If a pregnant woman has edema in the sixth month, how to treat it needs to distinguish between different situations. If the edema is limited edema, it may be caused by inflammation, trauma, mosquito bites, applying drugs for different situations, it is best to focus on topical medications, because any drugs taken orally may adversely affect the fetus, so as to make the local edema disappear. If the edema is generalized edema, you need to consider what causes, if accompanied by increased protein in the urine, that is to say, the urine foam increases in the morning, in a short period of time does not disappear, it may be kidney disease. If accompanied by edema or high blood pressure can be considered hypertensive disorders of pregnancy, you need to pay close attention to the condition of the kidneys as well as the condition of the fetus, in order to avoid the occurrence of serious fetal dysplasia or stillbirth. If there is increased foaming in the urine, accompanied by edema, it is necessary to do a routine urinalysis to rule out the presence of protein in the urine, because increased foaming in the urine can be seen not only protein, but also increased glucose in the urine, and careful differential diagnosis is needed.
