Hypertension is a big word that means high blood pressure. Blood pressure is like the pressure of water in a hose. When you turn on a hose, the water comes out with pressure. Similarly, blood that must flow through our body also has pressure.
Blood pressure is important because it helps our body deliver nutrients and oxygen to different parts. However, if the pressure gets too high, it can hurt our body. That's why we need to check our blood pressure from time to time to make sure it's not too high.
If someone has hypertension, it means their blood pressure is too high, and it can lead to many health problems. Hypertension can cause our heart to work too hard, damage our blood vessels, and damage other organs in our body. We can keep our blood pressure in check by eating healthy food, exercising every day, and taking medicine prescribed by a doctor.
