Because the symptoms of type 1 diabetes often develop rapidly and can be dramatic, it frequently can be quickly diagnosed. Type 1 diabetes can be diagnosed during a routine office visit using a combination of history and physical exam and simple blood tests, including a fasting blood glucose test or a random blood glucose test. High levels of glucose can sometimes be seen in an urinanalysis performed on urine. The newest form of testing for diabetes is the glycated hemoglobin (A1C) test, which measures the average overall blood sugar for the past several months....more about Type 1 diabetes »

Metabolic syndrome often undiagnosed: Metabolic syndrome, also known as Syndrome X, is an often overlooked medical condition that causes a cluster of chronic symptoms. There are often four symptoms and conditions combined: obesity, hypertension (high blood pressure), high cholesterol, and diabetes (Type 2 diabetes) or in come cases pre-diabetes initially. See the introduction to metabolic syndrome.
Heart attacks can be undiagnosed: Although the most severe symptoms of heart attack are hard to miss, there are varying degrees of severity. It is altogether too common for people to die from undiagnosed heart attack, or from delaying too long to call for emergency help. The prognosis for treatment is far better for patients treated in the early stages of a heart attack. The most common misdiagnoses include heartburn, or other less severe causes of chest pain. See the introduction to heart attack and the symptoms of heart attack.
Heart attacks can be overdiagnosed: Although many people die from heart attacks, there are also many cases where people fear that they have a heart attack, but actually have something milder. Some of the conditions which may be causes of chest pain, causing fear of a heart attack, including an anxiety attack, heartburn, and so on. See the causes of chest pain and the symptoms of heart attack.
Rare undiagnosed iron disorder causes various severe conditions: The rare "iron overload" disorder, hemochromatosis, can cause a variety of symptoms and result in various severe conditions that mimic several of the big name medical conditions. However, since it is quite rare (about 1 in 200 to 1 in 300), it may go undiagnosed, and indeed doctors may not even test for it. It can damage the pancreas, causing pancreatitis, leading to diabetes-like symptoms. It can damage the liver, leading to liver symptoms such as jaundice. Hemochromoatis can also damage the joints, giving the appearance of arthritis. The heart is another organ that excess iron can damage. Fortunately, this condition has a relatively simple treatment, and these complications can often be reversed by treatment of the iron overload causing them. See introduction to hemochromatosis.
Cluster of diseases with difficult diagnosis issues: There is a well-known list of medical conditions that are all somewhat difficult to diagnose, and all can present in a variety of different severities. Diseases in this group include multiple sclerosis, lupus, Lyme disease, fibromyalgia, thyroid disorders (hypothyroidism or hyperthyroidism), chronic fatigue syndrome, diabetes - all of these can have vague symptoms in their early presentations. Also, depression can have some symptoms similar to these conditions, and also the reverse, that many of these conditions can mimic depression and be misdiagnosed as depression.
Alzheimer's disease over-diagnosed: The well-known disease of Alzheimer's disease is often over-diagnosed. Patients tend to assume that any memory loss or forgetulness symptom might be Alzheimer's, whereas there are many other less severe possibilities. Some level of memory decline is normal with aging, and even a slight loss of acuity may be noticed in the 30's and 40's. Other conditions can also lead a person to show greater forgetfulness. For example, depression and depressive disorders can cause a person to have reduced concentration and thereby poorer memory retention.
Dementia may be a drug interaction: A common scenario in aged care is for a patient to show mental decline to dementia. Whereas this can, of course, occur due to various medical conditions, such as a stroke or Alzheimer's disease, it can also occur from a side effect or interaction between multiple drugs that the elderly patient may be taking. There are also various other possible causes of dementia.
Rare type of breast cancer without a lump: There is a less common form of breast cancer called inflammatory breast cancer. Its symptoms can be an inflammation of the breast tissue, such as with a breast rash with redness and warmth, but not necessarily a physical breast lump. This type of breast cancer should be considered as an uncommon possibility for certain types of breast symptoms.
Tremor need not be Parkinson's disease: There is the tendency to believe that any tremor symptom, or shakiness, means Parkinson's disease. The reality is that there are various possibilities, such as benign essential tremor, which is mostly harmless. see the various causes of tremor and misdiagnosis of Parkinson's disease.
Poorly healing leg rashes a classic sign of chronic disease: Recurring leg rashes, or poorly healing leg rashes, are a classic sign of undiagnosed diabetes, particularly of Type 2 diabetes, but also Type 1 diabetes. They can also occur with poor diabetic control. However, there are many other possible causes of leg rashes. See causes of leg rash or misdiagnosis of diabetes.
Leg cramps at night a classic sign: The symptom of having leg muscle cramps, particularly at night, is a classic sign of undiagnosed diabetes. However, there are also various other causes. See causes of leg cramps or misdiagnosis of diabetes.
Rare diseases misdiagnosed as Parkinson's disease: A rare genetic disorder is often misdiagnosed as Parkinson's disease for men in their 50's. The disease Fragile X disorder can show only mild symptoms in the early years, and Parkinsons-like symptoms around age 50. See misdiagnosis of Parkinson's disease.
Over-diagnosis of pulmonary hypertension in obese patients: A diagnosis of pulmonary hypertension, particularly pulmonary arterial hypertension, is often a misdiagnosis in obese patients. Exertional dyspnea leads to a diagnostic reading of high right ventricular systolic pressure, which seems to indicate pulmonary hypertension, but is ultimately found to be an incorrect diagnosis. See misdiagnosis of pulmonary hypertension.
Obesity-related conditions undiagnosed in children: A variety of conditions are associated with obesity (see obesity), but these tend to be undiagnosed more often in child patients than in adults. Some of the overlooked conditions may include hypertension, diabetes, acanthosis nigricans, etc. See misdiagnosis of obesity or introduction to obesity.
Misdiagnosed weight-related causes of infertility: A woman's weight status can affect her level of fertility. Although obesity or overweight can in themselves reduce fertility, there are other weight-related or associated medical conditions that further reduce fertility. Some of these hidden causes include COPD, diabetes, thyroid disorders (overactive thyroid or underactive thyroid) and metabolic syndrome. See also other causes of infertility.

When checking for a misdiagnosis of Type 1 diabetes or confirming a diagnosis of Type 1 diabetes, it is useful to consider what other medical conditions might be possible misdiagnoses or other alternative conditions relevant to diagnosis. These alternate diagnoses of Type 1 diabetes may already have been considered by your doctor or may need to be considered as possible alternative diagnoses or candidates for misdiagnosis of Type 1 diabetes.
