Diabetes Mellitus: Types, Causes, Symptoms & Tests

Diabetes mellitus is a medical condition in which the body becomes unable to utilize the energy produced by the food we eat. 

The pancreas is a significant organ that produces insulin, which helps the body utilize sugar for energy.

When the pancreas produces insulin, but it doesn’t work as it should be, diabetes mellitus occurs. To have a more in-depth insight into the disease, continue reading the blog, and get answers to all of your questions.

First, you need to understand how the body uses food for energy. There are millions of cells in the body. The cell requires food to produce electricity. When you consume food, a great deal of food split into a pure sugar called glucose. This glucose provides you with the energy you need to perform day-to-day activities. 

Blood vessels act as a highway and convey the sugar from where it is consumed or manufactured to the location in the body where it is utilized or accumulated. In the whole process, insulin acts as an assistant and releases the sugar into the cells to use as energy. When sugar exits the bloodstream and enters into the body cells, the sugar level of the blood lowers down. 

In the absence of insulin, sugar can’t reach to the blood cells. It increases the blood sugar level, and the condition is called diabetes.
