Diabetes Mellitus


Diabetes Mellitus (DM) is a chronic metabolic disease. The pancreas does not produce enough insulin or the body cannot use insulin effectively. As a result, sugar accumulates in the blood and the excess sugar is excreted in the urine.


Types of DM


  1. Type 1 diabetes: It accounts for 5% to 10% of DM patients. It is more common among children and young adults. Due to failure of the pancreas,
  2. Type 2 diabetes: About 90% to 95% of diabetic patients belong to this type. It mainly affects the middle-aged or elderly, especially those with family history, obesity, poor eating habit or lack of exercise. The body fails to produce enough insulin or the use is ineffective. Symptoms usually develop gradually and some people may have no obvious symptoms in the early stage.
    Treatment depends on the severity of the disease. For mild cases, diet control with appropriate exercise may already suffice. Others would need oral hypoglycemic drugs. For those poorly controlled patients, insulin may be required.
  3. Gestational diabetes: These women develop diabetes during pregnancy, which subsides after delivery. They have higher risk of developing type 2 diabetes later.
  4. Secondary diabetes: It refers to diabetes that is caused by other diseases (e.g. mumps, chronic pancreatitis or long term use of steroids).




Some patients have no obvious symptoms, and the condition is only found during health checks. Common symptoms include:

  • frequent urination and excessive thirst
  • tiredness and unexplained weight loss
  • itchiness of skin especially private parts
  • poor wound healing




Acute complication: Loss of consciousness may occur when the blood sugar is too high (diabetic ketoacidosis, hyperosmolar nonketotic coma) or too low (hypoglycemic coma). These are emergency situations and the patient should be sent to the hospital right away

  • Chronic complication: Long term high blood sugar damages the blood vessels and can cause serious health complications, such as coronary heart disease, hypertension, kidney failure, cataract and retinal degeneration. These can lead to blindness, stroke, chronic skin ulcer or gangrene, which may require amputation if not treated properly. Thus, a well-controlled blood sugar level is of utmost importance to reduce the risk of long term complications.




  • Maintain an optimal weight : Insulin works better if the excess body weight is cut down.
  • Eat a healthy diet: Avoid food with high calorie and high sugar content so that the demand for insulin is reduced. For some mild cases, patients only require diet control.
  • Regular exercise : This helps the overweight patient to lose weight, it also improves blood circulation which helps to prevent further complications.
  • Drug treatment : This includes oral hypoglycemic agent and insulin. Always take the drug as advised to avoid any adverse effects

In addition, patient should pay attention to lifestyle modification. Remember, a regular routine in terms of meals, rest, and work life balance, no smoking and regular follow-up are essential to control diabetes and prevent complications.




Healthy lifestyle is the best defence to reduce the risk of developing diabetes. It includes balanced diet, optimal weight control, regular exercise, no smoking and wise alcohol drinking.
