Poor body absorption can be injected with albumin, but generally if there is no hypoproteinemia or malnutrition is not the need to inject albumin, normal people every day the body synthesized albumin is enough to use. Albumin is an important nutrient in the composition of the human body, mainly synthesized by the liver, mainly plays an important function in maintaining the balance of fluid inside and outside the blood vessels and transporting nutrients. In the case of kidney disease, albumin may be lost in the urine. In the case of liver disease, the synthesis of albumin will be reduced, and a severe albumin deficiency will cause hypoproteinemia. Albumin injections are usually needed when hypoproteinemia or significant malnutrition is present. In most cases, albumin injections are not necessary, and the body can synthesize enough albumin each day for a normal person. Protein helps synthesize albumin. Protein-rich foods such as milk, eggs and meat can be consumed. Poor body absorption suggests that patients go to the hospital for examination to see if there is a digestive system disease, whether the need to inject albumin, it is recommended that patients check and listen to the doctor’s advice.
