Symptoms that indicate unsafe or dangerous blood pressure levels during pregnancy, particularly relating to high blood pressure and preeclampsia, include:
- Persistent severe headache that does not go away
- Swelling of the face, hands, or feet that is sudden or severe
- Sudden weight gain that may point to fluid retention
- Vision changes such as blurred vision, seeing spots, flashing lights, or light sensitivity
- Upper abdominal or shoulder pain (usually under the ribs on the right side)
- Nausea or vomiting, particularly after mid-pregnancy
- Difficulty breathing or shortness of breath
- High blood pressure readings, especially systolic above 160 mm Hg or diastolic above 110 mm Hg, measured on two occasions
- Protein in the urine, indicating possible kidney problems (usually diagnosed by a doctor)
- Reduced urine output or swelling of the legs due to fluid buildup
- Sudden onset of severe fatigue, confusion, or altered consciousness (in severe cases or eclampsia)
- Seizures (a medical emergency indicating eclampsia)
These symptoms can signal preeclampsia or other hypertensive disorders of pregnancy which require immediate medical attention to prevent serious complications for both mother and baby.
It is critical for pregnant women to have regular prenatal checkups to monitor blood pressure and report any of these symptoms promptly to their healthcare provider for evaluation and management.
