Overview
Blood pressure is the force of blood pushing against the walls of the arteries. When it stays too high over time, it can strain the heart and damage blood vessels and organs such as the brain and kidneys. Blood pressure control focuses on prevention, early detection, and long-term management.
Key Symptoms
High blood pressure usually does not cause noticeable symptoms, which is why it is often called a silent condition. Some people only learn they have it during a routine checkup. Symptoms such as chest pain, severe headache, shortness of breath, confusion, weakness, or vision changes need urgent medical assessment.
Causes and Risk Factors
Blood pressure can rise because of a mix of age, family history, diet, body weight, stress, alcohol use, tobacco exposure, low physical activity, and certain health conditions. Too much sodium, poor sleep, and some medicines can also affect blood pressure. In some people, an underlying medical problem contributes to high blood pressure.
Who Is Affected
Blood pressure changes can affect adults worldwide, and risk often increases with age. However, younger adults can also have high blood pressure, especially if risk factors are present. During pregnancy, blood pressure changes need special medical attention.
Prevention
Many people can lower their risk by staying active, eating a balanced diet rich in fruits and vegetables, limiting salt, avoiding tobacco, and limiting alcohol. Managing stress, sleeping well, and keeping follow-up appointments also matter. Regular blood pressure checks help find problems early.
Diagnosis and Tests
Blood pressure is measured with a cuff placed around the arm. A healthcare professional may repeat readings over time or ask for home or ambulatory monitoring because blood pressure can vary during the day. Blood and urine tests or other checks may be used to look for causes of high blood pressure or signs of organ effects.
Treatment Categories
Treatment may include lifestyle changes, regular monitoring, and medicines prescribed by a healthcare professional when needed. Treatment plans depend on the blood pressure level, overall health, and whether there is damage to the heart, brain, kidneys, or blood vessels. It is important to follow medical advice and not stop prescribed medicine without guidance.
Diet and Lifestyle
Helpful habits often include eating more vegetables, fruits, legumes, and whole grains, and reducing foods high in salt. Regular movement, maintaining a healthy weight, avoiding smoking, and limiting alcohol can support blood pressure control. Home monitoring may help some people track patterns and share readings with their clinician.
When to Seek Medical Care
Seek medical care if blood pressure readings are repeatedly high, if you are pregnant and have concerns about blood pressure, or if you have side effects or questions about a treatment plan. Also seek care if you develop swelling, dizziness, fainting, or new symptoms that may be related to blood pressure or its treatment. Regular follow-up is important even when you feel well.
When It May Be an Emergency
Get emergency help right away for severe chest pain, trouble breathing, signs of stroke such as face drooping or trouble speaking, severe confusion, fainting, seizures, or sudden severe headache with very high blood pressure. These symptoms can signal a medical emergency and should not be ignored.
