By measuring fasting blood glucose levels based on how high the levels are, it can help to diagnose some health conditions as well as help understand the severity of certain diseases.
- High fasting blood glucose levels are found in:
- Diabetes all types
- Pancreas related disorders
- Cushing’s syndrome
When the blood sugar levels increase, the condition is known as hyperglycemia. The blood sugar levels in the body rise when the pancreas cannot produce enough insulin to break down the sugar or when the body is unable to utilise the insulin properly.
Some symptoms of high blood glucose levels include:
- Fatigue and weakness
- Frequent urination
- Increased thirst
- Increased hunger
- Blurriness of vision
- Unintentional weight loss
- Frequent headaches
- Trouble concentrating
- Frequent infections
- Slower healing of wounds
If left untreated, hyperglycemia can lead to a condition called ketoacidosis diabetic coma, where the body starts breaking down body fats to produce energy. This leads to increased production of ketones, which will begin building up in the blood, causing further complications.
When the blood glucose levels fall below the normal range, the condition is called hypoglycemia. If the blood sugar levels drop below the normal range for a long time, the body is triggered to produce the ‘fight-or-flight’ hormone, adrenaline. This is what causes the blood sugar levels to drop even further.
In the case of low blood glucose levels, a few common symptoms include:
- Excess sweating
- Dryness of the mouth
- Anxiety and palpitations
- Loss of consciousness
If hypoglycemia is left untreated, the brain stops receiving glucose, and it can lead to severe complications like numbness, slurred speech, seizures, and even coma.
