1. In the treatment of diseases, glucose is mostly made into solution dosage form for intravenous injection to help those patients who can't eat normally or have hypoglycemia to supplement sugar and increase energy. However, for a person with a normal diet, it is completely unnecessary to take medical glucose regularly. There is not much difference between glucose and ordinary sugar, except that the former is a decomposed monosaccharide, which can be directly absorbed through the intestine, while ordinary sugar must be digested and decomposed into monosaccharides before it can be used, but both of them have the same effect on the human body.
2. Many people will take it for granted that glucose can be directly absorbed into the blood without going through the digestion step, which is definitely more beneficial to the body, so they will take glucose orally for a long time. Actually, this is a misunderstanding. Long-term use of glucose will make the human stomach dependent and make the normal digestive function decline. Because the human small intestine directly absorbs glucose for a long time, the function of normal secretion of amylase and other digestive enzymes in the intestine will deteriorate, resulting in a decrease in the secretion of digestive enzymes such as amylase in the intestine, which will affect the normal digestion and absorption of other foods and easily lead to malnutrition and decreased resistance.
3. In addition to the sugar obtained from food every day, if you eat medical glucose in addition, especially in the long run, it will not only lead to excessive sugar intake, but also lead to anorexia, partial eclipse, dental caries, obesity and other adverse consequences, and also lead to low blood potassium, resulting in anorexia, fatigue, listlessness, palpitations and other symptoms. This is because too much sugar needs the participation of potassium ions in the process of synthesizing glycogen in the human body, and potassium ions in the blood will enter the cells with glucose, thus causing the decrease of serum potassium. Potassium is an indispensable macroelement in human body, whose main function is to maintain the acid-base balance of body fluids, participate in energy metabolism and the transmission of nerve impulses. When blood potassium is low, people will feel a series of discomfort.
4. If the concentration of medical glucose used is not properly diluted, for example, in the study of glucose tolerance test and clinical nursing observation, it is found that many subjects have different degrees of adverse reactions after taking glucose orally, such as nausea, vomiting, acid regurgitation, gastrointestinal discomfort, stomach pain, hunger, dizziness, headache, palpitation, sweating, fatigue, etc., and some subjects even have more.
5. Gastrointestinal reaction is caused by high-concentration sugar solution rapidly entering the stomach. If it is used on an empty stomach, hypertonic sugar solution will obviously increase the gastric content in a short time, which will cause gastric peristalsis and gastric contraction through nerve reflex, and some subjects will have discomfort symptoms such as nausea and vomiting after taking sugar. In addition, after healthy people take a large amount of hypertonic glucose quickly, the glucose is absorbed too fast, and the rapid increase of blood sugar stimulates cells to secrete excessive or relatively excessive insulin, resulting in idiopathic functional hypoglycemia and mild sympathetic nerve excitement.
6. In addition, uncontrolled diabetic ketoacidosis, hyperglycemic non-ketotic hyperosmotic state, and glucose-galactose malabsorption are all taboo, not to mention long-term use. In addition, most gastrectomies are prone to dumping syndrome when they take high concentration of sugar orally.
