What is the cause of diabetes? This varies from one type of the disease to another. Questions still abound as to exactly why some people get diabetes and others don't. While it may be some time before all the questions about it are answered, some things are generally considered to be true. Risk factors play a large role. People who eat properly and get regular exercise are generally more healthy and tend to develop fewer risk factors like obesity and high blood pressure. Genetic factors however are beyond our control.
The cause of diabetes type 1: The body stops making insulin or or doesn't make enough insulin to regulate the blood sugar level. This type makes up approximately 10% of all cases diagnosed in the U.S. Previously called juvenile-onset diabetes or insulin-dependent diabetes mellitus, type 1 diabetes is usually seen in children or teens. It can also occur in older people due to removal of or damage to the pancreas. Daily insulin is necessary for keeping a type 1 patient alive.
Diabetes type 2 is the most commonly diagnosed form of the disease. The cause of diabetes type 2 is a metabolic disorder in which the body has difficulty utilizing its own insulin to manage the blood sugar. At the onset of the disease, beta cells are frequently producing as much or more insulin as would be required by a different person of equal weight. But resistance to insulin occurs due to changes in liver, fat and muscle cells. Insulin injections, exercise and diet modification are typical treatments.
Gestational diabetes is caused by pregnancy. Gestational diabetes is a type of diabetes that can occur while a woman is pregnant. Three to five percent of women who are pregnant develop the disease. Like the other types of diabetes, gestational diabetes makes it difficult to manage the blood sugar levels.
Blood glucose levels that are higher than normal but not yet high enough to be diagnosed as diabetes is the cause of pre-diabetes. More than fifty million people in the U.S. have pre-diabetes. Studies have shown that some permanent damage to some parts of the body, typically the heart and circulatory system, may occur during pre-diabetes.
The cause of diabetes varies from one form of the disease to the next. Of all diseases diabetes is the sixth leading killer in the U.S. Talk to your doctor about any symptoms that you may have so that he or she can make a diagnosis. Many symptoms related to diabetes are symptoms of other serious diseases as well so see your doctor at least once a year.
Diabetes is an affection which occurs is the body has a problem in making or using the insulin. The role of the insulin is to take the glucose from the blood and move it to cells which use it for producing energy. If the insulin is not enough or it can not be used by the body then the glucose will remain in the blood and the symptoms of diabetes will appear.
In some cases the body produces enough insulin but this can not enter the cells and help the process of producing energy. This way the glucose will remain in the blood, causing hyperglycemia and the level of the insulin will be high too as it is not used by the cells. Most of these patients which are known to have insulin resistance are also obese. The fat cells stop the insulin from being used by the other cells and this also counts in the malfunctioning of the energy process. This kind of diabetes is known as diabetes type 2.
There are cases when diabetes type2 occurs in slim parsons and this mostly happens in elder people. Genetics and family history also have an important role in determining whether diabetes type 2 will install or not. Also, having a sedentary lifestyle, eating junk food will only increase the risk of developing this affection.
Some other risk factors are: the age over 45, high blood pressure, HDL less than 35 mg/dl, triglycerides more than 250 mg/dl and a previous history of personal impaired glucose tolerance.
Most of the diabetes type 2 cases do not present any symptoms at all. In some cases increased thirst, appetite and urination might occur along with blurred vision, fatigue, infections, and erectile dysfunctions.
In order to diagnose diabetes type 2 the doctor will perform some tests: the level of fasting glucose in blood will be measured and if it is higher than 126 mg/dl on 2 occasions than diabetes might have installed. The random glucose blood level will also be measured and it should be less than 200 mg/dl in order for the doctor to be sure diabetes in not present. Also, the symptoms of increased thirst, urination and fatigue should not be present in order for the patient not to be suspected of having diabetes. At last, the oral glucose tolerance test will be performed and if the level of glucose is higher than 200 mg/dl after 2 hours diabetes is diagnosed.
