What happens if cells do not get insulin?

Without insulin, cells in the body cannot take up glucose from the bloodstream. This leads to a build-up of glucose in the blood, a condition known as hyperglycemia. Over time, high blood sugar levels can damage blood vessels and organs, leading to serious complications such as heart disease, stroke, kidney disease, blindness, and nerve damage.

Here's a closer look at what happens when cells do not get insulin:

1. Glucose builds up in the bloodstream: Insulin is the key that allows glucose to enter cells. Without insulin, glucose cannot get into cells and remains in the bloodstream.

2. Cells are deprived of energy: Cells use glucose as their primary source of energy. Without glucose, cells cannot function properly and start to break down.

3. Ketones are produced: In the absence of glucose, the body starts breaking down fat for energy. This process produces ketones, which can build up in the blood and cause a condition called ketoacidosis. Ketoacidosis is a serious medical emergency that can lead to coma and death.

4. Organs and tissues are damaged: High blood sugar levels can damage blood vessels and organs, leading to various complications such as heart disease, stroke, kidney disease, blindness, and nerve damage.

It is important for people with diabetes to carefully manage their condition by taking insulin or other medications as prescribed, following a healthy diet, and exercising regularly. This can help prevent or delay the onset of complications and maintain overall health and well-being.
