Low protein levels, also known as hypoproteinemia, can manifest in various ways. Symptoms aren't always obvious and can vary in severity depending on the extent of the deficiency.
Common Symptoms of Low Protein
- Weakness and Fatigue: This is a very common symptom, as protein is essential for energy production and muscle function. (WebMD, UCLA Health, Healthline, Medical News Today, SELF)
- Swelling (Edema): Fluid can build up in the body, causing swelling in the extremities, abdomen, or other areas. (WebMD, Health.com)
- Hair, Nail, and Skin Problems: Brittle nails, hair loss, and dry, flaky skin can all be signs of protein deficiency. These are often early indicators. (WebMD, UCLA Health, Health.com, SELF)
- Mood Changes: Protein plays a crucial role in brain function and neurotransmitter production; therefore, deficiency can lead to irritability, depression, or anxiety. (WebMD)
- Increased Hunger: Despite consuming sufficient calories, a persistent feeling of hunger can be a symptom, as protein promotes satiety. (WebMD, Healthline)
- Slow-Healing Injuries: Protein is essential for tissue repair. With insufficient protein, wounds may take longer to heal. (WebMD)
- Increased Susceptibility to Illness: A weakened immune system, due to low protein, results in more frequent or longer-lasting infections. (Health.com, SELF)
- Stunted Growth (in children): Protein is vital for growth and development in children; deficiency can lead to stunted growth. (Health.com)
Note: The severity and presence of these symptoms vary greatly. A blood test measuring total protein and albumin levels is necessary for a proper diagnosis. Many underlying conditions can contribute to low protein levels, including malnutrition, liver or kidney disease, and certain autoimmune disorders.
