A Simple Guide to Diabetes Mellitus

A Simple Guide to Diabetes Mellitus
-------------------------------------------



What is Diabetes?
---------------------



Diabetes mellitus literally means sweet urine.
It is a common chronic disease which happens when the hormone insulin produced by the pancreas is missing, lacking or not working well.


Insulin unlocks the cell to allow glucose from the bloodstream to enter the body cells for usage or storage.
When this mechanism fail, the high amount of glucose in the blood leads to the glucose being spilt over into the urine, causing diabetes.


What are the different types of diabetes?
-----------------------------------------



The main types of diabetes are
1.Type 1
2.Type 2.



Type 1 occurs commonly in children and young adults although it may occur at any age.
It is more serious because there is practically no insulin produced due to damaged pancreatic cells and therefore insulin injections is needed for treatment.
The cause is unknown.
Complications are more sudden and life-threatening.

Type 2 is
more common.
It is found in
1.adults over 40 years old,

2.overweight and

3.physically inactive.



The insulin produced is not enough or may not be working effectively.
Type 2 diabetes can be controlled by
proper dieting and exercise.
Most Type 2 diabetics will also need oral medication.


Gestational diabetes occurs only in pregnancy but may be an indicator of diabetes later in life

How does diabetes cause complications in the body?
--------------------------------------------------------------



The high blood glucose concentration in diabetes reduces the blood flow to many organs and nerves resulting in many organ damage especially the kidney, heart, brain, eyes and nerves.

The high blood glucose
allows germs to proliferate because the glucose provides nutrition to the germs.
