Type 1 diabetes - self-care
Type 1 diabetes is a life-long (chronic) disease in which there is a high level of sugar (glucose) in the blood. If you have type 1 diabetes, your body makes little to no insulin. Insulin is a hormone made by the pancreas that controls blood sugar. Insulin lowers blood sugar by allowing it to leave the bloodstream and enter cells. Without enough insulin, glucose builds up in the bloodstream instead of going into the cells. This buildup can lead to high blood sugar (hyperglycemia).

Read Article Now Book Mark ArticleType 1 diabetes can occur at any age. It is most often diagnosed in children, teens, and young adults.
Everyone with diabetes should receive proper education and support about the best ways to manage their diabetes. Ask your health care provider about seeing a certified diabetes care and education specialist (often called a diabetes educator). Working with your diabetes care team can help you manage type 1 diabetes.
Symptoms of Type 1 Diabetes
Symptoms of type 1 diabetes can occur when your blood glucose levels go too high or too low.
HIGH BLOOD SUGAR
High blood sugar can occur for several reasons:
- You did not give yourself enough insulin
- You ate more than you planned to
- You have been less active than usual
- You are sick with an illness
- You are under stress
- Some medicines, such as steroids or certain mood-stabilizing agents, can cause your blood sugar to spike
Symptoms of high blood sugar include:
- High blood glucose readings
- High glucose in the urine
- Being very thirsty
- Urinating more often (including urinating at night or bedwetting in children who were dry overnight before)
- Feeling sluggish
- Blurred vision
LOW BLOOD SUGAR
Low blood sugar (hypoglycemia) can develop quickly in people with diabetes who are taking insulin. Symptoms usually appear when a person's blood sugar level falls below 70 milligrams per deciliter (mg/dL), or 3.9 millimoles per liter (mmol/L).

- Lightheadedness or dizziness
- Hunger
More severe symptoms include:
- Sleepiness
- Weakness
- Confusion
- Poor coordination
- Blurred vision
- Seizures
Practicing self-care can help you manage type 1 diabetes and help keep your blood glucose level in a healthy range.
Check Your Blood Sugar Regularly
People with type 1 diabetes need to check their blood sugar level at least 4 times a day. You can check your blood sugar at home using a blood glucose meter to track your glucose levels before, between, or after meals and at other times when needed. A continuous glucose monitor (CGM), is a device you can wear that will track your blood sugar in real time and give you updates.

Learn what to do if your blood sugar goes too high or too low. You can treat early signs of hypoglycemia at home by drinking orange juice, eating sugar or candy, or taking glucose tablets. If you experience high or low blood sugar very often, talk with your provider. You may need to make changes to your diabetes management plan.

Everyone with type 1 diabetes needs to take insulin every day. There are different types of insulin based on how fast they work, when they peak, and how long they last. Your provider will work with you to find the best types of insulin for you. Most people with type 1 diabetes take more than one type of insulin. You will also learn how and when to use insulin.

Meal Planning with Type 1 Diabetes
To help keep your blood sugar level in your target range, you will need to follow a meal plan. Meal planning helps you maintain a balance between your food and insulin intake. Testing your blood sugar helps you see how food can raise or lower your blood sugar.
Your meal plan should include:
- Food from all the food groups
- Few added sugars and processed foods
- More high-fiber foods

HOW CARBOHYDRATES AFFECT BLOOD SUGAR
Carbohydrates in food give your body energy. The main kinds of carbohydrates (commonly called "carbs") are starches, sugars, and fiber. Your body needs all types of carbs to function properly. Your body quickly turns starches and sugars into glucose for energy. This raises your blood sugar level. Fiber does not raise blood sugar. In fact, fiber can help you manage your blood glucose.

Carbohydrates are one of the main nutrients in our diet. They help provide energy for our body. There are three main types of carbohydrates found i...
Read Article Now Book Mark ArticleKnowing the kind and amount of carbohydrates in your food will help you plan your meals.
Your provider will explain how to calculate how much insulin you should take to manage your blood sugars after eating.
COUNTING YOUR CARBS
You can use a technique called "carb counting" to track how many carbohydrates you should be eating in your meals and snacks in a day to keep your blood sugars within the target range. You need to match your insulin dose to the total amount of carbs you take in through food or drinks.

Read Article Now Book Mark ArticleIf you take a fixed dose of insulin, you should take in the same amount of carbs at each meal every day.
Tracking carbs at each meal will help you to manage your blood sugar levels. Packaged foods have nutrition facts labels that tell you the type and amount of different nutrients in the food item. Learn how to read food labels to count the carbs that you eat. The carb count for a food includes sugar and starch plus fiber.

Read Article Now Book Mark ArticleCarbs are measured in grams. When you are carb counting, a serving (sometimes also called "a carb") equals an amount of food that contains 15 grams of carbohydrates. Check for the "total carbohydrate" count and the serving size on the nutrition facts label of the food item to decide the amount of food you can eat.
Foods such as fresh fruits and vegetables do not have food labels on them. There are several apps and tools available to help you calculate the amount of carbs in them. Your provider can also help.
When you count carbs in foods that you cook, you will have to measure the portion of food after cooking it. The total amount of carbohydrates you eat in a day is the sum of the carbohydrates in everything you eat.
Manage Your Blood Glucose While Exercising
With type 1 diabetes, you need to learn how to balance diet, insulin intake, and physical activity to keep your blood sugar in the target range. Getting regular exercise is important for your overall health. It can also help you manage diabetes. However, it's not always easy to predict how blood sugar will respond to exercise. Different types of exercise can make blood sugar go up or down. Most of the time, your response to any specific exercise will be the same. Testing your blood sugar before, during, and after a workout session will help you know which activities raise or lower your blood sugar level the most.
Getting regular exercise
Exercise is an important part of managing your diabetes. If you are obese or overweight, exercise can help you manage your weight.
Read Article Now Book Mark ArticleWhen you plan to exercise:
- Talk with your provider or diabetes educator before starting a new exercise program.
- Consider light to moderate exercises such as speed walking, biking, or swimming.
- Strenuous physical activities may lead to hypoglycemia, check your blood glucose often until you know how they affect you.
- Keep a snack or a drink rich in carbs nearby that can raise your blood sugar quickly if it drops down during activity. You may also consider keeping a snack in your car or bedside if your blood sugar drops later in the day.
- Avoid exercise if your blood glucose levels are above 300 mg/dL.
- Have a small carbohydrate rich snack (about 15 grams) before your workout session if your blood glucose levels are less than 100 mg/dl.
- Learn from your provider or diabetes educator how to adjust insulin dose before and after exercise. This may depend on whether you are doing exercise before or after a meal and also on the intensity level and duration of your workout session.
- Do not inject insulin in a part of your body that you are exercising, such as the shoulders or thighs.
- Try to exercise at the same time of day, for the same amount of time, and at the same level.
Exercise can cause your blood sugar to decrease for up to 12 hours after you are done. If exercise frequently causes your blood sugar to be low, talk with your provider or diabetes educator. You may need to lower the dose of your insulin.
It's a good idea to wear a diabetes ID bracelet. In case of an emergency, it will let people know you have diabetes so you can get the right medical attention.
