World Protein Day 2026: Hidden Signs You May Be Protein Deficient

Protein plays significant role in the structure and function of our muscles, skin, hormones, and enzymes as it is one of body’s major building blocks. Its deficiency will cause hair loss, rising hunger, edema, and infections. The situation of protein deficiency occurs when our intake fails to fulfill body’s needs. When the body does not get adequate proteins or amino acids, it cannot perform regular functions.

One of the most severe types of deficiency of protein is called kwashiorkor that generally takes place in children in developing nations due to malnutrition and imbalanced diet. Below are some of the symptoms of protein deficiency:

Hidden Signs of Protein Deficiency

Edema: The condition leads to swollen and puffy skin. It occurs due to inadequate amounts human serum albumin, one of the most abundant forms of proteins in the liquid part of blood or blood plasma, according to healthline.  The major function of albumin is to maintain oncotic pressure, a force that draws fluid into blood circulation. Albumin helps in preventing excessive amounts of fluid from accumulating in tissue or other body compartment. When there is a decreased human serum albumin levels, it can cause lower oncotic pressure. Consequently, fluid starts to accumulate in tissue and it leads to swelling. Edema occurs when there is a major deficiency of protein.  

Fatty Liver: Deficiency of protein can cause fatty live or fat begins to accumulate in the liver cells. In developing country, inadequate intake of protein can cause fatty live. It can further lead to inflammation, liver scarring, and liver failure in extreme conditions. According to a research conducted by National Library of Medicine, protein deficiency causes fatty liver as a result of change in the gut microbiome, mitochondria, and peroxisomal cells. It can cause weakened synthesis of fat-transporting proteins namely lipoproteins.

Hair Fall: Deficiency of protein can impact skin, hair, and nails as they are largely made of protein. Inadequate intake of protein can affect hair growth and structure that could further cause severe hair loss also known as telogen effluvium. When children suffer from Kwashiorkor, it causes flaky skin, redness, or patches of depigmented skin. However, such symptoms will appear when there is severe deficiency of protein.  

Loss of Muscle Mass: One of the major signs of protein deficiency is muscle loss. Muscles may break down faster than they could rebuild thus leaving you weaker over time. When the body does not receive adequate dietary protein, it starts taking protein from skeletal muscles in order to save more vital tissues and body functions. Consequently, inadequate protein can cause muscle wasting over a period of time. It is worth noting that even moderate deficiency of protein can cause muscle wasting in older adults. Sufficient protein intake will prevent sarcopenia, muscle loss linked with aging, added healtline report.  

Increased Risk of Fractures: Insufficient intake of protein can lead to weaken bones and rising risk of fractures especially in older adults by accelerating bone mineral density or BMD loss. Low protein intake can cause decreased IGF-1 levels, crucial for bone formation and calcium absorption. Adequate intake of protein is necessary for improved bone and health and reduced risks of hip fractures.  

Rise In Infections: Protein deficiency can impact immunity in longer run. Sufficient intake of protein-rich diet can help in building antibodies that are produced by white blood cells to ward off infections.
