nutritional deficiency
Missing essential nutrients
A nutritional deficiency is a lack of essential nutrients—vitamins, minerals, proteins, or other substances the body needs to function properly.
Deficiencies result from inadequate diet, poor absorption, or increased bodily demands.
Iron deficiency causes anemia.
Vitamin D deficiency weakens bones.
Severe deficiencies can cause disease: scurvy from lack of vitamin C, rickets from lack of vitamin D.
