Immunity is the body's own defense mechanism, which is the body's ability to recognize and destroy foreign invasion of viruses, bacteria and other bacteria, including cellular immunity and humoral immunity.
In addition, immunity can also refer to the body's ability to deal with aging, damage, death, and degeneration of its own cells, while recognizing and dealing with mutant cells and virus-infected cells in the body.
The human body can only maintain a healthy body when the immune system is functioning normally, and once the symptoms of decreased immunity appear, it is very good. It is susceptible to foreign viruses and bacteria that can lead to infectious diseases or other more serious diseases.
In order to reverse the trend of declining immunity, many people think of using immunity as a good friend and good helper - medicine. In fact, it is futile to use drugs to improve immunity, so far, no drugs can improve immunity, but some drugs will also lower immunity, why is this?
Although taking medicine will help the body resist external evils, but it will also produce side effects, because drug metabolism needs to be metabolized by the liver and kidney organs, and then enter the blood to play a role, so taking medicine for too long may lead to liver and kidney overload work, long-term will cause damage to the liver and kidneys, when toxic side effects accumulate to a certain extent, it will cause damage to human immunity.
Long-term use of antibiotics with antibacterial effect will cause antibiotics to kill normal white blood cells and then lead to a decline in the body's immunity, so when the condition is not serious, generally do not eat drugs that are harmful to the body, so as to prevent the body's defense ability from being reduced.
Why can't you take the 4 common medicines at home? Doctors warn: may destroy immunity
1. Analgesic drugs
Analgesic drugs commonly used is ibuprofen, it can treat a variety of pain, such as dysmenorrhea, headache, joint pain and tooth pain, if you take such drugs for a long time, can destroy immune cells, reduce immunity, when some parts of the body pain and repeated attacks, can not abuse this painkiller, should go to the hospital as soon as possible for relevant examinations.
2. Aspirin
Aspirin is often used to relieve cold symptoms and protect cardiovascular drugs, especially cardiovascular patients, who need to take aspirin for a long time to fight blood clotting to avoid thrombotic diseases.
But this medicine long-term eating is easy to cause gums, urine or gastrointestinal bleeding, blood is the carrier of human nutrition, the existence of immunity depends on the moisture of blood, if anemia or infection occurs, the damage to immunity can be imagined.
3. Glucocorticoids
Glucocorticoid drugs such as semisone, prednisone, hydrocortisone, etc., are glucocorticoids, which inhibit the inflammatory response in the human body at the same time, but also inhibit immune function, and will also affect immunity over time.
Glucocorticoids play a major role in the treatment of various systemic diseases, but they also inhibit the function of the patient's autoimmune system, for example, most patients with kidney disease have clinical hypoproteinemia, hypocomplementemia, insufficient nutritional intake, digestive tract absorption disorders, etc., which increase the chance of infectious complications in patients.
4. Compound licorice tablets
Long-term use of compound licorice tablets may also reduce the body's immunity, since the main ingredient of this medicine is glycyrrhizic acid, which is used to suppress coughs. However, if taken for a long time, the drug will be converted to glycyrrhetinic acid by intestinal bacteria after entering the body, and glycyrrhetinic acid will inhibit 11-β. The activity of HSD2 increases the level of cortisol in the body.
When cortisol exceeds 100 times the level of aldosterone, it is easy to cause hypokalemia, and potassium can maintain cell metabolism, regulate the body's acid-base balance, once the body is deficient in potassium for a long time, the body's pH will be unbalanced, and then it will lead to the occurrence of problems such as decreased immunity.
What are the precautions when taking medication?
1. Take it under the guidance of the instructions
Regardless of what drug you take, read the instructions for such drugs, because the instructions have a complete explanation of such drugs.
There are many contraindications to this drug, if this drug is marked with the sign of caution for people with liver and kidney insufficiency, it means that such drugs have certain damage to the kidneys and liver, and then choose as appropriate to see whether to take such drugs.
2. The dose should not be increased arbitrarily
When some people are sick and take medicine, they often have to exceed the dose specified by the doctor, thinking that "if you take more medicine, the disease will get better quickly". In fact, the speed of recovery does not depend on the amount of medication. On the contrary, if you arbitrarily increase the amount of medication, not only can not cure the disease, but it is prone to problems.
Because there is a certain limit to the absorption of drugs in the intestine, the large dosage is only to increase excretion. According to statistics, more than 90% of the adverse reactions caused by patients after taking drugs are caused by overdose.
2. Mistaking antibiotics for anti-inflammatory drugs
Anti-inflammatory drugs are simply used to deal with inflammation, such as redness, swelling, heat, pain; Antibiotics, on the other hand, are specifically designed to deal with inflammation caused by bacterial infections, and most people confuse the two, so that antibiotics are misused.
For some "inflammation" caused by non-bacterial infections, such as the common cold, flu, common diarrhea, and certain gynecological inflammations, antibiotics are not needed.
