That is what makes it easy to miss. Instead of waiting for symptoms, it helps to know your risk factors and ask your doctor for a simple blood sugar test, such as an A1C or a fasting glucose test. If you have insulin resistance or prediabetes, the good news is that steady changes in food, activity, sleep, and weight can lower your chance of getting type 2 diabetes. This article explains what insulin resistance is, who is most at risk, how it is found, and what you can do about it. ## What Is Insulin Resistance? Insulin is a hormone that helps move sugar from your blood into your cells for energy. With insulin resistance, your cells do not respond to insulin as well as they should. Your body makes more insulin to keep up. Over time, it may not be able to keep up, and blood sugar starts to rise. When blood sugar is higher than normal but not high enough to be diabetes, it is called prediabetes. The CDC says [more than 2 in 5 American adults have prediabetes](https://www.cdc.gov/diabetes/prevention-type-2/prediabetes-prevent-type-2.html) . ## Insulin Resistance Early Signs: Why Risk Factors Matter More The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) says in its [guide to insulin resistance and prediabetes](https://www.niddk.nih.gov/health-information/diabetes/overview/what-is-diabetes/prediabetes-insulin-resistance) that insulin resistance usually has no symptoms. So the best “early warning” is knowing whether you have risk factors. ### Common risk factors The NIDDK lists these as factors that raise your chance of insulin resistance and prediabetes: - Having overweight or obesity, or a large waist - Being age 35 or older - Having a parent, brother, or sister with diabetes - Being African American, American Indian, Asian American, Hispanic, Latino, or Pacific Islander - Not being physically active - Smoking or being around secondhand smoke - Having had diabetes during pregnancy, or a baby who weighed 9 pounds or more - Having polycystic ovary syndrome (PCOS) - Having sleep apnea - Taking certain medicines over time, such as steroids called glucocorticoids, some antipsychotics, and some HIV medicines If two or more of these fit you, it is worth asking your doctor about testing at your next visit. ## How Prediabetes Is Found Doctors do not usually test for insulin resistance itself in routine care. Instead, they check blood sugar. The NIDDK lists these ranges for prediabetes: | Test | What it shows | Prediabetes range | | --- | --- | --- | | A1C | Your average blood sugar over the past 3 months | 5.7% to 6.4% | | Fasting plasma glucose | Your blood sugar at the time of the test, taken after fasting | 100 to 125 mg/dL | | Oral glucose tolerance test | How your body handles a sugary drink | 140 to 199 mg/dL | Only your doctor can order and explain these tests. Ask for a copy of your results so you can track them over time. ## What You Can Do About It Large studies show that lifestyle changes can make a real difference. In the Diabetes Prevention Program, people at high risk who lost 5 to 7 percent of their starting weight lowered their chance of getting diabetes. For a 200-pound person, that is about 10 to 14 pounds. The CDC also recommends at least 150 minutes a week of activity like brisk walking. That is about 30 minutes a day, five days a week. ### Food habits that help - Build a balanced plate. Fill half with non-starchy vegetables, a quarter with protein, and a quarter with whole grains or starchy foods. - Pair carbs with protein or fiber. An apple with peanut butter is steadier than an apple alone. - Drink water instead of sweet drinks. Soda, sweet tea, and juice raise blood sugar fast. - Choose whole grains. Oats, brown rice, and beans digest slower than white bread and white rice. - Do not skip meals. Regular meals help avoid big swings and late-night overeating. The CDC has more practical tips on [healthy eating, meal planning, and reading food labels](https://www.cdc.gov/diabetes/healthy-eating/index.html) . ### Beyond the plate - Move more. A short walk after meals is an easy place to start. - Sleep well. The NIDDK lists getting enough sleep as one of the habits that can help. - Manage stress. Find something that helps you unwind, such as a walk, prayer, or time with friends. - Quit smoking. Ask your doctor about support to help you quit. ### Why these habits help Each of these habits works on the same problem from a different angle. Moving your muscles helps them use sugar from your blood. Fiber and protein slow down how fast sugar enters your blood after a meal. Cutting sweet drinks removes one of the fastest sources of sugar. Good sleep matters too, since poor sleep can make it harder for your body to manage blood sugar. Losing even a modest amount of weight can lower the strain on your body. Together, these small steps add up. The best plan is one you can keep. Start with one or two changes, such as a daily walk and swapping soda for water. Once those feel normal, add another. Ask your doctor to recheck your blood sugar at your next visit so you can see your progress. ## Medicine Is Your Doctor’s Call Some people with prediabetes or diabetes need medicine. That decision belongs to you and your doctor. If you already take medicine for blood sugar, keep taking it as prescribed. Food changes can lower blood sugar, so tell your doctor before you make big changes to your diet. Your doctor may need to watch your numbers more closely. Never start, stop, or change any medicine without talking with your prescribing doctor. Our clinic works alongside each patient’s medical doctors. We do not prescribe medication. ## Know the Signs of High Blood Sugar Prediabetes usually has no symptoms. The NIDDK notes that some people may have symptoms like those of diabetes. Call your doctor if you notice signs that blood sugar may already be high, such as being very thirsty, peeing often, blurry vision, sores that heal slowly, or losing weight without trying. ## Take the First Step in League City At Living Well Clinical Nutrition Center, we help people across League City and Bay Area Houston build food habits that support steady energy and healthy blood sugar.
