Symptoms
Your (or your child's) symptoms of
type 1 diabetes probably developed quickly, over a few
days to weeks. These symptoms are caused by blood sugar levels rising above the
normal range (hyperglycemia) and include:
- Frequent urination, which may be more
noticeable at night. If your child has already learned to use the toilet, he or
she may have started wetting the bed during naps or at night. The kidneys are
trying to get rid of the excess sugar in the blood. In order to do that, they
have to excrete more water. More water means more urine.
- Extreme
thirst and a dry mouth. This happens if you lose, through frequent urination,
enough water to become dehydrated.
- Weight loss. This happens
because you are dehydrated. Weight loss may also happen if you are losing all
of those sugar calories in your urine instead of using
them.
- Increased hunger. You feel hungry because your body is not
using all the calories that it can. Many of them are being excreted in
urine.
- Blurred vision. Your vision may blur when sugar builds up in
the lens of your eye. The sugar sucks extra water into your eye, which changes
the shape of the lens and blurs your vision.
- Fatigue. You feel
tired for the same reason you feel hungry. Your body is not using the calories
you are eating, and your body is not getting the energy it needs.
All of these symptoms will get better or go away when your
blood sugar levels are controlled.
If your blood sugar rose to
very high levels at the time you were diagnosed with diabetes, you may have
received treatment in a hospital for
diabetic ketoacidosis, which is an emergency.
What symptoms might I have now?
Now that you are
taking
insulin injections, watch for signs of either high or
low blood sugar. High blood sugar (hyperglycemia) usually develops slowly over
a few days or weeks. But it can also develop quickly (in just a few hours) if
you eat a large meal or miss an insulin dose. On the other hand, low blood
sugar (hypoglycemia) can develop within 10 to 15 minutes. Children, especially
very young children, are at greater risk for harm caused by very low blood
sugar levels.
Watch for the following symptoms of high or low
blood sugar. You (or your child) may not have the same symptoms every time, and
you may have symptoms that are not listed.
