Symptoms of type 1 diabetes are caused by the buildup of glucose in the blood and the lack of glucose in body cells. Symptoms of hyperglycemia include the following:
In some cases, the total lack of insulin leads to a condition called ketoacidosis. When you do not have enough insulin, blood sugar levels rise. Yet, that sugar cannot enter the body’s cells to generate energy. In response, the body starts breaking down stored fat for energy. The by-products of fat breakdown are called ketone bodies. These ketone bodies are composed of acids that build up in the blood and cause ketoacidosis.
Symptoms of ketoacidosis include:
If ketoacidosis is not treated immediately with fluids and insulin, it can lead to coma and even death.
