Final answer:
Low blood pressure can cause symptoms such as dizziness and fainting, while high blood pressure can damage organs and increase the risk of heart attack and stroke.
Step-by-step explanation:
Low blood pressure is not usually a concern, as long as there are no problems associated with the low pressure. Symptoms associated with low blood pressure include dizziness or lightheadedness, fainting, dehydration and unusual thirst, lack of concentration, blurred vision, nausea, and fatigue.
High blood pressure, on the other hand, can have serious consequences. If blood pressure is too high, it can damage blood vessels and organs, increasing the risk of heart attack and stroke. Hypertension, or high blood pressure, is also a major risk factor for coronary artery disease, heart failure, and chronic kidney disease.
