Which term refers to a condition that results from a deficiency in nutrients?

The term that refers to a condition resulting from a deficiency in nutrients is malnutrition. Malnutrition encompasses both undernutrition, where there is an inadequate intake of essential nutrients, and imbalances, where the body doesn't receive the right proportions of different nutrients. It indicates that an individual is not getting enough vitamins, minerals, proteins, carbohydrates, or fats necessary for good health, leading to various health issues.

In contrast, hypernutrition and overnutrition refer to an excess of nutrient intake, which can lead to obesity and related health problems. Co-morbidity describes the presence of one or more additional conditions co-occurring with a primary condition but does not specifically relate to nutrient deficiencies. Therefore, malnutrition is the most accurate term to describe health conditions arising from a lack of essential nutrients in the diet.
