Type 1 diabetes – What’s going on in your body?

When you have type 1 diabetes, your immune system attacks cells in the pancreas that produce insulin, the hormone that helps convert glucose into energy for the body’s cells. Understand how insulin and blood sugar levels affect your body’s ability to function properly.

What is insulin?

Insulin is a hormone released by the pancreas when you eat. It helps convert glucose, or sugar, from food into your body's cells where it can be used as energy. In simple terms, when your insulin level goes up, your blood sugar level goes down. Without insulin, your body cannot make use of and absorb glucose and it stays in your blood.

The importance of balanced blood sugar levels

Having balanced blood sugar levels is important for your body to function properly. Too much or too little sugar in your blood can have some very serious consequences.

Controlling your blood sugar levels will help you reduce risks of complications like:

  • Heart attack
  • Stroke
  • Reduced eyesight, blindness
  • Kidney disease
  • Nerve problems
  • Blocked circulation in the feet
  • Foot infection

What is low blood sugar or a hypo?

Low blood sugar, also called hypoglycaemia or a “hypo”, occurs when the level of sugar in your blood drops too low. 

People with diabetes who are on insulin need to be aware of the signs of a hypo as they can be very dangerous. A severe hypoglycemic event is classified as a diabetic emergency that may lead to coma and requires assistance from another person to treat.

How to spot a hypo – common symptoms

  • Confusion
  • Shakiness or feeling sick
  • Sweating, chills and clamminess
  • Intense hunger
  • Clumsiness
  • Blurred vision
  • Slurred speech.
  • Nervousness or irritability
  • Coma

You may experience one or more of these when your blood sugar levels are too low. A family member or friend may even mention that you are acting a little strangely or look unwell.

How to manage low blood sugar episodes

If you have a hypo, you should treat it by quickly consuming something sugary, otherwise, you may lose consciousness. 

It is important to always carry something to help you treat a hypo. It’s recommended that you consume 15 grams of a carbohydrate that is absorbed quickly, such as juice, soda, sweets or glucose tablets. 

Over time, you’ll become more familiar with what low blood sugar feels like and what to do about it. Learn more about hypos here. Another opportunity to learn more about hypos is through joining the Hypo Program on www.hypoprogram.com.

If you are unsure about how to manage a hypo, please seek advice from your doctor.

What is high blood sugar or hypers?

High blood sugar, also called hyperglycaemia or a “hyper”, happens when glucose cannot enter the body cells and builds up in your blood. A hyper can be dangerous, damaging your blood vessels and reducing the supply of oxygen and nutrient-rich blood going to your body's organs and nerves. Over time, this can result in irreversible tissue damage and serious health complications.

The symptoms of high blood sugar

  • Tiredness and lethargy
  • Passing more urine than usual
  • Being very thirsty
  • Blurred vision
  • Headaches

You may experience one or more of these symptoms when your blood sugar levels are high, or a family member or friend might mention that you do not quite seem your usual self. Understand the signs a hyper, as well as some ideas to prevent it, here.

  • Check your blood sugar more often than usual, specifically before and after your meals
  • Look for patterns in your blood sugar results to understand what might be causing it
