For the majority of healthy individuals, average blood sugar level or average blood glucose level as follows:
For people with diabetes, average blood glucose or average blood sugar targets are as follows:
After meals : under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes.
BLOOD SUGAR LEVELS IN DIAGNOSING DIABETES
Diabetes is diagnosed with fasting sugar blood tests or with A1c blood tests, also known as glycated hemoglobin tests. A fasting blood sugar test is performed after you have had nothing to eat or drink for at least eight hours.
The following table lays out criteria for diagnoses of diabetes and prediabetes.Blood sugar levels in diagnosing diabetes.
early signs of diabetes
The early signs and symptoms of type 2 diabetes can include:
1. Frequent urination
When blood sugar levels are high, the kidneys try to remove the excess sugar by filtering it out of the blood. This can lead to a person needing to urinate more frequently, particularly at night.
2. Increased thirst
The frequent urination that is necessary to remove excess sugar from the blood can result in the body losing additional water. Over time, this can cause dehydration and lead to a person feeling more thirsty than usual.
3. Always feeling hungry
People with diabetes often do not get enough energy from the food they eat.
The digestive system breaks food down into a simple sugar called glucose, which the body uses as fuel. In people with diabetes, not enough of this glucose moves from the bloodstream into the body’s cells.
As a result, people with type 2 diabetes often feel constantly hungry, regardless of how recently they have eaten.
4. Feeling very tired
Type 2 diabetes can impact on a person’s energy levels and cause them to feel very tired or fatigued. This tiredness occurs as a result of insufficient sugar moving from the bloodstream into the body’s cells.
5. Blurry vision
An excess of sugar in the blood can damage the tiny blood vessels in the eyes, which can cause blurry vision. This blurry vision can occur in one or both of the eyes and may come and go.
If a person with diabetes goes without treatment, the damage to these blood vessels can become more severe, and permanent vision loss may eventually occur.
6. Slow healing of cuts and wounds
High levels of sugar in the blood can damage the body’s nerves and blood vessels, which can impair blood circulation. As a result, even small cuts and wounds may take weeks or months to heal. Slow wound healing also increases the risk of infection.
7. Tingling, numbness, or pain in the hands or feet
High blood sugar levels can affect blood circulation and damage the body’s nerves. In people with type 2 diabetes, this can lead to pain or a sensation of tingling or numbness in the hands and feet.
This condition is known as neuropathy, and it can worsen over time and lead to more serious complications if a person does not get treatment for their diabetes.
8. Patches of dark skin
Patches of dark skin forming on the creases of the neck, armpit, or groin can also signify a higher risk of diabetes. These patches may feel very soft and velvety.
This skin condition is known as acanthosis nigricans.
