When someone has high blood pressure, the heart and arteries have a much heavier workload. The heart must pump harder and the arteries are under greater strain as they carry blood.</p> <p>Having high blood pressure puts someone at a higher risk for stroke, heart attack, kidney failure, loss of vision, and atherosclerosis (hardening of the arteries).</p> <p>There are two types of high blood pressure, or hypertension:</p> <ol class="kh_longline_list"> <li><strong>Secondary hypertension</strong> has a known cause, such as kidney disease, heart disease, or certain medications. Most young kids with high blood pressure have secondary hypertension.</li> <li><strong>Primary hypertension</strong> has no identifiable cause and is the most common cause of high blood pressure in older kids and adults. When school-age kids and teens have primary hypertension, it's usually linked to excess <a href="https://kidshealth.org/ws/RadyChildrens/en/parents/childs-weight.html/">weight</a>.</li> </ol> <p>Treatment for primary hypertension usually begins with lifestyle changes, including weight loss, regular exercise, reducing salt intake, and avoiding alcohol. If lifestyle changes alone aren't enough, a doctor may recommend medications to lower blood pressure. This type of treatment is usually reserved for severe cases of hypertension or those that cause symptoms such as headaches or seizures.</p> <h3>Keep in Mind</h3> <p>Untreated high blood pressure can eventually damage the heart, brain, kidneys, and eyes. But if it's caught early, monitored, and treated, those who have it&nbsp;can lead active, normal lives.</p> <p><em>All A to Z dictionary entries are regularly reviewed by KidsHealth medical experts.</em></p>
