Cocaine use can temporarily cause hypertension. Caffeine may cause minor increases in blood pressure which last for a few hours. Cold remedies often contain substances that constrict blood vessels and may raise blood pressure. Temporary, but significant hypertension may develop during abrupt withdrawal from heavy alcohol consumption. Chronic alcohol use, especially in excess of two drinks per day, may elevate blood pressure and increases mortality.
Panic disorder can lead to episodic hypertension.
Chronic hypertension is high blood pressure that is present and observable before pregnancy or that is diagnosed before the 20th week of gestation. Several other safe medications that lower blood pressure are available and most women with hypertension have uneventful pregnancies as long as blood pressure is well controlled. This condition occurs after the 20th week of gestation, and is characterised by increased blood pressure, protein in the urine, swelling of the legs, and sometimes kidney and liver problems. Treatment for preeclampsia may include premature delivery of the baby. You can have a normal life despite having hypertension.
