These medications include metformin, SGLT-2 inhibitors and DPP4 inhibitors.Īlthough you may think you’ll know from experience when your blood sugar is out of whack, regular monitoring is the only way to truly make sure. They may or may not need adjustment, depending on how much you’re eating. Other medications: There are some diabetes medications that will lower your blood sugar when high, but won’t normally cause hypoglycemia.Long-acting insulin: The dosage for long-acting insulin is not usually based on food intake, so your doctor will not likely recommend a dose reduction.Mealtime insulin: For mealtime insulin, if you skip the meal, you should also forego the mealtime insulin.
Meanwhile, here are some general guidelines: If you find that you’re eating less due to an illness or other factors, your medications may need adjusting, so it’s important to talk to your doctor. Controlling diabetes when you’re not hungry “When you have diabetes and are acutely ill, you should check your blood sugars up to four times per day, drink plenty of fluids and contact your doctor if your blood sugars are consistently over 250,” Garvey says. If you’re not eating due to an acute illness like the flu or an infection, it’s also common for your blood sugars to rise. “Be ready to check your blood sugar and eat or drink 15 grams of simple sugar such as glucose tablets or 4 ounces of juice to correct a low blood sugar if needed.” This treatment is also recommended for Type 1 diabetes, she says. “It’s important to be aware of the symptoms associated with low blood sugars,” says Garvey. This medication doesn’t typically cause hypoglycemia. If your only treatment is metformin, you may not need to check your blood sugar more than once a day. “It’s important to keep in mind that sulfonylureas may cause your blood sugar to drop during the day if you don’t eat anything after taking your medication,” Garvey says. Those symptoms include:įor Type 2 diabetes: If you’re taking a sulfonylurea medication, check your blood sugars at least twice a day - in the morning and at bedtime. How often depends on whether you have Type 1 or Type 2 diabetes and what medications you take.įor Type 1 diabetes: Be sure to monitor your blood sugar before meals and before bedtime, typically four times per day, says Garvey.īeyond that, check your blood sugars if you notice symptoms of low blood sugar. When you’re ill or just don’t feel like eating much, it’s important to monitor your blood sugar levels more closely than ever. “If you’re just not up to eating on a regular schedule, talk to your doctor about diabetes medications that won’t cause low blood sugars,” she says. “If you take medications for diabetes that can cause low blood sugars, you should try not to skip meals,” says Garvey. However, even an occasional missed meal can throw off the balance between food intake and certain diabetes medications.The result is blood sugars that are too low (hypoglycemia) or too high (hyperglycemia) - and that can be dangerous.
