What are the potential health consequences of excessive vitamin A intake?

Excessive vitamin A intake can lead to toxicity, which is a serious condition that manifests through various symptoms. One of the most notable aspects of vitamin A toxicity is the onset of symptoms such as headaches, nausea, and liver damage. The liver plays a crucial role in storing vitamin A, and when levels exceed the body's needs, it can result in hepatic dysfunction. Additionally, symptoms can also include dizziness, blurred vision, and in severe cases, elevated intracranial pressure, which may lead to headaches.

Understanding the critical nature of vitamin A is essential, as it is a fat-soluble vitamin, meaning that it can accumulate in the body's tissues if consumed in excess. This accumulation can disrupt normal physiological functions, leading to more severe health consequences if not addressed.

While skin irritation, hair loss, vision problems, fatigue, heart disease, and kidney failure can be associated with various health conditions, they are not the primary consequences directly linked to high vitamin A intake. Therefore, option B accurately captures the key symptoms related to vitamin A toxicity, emphasizing the need for balanced intake to avoid these potential health risks.
