Can Low Blood Pressure Cause Fatigue?

Andre Stone | MD

Yes, low blood pressure can definitely cause fatigue. Blood pressure below 90/60 mmHg is often described as low, but it does not always cause symptoms. In some people, low blood pressure can reduce blood flow enough to cause tiredness or weakness. Fatigue can occur when low blood pressure reduces the amount of blood reaching the brain and other parts of the body. Common symptoms accompanying low blood pressure fatigue include dizziness, lightheadedness, and difficulty concentrating. The fatigue is often most noticeable when standing up quickly or after prolonged periods of sitting or lying down. If you're experiencing persistent fatigue alongside other hypotension symptoms, it's important to consult with a healthcare provider to determine the underlying cause and appropriate treatment options.
