Low Blood Pressure

Low blood pressure, or hypotension, is a condition in which the pressure of the blood pushing against artery walls is lower than normal. This condition can be caused by a variety of factors, including dehydration, certain medications, or an underlying medical condition. Low blood pressure can cause symptoms such as lightheadedness, dizziness, blurred vision, fatigue, and shortness of breath. In some cases, low blood pressure can be a sign of a medical emergency and requires immediate medical attention. Low blood pressure occurs when the force of blood flow through the arteries is lower than normal. This force is created by the heart pumping blood through the arteries, and the pressure is determined by the amount of blood the heart pumps, the size of the arteries, and the amount of resistance the arteries provide. Low blood pressure can be caused by a decrease in the heart's pumping ability, an increase in the size of the arteries, or an increase in the resistance of the arteries. It can also be caused by certain medications or underlying medical conditions. Treatment for low blood pressure depends on the underlying cause. In some cases, lifestyle changes such as increasing water intake and avoiding certain medications can help. In other cases, medications may be prescribed to help regulate blood pressure.
