3. Difficulty Breathing

Difficulty breathing is often a sign of high blood pressure. When the heart has to work harder to pump blood through the arteries, it can cause them to narrow and put pressure on the lungs. This can make it difficult to breathe, especially during physical activity. If you experience shortness of breath, fatigue, or chest pain, it is important to see a doctor so that they can check your blood pressure and determine if you are at risk for hypertension.
