Type 2 diabetes is a common condition in the UK and is usually caused by a person being overweight or obese.
The condition can lead to serious health complications, such as heart attack and stroke, so it’s important to recognise any symptoms as early as possible.
Some of the more common symptoms of type 2 diabetes are increased thirst, peeing more than usual and blurred vision.
But there are also three more unusual signs of type 2 diabetes you should be aware of.
Hearing loss has also been linked to diabetes in various research studies, according to Diabetes.co.uk.
It explains: “Health experts and medical researchers have debated the possible link between diabetes and hearing loss since the 1960s and early attempts to establish such as association were not very convincing.
“But in recent years there has been growing evidence to suggest diabetes contributes to hearing loss.”
So how does diabetes cause hearing loss?
The diabetes expert says while it is unknown exactly why hearing loss is more common among people with diabetes, autopsy studies of diabetes patients suggest the association is caused by neuropathy (nerve damage).
Neuropathy is a common complication of type 1 and type 2 diabetes.
It says: “Researchers believe prolonged high blood glucose levels may lead to hearing loss by affecting the supply of blood or oxygen to the tiny nerves and blood vessels of the inner ear.
“Over time, the nerves and blood vessels become damaged, affecting the person’s ability to hear.”
“People with diabetes have an increased risk of developing gum disease. Poorly managed blood sugar levels can cause damage to nerves, blood vessels, the heart, the kidneys, the eyes and the feet. In the same way, the gums can too be affected,” adds the diabetes expert.
“Because high blood sugar levels lead to damage to blood vessels, this reduces the supply of oxygen and nourishment to the gums, making infections of the gums and bones more likely.
“Uncontrolled blood sugar levels can cause levels of glucose to rise in the saliva and this creates a breeding ground for bacteria, increasing the risk of gum disease and dental decay.”
Severe gum disease can then negatively affect blood sugar control and can increase the chances of diabetes complications happening.
In findings presented in 2016 at the European Association for the Study of Disease annual meeting, it was revealed people who took daytime naps longer than an hour were 45 per cent more likely to have type 2 diabetes compared to those who napped less or not at all.
The study authors added it’s not likely that napping during the day actually causes diabetes.
But they said it could be a warning sign of an underlying health problem, such as sleep deprivation or depression, which are all conditions associated with an increased risk of diabetes.
