Diagnosis of diabetes mellitus (DM)

Diabetes is diagnosed by the combination of history, examination, and investigations.


  • Positive family history for DM.
  • Complaints that are indicating high blood sugar level, for instance, increased urination and thirst.
  • Symptoms related to complications, such as repeated skin infections and loss of teeth.


Manifestations of increased glucose level as well as its complications, for example, dehydration and abscesses.


  • Fasting blood glucose level. It should be 70-99 mg/dl, i.e.: less than 100 mg/dl.
  • Two hours after-meal blood glucose level. It shouldn’t exceed 180 mg/dl.
  • Fat profile in the blood. It includes serum levels of cholesterol, triglycerides, the good and bad cholesterol.
  • Detection of the blood acidity by analysis of the blood gases.
  • Investigations related to complications, such as acidosis and stroke.

Prediabetes glucose level

It diagnoses the state of pre-diabetes, which means that the blood level of glucose is higher than normal, but not reaching the diabetes level yet.

 The prediabetes phase indicates that the patient has a low tolerance to glucose, and is at high risk to develop DM.

The prediabetes blood sugar ranges between 100-128 mg/dl.

It doesn’t mean that the person is having obvious manifestations suggestive of DM, but the test is done for screening of DM among at-risk people most of the time.

Sometimes it is detected accidentally upon regular check-up or routine investigations before surgery.

What are the risk factors?

  • A high blood level of blood fat, cholesterol, and triglycerides.
  • Sedentary life.
  • Being hyperglycemic during a previous pregnancy, that’s to say gestational diabetes.
  • Polycystic ovary syndrome.

What are the manifestations?

  • Drinking and urinating more than usual.
  • The sensation of weakness and fatigue.
  • Blurred vision.

What to do if diagnosed as having prediabetes?

Prediabetes state is not indicating starting treatment with insulin or glucose-lowering medications but means to do some preventive strategies to postpone DM as possible.
