The company’s main business is the development of a new product, a new product for the company. However, in recent times, every time after eating, Mr. Zhao has symptoms such as dizziness, panic, nausea, sweating, weakness and drowsiness of the limbs. He thought his old high blood pressure had returned and took more antihypertensive drugs, but the symptoms became more and more severe. His son took him to the hospital for a checkup, and he was diagnosed with “meal reaction” to hypertension in the elderly. The son had no choice but to take him to the hospital and he was diagnosed as having a “meal reaction” to hypertension. 1, what is hypertension “meal reaction”? Some elderly people with hypertension may experience dizziness, panic, weakness and cold sweat soon after eating. Some patients with the above symptoms, will think that the blood pressure is not well controlled, rushed to take additional antihypertensive drugs, in fact, this situation is not necessary to eat antihypertensive drugs, otherwise not only can not play the expected role, but also may lead to danger because of excessive lowering of blood pressure. 2, hypertension “meal reaction” is how to happen? As we all know, hypertensive patients need to medicine, regular life, not anxious, not angry, light diet, but such as Mr. Zhao hypertensive patients even if they strictly comply with the above “regulations”, but still appear dizziness, panic, weakness, cold sweat and other symptoms, and the strange thing is that these symptoms often occur when just after eating. What is the reason for this? The reason is that when normal people eat, the body can produce some peptide factors, growth hormone inhibitory factors and insulin and other substances, so that the abdominal organs vasodilatation, blood flow increases, blood pressure and blood sugar tend to reduce. For such changes, the body stimulates the pressure receptors located in the wall of the aortic arch, resulting in sympathetic excitation, increased secretion of adrenaline, enhanced heart contraction and faster heartbeat, compensating for the normal level of blood pressure and blood sugar. Therefore, normal people have no special discomfort. In contrast, most elderly hypertensive patients are accompanied by more obvious aortic sclerosis, resulting in blunted pressure receptor response and slower sympathetic nerve activity, which cannot physiologically regulate in a timely manner, resulting in a rapid drop in blood pressure and blood glucose, causing insufficient sugar and oxygen supply to the brain and heart, and then a series of meal reactions. The low blood sugar and blood pressure can even induce complications such as cerebral thrombosis, angina pectoris and myocardial infarction. If you take antihypertensive drugs on your own, as Zhao did, it is like “adding insult to injury”, the consequences are very dangerous. 3, how to prevent hypertension “meal reaction”? The elderly hypertension “meal reaction”, generally do not need special treatment. But should pay attention to the treatment of hypertension, adhere to the rules of taking antihypertensive drugs, in order to maintain the relative stability of blood pressure. In terms of prevention, the following measures can be taken: (1) In the daily diet, it is best to implement the system of eating less and more meals. Eat only 70% to 80% full at each meal, especially not too full at night. (2) The speed of eating should be slow, should be chewed and swallowed slowly, and the temperature of food should be moderate. (3) In terms of dietary structure, the ratio between protein, fat and carbohydrates should be appropriately increased, and some hot tea or coffee should be consumed before eating. (4) After exertion should take a short break before eating, should not get up immediately after the meal, should rest for an hour or more before activity. (5) The elderly who have the habit of drinking soup and tea should drink before meals, and the amount of each drink should not be too much, so as not to increase the feeling of abdominal fullness after meals, which can easily occur meal reactions. (6) Once syncope occurs, you should immediately lie down, head slightly lower and to the side to prevent vomit choking into the trachea, generally about 10 minutes, the symptoms can be relieved. If the dizziness, panic and weakness do not ease after a meal for a long time, or even vomiting, chest pain or transient fainting, it is not a symptom caused by meal reaction, and it is necessary to go to the hospital in time to avoid delaying the disease.
