Increased dimer needs to be given anticoagulant treatment, you can usually hang up internal medicine, if pregnant women hang up obstetrics and gynecology. Elevated dimer is generally due to excessive dissolution of fibrinogen or hypercoagulable state in the body, under normal circumstances, pregnancy or chronic kidney disease, myocardial infarction, cerebral infarction and other diseases will cause increased dimer. When the body is in a state of hypercoagulability, it is easy to form blood clots, therefore, if the dimer is elevated, it is necessary to give anticoagulant treatment, such as oral aspirin enteric-coated tablets or subcutaneous injection of low molecular heparin sodium, and so on. If the dimer is simply elevated during pregnancy it usually does not need to be treated. No matter what medication is used, patients should not blindly use medication privately, and must use medication under the guidance of a doctor. If the patient has an elevated dimer, she must go to the internal medicine department or obstetrics and gynecology department of the hospital as soon as possible.
