Study: Type 1 Diabetes Misdiagnosed in 25% of Patients
People who suffer from type 1 diabetes face a lifetime of managing blood sugar levels due to loss of insulin. This disease is incurable and the onset can begin during childhood. While some researchers point to genetics, the cause of type 1 diabetes remains unknown.
According to a study published in the July 2019 issue of Clinical Diabetes, children with a heightened likeliness of diabetic ketoacidosis (DKA) are at a greater risk of being misdiagnosed for type 1 diabetes.
The study was led by Cynthia Munoz, Ph.D., from the University of Southern California in Los Angeles. With the help of her colleagues, she identified adults and parents of children with type 1 diabetes by collecting data from the T1D Exchange clinic registry. The study involved 2,526 online survey participants who reported their diagnosis experiences.
The study results
At the time of diagnosis, participants reported experiencing:
- Excessive thirst (88.1%)
- Excessive urination (82%)
- Fatigue (74.8%)
In addition, two-thirds of participants reported that they were hospitalized at the time of diagnosis. More than 40 percent of them experienced DKA — most of them were pediatric patients.
More than two-thirds of children who were misdiagnosed experienced DKA. Another 42.8 percent were properly diagnosed.
Among adult patients, 39 percent were misdiagnosed — three-quarters of which were incorrectly diagnosed with type 2 diabetes.
“Our retrospective online survey found that 25 percent of all participants were misdiagnosed and that misdiagnosis was associated with an 18 percent increased risk for DKA compared to those correctly diagnosed,” the study authors explained.
Health effects of incorrect diagnosis
Ensuring that patients are properly diagnosed for type 1 diabetes is critical. If patients don't receive the right treatment, it can have devastating and potentially life-threatening consequences.
According to WebMd, if patients aren't properly treated for type 1 diabetes, they may experience:
- Retinopathy: This condition — which damages eyesight — usually affects roughly 80 percent of adults who have had type 1 diabetes for more than 15 years. Preventing retinopathy requires adequate control of blood sugar, blood pressure, cholesterol, and triglycerides.
- Kidney damage: This condition, also called nephropathy, affects about 20-30 percent of people with type 1 diabetes. The first signs usually appear between ages 15-25 and can lead to kidney failure and heart disease.
- Poor blood circulation and nerve damage: People with type 1 diabetes may experience nerve damage and hardened arteries which can limit blood supply to the feet. This can potentially lead to loss of a limb.
We expect highly trained doctors to possess the tools and knowledge to accurately diagnose serious conditions, such as type 1 diabetes. Failure to do so can be hazardous to the health of patients. In some cases, a misdiagnosis can be fatal.
