Some people will ask why they have to take medication for life when they have a chronic disease, and whether they will become addicted to taking it for a long time. To answer this question, let’s use an analogy: we have to eat every day for life, is it because we are addicted to eating? Not really, but we need it. Of course, comparing medicine to a meal is not appropriate enough, but here it can help people understand the need for long-term medication. There are many chronic clinical conditions, such as hypertension. Under normal conditions, blood flowing through blood vessels exerts a certain pressure on the walls of the vessels, i.e. blood pressure. Whether it is vascular sclerosis or vasoconstriction, it causes excessive pressure on the blood vessels and produces blood pressure. The continuous increase in blood pressure causes damage to the blood vessels and leads to diseases such as atherosclerosis, cerebrovascular accidents, kidney diseases, etc. It is also the main cause of stroke. It was not until the 1950s that various anti-hypertensive drugs were finally introduced. There are many types of antihypertensive drugs, all with different mechanisms of action. For example, antihypertensive drugs with “Pulley” or “Satan” in their names act on the blood pressure regulatory system of angiotensin II. Through the hormone system related to angiotensin II, the drug is involved in the regulation of blood pressure in the body, and as a result, blood pressure is lowered. However, the drug itself can only lower blood pressure, but it cannot eliminate the root cause of blood pressure increase, such as vascular sclerosis, narrowing of blood vessels, etc. Without the effect of the drug, blood pressure will continue to rise. Without the action of drugs, blood pressure will still not come down. It is not like other drugs that can get rid of the cause of the disease, such as antibiotics that kill the germs, the disease will be cured, and there is no need to treat with drugs afterwards. The problem of addiction. Addictive drugs are narcotic drugs and psychotropic drugs under special management by the state, with special labels and red prescriptions, and abuse becomes a drug, which is against the criminal law. In contrast, long-term drugs for chronic diseases, such as antihypertensive drugs, do not have the problem of addiction, so there is no need to worry. Many chronic diseases are affluenza and lifestyle diseases, which cannot be controlled by drugs alone. To control hypertension, you should pay attention to sleep, reduce the amount of salt, stay away from the stimulation of alcohol and tobacco, and exercise properly, all of which are beneficial to the disease, as well as potentially reducing the amount of medication taken.
