Type diabetes causes -

Type 2 diabetes usually begins with insulin resistance , a condition in which muscle, liver , and fat cells do not use insulin well. As a result, your body needs more insulin to help glucose enter cells. At first, the pancreas makes more insulin to keep up with the added demand.

As in type 1 diabetes, certain genes may make you more likely to develop type 2 diabetes. Scientists believe gestational diabetes , a type of diabetes that develops during pregnancy, is caused by the hormonal changes of pregnancy along with genetic and lifestyle factors.

Hormones produced by the placenta contribute to insulin resistance, which occurs in all women during late pregnancy. Most pregnant women can produce enough insulin to overcome insulin resistance, but some cannot. As with type 2 diabetes, extra weight is linked to gestational diabetes. Women who are overweight or have obesity may already have insulin resistance when they become pregnant.

Gaining too much weight during pregnancy may also be a factor. Having a family history of diabetes makes it more likely that a woman will develop gestational diabetes, which suggests that genes play a role. Genetic mutations , other diseases, damage to the pancreas, and certain medicines may also cause diabetes.

Some hormonal diseases cause the body to produce too much of certain hormones, which sometimes cause insulin resistance and diabetes. Pancreatitis , pancreatic cancer, and trauma can all harm the beta cells or make them less able to produce insulin, resulting in diabetes.

If the damaged pancreas is removed, diabetes will occur due to the loss of the beta cells. However, statins help protect you from heart disease and stroke. For this reason, the strong benefits of taking statins outweigh the small chance that you could develop diabetes.

If you take any of these medicines and are concerned about their side effects, talk with your doctor. This content is provided as a service of the National Institute of Diabetes and Digestive and Kidney Diseases NIDDK , part of the National Institutes of Health.

People who are overweight when they get pregnant or who gain too much weight during pregnancy are more likely to get gestational diabetes. Get more information on the causes of diabetes.

Adults who have African American, Hispanic or Latino American, or Asian American ancestry are more likely to be diagnosed with type 2 diabetes than white adults, according to research. Your family history, environment, and preexisting medical conditions can all affect your odds of developing diabetes.

High blood sugar damages organs and tissues throughout your body. The higher your blood sugar is and the longer you live with it, the greater your risk for complications. Unmanaged gestational diabetes can lead to problems that affect both the mother and baby.

Complications affecting the baby can include:. A pregnant person with gestational diabetes can develop complications such as high blood pressure preeclampsia or type 2 diabetes. You may also require cesarean delivery , commonly referred to as a C-section.

Diabetes can lead to serious medical complications, but you can manage the condition with medications and lifestyle changes. Avoid the most common diabetes complications with these helpful tips.

Doctors treat diabetes with a few different medications. Some are taken by mouth, while others are available as injections. Insulin is the main treatment for type 1 and 1. Various types of insulin are commonly used by people with type 1 and 1.

They differ in how quickly they start to work and how long their effects last:. Diet and exercise can help some people manage type 2 diabetes. You may need to take more than one of these medications.

Some people with type 2 diabetes also take insulin. Insulin is safe for the developing baby. The treatment regimen your doctor recommends will depend on the type of diabetes you have and its cause.

Check out this list of the various medications that are available to treat diabetes. Healthy eating is a central part of managing diabetes.

In some cases, changing your diet may be enough to manage the disease. Your blood sugar level rises or falls based on the types of foods you eat. Starchy or sugary foods make blood sugar levels rise rapidly. Protein and fat cause more gradual increases. Your medical team may recommend that you limit the amount of carbohydrates you eat each day.

Counting carbs helps to balance the carb intake with the insulin doses. Check out this guide to starting a type 1 diabetes diet. Eating the right types of foods can both manage your blood sugar and help you lose any excess weight.

Carb counting is an important part of eating for type 2 diabetes. A dietitian can help you figure out how many grams of carbohydrates to eat at each meal. In order to keep your blood sugar levels steady, try to eat small meals throughout the day. Emphasize healthy foods such as:.

Discover the foods you should avoid if you have diabetes. Eating a well-balanced diet is important for both you and your baby during these 9 months. Making the right food choices can also help you avoid diabetes medications.

Watch your portion sizes, and limit sugary or salty foods. Although you need some sugar to feed your growing baby, you should avoid eating too much. Work with a registered dietitian if you have access to one.

They can help you design an individualized diabetes meal plan. Getting the right balance of protein, fat, and carbs can help you manage your blood sugar.

Along with diet and treatment, exercise plays an essential role in diabetes management. This is true for all types of diabetes. Staying active helps your cells react to insulin more effectively and lower your blood sugar levels.

Exercising regularly can also help you:. If you have type 1 or type 2 diabetes, general guidance is to aim for at least minutes of moderate-intensity exercise each week.

There are currently no separate exercise guidelines for people who have gestational diabetes. Diabetes-friendly exercises include:. Talk with your doctor about safe ways to incorporate activity into your diabetes management plan.

You may need to follow special precautions, like checking your blood sugar before and after working out and making sure to stay hydrated.

Consider working with a personal trainer or exercise physiologist who has experience working with people who have diabetes. They can help you develop a personalized workout plan tailored to your needs. Anyone who has symptoms of diabetes or is at risk for the condition should be tested.

People are routinely tested for gestational diabetes during their second trimester or third trimester of pregnancy. Doctors use these blood tests to diagnose prediabetes and diabetes:. To diagnose gestational diabetes , your doctor will test your blood sugar levels between the 24th week and 28th week of pregnancy.

There are two types of tests:. The earlier you are diagnosed with diabetes, the sooner you can start treatment. Find out whether you should get tested, and get more information on tests your doctor might perform.

Type 1 and type 1. Yet many other diabetes risk factors are manageable. Most diabetes prevention strategies involve making simple adjustments to your diet and fitness routine. Discover more strategies that may help you avoid this chronic health condition.

Hormones produced by the placenta can make your body more resistant to the effects of insulin. People can have diabetes before they conceive and carry it with them into pregnancy. This is called pre-gestational diabetes. Diabetes during pregnancy can lead to complications for your newborn, such as jaundice or breathing problems.

Gestational diabetes should go away after you deliver, but it does significantly increase your risk of getting diabetes later.

About half of people with gestational diabetes will go on to develop type 2 diabetes. Children can get both type 1 and type 2 diabetes. Managing blood sugar is especially important in young people because diabetes can damage important organs such as the heart and kidneys.

The autoimmune form of diabetes often starts in childhood. One of the main symptoms is increased urination. Extreme thirst, fatigue, and hunger are also signs of the condition. The condition can cause high blood sugar, dehydration , and diabetic ketoacidosis DKA , which can be medical emergencies.

Type 1 diabetes used to be called juvenile diabetes because type 2 was so rare in children. Now that more children have overweight or obesity , type 2 diabetes is becoming more common in this age group.

Untreated type 2 diabetes can cause lifelong complications, including heart disease, kidney disease, and blindness. Healthy eating and exercise can help your child manage their blood sugar and prevent these problems. Type 2 diabetes is more prevalent than ever in young people.

Some types of diabetes — like types 1 and 1. Others — like type 2 — can be prevented by making better food choices, increasing activity, and losing weight. Discuss potential diabetes risks with your doctor. We encourage our readers to share their unique experiences to create a helpful and informative community here on Healthline.

: Type diabetes causes

What is Diabetes?	Type 2 diabetes, the most common type of diabetes, is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes mainly from the food you eat. Insulin , a hormone made by the pancreas , helps glucose get into your cells to be used for energy. Too much glucose then stays in your blood, and not enough reaches your cells. You can develop type 2 diabetes at any age, even during childhood. However, type 2 diabetes occurs most often in middle-aged and older people. You are more likely to develop type 2 diabetes if you are age 45 or older, have a family history of diabetes, or are overweight or have obesity. Physical inactivity and certain health problems such as high blood pressure affect your chances of developing type 2 diabetes. You are also more likely to develop type 2 diabetes if you have prediabetes or had gestational diabetes when you were pregnant. Learn more about risk factors for type 2 diabetes. Symptoms of type 2 diabetes often develop slowly—over the course of several years—and can be so mild that you might not even notice them. Many people have no symptoms. Some people do not find out they have the disease until they have diabetes-related health problems, such as blurred vision or heart disease. Learn more about the causes of type 2 diabetes. Your health care professional can diagnose type 2 diabetes based on blood tests. Learn more about blood tests for diabetes and what the results mean. Managing your blood glucose, blood pressure , and cholesterol , and quitting smoking if you smoke, are important ways to manage your type 2 diabetes. Lifestyle changes that include planning healthy meals, limiting calories if you are overweight, and being physically active are also part of managing your diabetes. So is taking any prescribed medicines. Work with your health care team to create a diabetes care plan that works for you. When your blood sugar goes up, it signals your pancreas to release insulin. Over time, that can cause serious health problems, such as heart disease , vision loss , and kidney disease. Other things you can do to help:. There are three main types of diabetes: type 1 , type 2 , and gestational diabetes diabetes while pregnant. Type 1 diabetes is thought to be caused by an autoimmune reaction the body attacks itself by mistake. This reaction stops your body from making insulin. Type 1 diabetes can be diagnosed at any age, and symptoms often develop quickly. Currently, no one knows how to prevent type 1 diabetes. It develops over many years and is usually diagnosed in adults but more and more in children, teens, and young adults. Type 2 diabetes can be prevented or delayed with healthy lifestyle changes, such as:. Gestational diabetes develops in pregnant women who have never had diabetes. If you have gestational diabetes, your baby could be at higher risk for health problems. Gestational diabetes usually goes away after your baby is born. However, it increases your risk for type 2 diabetes later in life. Your baby is more likely to have obesity as a child or teen and develop type 2 diabetes later in life. In the United States, about 98 million adults—more than 1 in 3—have prediabetes. Side effects include a higher risk of urinary and genital infections and ketoacidosis. GLP-1 receptor agonists work by increasing the amount of insulin the body produces and decreasing the amount of glucose that enters the bloodstream. It is an injectable medication. People may use it with metformin or alone. Side effects include gastrointestinal problems, such as nausea and loss of appetite. Learn more about other medications and treatments for managing diabetes. Self-monitoring blood sugar levels is vital for effectively managing diabetes. It helps regulate meal schedules, physical activity, and when to take medication, including insulin. While self-monitoring blood glucose machines vary, they generally include a meter and test strip for generating readings. Self-monitoring also involves using a lancing device to prick the skin to obtain a small quantity of blood. People should refer to the specific instructions of a meter in every case, as machines will differ. However, the following precautions and steps generally apply to many devices on the market:. People checking their blood sugar levels with a blood glucose meter also use a device called a lancet to prick their finger. While the idea of drawing blood might cause distress for some people, lancing the skin to obtain a blood sample should be a gentle, simple procedure. Many meters require only a teardrop-sized sample of blood. A person may also find the following tips useful:. While remembering to self-monitor involves people making lifestyle adjustments, it does not need to be an uncomfortable process. Diabetes is a serious, chronic condition. According to the American Diabetes Association , diabetes was the eighth leading cause of death in the United States in While diabetes is manageable, its complications can severely affect daily living. Some complications can be fatal if not treated immediately. Complications of diabetes include :. Regularly monitoring blood sugar levels and moderating glucose intake can help people prevent the more damaging complications of diabetes. For those living with type 1 diabetes, administering insulin is the main way to help them manage the condition. A person can speak with a doctor to discuss the best treatment options for type 2 diabetes. However, common treatment options include the following types of medication:. The most common type of medication for type 2 diabetes is metformin. Metformin decreases the amount of glucose the liver produces, which lowers blood glucose levels. To help manage blood sugar levels, a person can drink water, including flavored, sugar-free water, and herbal teas. Learn more about the best and worst drinks for people with diabetes. This is because the body can make insulin but does not respond well to it. In type 2 diabetes, insulin can help the body use glucose for energy. Diabetes is a life changing condition that requires careful blood sugar management and healthy lifestyle strategies for a person to manage it safely. There are several types of diabetes. Type 1 occurs when the body does not produce insulin. Depending on the type of diabetes, people may need to administer insulin and take other medications to manage their condition and improve glucose absorption. If a person is living with prediabetes, they can reduce the risk of developing type 2 diabetes through regular exercise and a balanced diet. The complications of diabetes can be severe, including kidney failure and stroke, so managing the condition is vital. Read this article in Spanish.

Overweight, obesity, and physical inactivity You are more likely to develop type 2 diabetes if you are not physically active and are overweight or have obesity. Insulin resistance Type 2 diabetes usually begins with insulin resistance , a condition in which muscle, liver , and fat cells do not use insulin well.

Genes and family history As in type 1 diabetes, certain genes may make you more likely to develop type 2 diabetes. Insulin resistance Hormones produced by the placenta contribute to insulin resistance, which occurs in all women during late pregnancy.

Hormonal changes, extra weight, and family history can contribute to gestational diabetes. Genes and family history Having a family history of diabetes makes it more likely that a woman will develop gestational diabetes, which suggests that genes play a role.

Genetic mutations Monogenic diabetes is caused by mutations, or changes, in a single gene. These changes are usually passed through families, but sometimes the gene mutation happens on its own. Most of these gene mutations cause diabetes by making the pancreas less able to make insulin.

The most common types of monogenic diabetes are neonatal diabetes and maturity-onset diabetes of the young MODY. Neonatal diabetes occurs in the first 6 months of life. Doctors usually diagnose MODY during adolescence or early adulthood, but sometimes the disease is not diagnosed until later in life.

However, you do have a higher risk of developing type 2 diabetes later in life. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.
