Malnutrition is a condition that results from the lack of food or lack of food that contains the proper nutrients the human body requires in order to keep functioning properly. In some cases, a person may continue to consume what they consider food, but it may not contain sufficient amounts of vitamins, minerals, and other nutrients to fulfill all of their needs. Medically speaking, someone who loses between 5 and 10 percent (or more) of their body weight in the course of three to six months and is not dieting is likely to be suffering from malnutrition. Here are other signs and symptoms to watch for.
General weakness and increased feelings of fatigue are often signs of malnutrition. Finding that daily activities are too tiring or simply too hard to complete are telltale signs, as are muscles that have visibly decreased in size, and an appearance of overall weakness, similar to when a person is suffering from an illness such as the flu.
