Symptoms of type 1 diabetes are serious and usually happen quickly, over a few days to weeks, and can include:
Increased thirst or hunger
Increased urination or bedwetting
Fatigue
Unexplained weight loss
Irritability or behavioral changes
Blurred vision
Fruity-smelling breath
Diabetic Ketoacidosis
Sometimes, the first signs of type 1 diabetes are symptoms of a serious condition called diabetic ketoacidosis, when the body can’t make enough insulin. Without insulin, the body starts using fat for energy. This causes acids called ketones to build up in the blood.
If not treated, this can lead to diabetic ketoacidosis, which is very dangerous. Ketones can build up to high levels and become a life-threatening condition, leading to coma or death. Symptoms of diabetic ketoacidosis include:
Dry or flushed skin
Nausea or vomiting
Stomach pain
Trouble breathing
Trouble paying attention or feeling confused
Symptoms of diabetic ketoacidosis can become immediately life-threatening (signs of severe high blood sugar, dehydration, confusion, rapid breathing, or other concerning symptoms), so it is critical to seek emergency care right away.
