What condition is low thyroid function likely to result in due to poor utilization of EFAs?

1. Eczema

2. High blood pressure

3. Insomnia

4. Weight gain

The correct answer is: Eczema

Low thyroid function, or hypothyroidism, can significantly affect the metabolism and utilization of essential fatty acids (EFAs) in the body. When the thyroid hormone levels are low, the body's overall metabolic processes slow down, which can impair the conversion and use of EFAs. This impairment can lead to various skin conditions, with eczema being a common outcome. Eczema often manifests as dry, inflamed skin, which can be exacerbated by the inadequate incorporation of essential fatty acids that are crucial for maintaining skin barrier function and hydration. The presence of essential fatty acids is vital for skin health, as they play a role in creating the lipid barrier that protects the skin. When thyroid function is compromised, the skin may not receive adequate support in terms of EFAs, leading to dry, itchy, and inflamed skin, characteristic of eczema. While the other conditions listed—high blood pressure, insomnia, and weight gain—can be associated with thyroid dysfunction, the direct link between low thyroid function and poor utilization of essential fatty acids primarily leads to skin issues like eczema. Therefore, eczema is the most fitting answer in this context.
