Symptoms of Diabetes Mellitus

Symptoms of Diabetes Mellitus describes what is diabetes, the signs of diabetes and what type 1 and type 2 diabetes symptoms to watch for.

What is Diabetes Mellitus?

Diabetes Mellitus is a disorder in which there is too much sugar in the blood. It is caused by the lack of an important hormone called insulin, which is made by a gland behind the stomach called the pancreas. Insulin controls the balance of sugar (Glucose) in the body. It tends to increase as we get older because the pancreas, like other organs, tends to wear out.

What are the two main Diabetes types?

Diabetes Mellitus Type 1 - Diabetes type 1 is known as juvenile-onset diabetes or insulin-dependent diabetes mellitus. It occurs mainly in young people, and because their pancreases produce very little insulin, they require injections of insulin.

Diabetes Mellitus Type 2 - Diabetes type 2 is known as maturity-onset diabetes or non-insulin-dependent diabetes mellitus. It mainly affects people over 40, many of whom are overweight and have a diet with excess calories. It is usually controlled by a proper diet for diabetes only, but sometimes diabetes medicine may have to be used.

Warning Signs of Diabetes

The classical symptoms of untreated diabetes are :

  • excessive and frequent urination (every hour or so)
  • excessive thirst
  • loss of weight (mainly in type 1 diabetes)
  • tiredness and lack of energy
  • a tendency to get infections, especially of the skin

Diabetes Complications

Modern diabetes treatment is very effective for diabetes, but the results depend on the patient following the treatment especially the diet. If diabetes is untreated, the complications are very severe and include coma (from the blood sugar being either too high or too low), kidney disease, blindness and heart disease. The feet and eyes are at special risk and need special care and regular checks.
