Effects of Vitamin A Deficiency
A deficiency in vitamin A can have several negative effects on the body, including:
- Impaired vision, including night blindness and eventually blindness

Preventing and Treating Vitamin A Deficiency
Preventing vitamin A deficiency involves consuming a diet rich in vitamin A-containing foods. For those at risk of deficiency, vitamin A supplements may be recommended. In cases of severe deficiency, medical intervention may be necessary to prevent long-term health complications.
Case Study: Impact of Vitamin A Supplementation
A study conducted in a rural community in Africa found that providing vitamin A supplements to children reduced the incidence of childhood blindness and improved overall health outcomes. This highlights the importance of addressing vitamin A deficiency in at-risk populations.
