Hypertension complications are the symptoms of other diseases that patients get due to hypertension and some complications. Hypertension can damage the heart to a certain extent, which in turn causes the body’s immunity to decline, and leads to complications that are mostly symptoms of heart disease, such as angina pectoris and atherosclerosis. When a patient feels severe headache, vomiting, difficulty in breathing, or palpitations, he or she should promptly rest in bed and go to the hospital for related treatment as soon as possible. Hypertension belongs to a disease that can be controlled but will not be cured, so one can only be fully prepared for prevention to prevent its complications. Avoid overexertion and emotional excitement in normal daily life, and prohibit smoking, drinking and stimulating beverages.
