What is Diabetes?

Diabetes, often referred to by Doctors as Diabetes Mellitus describe a group of metabolic diseases in which the person has high blood glucose ( blood sugar ), either because insulin production is inadequate, or because the body`s cells do not respond properly to insulin, or both. Patients with high blood sugar will typically experience polyuria ( frequent urination ), and hungry ( polyphagia ).


Here are some key points about diabetes;

  • Diabetes is a long-term condition that causes high blood sugar levels.
  • In 2013 it was estimated that over 382million people throughout the world had diabetes ( Williams textbook of endocrinology )
  • Type 1 diabetes:- the body does not produce insulin. Approximately 10% of all diabetes causes are type 1.
  • Type 2 Diabetes:- the body does not produce enough insulin for proper function. Approximately 90% of all cases of diabetes worldwide are of this type.
  • Gestational Diabetes:- this type affects females during pregnancy.
  • The most common diabetes symptoms include frequent urination, intense thirst and hunger, weight gain, unusual weight loss, fatigue, cuts and bruises that do not heal, male sexual dysfunction, numbness and tingling in hand and feet.
  • If you have Type 1 and follow a healthy eating plan, do adequate exercise, and take insulin, you can live a normal life.
  • Type 2 patients need to eat healthily, be physically active, and test their blood glucose. They may also need to take oral medication, and or insulin to control blood glucose levels.
  • As the risk of cardiovascular disease is much higher for a diabetic, it is crucial that blood pressure and Cholesterol levels are monitored regularly.
  • As smoking might have a serious effect on Cardiovascular health, diabetics should stop smoking.
  • Hypoglycemia:- low blood glucose can have a bad effect on the patient.
  • Hyperglycemia:- when blood glucose is too high, can also have a bad effect on the patient.


The vast majority of patients with Type 2 Diabetes initially had prediabetes. Their blood glucose levels where higher than normal, but not high enough to merit a diabetes diagnosis. The cells in the body are becoming resistant to insulin.                                                                                                      Studies have indicated that even at the prediabetes stage, some damage to the circulatory system and the heart may already have occurred.


Keeping blood glucose, blood pressure and blood fat levels under control will greatly help to reduce the risk of developing complications.                                                                                                                               Regular check-ups are essential to help manage the condition.

  1. While now you may play free Power Rangers game
    online, don’t assume all can excel with it. You need to
    be very attentive especially when the length of the snake has increased.

    Definitely an improvement over the pitiful single-screen multiplayer of Fable 2.
