Queasiness and feeling like throwing up. Nausea is definitely a possible symptom of this condition, but not all of those who suffer from hypertension will experience nausea. Frequent nausea that has no plausible or obvious reason is definitely something to take seriously and to visit your doctor about. Remember that hypertension is a serious long-term health risk and that early detection and treatment can prevent permanent damage to your health.
Alcoholism. While alcoholism cannot really be called a symptom of hypertension, it certainly is something that increases the risk of developing the same. According to the criteria of the American Heart Association, a man should imbibe less than two drinks daily, and a woman, just one. Any adult who takes in more than that limit at one time will immediately see a temporary increase in blood pressure. Outright alcoholism is certainly an extremely high-risk factor and will almost always lead to long-term hypertension.
