Type 2 diabetes is strongly linked with
being overweight especially carrying too much weight around the
middle, and with being inactive.
Having a family history of type 2
diabetes also increases your risk.
The signs and symptoms of type 2 diabetes
aren’t always as obvious. It’s often diagnosed during a routine
check-up at the GP.
And, although the symptoms are often mild and
develop gradually over a number of years, there are a few tell-tale
signs.
If you have any of these symptoms or you know someone who does go and get checked out by your GP.
Hunger and fatigue
Your body and brain cells rely on a tiny
sugar called glucose to provide the fuel they need to function properly.
Your body tries to regulate your blood glucose level and keep it within
very narrow limits.
To physically enter the cells and provide
nourishment, your body needs the hormone insulin. Insulin ‘holds hands’
with glucose to get it into where it needs to be.
If your body becomes
resistant to insulin, which can happen when there is too much fat in
your cells (this distorts the shape of the membranes making it difficult
for insulin to enter them) and the hormone can’t do its job and your
cells become deprived of nourishment. The result? Hunger and tiredness.
Thirst and frequent trips to the loo
Your body likes to hang on to the
nutrients it receives and so it will reabsorb glucose. But when there’s
too much glucose circulating around your blood (if insulin is absent or
not working properly, for example), your body can’t reabsorb all of it.
To get rid of the extra glucose, your body makes more urine. But for
this to happen, it needs more fluid hence an increase in thirst.
Drinking more means you need to urinate more, too. The glucose spills
out in urine (diabetes means siphon – to pass through and the Latin word
mellitus means honeyed or sweet!)
Because your body concentrates on trying
to get rid of the excess glucose in your body through urine, there’s
less fluid to go around for the rest of your body. The result can be a
dry mouth and/or a strange, lingering taste. This can be due to less
saliva production (saliva is your mouth’s natural cleansing system). Dry
mouth can make dental problems worse so as well as seeing your GP,
keeping up with visits to your dentist is vital, too. Also, because your
kidneys are using so much fluid to get rid of excess glucose, there may
be less fluid around to reach your skin. Dry, annoyingly itchy skin can
result.
Blurred vision
As your body battles with fluid and
glucose, the fluid in your eyes can be affected. Dryness can mean that
the lenses in your eyes alter in shape making focussing more difficult
and leading to blurred vision.
Infections
Millions of microorganisms live in
harmony in and on your skin and that includes yeast organisms. But, if
circumstances are right, yeast infections like candida and athlete’s
foot can flourish and grow out of control since they love glucose and
moist, warm conditions. That’s why recurrent yeast infections may be a
sign of diabetes.
Slow of Wounds
Blood carries the nutrients and infection
fighters needed to promote wound healing. But, fluctuations in blood
flow caused by fluid levels can slow down wound healing.
On top of this,
high levels of blood glucose can affect the nerves leading to poor
blood circulation. All of this makes it harder for blood to reach the
wound or cut, which slows down wound healing.
Diagnosing and treating type 2 diabetes
is very important. Your GP can give you a quick check-up and test for
diabetes. And, treatment can help you stay well and help you avoid nerve
damage, heart trouble, and other complications later on.
