Vitamin A deficiency, unspecified
Clinical Classification Guidelines
Inclusion Terms
- Hypovitaminosis A NOS
Medical Intelligence & Overview
Vitamin A deficiency, classified under ICD-10 code E50.9, occurs when the body does not have enough vitamin A to perform vital functions. This essential nutrient is crucial for maintaining healthy vision, skin, immune system, and cellular growth. While vitamin A deficiency is more common in developing countries, it can affect individuals worldwide, especially those with poor nutrition or certain health conditions. Recognizing the signs and understanding the causes can help in managing or preventing this deficiency.
Causes & Symptoms
Clinical Causes: Inadequate dietary intake of vitamin A-rich foods such as liver, fish, dairy products, and colorful fruits and vegetables. Malabsorption syndromes like celiac disease, Crohn's disease, or pancreatic insufficiency that impair nutrient absorption. Liver disorders that hinder vitamin A storage and release. Increased physiologic needs during pregnancy, breastfeeding, or rapid growth phases. Certain medical conditions and medications that interfere with vitamin A metabolism. Infections that increase nutritional demands or cause malnutrition.
Key Symptoms: Night blindness, difficulty seeing in low light or darkness. Dryness of the eyes, leading to conjunctival and corneal dryness (xerophthalmia). Bitot spots—foamy, grayish patches on the conjunctiva. Dry, rough, or hardened skin. Frequent infections due to compromised immune function. Delayed growth and development in children. Corneal ulcers and, if severe, complete blindness. Bleeding tendencies and delayed wound healing in severe cases.
Diagnostic & Treatment
Diagnosis Path: Diagnosis of vitamin A deficiency primarily involves clinical assessment of symptoms and dietary history. Laboratory tests can measure serum retinol levels to confirm deficiency. Additional tests may include eye examinations for signs like Bitot spots and keratomalacia. Healthcare providers may also evaluate related nutritional deficiencies and overall health status to determine underlying causes.
Treatment Protocols: Management typically involves improving dietary intake of vitamin A through foods rich in this nutrient. In specific cases, healthcare providers may recommend vitamin A supplements, especially in populations at risk for deficiency. Treatment strategies aim to restore adequate levels safely to avoid toxicity. Addressing any underlying conditions such as malabsorption or liver diseases is also essential for effective management. Regular monitoring of vitamin A levels and symptoms forms part of ongoing care.
