Symptoms of low protein

Low protein levels are clinically referred to as hypoalbuminemia. Common symptoms include malnutrition, fatigue, edema, and skin changes. The specific manifestations may vary among different patients.

1. Malnutrition: Hypoalbuminemia can lead to significant loss of subcutaneous fat and skeletal muscle, causing patients to become progressively thinner. Additionally, atrophy of the gastrointestinal mucosa, reduced gastric acid secretion, and decreased digestive enzymes can result in poor appetite, insufficient nutrient intake, and ultimately malnutrition and delayed growth and development.

2. Fatigue: Due to insufficient protein levels in the body, the energy required for physical activities cannot be adequately supported. As a result, patients tend to avoid exercise and experience declining physical strength. Over time, this may lead to slowed reactions and impaired memory. Most patients also have anemia, which can cause symptoms such as fatigue, weakness, and dizziness.

3. Edema: Hypoalbuminemia leads to low plasma albumin levels and reduced effective plasma osmotic pressure, promoting excessive fluid retention in tissue spaces and resulting in edema. Mild edema typically appears in the lower limbs and ankles; moderate edema involves swelling of the trunk, abdominal wall, face, and eyelids; severe edema may manifest as pleural effusion or ascites.

4. Skin changes: Insufficient protein intake deprives the body of essential nutrients, affecting the growth of skin, hair, and other skin appendages. This may lead to dry, dull, inelastic skin with pigmentation. Hair may become dry, brittle, thin, lackluster, and prone to breakage or shedding.

Furthermore, if the condition continues to progress, complications such as electrolyte imbalances, increased susceptibility to infections, and pressure ulcers may develop. It is important to seek timely medical evaluation and receive appropriate treatment under a physician's guidance.
