What is Diabetes? An informative diagram explaining how high blood sugar and insulin function relate to diabetes.

Let’s go step by step to understand what diabetes is, based on the information given.

First, we learn that diabetes means you have too much sugar in your blood. That’s the main idea.

Why does this happen?
→ Your body turns food into a type of sugar called glucose.
→ Glucose travels in your blood and goes to all your cells — because your cells need it for energy.
→ But glucose can’t get into your cells by itself. It needs help from a chemical called insulin.

Think of insulin like a key.
→ Insulin opens the door (your cell) so sugar (glucose) can go inside.
→ Without enough insulin, sugar stays stuck in your blood → high blood sugar → that’s diabetes.

The image shows:
- A happy “I” shape = insulin doing its job.
- A sad blue circle = body cell without sugar.
- Sugar trying to get in but can’t without insulin.
- When insulin works, sugar moves into the cell → blood sugar levels stay normal.

Also important:
→ No one knows exactly what causes diabetes.
→ You can’t catch it or give it to someone else.
→ But it MUST be treated — because high blood sugar can cause serious health problems.
→ A simple test at the doctor’s office can tell if you have it.

So, putting it all together:

Diabetes happens when your body doesn’t make enough insulin (or doesn’t use it well), so sugar builds up in your blood instead of going into your cells where it’s needed.

Final Answer:
Diabetes is a condition where there is too much sugar in your blood because your body doesn’t have enough insulin to move that sugar into your cells for energy.
