Brits have been urged to “look out” for the signs of any foot problems.
Some lesser-known symptoms in the feet could indicate a potentially fatal disease. These unusual signs could indicate diabetes.
Diabetes is a serious and typically lifelong ailment that results in blood sugar levels becoming dangerously elevated. Although it can be managed with medication and lifestyle changes, it can be life-threatening if not treated.
Whilst the exact cause of type 1 diabetes remains unknown, type 2 diabetes is commonly associated with factors including excess weight and insufficient physical activity, although it can also be hereditary.
As with any medical condition, the earlier diabetes symptoms are identified, the quicker medical assistance can be secured. However, these warning indicators may emerge in some surprising locations.
Due to elevated blood sugar levels, the feet are one area of the body that can experience changes. Diabetes UK says: “Over time raised blood sugar levels, also known as blood glucose levels, can damage the small blood vessels that supply the nerves in your feet.
“This stops essential nutrients reaching the nerves. If the nerves in your feet are damaged, you can lose the feeling in your feet, known as peripheral neuropathy (nerve damage). This means you may not feel things properly and can damage your feet without noticing.
“Damaged blood vessels also reduce the blood supply to your feet, meaning you may then have problems with cuts and sores healing. You may also get cramps and pain in your legs or feet.”
The charity advises people to consult their GP if they observe any of the following indicators:
- Tingling sensation or pins and needles-like numbness
- Burning pain
- A dull ache
- Loss of feeling in your feet or legs
- Swollen feet – you might notice that putting your shoes on or walking has become more difficult
- Your feet don’t sweat
- Cuts, wounds or sores that don’t heal
- Cramp in your calves when resting or walking
- Shiny, smooth skin on your feet
- Hair loss on your legs and feet
Diabetes can also lead to nerve damage in the toes, resulting in conditions like:.
- Claw toe, where the toes are bent into a claw shape
- Hammer toe, where the joint on your toe points up instead of lying flat
- Corns, which are a build-up of thick layers of skin on the top or sides of your toes
- A bunion, which is a hard lump at the bottom of the big toe on the side, causing the big toe to point at an angle
In recent years, foot amputations have become increasingly common in the UK. From 2015 to 2018, there were 27,465 lower limb amputations related to diabetes in England, marking a significant increase of 18.3 per cent from 2011 to 2014.
Major amputations, defined as below the knee, rose by 8.8 per cent, while minor amputations, defined as below the ankle, increased by 22.4 per cent. Diabetes UK said: “A matter of hours can make the difference between losing and keeping a foot.
“This is why it’s vital for all people living with diabetes to know how to look after their feet, to check them regularly to look out for the signs of foot problems and to know when to seek medical attention.”
Other signs of diabetes to watch out for include:
- Excessive thirst
- Frequent urination, especially at night
- Extreme tiredness
- Weight loss and loss of muscle bulk
- Itching around the penis or vagina, or frequent bouts of thrush.
- Blurred vision
If you notice any of these symptoms, it’s vital to consult your GP.
