Type 2 diabetes can wreak havoc on the body when blood sugar levels aren’t properly managed, yet the warning signs can be easily missed in the early stages.

The health condition frequently goes undetected for a considerable length of time because the symptoms, including tiredness and frequent urination, are commonly dismissed as normal daily experiences.

Over time, untreated type 2 diabetes can result in diabetic neuropathy, which means nerve damage. The Mayo Clinic explains that peripheral neuropathy, the most prevalent type of diabetic neuropathy, typically affects the feet first, reports Surrey Live.

“Signs and symptoms of peripheral neuropathy are often worse at night,” warn the clinic.

Nevertheless, these serious complications can mostly be prevented. Regular foot examinations are strongly advised by the charity Diabetes UK.

The charity states that everyone with diabetes should receive an annual foot examination at their GP surgery.

It’s vital to recognise the general symptoms of type 2 diabetes for an early diagnosis. Unfortunately, numerous people are living with type 2 diabetes without realising it.

“This is because symptoms do not necessarily make you feel unwell,” the NHS clarified.

Symptoms of type 2 diabetes include extreme fatigue and unexplained weight loss

Symptoms of type 2 diabetes include: frequent urination (especially at night), constant thirst, extreme fatigue, unexplained weight loss, itching around your private parts or recurrent thrush, delayed healing of cuts or wounds, and blurred vision.

Beyond these warning signs, if you have concerns about your risk of developing type 2 diabetes, the NHS advises speaking to a GP.

Following a formal diagnosis, your GP will typically recommend lifestyle adjustments to help keep blood sugar levels in check.

Diet and exercise are two fundamental factors in managing blood sugar.

“Diabetes won’t stop you from enjoying your food, but knowing some simple hacks and swaps will help you choose healthier options and make planning your meals a little easier,” Diabetes UK explains.
