Low Protein in Blood
Blood protein is used to evaluate as a routine blood work for patients with malnutrition, immune disorders, cancer, diseases of kidney, liver and intestines and digestive disorders. The normal protein levels are between 6.4 and 8.3 grams/dl (decilieter). The Low protein in blood is caused due to overhydration, malabsorption, malnutrition, immune deficiency, liver disease and some drugs. A blood test that reveals low protein and albumin levels is a sign of underlying health conditions. Albumin and globulin are major proteins, but albumin has a vital role in your body functions.
Causes for Low Protein in Blood
- Liver Diseases: Protein tests reveal the ratio of albumin to globulin. The protein normal level is between 6.0 and 8.3 g/dL, while the albumin normal ranges between 3.4 and 5.4g/dL. A blood test showing albumin in low levels may show liver damage or dysfunction. Decreased levels of albumin relate to diseases such as hepatitis. Low albumin may cause abdomen swelling.
- Malabsorption Syndrome: Low levels of albumin develop in case there is malabsorption resulting in the inability to break certain food nutrients in your digestive system. Malabsorption is indicated when sugars, fats and other nutrients do not digest properly. This condition also includes milk intolerances, etc.
- Renal Problem: Albumin levels indicate disorders or diseases of kidney. As albumin is lost through urine, the protein levels decrease. This is apparent in glomerulonephritis, a symptom of Nephrotic syndrome and is associated with kidney disorders.
- Overhydration: The levels of blood protein reveal proteins concentration. The blood volume increases with overhydration causing the protein levels to decrease in proportion. The albumin and globulin levels are normal, but the protein to fluid ratio has decreased.
- Immune Deficiency: The immunoglobulins building block is the globulin, the main protein. The immunoglobulins number gets reduced with immune deficiency and this reduces the protein levels in the blood. Nutritional deficiencies happen due to not getting enough protein through diet and may cause low protein in blood.
