Key points
- Type 1 and type 2 diabetes often develop slowly over time, and both can start with few or no symptoms.
- Gestational diabetes doesn’t usually have symptoms. Your doctor should test you for it between 24 and 28 weeks of pregnancy.
- Knowing the symptoms of diabetes can help you to manage your health and prevent complications.

Symptoms
Both type 1 and type 2 diabetes can have similar symptoms, including:
- Frequent urination (peeing).
- Increased thirst and hunger.
- Losing weight without trying.
- Fatigue (tiredness).
- Feeling irritable or moody.
- Blurry vision.
- Frequent urinary tract infections (UTIs) or yeast infections.
Symptoms of type 1 diabetes
People with type 1 diabetes in its early stages don’t have any symptoms. As type 1 progresses, symptoms can appear suddenly, in just a few weeks or months, and can be severe. People with type 1 diabetes may also have these symptoms:
- Nausea.
- Vomiting.
- Stomach pains.
- Diabetic ketoacidosis (DKA).
Type 1 diabetes is frequently diagnosed in childhood, but it can develop at any age.
Symptoms of type 2 diabetes
Type 2 diabetes symptoms often take several years to develop. Some people don't notice any symptoms at all. Type 2 diabetes usually starts when you're an adult, though more and more children and teens are developing it. Because symptoms are hard to spot, it's important to know the risk factors for type 2 diabetes.
Some additional symptoms more common in type 2 diabetes include:
- Cuts, sores, or wounds that are very slow to heal.
- Dark patches of skin around the neck, armpits, or groin.
- Numbness or tingling in the hands or feet.
Symptoms of gestational diabetes
Gestational diabetes (diabetes during pregnancy) usually doesn't have any symptoms. If you're pregnant, your doctor should test you for gestational diabetes between 24 and 28 weeks of pregnancy. If needed, you can make changes like healthy eating and being active to protect your health and your baby's health. If those changes aren’t enough to manage your blood sugar, your doctor may prescribe medicine to help.
