Diabetes type 2 is caused by the pancreas not producing enough of the hormone insulin.
Without enough insulin, sugar stays in the blood and isn’t converted into fuel for the body.
Having high blood sugar levels can lead to hyperglycaemia, a condition that triggers the main symptoms of diabetes.
These are the five main diabetes symptoms that you should be aware of.
“If you experience any of these symptoms on a regular basis, talk to your doctor,” said medical website Healthline.
“They may recommend that you be tested for diabetes, which is performed with a basic blood draw.”
Hyperglycaemia can cause the eyes’ lens to become swollen.
A swollen lens leads to blurred vision.
“Getting your blood sugar under control can help correct vision problems,” said the medical website.
“If blood sugar levels remain high for a long time, other eye problems can occur.”
Seeing as glucose isn’t converted into energy, and remains in the blood, more fluid is forced from cells.
That means more fluid is delivered to the kidneys, which makes patients urinate more frequently.
Urinating more often could also lead to dehydration.
Feeling very thirsty
While everyone becomes thirsty if you haven’t had enough water, diabetes patients suffer excessive thirst, even after drinking lots.
As the body urinates more frequently, your tissues become dehydrated quicker.
“Increased thirst is another common diabetes symptom. The more you urinate, the more you need to drink, and vice versa,” said Healthline.
Infections that keep coming back
Small cuts and sores may take longer to heal in diabetes patients.
High blood sugar makes it harder for the body to heal injuries.
Open sores are more likely to develop infections.
Feeling very hungry
If the body isn’t producing enough insulin, or the body isn’t reacting to the hormone, glucose stays in the blood and isn’t converted into energy.
“This lack of energy causes an increase in hunger,” said Diabetes.co.uk.
“Simply eating will not get rid of the hungry feeling in people with uncontrolled diabetes, as this will just add to the already high blood glucose levels.”
