Diabetes is one of those conditions we've all heard of – but few of us truly understand how many types there are, what the warning signs look like, or how to get tested properly. In this guide, I'll walk you through the 5 main types of diabetes, what symptoms to watch for, and how and where to get tested.

Let's clear up the confusion and help you take action, whether for yourself or a loved one.

What Is Diabetes?

In simple terms, diabetes is a condition where your blood sugar (glucose) gets too high. This happens either because your body doesn't make insulin (a hormone that helps use sugar for energy) or it doesn't use insulin properly.

If untreated, high blood sugar can damage your eyes, heart, nerves, and kidneys – but with the right diagnosis and care, it's manageable and even preventable in some cases.

How Many Types of Diabetes Are There?

You've probably heard of Type 1 and Type 2 diabetes, and maybe gestational diabetes, but there are at least five main types, plus a few rarer ones that are just as important.

Let's break them down.

The 5 Main Types of Diabetes

1. Type 1 Diabetes

  • What is it? An autoimmune condition where the body destroys insulin-producing cells. Usually diagnosed in children or young adults, but it can develop at any age.
  • Symptoms: Thirst, tiredness, frequent urination, sudden weight loss.
  • Treatment: Lifelong insulin therapy.
  • Fun fact: The life expectancy of a type 1 diabetes patient has improved dramatically with better treatments.

2. Type 2 Diabetes

  • What is it? The most common type, when the body doesn't use insulin properly or doesn't make enough.
  • Linked to: Genetics, inactivity, and being overweight.
  • Symptoms: Feeling sleepy after eating (yes, is feeling sleepy after eating a sign of diabetes? – it can be), thirst, tiredness, frequent urination.
  • Can you get rid of type 2 diabetes? You might be able to manage or even reverse it with healthy eating, weight loss and exercise.

Explore medically supervised weight loss treatments that may support blood sugar control.

3. Gestational Diabetes

  • What is it? A form of diabetes that develops during pregnancy.
  • When do you get tested for gestational diabetes? Between 24 and 28 weeks of pregnancy.
  • Risk factors: Being overweight, family history, and previous large babies.
  • Treatment: Diet changes, monitoring, sometimes medication. Usually goes away after birth, but increases the risk of Type 2 later on.

4. LADA (Latent Autoimmune Diabetes in Adults)

  • Also known as: Type 1.5 diabetes.
  • What is it? A slow-onset version of Type 1 that appears in adulthood.
  • Often misdiagnosed as Type 2, but it eventually requires insulin.

5. Type 3c Diabetes

  • What is it? Caused by damage to the pancreas from illness (like cancer or pancreatitis) or surgery.
  • Different because: It also affects digestion, as the pancreas can't make enzymes properly.

Other Types of Diabetes

Less common types include:

  • MODY (Maturity Onset Diabetes of the Young): Genetic and usually diagnosed before age 25.
  • Neonatal Diabetes: A rare type found in babies under 6 months.
  • Steroid-induced Diabetes: Triggered by certain medications like steroids.
  • Cystic Fibrosis-related Diabetes: A unique form affecting people with cystic fibrosis.
  • Wolfram and Alström Syndromes: Very rare genetic conditions that include diabetes as one of their symptoms.
