Given below are symptoms of malnutrition in children, adults and elderly people.

Symptoms of Malnutrition in ChildrenMalnutrition mostly affects infants and growing children. A malnourished child may exhibit symptoms such as loss of appetite, weight loss, fatigue, low energy, decreased immune response, dizziness and slow reflexes. Malnutrition in children also causes swelling and pain in joints, osteoporosis, growth retardation, tooth decay and bleeding gums, swollen abdomen, dry and flaky skin, muscle weakness and trembling. Low organ functioning, poor memory, night blindness due to vitamin A deficiency and diarrhea are present too. Lack of dietary energy and protein lead to kwashiorkor and marasmus, two conditions which typically represent malnutrition and its negative effects.Symptoms of Malnutrition in Adults
