Proteins, also known by their Latin name Proteins, are one of the three macronutrients our body needs. Proteins are particularly important for building and maintaining muscles, tissues, enzymes, and hormones. Consequently, a deficiency in proteins can cause numerous symptoms and significantly impact health. We aim to clarify the causes, symptoms, and treatment options of protein deficiency.

The Importance of Protein for the Body

Proteins play numerous roles in the human body, so we can only provide an overview of the most important functions. Protein is essential for building and maintaining muscle tissue. Particularly active individuals and athletes have an increased protein requirement.

Additionally, protein is of great significance for numerous cell structures and components of tissues. Skin, hair, nails, bones, tendons, and organs can function properly only with an adequate intake of proteins.

Enzymes facilitate biochemical reactions in the body, enabling metabolism. Enzymes are, in fact, very specialized proteins, emphasizing their significance once again.

Hormones are also proteins. For example, insulin is a hormone that enables energy production by allowing sugar to enter cells from the blood.

Our immune system wouldn't function without proteins, as antibodies are also proteins. They function by destroying viruses and bacteria, which are also composed of proteins.

Lastly, proteins also play crucial transport and buffering roles throughout the organism, allowing us to function and survive as complex beings.

Common Causes of Protein Deficiency

A protein deficiency usually arises due to malnutrition, which lacks sufficient healthy proteins. Therefore, pay attention to diverse and varied sources of protein in your diet. Proteins consist of amino acids as components. Therefore, it's essential not only to have an adequate protein intake but also to ensure sufficient intake of essential amino acids, which are amino acids that the human body cannot synthesize on its own.

In addition to malnutrition, specific circumstances can lead to an increased protein requirement or inadequate protein intake. During pregnancy, for example, an increased need for protein arises, as does in sports. Illnesses can sometimes trigger an increased protein requirement or hinder the absorption of proteins from the diet. It is important to consult a doctor and determine the cause if there is suspicion of protein deficiency.

Common Symptoms of Protein Deficiency

We have seen above the range of bodily functions proteins are involved in. Consequently, the consequences of protein deficiency can be extensive. To diagnose a deficiency accurately, a doctor's visit is necessary. The following symptoms may indicate a protein deficiency. Additionally, a deficiency in amino acids can lead to similar symptoms:

  • Muscle Weakness and Atrophy: In the absence of protein for muscles, they may undergo atrophy.
  • Reduced Immune Function and Susceptibility to Infections: Proteins play a critical role in the immune system, so a protein deficiency can lead to corresponding symptoms.
  • Structural Changes in Skin, Hair, and Nails: Proteins are necessary for collagen and keratin, so related structures may change. Brittle hair, fragile nails, and dry skin are typical.
  • Edema: A deficiency in proteins could disrupt osmosis. Consequently, water retention in the legs, for example, might occur.
  • Fatigue and Fatigue: The energy metabolism can be impaired.
  • Slowed Wound Healing: Proteins play a significant role in wound healing.
  • Weight Loss: Various body structures can be broken down in the presence of deficiency.
  • Psychological Symptoms of Protein Deficiency: Since proteins are also necessary for neurotransmitters, mood swings may occur.

By the way: Too much protein can cause kidney strain, digestive problems, dehydration, and calcium loss. Therefore, prevention of deficiency is important, and excessive protein intake should also be avoided. Keep an eye out for symptoms of excessive protein intake as well.

Proteinmangel: Diagnosis and treatment

If there is a suspicion of protein deficiency due to protein deficiency symptoms, a visit to the doctor is advised. The diagnosis is usually done following this scheme:

  1. Medical History and Physical Examination: These preliminary tests are needed for your doctor to assess suitable diagnostic methods.
  2. Blood Test: A blood test provides information about the total protein content in the blood. Your doctor can determine if there is too little protein in the blood. Specific proteins can also be measured to enable more accurate assessments.
  3. Urine and Stool Analysis: These can provide further insight into the causes and severity of protein deficiency. Additional tests may be necessary to rule out other causes of the symptoms.

Treatment typically involves dietary changes. Your doctor will recommend increased intake of protein-rich foods, including more meat, fish, eggs, dairy products, legumes, nuts, and seeds. Temporary supplementation with protein powders can help address acute protein deficiency. However, such powders are not a long-term solution.

Additionally, if present, the underlying cause will be treated. Conditions like kidney issues or gastrointestinal diseases can lead to or exacerbate protein deficiency.

For severe protein deficiency, medical monitoring may be necessary. In such cases, you will be regularly examined and supervised to prevent significant health damage.

Protein Deficiency: Frequently Asked Questions

What Does Protein Do in the Body?

Protein is involved in numerous bodily functions. Muscle mass, hormones, enzymes, and much of the tissue such as skin and hair rely on proteins. A protein deficiency thus affects numerous bodily functions.

How Do I Recognize Protein Deficiency?

You can recognize this by the symptoms mentioned above. It is particularly important that if you suspect it, you seek a doctor's advice without delay. Only a doctor has the necessary diagnostic methods to properly diagnose protein deficiency. Your doctor will also explain the appropriate treatment.
