Hypervitaminosis A

Hypervitaminosis A is the excessive accumulation of vitamin A in the body, generally from prolonged use of supplements or from very high doses over a long period. Although this vitamin is necessary for vision, the skin, and the immune defenses, in excess it can become toxic and affect various organs.

Frequent symptoms: headache, nausea, dryness and peeling of the skin, hair loss, pain in bones and joints, and sometimes blurred vision or irritability.

Common causes: excessive use of vitamin supplements without supervision or a very high intake through certain foods of animal origin.

Which specialist treats it? The internist and the nutritionist are the ones who can evaluate vitamin intake and provide guidance on safe consumption. If supplements are being taken and persistent symptoms appear, the recommended course is to discuss it with a professional before continuing.
