Final answer:
The first sign of type 1 diabetes is often ketoacidosis. This complication arises when the body, due to the lack of insulin, starts to burn fat for energy and produces excess ketone bodies, leading to symptoms such as excessive thirst and urination, as well as a noticeable smell of acetone on the breath.
Step-by-step explanation:
The First Sign of Type 1 Diabetes
The first sign of type 1 diabetes is often ketoacidosis. In individuals with type 1 diabetes, the immune system destroys insulin-secreting beta cells in the pancreas, leading to a lack of glucose control in the blood. Because of the insufficient production of insulin, glucose remains in the blood instead of being used by the cells, which in turn causes the body to metabolize fat for energy. This process results in the release of fatty acids and an overproduction of ketone bodies, leading to ketoacidosis. Signs of ketoacidosis include frequent urination, excessive thirst, the smell of acetone on the breath, nausea, vomiting, and abdominal pain.
A person who is diabetic and uses insulin, such as someone with type 1 diabetes, can initiate ketoacidosis if a dose of insulin is missed. This is a dangerous complication and can be prevented with careful management of insulin therapy.
If a student or individual notices signs of ketoacidosis, it's imperative to seek medical help immediately as it can be life-threatening if not treated promptly.
