The exact cause of most types of diabetes is unknown. In all cases, sugar builds up in the bloodstream. This is because the pancreas doesn't produce enough insulin. Both type 1 and type 2 diabetes may be caused by a combination of genetic or environmental factors.
Type 1 diabetes occurs when your immune system, the body's system for fighting infection, attacks and destroys the insulin-producing beta cells of the pancreas. Scientists think type 1 diabetes is caused by genes and environmental factors, such as viruses, that might trigger the disease.
Type 1 diabetes can develop quickly over weeks or even days. Weight loss is common in people with type 1 diabetes when it first develops and before it's treated, but it's less common in people with type 2 diabetes.
Take time to do things you enjoy.
Remember that it's important to pay attention to your feelings. If you notice that you're feeling frustrated, tired, and unable to make decisions about your diabetes care, take action. Tell your family, friends, and health care providers. They can help you get the support you need.
Even Really Healthy People Are Prone to Diabetes: Here's What You Should Know. We often assume that just because a person is skinny, they're in perfect health. However, even healthy people can develop insulin resistance, a condition that leads to high blood sugar or diabetes.
Stress alone doesn't cause diabetes. But there is some evidence that there may be a link between stress and the risk of type 2 diabetes. Our researchers think that high levels of stress hormones might stop insulin-producing cells in the pancreas from working properly and reduce the amount of insulin they make.
However, the most common symptoms experienced by many people with diabetes are increased thirst, going for a wee a lot, feeling tired and losing weight. To find out more about common diabetes symptoms and what causes them, watch our video.
A fasting blood sugar level of 99 mg/dL or lower is normal, 100 to 125 mg/dL indicates you have prediabetes, and 126 mg/dL or higher indicates you have diabetes.
If you are struggling to get up in the morning; feeling a total lack of energy or 'fogginess' or not able to perform the tasks you normally do as simply too exhausted it may be that you actually are suffering from fatigue... and it could be a side effect of your diabetes.
Type 2 diabetes symptoms often take several years to develop. Some people don't notice any symptoms at all. Type 2 diabetes usually starts when you're an adult, though more and more children and teens are developing it. Because symptoms are hard to spot, it's important to know the risk factors for type 2 diabetes.
increased thirst and a dry mouth. needing to pee frequently. tiredness. blurred vision.
If you have been diagnosed with prediabetes — high blood sugar that doesn't reach the threshold of a diabetes diagnosis — lifestyle changes can prevent or delay the onset of disease.
A diet high in fat, calories, and cholesterol increases your risk of diabetes. A poor diet can lead to obesity (another risk factor for diabetes) and other health problems. A healthy diet is high in fiber and low in fat, cholesterol, salt, and sugar.
These signs and symptoms aren't always as obvious, however, and it's often diagnosed during a routine check-up. This is because they are often mild and develop gradually over a number of years. This means you may have type 2 diabetes for many years without realising it.
Diabetes may start as early as 10 years before development of PDM, which means >20 years before diagnosis of diabetes in the majority of patients.
Type 2 diabetes most often develops in people over age 45, but more and more children, teens, and young adults are also developing it.
Average life expectancy in 2015 in the non-diabetic population is around 74.8 years with longer life expectancy for the female than male population (78 years vs 71) (Table 2). Patients with Type 1 DM and with Type 2 DM are expected to have an average life of 70.96 and 75.19 years at the end of observed period.
