Diabetes Part 2: Symptoms

Symptoms of Type 1 diabetes can start quickly and include all of the above. Type 2 diabetes symptoms are similar but most often start slowly. And in some cases, people with Type 2 or gestational diabetes, have no signs or symptoms whatsoever. If experiencing, or witnessing in someone else, a combination of these symptoms, it's important to seek medical attention promptly. Diabetes is diagnosed relatively easily through blood and urine testing (discussed further in Part 3) and it is crucial to start and maintain treatment as soon as possible.

Frequent Urination: High sugar (glucose) levels in the blood cause excess sugar to spill into the urine pulling extra fluid with it which leads to increased urination.
Excessive Thirst: Dehydration caused by frequent urination then results in increased feelings of thirst.
Unexplained Weight Loss: Despite an increased appetite, people with diabetes may experience weight loss due to the inability to use glucose for energy and the resulting breakdown of fat as fuel for the body.
Fatigue: The inability of cells to effectively use glucose can lead to fatigue and weakness.
Tingling or loss of feeling in hands or feet: High blood sugar levels over time can cause damage to nerves affecting sensation in both hands and feet.
Blurred Vision: High blood sugar levels can progressively cause changes in vision.
Skin Changes: One of the most common signs, high glucose levels affect both nerves and blood vessels found in the skin causing changes in appearance and texture.
Delayed Healing: Diabetes can impair the body's ability to heal wounds and fight infections.

Once diabetes has been diagnosed and treatment begun, there are still factors and situations that will trigger the development of hyperglycemia. Examples include the following:
