Hi, I understand your concern. Yes, you need to take few precautions to prevent preeclampsia this time. - Inform your treating gynecologist about your past history, during your 1st visit to the doctor. - Have a regular monthly check up/ earlier check ups if advised so, through out your pregnancy. - Measurement of weight / blood pressure & urine routine & microscopic ( specially albumin) minimum monthly is of utmost importance, -Stick to the medicines ( pills to control BP as per need/ Tab Disprin half a day to prevent untoward effects of high BP.)/ diet restrictions advised by your doctor, - avoid physical/psychological stress. Be positive, - regular light exercises like walking are important. - Raised BP should be noted the earliest --which can be controlled to safe level by lifestyle changes & medicines. - Inform your doctor about swelling on legs if it occurs. - Once all the precautions are taken,patient can be relaxed , tension free.. as any first sign is caught5 earliest & treated. Thanks.
