This happens while there is plenty of glucose in the bloodstream, but not enough insulin to help convert glucose for use in the cells. The body recognizes this and starts breaking down muscle and fat for energy. This breakdown produces ketones also called fatty acids , which cause an imbalance in our electrolyte system leading to the ketoacidosis a metabolic acidosis. The sugar that cannot be used because of the lack of insulin stays in the bloodstream rather than going into the cell and provide energy.

DKA is characterized by the presence of hyperglycemia, ketosis, ketonuria, and metabolic acidosis.
Cerebral edema is a rare but rather a serious complication of DKA. His symptoms were deteriorating with a change in sensorial and cognitive functions at the time of presentation. Diabetic ketoacidosis DKA is a potentially life-threatening complication of diabetes mellitus. Description An in-depth report on the causes, diagnosis, treatment, and prevention of type 2 diabetes. About 79 million Americans aged 20 years and older have pre-diabetes, a condition that increases the risk for developing diabetes.
Diabetes and Cancer Type 2 diabetes increases the risk for certain types of cancer, according to a consensus report from the American Diabetes Association and the American Cancer Society. Diabetes doubles the risk for developing liver, pancreatic, or endometrial cancer. Certain medications used for treating type 2 diabetes may possibly increase the risk for some types of cancers. Screening for Gestational Diabetes Mellitus The American Diabetes Association recommends that pregnant women without known risk factors for diabetes get screened for gestational diabetes at 24 - 28 weeks of pregnancy.
Pregnant women with risk factors for diabetes should be screened for type 2 diabetes at the first prenatal visit. Aspirin for Heart Disease Prevention The American Diabetes Association now recommends daily low-dose 75 - mg aspirin for men older than age 50 and women older than age 60 who have diabetes and at least one additional heart disease risk factor such as smoking, high blood pressure, high cholesterol, family history, or albuminuria.
Jump to Section 1. Insulin deficiency, increased insulin counter-regulatory hormones cortisol, glucagon, growth hormone, and catecholamines and peripheral insulin resistance lead to hyperglycemia, dehydration, ketosis, and electrolyte imbalance, which underlie the pathophysiology of DKA [2].
While DKA is a commonly recognized vulnerability in autoimmune diabetes, stressful conditions such as trauma, surgery, or infection also increase DKA risk in patients with type 2 diabetes mellitus [4]. Diabetes is a chronic state of hyperglycaemia caused by a lack of or diminished effectiveness of endogenous insulin.
Over time it can cause specific tissue damage, particularly to the retina, kidney, nerves and arteries. However, this is not necessarily true in descriptive terms, as not all type 1 sufferers require insulin, and not all type 2 sufferers do not require insulin many in the later stages of the disease do.

Your urine tests show high levels of ketones and your blood glucose level is high. Your urine tests show high levels of ketones and you have vomited more than twice in four hours.
What causes DKA? Here are three basic reasons for moderate or large amounts of ketones: Not enough insulin Maybe you did not inject enough insulin.
Or your body could need more insulin than usual because of illness. Not enough food When you're sick, you often don't feel like eating, sometimes resulting in high ketone levels.
High levels may also occur when you miss a meal. Insulin reaction low blood glucose If testing shows high ketone levels in the morning, you may have had an insulin reaction while asleep.

While some investigators assume that long standing type 2 diabetes predisposes to pancreatic cancer 7 , 8 , a recent study showed that in many pancreatic cancer patients, glucose intolerance and new onset diabetes occurs at the initial presentation.
The evidence for diabetes as a cause of pancreatic cancer is based on limited animal studies. It has been postulated that prolonged exposure to hyperinsulinemia stimulates the growth of pancreatic cancers via the insulin receptors found on the pancreatic cells.
In humans, the link between diabetes and pancreatic cancer is based primarily on a temporal relationship. These are intriguing, but inconclusive linkages, and do not apply to our patient who had diabetes for 15 years prior to presentation with pancreatic cancer. Thus despite the numerous studies performed to elucidate the relationship between these two diseases, there is no conclusive evidence regarding cause and effect. Additional efforts to examine the relationship between diabetes and pancreatic cancer have looked at glucose metabolism and insulin response.
Peripheral insulin resistance and concurrent impairment of beta cell response to glucose are suggested as primary mechanisms for diabetes in pancreatic cancer. Reduced glycogen synthesis and storage in skeletal muscle, contributing to hyperglycemia has also been observed. After tumor resection, there was improvement of insulin sensitivity and diabetes status. The simple loss of normal functioning pancreatic mass has always been a consideration in the genesis of diabetes.
DKA can result from a significant loss of beta cell and pancreatic polypeptide PP -secreting cells. PP cells are primarily located in the ventral pancreatic head and uncinate process.
These cells inhibit exocrine pancreatic secretion and gallbladder contraction and act as hormonal mediators of glucose metabolism. Deficiency of PP cells is associated with hepatic resistance to insulin and inappropriate hepatic glucose production, contributing to persistent hyperglycemia. Two other postulated mechanisms, islet cell dysfunction 21 , 22 and diabetes as a paraneoplastic phenomenon 23 — 26 , have been offered to explain the temporal link between diabetes and pancreatic cancer.
Despite the preservation of endocrine pancreatic function after a large loss of pancreatic islets, there is minimal increase in C-peptide concentration after intravenous glucagon stimulation in pancreatic adenocarcinoma patients. Additional evidence for dysfunctional islet cells includes a delay in proinsulin maturation 27 and increased amylin islet amyloid polypeptide secretion in pancreatic cancer patients. The suggestion that diabetes could be a paraneoplastic phenomenon comes from animal models in which pancreatic cancer cells secreted non-immunological mediators that interfered with glucose metabolism, amylin secretion, and peripheral action of insulin.
In our patient, her longstanding diabetes prior to the development of DKA with recently poorly controlled diabetes mellitus may be consistent with the undiagnosed pancreatic cancer. Despite the large tumor mass upon presentation, the change in her diabetic pattern and pancreatic failure are likely secondary to intrinsic mechanisms, rather than the local effect of the tumor.
Transient insulinopenia, peripheral insulin resistance and beta cell dysfunction secondary to the presence of pancreatic cancer may have contributed to the persistent hyperglycemic state. The associated stress of poor nutrition, profound weight loss and large tumor burden may have predisposed her metabolic decompensation and led to DKA. DKA is no longer exclusively associated with type 1 diabetics. While the majority of patients presenting with DKA are type 1 diabetics, a minority will be patients with type 2 diabetes.
In many of these patients, an obvious precipitant will be found. Considering pancreatic cancer in both newly diagnosed and known type 2 diabetics presenting with DKA without obvious precipitant s may be appropriate.
This case also raises the possibility of pancreatic cancer related pancreatic failure, paraneoplastic syndrome, and cachexia with starvation ketosis, as contributory factors in the development of DKA in this setting. Pancreatic cancer should be considered as a possible precipitant of DKA if common factors are not identified.
The stressors precipitating DKA in type 2 diabetics cause transient insulinopenia rather definitive insulin deficiency. Evidence is inconclusive regarding the cause and effect between diabetes mellitus and pancreatic cancer.
