Hypertension, also known as high blood pressure, is when the force of blood against the walls of the arteries is too powerful. This can lead to serious health problems, including heart disease, stroke, kidney disease, and other health issues. Regular blood pressure checks are important because high blood pressure doesn’t always cause symptoms. Dealing with hypertension can involve eating a healthier diet, exercising regularly, managing stress, and taking prescription medications.

FAQ
What are the symptoms of high blood pressure?
Someone can have high blood pressure for years with no symptoms at all, which is why it’s known as the “silent killer.” Severe hypertension may cause headaches, vision problems, shortness of breath, and nosebleeds.
What numbers indicate dangerously high blood pressure?
A blood pressure reading of 180/120 mm Hg or higher is considered a hypertensive crisis that requires immediate medical attention. Call 911 if there’s also chest pain, shortness of breath, vision changes, weakness, or speech difficulties.
What are the main causes of high blood pressure?
Many factors raise your risk of high blood pressure, including age, race, family history, and genetics. A poor diet, not exercising enough, chronic stress, heavy alcohol consumption, and smoking also increase your risk.
Can you cure high blood pressure?
There’s no cure for hypertension, but high blood pressure numbers can be effectively lowered with a combination of medication and healthy lifestyle choices, such as limiting salt, maintaining a healthy weight, and consistently getting enough sleep.
What foods should I avoid with high blood pressure?
Limit your intake of sodium, saturated and trans fats, red meat, processed foods, and added sugars. Instead choose fruits and vegetables, whole grains, low-fat dairy, skinless poultry and fish, nuts, and legumes.
