Case study: Carol is 17 years old and was diagnosed with Type 1 diabetes at the age of 7 years. Carol has had a recent hospital admission for dehydration and high blood glucose. During the admission Carol was found to be 6 weeks pregnant. Prior to the admission she had been experiencing weight loss and changes in mood.
Following Carol’s diagnosis, she would have been made aware of the pathophysiology of type 1 diabetes. Carol would have had explained the role of the immune system in the destruction of beta cells and development of type 1 diabetes. Following Carol’s recent hospital admission, she would have been informed of how the destruction of beta cells affects glucose regulation in the blood which would have brought on her recent admission. This is due to her beta cells being destroyed by the natural immune system, consequently destroying the production of insulin, therefore taking away her energy which we require each day, causing dehydration and high blood glucose.
Type 1 diabetes develops when the beta-cells are killed off by the immune system. This is because an inflammation is caused which the immune system fights off, ultimately destroying all/majority of beta cells. The role of the beta cells is to produce insulin within the pancreas. The beta cells are signalled when to release insulin’s to certain parts of the body. A person with type 1 diabetes is likely to have lost 70-80%1 of their beta-cells mass which is why they must manually inject insulin into themselves to maintain a healthy blood glucose level. When the blood glucose level falls (hypoglycaemia) you begin to lose energy.
The beta cells affect a person’s glucose regulations within the blood. This is because the beta cells are in charge of sending insulin arou...

My patient Hannah is a 10 year old 4th grade student who loves volleyball and was just diagnosed with type 1 diabetes mellitus. I’m going to explain to you what her disorder is, the signs and symptoms, causes of this disorder, body changes, economic impact, and how she will manage this disorder especially at such a young age.
According WebMD 2014. Diabetes mellitus (or diabetes) is a chronic, lifelong condition that affects your body's ability to use the energy found in food. There are three major types of diabetes. Type 1 diabetes mellitus, type 2 diabetes mellitus and gestational diabetes. It is a hormonal disorder of the pancreas either decrease in insulin level also known as hypoinsulinism or increase in insulin level also known as hyperinsulinism. Lowered amounts, insufficient of, or ineffective use of insulin leads to the disorder of diabetes mellitus. It is common chronic disease requiring lifelong behavioral and lifestyle changes. According to Peakman (2012). The development of type 1 diabetes mellitus is a genetic and an autoimmune process that results in destruction of the beta cells of the pancreas, leading to absolute insulin deficiency. There is usually a pre-diabetic phase where autoimmunity has already developed but with no clinically apparent insulin dependency. Insulin autoantibodies can be detected in genetically predisposed individuals as early as 6-12 months of age. In persons genetically susceptible to type 1 diabetes, a triggering event, possibly a viral infection the leads to production of autoantibodies that kill the beta cells and results in decline and a lack of insulin secretion. According to Wherrett. It is caused by impaired insulin secretion and insulin resistance and has a gradual onset. Those with type 2 diabetes may eventually need insulin treatment. Gestational diabetes mellitus is glucose intolerance during pregnancy in a woman not previously diagnosed with diabetes, this may occur if placental hormones counteract insulin, causing insulin intolerance. Complications in diabetes mellitus includes: Hypoglycemia it is ca...
Type 1 Diabetes Mellitus is also referred to as insulin-dependent as the secretion of the hormone insulin by the pancreas is reduced to minor levels due to the destruction of the pancreatic beta cells by immune system of the body. Therefore, Type 1 Diabetes is an autoimmune condition due to the fact that the body is harming the pancreas with antibodies so beta cells cannot make any insulin for bloodstream to take in glucose. The fact that the cells in the body cannot take in glucose means that it builds up in the blood and hyperglycaemia occurs. This abnormally high level of blood glucose is able to harm the nervous system, tiny blood vessels in the kidneys, heart and the eyes. Type 1 Diabetes is fatal when left untreated as it then causes heart disease, kidney disease, damage to the nerves, stroke and
Type 1 Diabetes formerly called juvenile onset diabetes occurs typically before the age of 20, but now at any age anyone can be diagnosed with type 1. Individuals with type 1 diabetes are usually thin, go to the bathroom a lot to urinate, and are always hungry. The cause of Type 1 Diabetes is that the pancreas, which is the organ that secretes insulin, is destroyed by auto antibodies, which is why people with Type 1 Diabetes always need insulin, either to be injected or through an insulin pump. When glucose cannot enter the cells, it builds up in the blood causing the body's cells to starve to death. People with type 1 diabetes mus...
1. Type 1 diabetes is a result from the body’s failure to produce insulin, which requires the individual to inject insulin in other ways (RCT).
The focus for finding an immunological cure for diabetes mellitus type 1 should be directed to prevent maturation or cause inactivation of autoreactive T cells to halt the destruction of insulin-producing beta cells. Inactivation of the autoreactive T cells can be accomplished in two ways. First, antigen presenting cells, such as dendritic cells, that present auto antigens can be modified to prevent maturation or expression of co-stimulatory receptor. Secondly, the T cell can remain in the naïve state or be inactivated after activation by an antigen presenting cell. Diabetes mellitus, commonly known as diabetes, is categorized into type 1, insulin dependent, and type 2, insulin resistant, and the focus will be on the former. Type 1diabetes is a chronic autoimmune disease occurring when insulin-producing beta cells are destroyed by autoreactive CD8 T cells.1 Beta cells are endocrine cells that only secrete insulin and are found in the islets of Langerhans in the pancreas. When the first clinical symptoms of diabetes are apparent in a patient, 80% of the beta cells have already been destroyed.1When large amounts of beta cells are destroyed, it only leaves a fraction of insulin left for the body to utilize, which is often not enough to support function. Type 1 diabetes affects an estimated 30 million people worldwide.1 There is no cure for type 1 diabetes and someone with this disease would need to monitor their blood glucose levels and manually give themselves insulin injections to regulate those levels. However, using insulin injections is not a cure.
Diabetes is a metabolic disease where the body is unable to produce any- or enough- insulin which causes high glucose levels in return. There are 3 different types of diabetes that people are most familiar with. Type 1 diabetes, which is an autoimmune disease where that person would need insulin from the second they’re diagnosed. Type 2 diabetes, which may take months or even years for a person to require insulin. With type 2 diabetes, the affected person is usually older and overweight. The third type that people are most familiar with is Gestational diabetes. GD occurs during pregnancy. Around 28 weeks gestation, the pregnant woman is instructed to go for a one hour glucose test to check for diabetes. Usually after the pregnancy, the diabetes goes away- although there are some cases where it doesn’t.
Type 1 diabetes has a genetic onset that often occurs in adolescence (Porth, 2005). It is an autoimmune disease in which the insulin-producing beta cells within the liver are destroyed (Dorman, 1993). This causes a deficiency in insulin secretion, which ultimately leads to high blood glucose levels, also referred to as hyperglycemia (Guthrie & Guthrie, 2004). The mechanism for insulin deficiency leading to hyperglycemia is described in more detail in the following section and in Figure 1.

Diabetes is a disease that affects the body’s ability to produce or respond to insulin, a hormone that allows blood glucose (blood sugar) to enter the cells of the body and be used for energy. Diabetes falls into two main categories: type 1, or juvenile diabetes, which usually occurs during childhood or adolescence, and type 2, or adult-onset diabetes, the most common form of the disease, usually occurring after age 40. Type 1 results from the body’s immune system attacking the insulin-producing cells in the pancreas. The onset of juvenile diabetes is much higher in the winter than in the summer. This association has been repeatedly confirmed in diabetes research. Type 2 is characterized by “insulin resistance,” or an inability of the cells to use insulin, sometimes accompanied by a deficiency in insulin production. There is also sometimes a third type of diabetes considered. It is gestational diabetes, which occurs when the body is not able to properly use insulin during pregnancy. Type 2 diabetes encompasses nine out of 10 diabetic cases. Diabetes is the fifth-deadliest disease in the United States, and it has no cure. The total annual economic cost of diabetes in 2002 was estimated to be $132 billion, or one out of every 10 health care dollars spent in the United States. Diabetes risk factors can fall into three major categories: family history, obesity, and impaired glucose tolerance. Minority groups and elderly are at the greatest risk of developing diabetes.
Even though it has long been known that women with preexisting type 1 and type 2 diabetes are at increased risk for adverse maternal and fetal outcomes, the relationship of GDM to various perinatal risks has been less clear. O'Sullivan and Mahan3 developed, Glucose tolerance test criteria for the diagnosis of GDM, nearly 50 years ago. It has been known that, if optimal care is not provided, women with GDM and elevated fast¬ing glucose levels appear to be at risk for fetal overgrowth and perinatal morbidity.4
Type 1 diabetes, is an incurable but treatable disease which can occur at any age but is mostly found in children due to the high levels of glucose in the blood (Eckman 2011). Juvenile diabetes affects about 1 in every 400-600 children and more than 13,000 are diagnosed yearly (Couch 2008). Type 1 Diabetes means your blood glucose, or blood sugar, is too high. With Type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone, which helps glucose gets into your cells to provide energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, gums and teeth (American Diabetes Association). Previous research has suggested proper insulin management, a balanced diet and exercise will help maintain glycemic control and lessen the chance of complications (Couch 2008).
Gestational diabetes mellitus (GDM) is an intolerance of glucose documented for the first time during pregnancy. It is usually a short-term type of diabetes and the most common health problem with pregnant women. GBM is caused by the way the hormones in pregnancy affect the mother. GDM accounts for 5-7% of all pregnancies (American Diabetes Association, 2010). During pregnancy the placenta develops and becomes the main bond between the mother and the baby. It is used to make sure the baby has and gets enough nutrients. The placenta makes several hormones which make it hard for insulin to control blood glucose and block the action of the mother’s insulin in her body (American Diabetes Association, 2010). Hormonal changes during the pregnancy causes the body to be less sensitive to insulin. Insulin has the job of opening up the cells so that the glucose can get inside regulating the amount of glucose in the blood while glucose is the amount of sugar in the blood stream. In pregnancy, the body needs to make three times more insulin for control of the blood sugar. GDM is usually found within the second trimester of a pregnancy and increases until the end of the pregnancy. Usually within a few hours of delivery the condition resolves itself (American Diabetes Association, 2010).
In conclusion, women with a history of gestational diabetes have an increased risk of developing type 2 diabetes in the future. By following health interventions they are able to decrease the chance and can avoid the development of diabetes. Abiding by these healthy lifestyle changes increases quality of life of both mom and infant.
