Ovarian foramen undulant does not cause high blood pressure. 1. Ovarian foramen undulant is a congenital heart lesion, which is the most common congenital heart anomaly in adults, and usually does not cause high blood pressure. Although this disease does not cause hypertension, it may cause headache, wheezing, dizziness, dyspnea, temporary aphasia and other symptoms, and in severe cases, it may even be complicated by unexplained migraine and stroke. 2. While the cause of hypertension is unknown, age, high sodium and low potassium diet, heredity, long-term mental stress, obesity, excessive alcohol consumption, endocrine diseases and so on are the risk factors for its development. Once found that the foramen ovale is not closed, it is recommended to go to the hospital in time, according to the doctor’s guidance for treatment, so as not to delay the condition and cause serious consequences.
