Taking gastric drugs generally does not affect total protein. Total serum protein is an indicator of liver function, which can reflect the function of the liver; elevated total serum protein can be seen in normal people, but also in patients with dehydration, cirrhosis, autoimmune hepatitis and other diseases; low total serum protein can be seen in newborns, infants and young children, pregnant women and other groups of people, as well as nephrotic syndrome, terminal cirrhosis, advanced malignant tumors and other diseases. Gastric drugs are generally used for the treatment of gastrointestinal diseases, such as omeprazole, lansoprazole, aluminum thioglycollate, domperidone, mosapride, bismuth potassium citrate, etc. Taking the above drugs generally does not cause abnormal total protein values. If abnormal total protein values occur, it is recommended to go to the hospital and ask the doctor to make a judgment and clarify the cause of the disease.
