What are the symptoms of high blood sugar after a meal

The typical symptoms of diabetes are obesity and unstable blood sugar levels, which are sometimes high and sometimes low, and require medication to control. In addition, most diabetics have high blood sugar levels after meals, and it is easy for them to ignore this symptom, causing certain risks. In fact, this is very incorrect. What are the general symptoms of high blood sugar after meals? Let’s take a look at the explanation below.

1) Polyuria: The urine volume reaches 3000-5000 ml or even more every night. The frequency of urination also increases, and you may urinate once every one or two hours. The higher the blood sugar, the more urine sugar is excreted and the more urine is produced.

2) Polydipsia: Intracellular water shortage caused by high sugar environment; excessive water loss due to polyuria, resulting in thirst and polydipsia. The more you urinate, the more water you drink, forming a proportional relationship.

3) Overeating: Due to the large amount of sugar excretion, cells are in a state of lack of energy and therefore need to be supplemented, which increases appetite. High blood sugar stimulates insulin secretion, which also makes patients prone to hunger. Both increase the patient's appetite and make them always feel full.

4) Weight loss: A large amount of adipose tissue is broken down to replace the lack of energy, resulting in weight loss in patients. The symptoms are less obvious in patients with atypical or mild diabetes. Some patients have normal fasting blood sugar, but high blood sugar and urine sugar after meals. These patients do not have serious glucose metabolism disorders, and they do not have obvious "three mores and one less". Some patients have a high renal glucose threshold. Although they have fasting hyperglycemia or obvious diabetic microangiopathy, they do not have glycosuria. Although some patients do not have typical symptoms, they have already developed peripheral neuropathy, large blood vessel lesions, etc.

Most of these patients will not take the initiative to go to the hospital for treatment. Some patients, although they have symptoms, ignore them themselves, mistakenly believing that polydipsia and polyuria are their habits rather than diseases; polyphagia is considered to be a good appetite and a sign of good health; weight loss is explained as being too busy at work, etc. These patients are often found to have high blood sugar and are subsequently diagnosed with diabetes only after a period of time or even several years when they go to the hospital for examination due to vision loss, edema, proteinuria, foot ulcers, periodontitis or urinary retention. At this time, complications harm yourself and your friends around you.
