Malnutrition may manifest in different ways. Those who are suffering from it may not have the appetite in order to eat food that they are required to consume. They may also feel that they are tired all the time as the body is unable to get the nutrients in minerals that it needs to survive.
Some may feel that they are irritable for no reason. Those who have this condition may also notice that there are times when they get sick more often. If they would get wounds, their wounds do not heal immediately. When a person who regularly eats food start experiencing these symptoms, going to the doctor is the most obvious solution.
