What are the signs and symptoms of diabetes?


Diabetes: These are the symptoms

  • Increased thirst and urination
  • Increased hunger
  • Fatigue
  • Blurred vision
  • Numbness in the feet and hands.
  • Sores that don’t heal
  • Unexplained weight loss

Type 1 diabetes symptoms can appear quickly and may last for several weeks. Type 2 diabetes symptoms often appear slowly over several years and can be mild enough that you may not notice them. Type 2 diabetes can be silent. Many people don’t realize they have type 2 diabetes until they experience symptoms such as blurred vision and heart problems.

What causes type 1 Diabetes?


Type 1 Diabetes is when the immune system, your body’s defense system against infection, attacks the insulin-producing beta cell of the pancreas and destroys them. Type 1 diabetes may be caused by genetics or environmental factors such as viruses. Studies like TrialNet external link aim to identify the causes of type 1 diabetics and to find ways to slow down or prevent them.

What causes type 2 Diabetes?

Type 2 Diabetes – The most common type of diabetes – is caused by many factors, including lifestyle and genetic factors.

Obesity, overweight, and inactivity

Type 2 diabetes is more common in those who aren’t physically active, obese and overweight. Type 2 diabetics often have extra weight that can lead to insulin resistance. It also matters where your body fat is located. Additional belly fat can lead to insulin resistance and type 2 diabetes. These Body Mass Index (BMI), charts can help you determine if you are at risk of developing type 2 diabetes.

Insulin resistance

Type 2 diabetes is usually caused by insulin resistance. This is a condition where muscle, liver and fat cells don’t use insulin well. Your body will need more insulin to allow glucose to enter your cells. To meet the increased demand, the pancreas initially makes more insulin. As insulin production decreases, blood glucose levels increase.
