Final answer:
Vitamin E deficiency in adults can lead to dry and scaly skin, poor wound healing, increased susceptibility to infections, and other issues such as impaired growth and reproduction, hair loss, and sensitivity to insulin.
Step-by-step explanation:
In the rare case that an adult has vitamin E deficiency, the signs and symptoms may vary. Some common manifestations include dry and scaly skin, poor wound healing, and increased susceptibility to infections. Vitamin E plays vital roles in protecting cell membranes from oxidative damage and is also essential for the immune system and other metabolic processes. Impaired growth and reproduction, loss of hair, sensitivity to insulin, and the burning feet syndrome may also occur as a result of vitamin E deficiency. It is important to ensure adequate intake of this vitamin to prevent these health issues.
