Symptoms of diabetes
Symptoms of Type 2 diabetes can begin so gradually that people may not know
that they have it. Symptoms of type-2 diabetes include:
High blood glucose level (
hyperglycaemia
)
Glucose in urine (
glycosuria
)
Frequent thirst — as the body uses urine to get rid of excess glucose
Increased urination
Fatigue, drowsiness
Blurred vision
Infections that will not heal quickly
Sometimes nausea and vomiting
Women may also complain of urinary tract infections or vaginal itching
People with type-1 or type-2 diabetes are at higher risk of contracting
respiratory, urinary tract and skin infections than people without diabetes.
The first two of these symptoms willl not be noticed by the person with
diabetes, but should be picked up by a doctor on a routine check-up. The rest
may well be noticed. If you have any of them, then ask your doctor for a blood
test.
It is the third and fourth symptoms — increased thirst and urination
— that are usually noticed first. When glucose is abnormally high, the
body will attempt to combat this high level of glucose in the blood by drawing
water out of the cells and into the bloodstream in an effort to dilute the
sugar and excrete it in the urine.
It is not unusual for people with undiagnosed diabetes to be constantly
thirsty, to drink large quantities of water, and to urinate frequently as their
bodies try to get rid of the extra glucose.
