During the holiday season, many patients are unable to resist the temptation of food, and their blood sugar tends to fluctuate because of various reasons such as irregular work and rest time. After the festival, patients realize that they should control their blood sugar, but due to the eagerness to reduce sugar or take it for granted, it is easy to enter various misconceptions of post-holiday sugar control. Myth 1: No discomfort and thus no attention. Many patients mostly rely on their feelings when facing the disease, and if they don’t feel uncomfortable, they won’t feel that their body is malfunctioning. However, diabetes is a digital disease, and it must be monitored by blood glucose in order to understand the changes in the disease. Many patients have no symptoms of three more or less in the early stage of the disease, and when symptoms such as eye discomfort or problems with nerve endings appear, the condition is already more serious. Therefore, for diabetic patients and people at risk of diabetes, regardless of whether they are uncomfortable after the holidays, they should go to the hospital endocrinology specialist to do a comprehensive examination, and usually strengthen blood sugar monitoring, after all, irregular habits during the holidays can have a negative impact on blood sugar. Myth 2: Reduce diet after the festival to make up for the mistake of eating and drinking during the festival. As many people gorge themselves during the festival, once they arrive after the festival, they realize that they should control their diet, so they suddenly reduce their food intake or eat vegetarian dishes completely. Therefore, the post-holiday diet should still maintain a balanced diet with exercise and medication to ensure the stability of blood sugar. Myth 3: Increase the amount of exercise to lower blood sugar. As the saying goes, too much is too little, as well as the sudden reduction of diet, high-intensity exercise will make the blood sugar drop rapidly, but the drop too fast will appear hypoglycemia, and not exercise during the holiday season, suddenly increase the intensity of exercise after the holiday, which makes the patient’s body will also feel uncomfortable, when the strenuous exercise will make the body produce a stress response, in order to adapt to these large amounts of strenuous exercise, some hormone levels in the body will rise In order to adapt to these large amounts of strenuous exercise, some hormone levels in the body will rise, among which there are hormones that fight with insulin, it will make blood sugar higher, especially some elderly people or patients with serious complications are also prone to accidents if they exercise too much. Therefore, even if there is no exercise during the holiday season and blood sugar is already elevated, diabetic patients should not be in a hurry, but still maintain a “calm” mentality and balance diet, exercise and medication. In addition, in terms of medication, medication adjustment should not be too fast, but should gradually increase the dose of hypoglycemic drugs according to the blood sugar level to avoid excessive blood sugar fluctuations. In conclusion, controlling blood sugar is not something that can be solved by which method of diet or exercise or medication, it needs five carriages driving side by side and in a balanced way, while maintaining a better state of mind and formulating scientific and reasonable post-holiday sugar control measures with the help of doctors. Only in this way can patients avoid entering the post-holiday sugar control misunderstanding, and blood sugar can be controlled within the normal range.
