My daughter in law had a baby 12 weeks ago.  She developed high blood pressure and fluid in the lungs, shortness of breath after 2 weeks of giving birth.She was hospitalized for 4 days.  She still has a hard time breathing and high blood pressure and low heart rate.  She began to vomit today and is light headed.  Im concerned.  Thank you!
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of postpartum dilated cardiomyopathy (DCM) is more likely. It is cardiac complication seen after delivery. It causes poor pumping of heart. So heart rate is low and fluid tend to accumulate in lungs (Pulmonary edema). This in turn causes breathlessness and chest pain. So better to consult cardiologist and get done ECG and 2d echo. She may need diuretics and other cardiac supportive Chat Doctor.  Hope I have solved your query. I will be happy to help you further. Wishing good health to your daughter-in-law. Thanks.
