Type 2 diabetes is a common condition where the body does not produce enough insulin. Insulin regulates how the body uses and stores sugar (glucose) and fat.
It also helps the cells of the body take glucose out of the blood, after which it changes into energy.
The condition is often caused by a person who is overweight or obese, but many people with type 2 diabetes will not realize that they have it because the symptoms do not necessarily make you feel unwell.
If left untreated, serious complications can occur, such as kidney problems and nerve damage.
A warning sign to watch out is clearly visible in the hands or feet.
Tingling pain or numbness in these parts of the body can indicate the condition, according to the American Diabetes Association.
Diabetes can cause neuropathy – a long-term complication affecting the nerves – due to high blood glucose levels that damage the small blood vessels that nourish the nerves.
"This prevents essential nutrients from reaching the nerves, causing nerve fibers to become damaged or disappear," Diabetes UK explains.
Another symptom of type 2 diabetes to note is drinking lots of water, but how much does it cost a lot of water?
People with type 2 diabetes can develop polydipsia, which is the term given to excessive thirst.
"An increased thirst in people with diabetes can sometimes, but certainly not always, be an indication of higher than normal blood glucose levels," explains Diabetes.co.uk.
Health guidelines advise to drink six to eight glasses of fluid per day.
Water, skim milk and sugar-free drinks, including tea and coffee, all count.
But if you are thirsty all the time, or your thirst is stronger than normal and persists even after you have drunk, this may be a sign that not everything is well in your body.
Distinctive symptoms of polydipsia are recognized as a persistent and unexplained thirst, no matter how much you drink.
The passing on of more than five liters of urine per day can also be an indication for polydipsia.
Other symptoms of type 2 diabetes, according to the NHS, can be:
- More peeing than normal, especially at night
- Lose weight without trying
- You feel very tired
- Itching around your penis or vagina, or repeatedly getting thrush
- Cut or wounds take longer to heal
- Blurry sight
Those who are diagnosed with the condition, plus those who want to prevent this, are advised to make simple changes to their diet, such as counting the amount of carbohydrates they eat.
A healthy diet helps control blood sugar levels, and a recent study showed that a certain drink before breakfast can be beneficial.
