1.Glucocorticoids In addition to dexamethasone mentioned above, glucocorticoids also include prednisone, prednisolone, hydrocortisone, betamethasone and so on. These drugs are mainly used to treat autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, dry syndrome, glomerulonephritis, nephrotic syndrome, etc. Generally speaking, the effect of glucocorticoids on blood glucose is transient and reversible, and as the dosage of hormones increases or decreases, blood glucose increases or decreases accordingly. When diabetic patients use the above mentioned drugs, they must consult their doctors and avoid them as much as possible unless necessary, especially they must avoid abusing hormones like Lao Zhang did. If combined with certain diseases must be applied, timely adjustment of hypoglycemic drugs, monitoring blood sugar, to avoid acute complications of diabetes such as diabetic ketoacidosis and hyperosmolar coma due to a sharp rise in blood sugar. 2, certain non-steroidal anti-inflammatory drugs such as acetaminophen in cold medicine, anti-platelet drugs such as aspirin. The metabolism of such drugs competes with the metabolism of commonly used oral hypoglycemic drugs including hypoglycemic, euglycemic and chlorosulfonylurea, which increases the concentration of hypoglycemic drugs in the body, strengthens the effect of hypoglycemic drugs and leads to lower blood sugar. Therefore, diabetic patients should closely monitor their blood sugar when taking these drugs initially to avoid inducing hypoglycemic coma, and the dose of hypoglycemic drugs should be adjusted if necessary. 3, certain antihypertensive drugs Many diabetic patients are combined with hypertension, unaware that some common antihypertensive drugs can affect blood sugar. For example, diuretics such as tachyphylaxis and dihydrocoumaric acid (one of the main ingredients of compound antihypertensive tablets) can raise blood sugar. And beta-blockers such as metoprolol and bisoprolol can both raise blood sugar and mask the symptoms of hypoglycemia in the process of lowering blood sugar, and should be taken with caution in diabetic patients. Calcium antagonists such as felodipine and nifedipine also have a slight effect of raising blood glucose. Angiotensin-converting enzyme inhibitors and angiotensin-converting enzyme receptor agonists, such as Irbesartan, Valsartan, Corsartan, Captopril, Enalapril, etc., have less effect on blood sugar and are preferred by patients with diabetes combined with hypertension. Certain antibiotics such as levofloxacin, gatifloxacin, moxifloxacin, lomefloxacin and other quinolone antibiotics for lung infection and urinary tract infection can disrupt insulin secretion and induce hypoglycemia or hyperglycemia, among which gatifloxacin and moxifloxacin are more serious and should be avoided as much as possible. The cephalosporin antibiotics have less effect on blood sugar and can be preferred by diabetic patients. 5, certain lipid-regulating drugs Diabetic patients often take oral lipid-regulating drugs due to combined hyperlipidemia, such as simvastatin, lovastatin, pravastatin, resulvastatin, atorvastatin, fluvastatin and so on. A recent study has shown that high doses of statin lipid-lowering drugs can raise blood sugar, while previous studies have demonstrated that regular doses of statin lipid-lowering drugs may cause diabetes in patients who do not have diabetes. Therefore, patients with diabetes should be cautious when choosing lipid-lowering drugs. Many of the medications mentioned above that may be commonly used by diabetics can affect blood sugar, which may confuse sugar lovers. Then how to control the high blood pressure and lipids? The answer is not to choke on them. As long as they communicate with a medical professional, evaluate the pros and cons of their use, and monitor their blood sugar closely during use, these medications can still be used safely.
