such as milk, egg yolks, and liver, can lead to a deficiency of vitamin A in the body.
  • Gastrointestinal diseases: Some gastrointestinal diseases, such as chronic gastritis, celiac disease, or cholecystitis, can reduce the absorption of vitamin A and contribute to hypovitaminosis.
  • Food allergies or intolerances: People with food allergies, especially to animal products, may restrict their diet and therefore not obtain enough vitamin A.
  • Alcohol or drug intoxication: Excessive consumption of alcohol or drugs can disrupt the absorption and metabolism of vitamin A in the body.
  • Surgical interventions: Performing surgical procedures on the digestive system, especially the stomach or intestines, can reduce the body’s ability to absorb vitamin A from food, leading to a deficiency.

Symptoms of vitamin A deficiency

Symptoms of vitamin A hypovitaminosis can manifest a wide range of clinical signs, including night blindness, dryness and irritation of the cornea, as well as increased vulnerability to infections due to impaired immune function. Skin manifestations, particularly dryness and flaking, can also be the first signs of vitamin A deficiency. Additionally, individuals with vitamin A hypovitaminosis may experience growth problems in children, reproductive system disorders, as well as other symptoms related to the functioning of various body systems.

  • Night blindness: one of the characteristic symptoms of vitamin A deficiency is the deterioration or loss of vision due to lack of the vitamin.
  • Dryness and irritation of the eyes: a deficiency of vitamin A can cause dryness and discomfort in the eyes, as well as impairment of visual function.
  • Increased vulnerability to infections: vitamin A deficiency can lead to impaired immune function, making the body more susceptible to infections.
  • Dryness and flaking of the skin: one of the visual manifestations of vitamin A deficiency is dryness and flaking of the skin, especially on the face.
  • Growth and development problems in children: children with vitamin A deficiency may face delays in growth and development, including issues with bones and teeth.

Expert opinions on the treatment of vitamin A hypovitaminosis

Experts’ opinions on the treatment of vitamin A hypovitaminosis are based on the use of vitamin preparations containing vitamin A in appropriate doses. Experts recommend monitoring the vitamin level in the patient’s blood and adjusting the dosage accordingly to avoid both deficiency and excess of this vitamin.

Moreover, specialists emphasize the importance of rational nutrition considering the content of vitamin A in foods. Dietary consultations and recommendations from specialists help supplement treatment with vitamins and minerals through a varied and nutritious diet, which contributes to restoring normal vitamin A levels in the body.

Diagnosis of vitamin A deficiency

The diagnosis of vitamin A deficiency includes a comprehensive medical analysis of symptoms, investigation of the patient’s history and diet, as well as laboratory tests to determine the level of vitamin A in the blood. Clinical signs such as changes in vision, condition of the skin and mucous membranes, as well as symptoms indicating possible growth disorders in children and functioning of the reproductive system, are considered in the diagnosis of vitamin A deficiency.

Additional diagnostic methods may include measuring the level of vitamin A in serum, radiological studies to assess the condition of the patient’s skeleton and joints, as well as other laboratory tests necessary for a complete evaluation of the degree of vitamin A deficiency in the body. Early and accurate diagnosis of vitamin A deficiency allows for timely implementation of appropriate treatment and prevention of potential complications from the lack of this important vitamin.

  • Analysis of clinical signs: the doctor examines the patient and assesses the symptoms of vitamin A deficiency, such as changes in vision, skin condition, and mucous membranes.
  • Investigation of medical history and nutrition: it is important to inquire about previous illnesses, nutrition, and risk factors that may have contributed to the development of vitamin A deficiency.
  • Laboratory tests for vitamin A levels: testing vitamin levels in the blood will help determine the degree of deficiency and develop a treatment plan.
  • Radiological studies: if necessary, X-rays are performed to assess the condition of the skeleton and joints.
  • Additional laboratory tests: depending on the clinical picture, additional tests may be ordered for a more complete diagnosis of vitamin A deficiency.

Treatment of vitamin A deficiency

Treatment of vitamin A hypovitaminosis usually involves the prescription of vitamin preparations containing vitamin A, under the supervision of a doctor. The individual dosage and duration of use depend on the degree of vitamin deficiency in the patient’s body. Proper nutrition, rich in sources of vitamin A, such as egg yolks, dairy products, liver, and vegetables high in carotenoids, is also important in treatment recommendations.

In addition, treatment of vitamin A hypovitaminosis may include symptomatic therapy to improve the condition of the skin, vision, and other organs and systems affected by the lack of vitamin A. It is important to emphasize that self-treatment with vitamin A can lead to overdose, which is dangerous for health, so it is necessary to follow the recommendations of a specialist and undergo treatment under their supervision.

  • Purpose of vitamin preparations: Treatment of vitamin A deficiency begins with the prescription of specialized preparations containing vitamin A, under strict medical supervision, taking into account the individual needs of the patient.
  • Proper nutrition: It is recommended to include sources of vitamin A in the diet, such as egg yolks, dairy products, liver, and vegetables high in carotenoids, to maintain normal vitamin levels in the body.
  • Symptomatic therapy: To improve the condition of the skin, vision, and other organs and systems affected by vitamin A deficiency, symptomatic therapy may be employed, specifically tailored for each patient.
  • Specialist control: To avoid possible overdose and complications from vitamin A deficiency or excess, it is important to conduct treatment under strict medical supervision and to follow the doctor’s recommendations.
  • Avoiding self-medication: Self-prescribing and increasing the dosage of vitamin A preparations can be dangerous and lead to undesirable consequences, so it is necessary to avoid self-medication and follow the instructions of a specialist.

Prevention of hypovitaminosis A

The prevention of vitamin A hypovitaminosis includes a balanced diet rich in sources of vitamin A, such as eggs, dairy products, liver, vegetables, and fruits high in carotenoids. Moderate consumption of these foods according to recommended doses helps maintain normal levels of vitamin A in the body.
