Hypoproteinemia is a pathological condition that is characterized by a decrease in the plasma concentration of total protein less than 64 g / l. The causes are starvation, kidney and liver diseases. The clinical picture can be varied - from an asymptomatic course to the appearance of peripheral edema, effusion in the abdominal, thoracic, pericardial cavities, and increased susceptibility to infections. The protein level is examined in plasma on an empty stomach. To eliminate hypoproteinemia, protein deficiency is compensated and the underlying disease is treated.
