Blood Sugar Levels Chart !FREE!
If you have diabetes, your doctor may ask you to keep track of your blood sugar by testing it at home with a special device called a blood glucose monitor or home blood sugar meter. It takes a small sample of blood, usually from the tip of your finger, and measures the amount of glucose in it.

Your doctor will tell you when and how to test your blood sugar. Each time you do it, log it in a notebook or online tool or in an app. The time of day, recent activity, your last meal, and other things can all affect whether a reading will be of concern to your doctor. So try to log relevant information like:
Managing type 1 and type 2 diabetes well can delay or prevent complications that affect your eyes, kidneys, and nerves. Diabetes doubles your risk for heart disease and stroke, too. Fortunately, controlling your blood sugar will also make these problems less likely.
Keeping your blood sugar levels within the range recommended by your doctor can be challenging. That's because many things make your blood sugar levels change, sometimes unexpectedly. Following are some factors that can affect your blood sugar levels.
Learn about carbohydrate counting and portion sizes. A key to many diabetes management plans is learning how to count carbohydrates. Carbohydrates often have the biggest impact on your blood sugar levels. For people taking mealtime insulin, it's important to know the amount of carbohydrates in your food, so you get the proper insulin dose.
Some carbohydrates, such as fruits, vegetables and whole grains, are better for you than others. These foods are low in carbohydrates and have fiber that helps keep your blood sugar levels more stable. Talk to your doctor, nurse or dietitian about the best food choices and the appropriate balance of food types.
Avoid sugar-sweetened beverages. Sugar-sweetened beverages tend to be high in calories and offer little nutrition. And because they cause blood sugar to rise quickly, it's best to avoid these types of drinks if you have diabetes.
The exception is if you are experiencing a low blood sugar level. Sugar-sweetened beverages, such as soda, juice and sports drinks can be used as an effective treatment for quickly raising blood sugar that is too low.
Check your blood sugar level. Check your blood sugar level before, during and after exercise, especially if you take insulin or medications that lower blood sugar. Exercise can lower your blood sugar levels even up to a day later, especially if the activity is new to you, or if you're exercising at a more intense level. Be aware of warning signs of low blood sugar, such as feeling shaky, weak, tired, hungry, lightheaded, irritable, anxious or confused.
If you use insulin and your blood sugar level is below 90 milligrams per deciliter (mg/dL), or 5.0 millimoles per liter (mmol/L), have a small snack before you start exercising to prevent a low blood sugar level.
Insulin and other diabetes medications are designed to lower your blood sugar levels when diet and exercise alone aren't sufficient for managing diabetes. But the effectiveness of these medications depends on the timing and size of the dose. Medications you take for conditions other than diabetes also can affect your blood sugar levels.
When you're sick, your body produces stress-related hormones that help your body fight the illness, but they also can raise your blood sugar level. Changes in your appetite and normal activity also may complicate diabetes management.
Stick to your diabetes meal plan. If you can, eating as usual will help you control your blood sugar levels. Keep a supply of foods that are easy on your stomach, such as gelatin, crackers, soups and applesauce.
Drink lots of water or other fluids that don't add calories, such as tea, to make sure you stay hydrated. If you're taking insulin, you may need to sip sugar-sweetened beverages, such as juice or a sports drink, to keep your blood sugar level from dropping too low.
The liver normally releases stored sugar to counteract falling blood sugar levels. But if your liver is busy metabolizing alcohol, your blood sugar level may not get the boost it needs from your liver. Alcohol can result in low blood sugar shortly after you drink it and for as long as 24 hours afterward.
If you're stressed, the hormones your body produces in response to prolonged stress may cause a rise in your blood sugar level. Additionally, it may be harder to closely follow your usual diabetes management routine if you're under a lot of extra pressure.
Type 2 diabetes is usually diagnosed using the glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. Results are interpreted as follows:
Random blood sugar test. Blood sugar values are expressed in milligrams of sugar per deciliter (mg/dL) or millimoles of sugar per liter (mmol/L) of blood. Regardless of when you last ate, a level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes, especially if you also have signs and symptoms of diabetes, such as frequent urination and extreme thirst.
Oral glucose tolerance test. This test is less commonly used than the others, except during pregnancy. You'll need to fast overnight and then drink a sugary liquid at the doctor's office. Blood sugar levels are tested periodically for the next two hours. Results are interpreted as follows:
Exercise is important for losing weight or maintaining a healthy weight. It also helps with regulating blood sugar levels. Talk to your primary health care provider before starting or changing your exercise program to ensure that activities are safe for you.
Limit inactivity. Breaking up long bouts of inactivity, such as sitting at the computer, can help control blood sugar levels. Take a few minutes to stand, walk around or do some light activity every 30 minutes.
Weight loss results in better control of blood sugar levels, cholesterol, triglycerides and blood pressure. If you're overweight, you may begin to see improvements in these factors after losing as little as 5% of your body weight. However, the more weight you lose, the greater the benefit to your health and disease management.
Your health care provider will advise you on how often to check your blood sugar level to make sure you remain within your target range. You may, for example, need to check it once a day and before or after exercise. If you take insulin, you may need to do this multiple times a day.
Monitoring is usually done with a small, at-home device called a blood glucose meter, which measures the amount of sugar in a drop of your blood. You should keep a record of your measurements to share with your health care team.
If you can't maintain your target blood sugar level with diet and exercise, your doctor may prescribe diabetes medications that help lower insulin levels or insulin therapy. Drug treatments for type 2 diabetes include the following.
DPP-4 inhibitors help reduce blood sugar levels but tend to have a very modest effect. Examples include sitagliptin (Januvia), saxagliptin (Onglyza) and linagliptin (Tradjenta). Possible side effects include:
GLP-1 receptor agonists are injectable medications that slow digestion and help lower blood sugar levels. Their use is often associated with weight loss, and some may reduce the risk of heart attack and stroke. Examples include exenatide (Byetta, Bydureon), liraglutide (Saxenda, Victoza) and semaglutide (Rybelsus, Ozempic). Possible side effects include:
Some people who have type 2 diabetes need insulin therapy. In the past, insulin therapy was used as a last resort, but today it may be prescribed sooner if blood sugar targets aren't met with lifestyle changes and other medications.
Different types of insulin vary on how quickly they begin to work and how long they have an effect. Long-acting insulin, for example, is designed to work overnight or throughout the day to keep blood sugar levels stable. Short-acting insulin might be used at mealtime.
Your doctor will determine what type of insulin is appropriate for you and when you should take it. Your insulin type, dosage and schedule may change depending on how stable your blood sugar levels are. Most types of insulin are taken by injection.
Regularly monitoring your blood sugar levels is important to avoid severe complications. Also, be aware of signs and symptoms that may suggest irregular blood sugar levels and the need for immediate care:
High blood sugar (hyperglycemia). Eating certain foods or too much food, being sick, or not taking medications at the right time can cause high blood sugar. Signs and symptoms include:
Hyperglycemic hyperosmolar nonketotic syndrome (HHNS). This life-threatening condition includes a blood sugar reading higher than 600 mg/dL (33.3 mmol/L). HHNS may be more likely if you have an infection, are not taking medicines as prescribed, or take certain steroids or drugs that cause frequent urination. Signs and symptoms include:
Low blood sugar. If your blood sugar level drops below your target range, it's known as low blood sugar (hypoglycemia). Your blood sugar level can drop for many reasons, including skipping a meal, unintentionally taking more medication than usual or being more physical activity than usual. Signs and symptoms include:
Many alternative medicine treatments claim to help people living with diabetes. According to the National Center for Complementary and Integrative Health, studies haven't provided enough evidence to recommend any alternative therapies for blood sugar management. Research has shown the following results about popular supplements for type 2 diabetes:
When providing nutrition advice to patients with prediabetes, the foods that can increase blood-glucose levels are often not what you think. Identifying those foods are key to helping patients take the right step toward healthier eating.
