Type 2 diabetes could be caused by the body not producing enough of the hormone insulin, or the body not reacting to insulin.
Without enough of the hormone, the body struggled to convert sugar in the blood into usable energy.
It’s crucial that if you think you may have diabetes, you speak to a doctor as soon as possible.
But, it may be difficult to know if you’re at risk, especially as some of the symptoms may be difficult to spot.
“The symptoms of type 2 diabetes develop slowly, and many individuals are asymptomatic with the condition often picked up incidentally or during health check-ups,” said Vas.
“The three most common symptoms include increased thirst, a higher frequency of urination [especially at night] and increased hunger.
“Less well recognised symptoms include unintended weight loss, constant fatigue, blurry vision, headaches, and frequent infections such as thrush or skin infections or wounds that take time to heal.
“Not infrequently, the existence of type 2 diabetes is picked up when individuals simply present with a major complication of diabetes – such a heart attack, stroke or a foot ulcer.”
