What happens if you eat too much rock sugar orange?

Eating too many oranges can cause poisoning, resulting in yellowing of the skin of the hands and feet. In severe cases, symptoms such as nausea, vomiting, irritability and lack of energy may also occur. This is because a large amount of carotenoids are absorbed into the blood and deposited in the superficial skin tissue, causing the skin to turn yellow. This phenomenon is commonly known as citrus disease. However, this symptom does not require treatment and will gradually improve as long as you stop eating sugar oranges.
