Hypervitaminosis A
Hypervitaminosis A[edit | edit source]
Hypervitaminosis A refers to abnormally high storage levels of vitamin A in the body, leading to toxicity. This condition can cause a range of symptoms including headache, blurred vision, nausea, vomiting, and dizziness. In severe cases, it can also lead to birth defects.
Causes[edit | edit source]
The primary cause of Hypervitaminosis A is the excessive intake of vitamin A, either through diet or more commonly through overuse of supplements.
Dietary Sources[edit | edit source]
High intake of foods rich in vitamin A, such as liver, can contribute to elevated levels, though this is less common than supplement-induced toxicity.
Supplements[edit | edit source]
Overuse of vitamin A supplements is the most common cause of Hypervitaminosis A.
Symptoms[edit | edit source]
Symptoms of vitamin A toxicity include:
- Chronic symptoms: Liver damage, vision changes, osteoporosis, and skin changes
- Acute symptoms: Headache, blurred vision, nausea, vomiting, dizziness
Diagnosis[edit | edit source]
Diagnosis involves a review of dietary and supplement intake, blood tests to measure vitamin A levels, and assessment of symptoms.
Treatment[edit | edit source]
Treatment focuses on discontinuing excess vitamin A intake. In severe cases, medical intervention may be necessary.
Prevention[edit | edit source]
Prevention involves:
- Adhering to recommended dietary allowances for vitamin A
- Avoiding large doses of vitamin A supplements
- Being aware of vitamin A content in prescribed medications
