Type 2 diabetes screening by pharmacists – Some pharmacists offer short appointments where you can find out your risk of developing type 2 diabetes. You usually pay a fee for this service, which involves answering a series of questions. A diabetes screening test does not diagnose you and is not completely accurate.
Instead, it can be used as a guide. Depending on the results from this screening, you or your loved one may be advised to seek further medical help from your local GP. If you don’t appear to be at risk at the time of screening, this doesn’t mean you aren’t still at risk of developing type 2 in the future.
If you later find signs of diabetes it’s worth being screened again, or being tested for diabetes. Some pharmacists offer blood tests to diagnose diabetes, but you’ll need to pay for these unlike having them through your doctor.
How is diabetes diagnosed by a doctor?
Oral glucose tolerance test – The oral glucose tolerance test (OGTT) helps doctors detect type 2 diabetes, prediabetes, and gestational diabetes. However, the OGTT is a more expensive test than the FPG test and the glucose challenge test, and it is not as easy to give.
- Before the test, you will need to fast for at least 8 hours.
- A health care professional will take a blood sample to measure your glucose level after fasting.
- Next, you will drink a liquid that is high in sugar.
- Another blood sample is taken 2 hours later to check your blood glucose level.
- If your blood glucose level is high, you may have diabetes.
If you are pregnant, your blood will be drawn every hour for 2 to 3 hours. If your blood glucose levels are high two or more times during the OGTT, you may have gestational diabetes.

Signs, Symptoms and Diagnosis of Diabetes
- Signs, Symptoms and Diagnosis of Diabetes
The signs and symptoms of Type 1 diabetes usually develop quickly, especially in children, over a period of weeks. In babies and young children, the first indication of Type 1 diabetes may be a yeast infection that causes a severe diaper rash that’s far worse than the common red, puffy and tender skin rash.
- In young children and infants, lethargy, dehydration and abdominal pain also may indicate Type 1 diabetes.
- Once the symptoms appear, a blood test generally will reveal very high blood glucose.
- Type 2 diabetes can be detected easily during a routine screening exam and blood test.
- However, it frequently can go undiagnosed for years unless a physician draws a blood sample to check the blood glucose.
In the early stages of Type 2 diabetes, you experience few to no noticeable signs of the disease. As time goes by and the untreated blood glucose continues to rise, symptoms begin. If you’re over 40 or have parents or siblings with diabetes, be sure to have your blood glucose checked routinely.
- Extreme thirst and a greater need to urinate: As excess glucose (sugar) builds up in the bloodstream, fluid is pulled from the tissues. The loss of fluid makes you thirsty. As a result, you may drink and urinate more than usual.
- Frequent hunger: Without enough insulin to move sugar into the cells (Type 1) or insulin resistance prohibiting insulin from entering the cells (Type 2), the muscles and organs are low on energy. This triggers intense hunger.
- Weight loss: Despite eating more than usual to relieve hunger, rapid weight loss sometimes occurs. Without the energy that glucose supplies, muscle tissues and fat stores simply shrink. Unexplained weight loss is often one of the first symptoms to be noticed.
- Blurred vision: If the blood glucose is too high, fluid may be pulled from the lenses of the eyes, affecting the person’s ability to focus clearly.
- Feeling tired: If cells are deprived of sugar, you may become tired and lethargic.
- Slow-healing sores, yeast infections, urinary tract infections, etc.: High blood glucose reduces the immune system’s ability to fight infections.
Can you miss diagnose diabetes?
Discussion – Misdiagnosing type 1 diabetes as type 2 diabetes is common in older adults, and can lead to life-threatening acute metabolic decompensation, poor glucose control and diabetes complications. DKA has a one-year mortality rate of 9% and a one-year readmission rate of 36% 6, and may be accompanied by cardiovascular events 7 and organ failure.
Recurrences of DKA are preventable with appropriate treatment of insulin-deficient diabetes and awareness of sick-day management, however, a proper diagnosis of type 1 diabetes must be made, especially in patients with atypical presentation whether due to age or other factors. Type 1 diabetes is commonly misdiagnosed in adults, although data on this occurrence is limited.
A study from the Diabetes Alliance for Research in England (DARE) found that 38% of type 1 diabetes patients diagnosed over age 30 were misdiagnosed with type 2 diabetes and did not receive the required insulin 4, Testing for anti-GAD antibody and C-peptide is the first step to differentiate type 1 diabetes from type 2 diabetes.
While up to 30% of patients with type 1 diabetes will be antibody negative 8, a low C-peptide can help clarify the diagnosis 9, Whether this patient had latent autoimmune diabetes in adults is unclear, as his medical care prior to the onset of his first episode of DKA was sporadic at best. The American Diabetes Association views patients with latent autoimmune diabetes in adults as having type 1 diabetes 10,
Unfortunately, the errant diagnosis of type 2 diabetes, inappropriate treatment and poor follow-up put this patient at risk for recurrence of DKA, during which he experienced adverse events including Mallory-Weiss tears, atrial fibrillation, acute kidney injury and troponin leak.
Poor glucose control from insufficient insulin replacement has contributed to long term diabetes complications, including diabetic retinopathy and chronic kidney disease, which the patient now manifests. In addition, patients with late onset type 1 diabetes are also at higher risk for other autoimmune diseases 11 ; timely diagnosis of type 1 diabetes allows clinicians to effectively monitor patients for other autoimmunity.
Prevention of recurrent DKA and long-term complications of diabetes relies on provision of appropriate treatment to manage hyperglycemia, which is predicated on making the correct diagnosis. Patients who present with DKA, regardless of age, should have diagnostic testing to determine the etiology of their diabetes, and those with a new diagnosis of type 1 diabetes should be treated with physiologic insulin replacement.
What happens if you don’t diagnose diabetes?
Complications of Diabetes If type 2 diabetes goes untreated, the high blood sugar can affect various cells and organs in the body. Complications include kidney damage, often leading to dialysis, eye damage, which could result in blindness, or an increased risk for heart disease or stroke.
What happens if you don’t detect diabetes?
Untreated diabetes can lead to long-term complications or even death. In people with type 2 diabetes, these complications can include heart disease, kidney damage, peripheral neuropathy (nerve pain), or vision loss. The situation is more urgent for people with type 1 diabetes.
- Without insulin, they can develop a potentially fatal condition called diabetic ketoacidosis in as little as a few hours.
- Sometimes, diabetes goes untreated because it hasn’t been diagnosed.
- The Centers for Disease Control and Prevention (CDC) estimates that 7.2 million Americans have undiagnosed diabetes.
Other times, someone with diabetes doesn’t take the necessary steps to manage the condition. This article discusses the signs of untreated diabetes, the effects on the body that lead to long-term complications, and whether those complications can be reversed.
Can diabetes come on all of a sudden?
What are the symptoms of diabetes? – Symptoms of diabetes include
increased thirst and urination increased hunger fatigue blurred vision numbness or tingling in the feet or hands sores that do not heal unexplained weight loss
Symptoms of type 1 diabetes can start quickly, in a matter of weeks. Symptoms of type 2 diabetes often develop slowly—over the course of several years—and can be so mild that you might not even notice them. Many people with type 2 diabetes have no symptoms. Some people do not find out they have the disease until they have diabetes-related health problems, such as blurred vision or heart trouble,
How does a doctor diagnose type 2 diabetes?
Diagnosis – Type 2 diabetes is usually diagnosed using the glycated hemoglobin (A1C) test. This blood test indicates your average blood sugar level for the past two to three months. Results are interpreted as follows:
Below 5.7% is normal.5.7% to 6.4% is diagnosed as prediabetes.6.5% or higher on two separate tests indicates diabetes.
If the A1C test isn’t available, or if you have certain conditions that interfere with an A1C test, your doctor may use the following tests to diagnose diabetes: Random blood sugar test. Blood sugar values are expressed in milligrams of sugar per deciliter (mg/dL) or millimoles of sugar per liter (mmol/L) of blood.
Less than 100 mg/dL (5.6 mmol/L ) is normal.100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes.126 mg/dL (7 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
Oral glucose tolerance test. This test is less commonly used than the others, except during pregnancy. You’ll need to fast overnight and then drink a sugary liquid at the doctor’s office. Blood sugar levels are tested periodically for the next two hours. Results are interpreted as follows:
Less than 140 mg/dL (7.8 mmol/L ) is normal.140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L ) is diagnosed as prediabetes.200 mg/dL (11.1 mmol/L ) or higher after two hours suggests diabetes.
Screening. The American Diabetes Association recommends routine screening with diagnostic tests for type 2 diabetes in all adults age 35 or older and in the following groups:
People younger than 35 who are overweight or obese and have one or more risk factors associated with diabetes Women who have had gestational diabetes People who have been diagnosed with prediabetes Children who are overweight or obese and who have a family history of type 2 diabetes or other risk factors
