Glossary Protein Deficiency

insufficient dietary protein intake leading to health issues

Protein Deficiency, also known as Protein Malnutrition or Hypoproteinemia, occurs when the body does not get enough protein from the diet to meet its needs. This can lead to a range of health issues, including muscle wasting, weakened immune function, and in severe cases, conditions like kwashiorkor and marasmus. Protein is essential for the growth, repair, and maintenance of body tissues, and a deficiency can have significant impacts on overall health.
