This was about how to diagnose diabetes with the help of signs and symptoms, and tests.
There are several ways to diagnose diabetes. Most people with type 1 diabetes and many with type 2 diabetes will present with symptoms of diabetes such as: increased thirst, urination and tiredness. Some people will also have signs of slow healing of wounds or persistent infections. Each way usually needs to be repeated on a second day to diagnose diabetes.
In incidences of prediabetes, there are no symptoms. People may not be aware that they have type 1 or type 2 diabetes because they have no symptoms or because the symptoms are so mild that they go unnoticed for quite some time. However, some individuals do experience warning signs, so it’s important to be familiar with them.
Fasting Plasma Glucose
This blood test is taken in the morning, on an empty stomach. A level of 126 mg/dl or above, on more than one occasion, indicates diabetes.
Casual or Random Glucose
This blood test can be taken anytime during the day, without fasting. A glucose level of 200 mg/dl and above may suggest diabetes.
How Are Diabetes and Prediabetes Diagnosed?
The following tests are used for the diagnosis of diabetes:
- A fasting plasma glucose test measures your blood glucose after you have gone at least 8 hours without eating. This test is used to detect diabetes or prediabetes.
- An oral glucose tolerance test measures your blood sugar after you have gone at least eight hours without eating and two hours after you drink a glucose-containing beverage. This test can be used to diagnose diabetes or prediabetes.
- In a random plasma glucose test, your doctor checks your blood sugar without regard to when you ate your last meal. This test, along with an assessment of symptoms, is used to diagnose diabetes, but not prediabetes.
How is diabetes diagnosed?
Diabetes is diagnosed by a blood test. Most people with type 1 diabetes and many with type 2 diabetes will present with symptoms of diabetes such as: increased thirst, urination and tiredness. Some people will also have signs of slow healing of wounds or persistent infections. However many people with type 2 diabetes have no symptoms at all.
The blood test is taken from a vein and sent to a pathology lab. The test may be either a fasting test (no food or fluid except water for eight hours), e.g. overnight, or a random test taken anytime during the day, or an Oral Glucose Tolerance Test (OGTT).
This was about how to diagnose diabetes with the help of signs and symptoms, and tests. However, as We have also said, for a true diagnosis, you have to undergo the tests which have been mentioned above. It is wise to do the tests as early as possible, as then you can initiate the treatment immediately thus, reducing the risks of complications.
