I've been a diabetic since I was young.
I'm sorry to hear that!  Do you have increased thirst and hunger when your blood sugar is high?
I do!  What causes that?
Sometimes it's because enough insulin isn't being produced by the pancreas
That's what my doctor said.  What happens when I don't have enough insulin?
If you don't have enough insulin then your blood sugar would get too high.
So how can I mitigate that?
well you can either try to manage it with your diet or take injections of insulin
How often do I have to inject insulin?
Insulin (medication)
Insulin is a protein hormone that is used as a medication to treat high blood glucose. This includes in diabetes mellitus type 1, diabetes mellitus type 2, gestational diabetes, and complications of diabetes such as diabetic ketoacidosis and hyperosmolar hyperglycemic states. It is also used along with glucose to treat high blood potassium levels. Typically it is given by injection under the skin, but some forms may also be used by injection into a vein or muscle.
The common side effect is low blood sugar.

Diabetes mellitus – group of metabolic diseases in which a person has high blood sugar, either because the pancreas does not produce enough insulin, or because cells do not respond properly to the insulin that is produced, a condition called insulin resistance. The resultant high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger
