Diabetes Types

Know detailed information on diabetes, diabetes symptoms, signs, type 1 diabetes, type 2 diabetes



Signs and Symptoms

Both type 1 and type 2 diabetes exhibit the same basic symptoms of hyperglycemia. Some symptoms, such as tingling or burning in the hands and feet , are the result of long term uncontrolled blood glucose, and are more common in type 2 patients. It's important to note that not all people with type 2 diabetes will have symptoms, particularly in the early stages of the disease. In fact, up to a third of all Americans with type 2 diabetes are unaware that they have it.

Symptoms of type 2 diabetes may include one or more of the following:

  • Thirst and frequent urination
  • Dry, itchy skin
  • Headache
  • Tingling or burning pain in the feet, legs, hands, or other parts of the body
  • High blood pressure
  • Mood swings
  • Fatigue, or a feeling of being "run down" and tired
  • Blurred vision
  • Extreme hunger
  • Unexplained weight loss
  • Frequent or recurring infections
  • Slow healing of cuts and bruises

E Fact

Women of reproductive age who have developed polycystic ovarian syndrome (PCOS) are at an increased risk for type 2 diabetes. pcas is a hormonal disorder characterized by enlarged ovaries containing fluid filled cysts. Women with pcas have irregular menstrual cycles and high circulating levels of male hormones . Insulin resistance and impaired glucose tolerance are manifestations of pcas.

Hyperglycemic Hyperosmolar Nonketotic Coma

When blood glucose levels exceed 600 mg/dl , a condition known as hyperglycemic hyperosmolar nonketotic coma (HHNC) may occur. In HHNS, the body becomes severely dehydrated and fluids are depleted from the bloodstream. Older adults tend to develop HHNS more readily, although the condition can occur at any age.

HHNS is life threatening and requires immediate medical attention. Symptoms of the syndrome include:

  • Dehydration
  • Excessive thirst
  • Nausea and vomiting
  • Fever
  • Hypotension (low blood pressure that may be signaled by dizziness or faintness)
  • Disorientation
  • Sudden excessive sleepiness
  • Seizures
  • Visual disturbances and/or hallucinations
  • In extreme cases, coma or hemiplegia (paralysis or weakness on one side of the body)
