Nutrients are the structural components of food that the body needs to function properly. They are divided into macronutrients (proteins, fats, carbohydrates) and micronutrients (vitamins, provitamins, various minerals, and so on). Their shortage is called nutritional deficiency.
In medicine, there is a special term – cardiac cachexia. It is the extreme emaciation of the body in patients with severe cardiac failure. The reasons can be many: from low cardiac output to drugs that suppress appetite. Symptoms of cardiac cachexia include weakness and rapid weight loss. As a result, nutrients are not supplied to the body in the right quantities.
