Many patients often stop taking their medication before attending health check-ups to ensure that they are “fasting”, but this is likely to lead to a relapse. The medical examination center experts and endocrinologists said that patients with chronic underlying diseases should not stop their medication before attending the health checkup, and other people should follow medical advice to see if they need to stop their medication. The purpose of the checkup depends on whether you need to stop the medication. Ms. Liu is a hypertensive patient, because she wants to participate in the unit’s annual health checkup, she stopped taking antihypertensive medication from the day before the checkup, but she did not expect the blood pressure to rise abnormally immediately after the blood draw, which was almost dangerous. Many patients with chronic underlying diseases are aware of stopping their medication. In this regard, Professor Cheng Hua of the Department of Endocrinology at the Second Hospital of Sun Yat-sen University said that most patients with chronic diseases stop taking their medication during the health check-up because they are worried that taking the medication will affect the results of the check-up, while others want to see the status of their disease after not taking the medication and see if their disease is completely normal. Experts explain that the need to stop taking medication for medical checkups mainly depends on the purpose of the checkup. If it is a physical examination to see if the effect of the drug is working, it is not necessary to stop the drug; if it is to check whether the body is suffering from a certain disease, it should inform the doctor of the drug taken, and the doctor will decide whether to stop the drug. In the case of hypertension, for example, if the purpose of the examination is to evaluate the effectiveness of the treatment of hypertension medication, the medication should not be stopped before the examination; if the examination is to determine whether the patient is suffering from hypertension, other medications need to be temporarily stopped to avoid interfering with the results leading to misdiagnosis. Generally speaking, employees do not need to stop taking medication before routine medical examinations, especially for patients with chronic underlying illnesses, it is best not to stop taking medication without permission, otherwise serious consequences may occur. Whether you need to take medication also depends on whether the drug is short-acting or long-acting. If it is a short-acting drug, do not eat once, blood pressure will rise. If it is a long-acting drug, it does not matter if you miss one or two doses. The diabetic patient can’t take glucose-lowering drugs before testing fasting blood sugar, while blood pressure drugs have little effect. Patients with diabetes and hypertension, the night before the physical examination before taking glucose-lowering drugs and antihypertensive drugs, for the results of the day of the examination are not affected. “Especially antihypertensive drugs must be taken immediately after waking up in the morning, because blood pressure is generally higher in the morning, stop taking antihypertensive drugs, which can cause blood pressure abnormalities and lead to serious consequences, but whether or not to take antihypertensive drugs on the determination of blood glucose and blood pressure does not have a significant impact.” Zhang Jin said that the most common clinical practice is to check the postprandial blood sugar before the patient does not take medication, so that the results of the check, blood sugar is always high, can not correctly estimate the effect of treatment. For diabetic patients, it is often not drugs but food that affects the results of tests such as blood glucose, so it is important to fast before the physical examination. “This fasting does not mean that you can’t eat anything at all, you can drink a small amount of water. And fasting is not just not to eat breakfast, but to fast after 8 p.m. the night before the physical examination. Dinner should not be eaten too late, not to mention late night snacking.” Some patients are advised to take medication immediately after the physical examination Hypertensive patients should take antihypertensive medication before going to the hospital for physical examination, while diabetic patients and patients with coronary heart disease can bring their medication to the hospital and have their blood drawn on an empty stomach before taking their medication. If the unit physical examination are general routine items, the medicine taken by the patient will not have a serious impact on the results of blood sugar, blood lipids, liver and kidney function. However, if the examination is for a special project, the medical history and the medication taken should be told to the specialist, who will decide whether to discontinue it. “Because the physical exam reflects the current state, there is no need to stop the medication days or even weeks in advance. If you stop the medication without asking, it will definitely have an impact on your condition.”
