Nutritional Deficiencies
Nutritional deficiencies (pronunciation: /nuːˌtrɪʃənəl dɪˌfiːʃənˈsiːz/) refer to the state of lacking essential nutrients in the diet, which can lead to various health problems.
Etymology
The term "nutritional deficiencies" is derived from the words "nutrition" and "deficiency". "Nutrition" comes from the Latin word nutritio, meaning "nourishment", while "deficiency" comes from the Latin word deficientia, meaning "lack".
Types of Nutritional Deficiencies
There are several types of nutritional deficiencies, including:
- Vitamin Deficiency: This occurs when the body does not get or cannot absorb the necessary amount of a vitamin. Examples include Vitamin A Deficiency, Vitamin B12 Deficiency, and Vitamin D Deficiency.
- Mineral Deficiency: This happens when the body lacks essential minerals. Examples include Iron Deficiency, Calcium Deficiency, and Zinc Deficiency.
- Protein-Energy Malnutrition: This is a type of malnutrition that results from a lack of protein and energy in the diet. Examples include Kwashiorkor and Marasmus.
Symptoms
Symptoms of nutritional deficiencies vary depending on the specific nutrient that is lacking. However, common symptoms include fatigue, dizziness, and weight loss. More severe deficiencies can lead to diseases such as Scurvy (due to Vitamin C deficiency), Rickets (due to Vitamin D deficiency), and Pellagra (due to Niacin deficiency).
Prevention and Treatment
Prevention and treatment of nutritional deficiencies typically involve dietary changes to ensure a balanced intake of essential nutrients. This may include eating a variety of foods, taking dietary supplements, and in severe cases, receiving medical treatment such as Intravenous Therapy.
