Let’s compare the early symptoms of diabetes, how they differ between type 1 versus type 2, in males versus females, and in children versus adults.
These symptoms are shared between type 1 and type 2 diabetes. However, the types develop at very different speeds. This causes symptoms to present very differently.
Diabetes symptoms are the results of high blood sugar levels in the body.
These symptoms develop suddenly in type 1 diabetes. Type 2 diabetes often develops slowly over many years.
Common early symptoms include:
It’s more common to develop type 1 diabetes in childhood or adolescence, but it does sometimes develop in adulthood.
Since the symptoms of type 1 diabetes come on so quickly, they’re generally severe and noticeable. For example, you might lose a dramatic amount of weight in just a few weeks. You might also have stomach pains and vomiting.
Additionally, because type 1 diabetes develops rapidly, your blood sugar might become very high before you can get a diagnosis and start treatment. This can sometimes lead to a medical emergency called ketoacidosis that requires immediate care.
You could have type 2 diabetes for years without any symptoms. When symptoms do start, they’ll often be mild. It’s easy to dismiss them or mistake them for other conditions.
Over time, people with type 2 diabetes develop higher and higher levels of glucose in the blood, which can cause:
Sex isn’t a factor in most diabetes symptoms. However, a few additional symptoms only occur in people with a vagina. This group has a higher risk of both yeast infections and urinary tract infections (UTIs).
Most of the symptoms of diabetes are the same in infants, children, and adults. However, infants and very young children won’t be able to communicate their symptoms.
Instead, parents or caregivers will notice symptoms. You might notice:
- an increased need for diaper changes
- weight loss
- having very little appetite
- always seeming to be thirsty
- always feeling tired or weak
- changes in mood
- diaper rashes that don’t heal
- breath that has a fruity smell
- fast breathing
Just like in adults, the early symptoms are the same no matter the type: Type 1 symptoms will come on much faster. Type 2 symptoms will develop more slowly.
Diabetes can affect multiple body areas. This includes the following:
- Eyes: Diabetes often causes blurry vision. Diabetes that isn’t managed well can lead to vision loss.
- Skin: Diabetes can make it much harder for your body to heal cuts, scrapes, and other wounds. This can put you at a higher risk of infection.
- Bladder: Diabetes can cause frequent urination and increase your risk of UTIs.
- Feet: Diabetes can reduce blood flow to your feet, which makes it difficult for you to feel cuts and scrapes on your feet. It also reduces your body’s ability to heal those wounds.
- Arms and legs: Diabetes can lead to diabetic neuropathy, pain, and numbness in your arms and legs.

The symptoms of type 1 and type 2 diabetes start the same.
However, type 2 diabetes symptoms come on slowly over several years. They’re often milder at first.
Type 1 symptoms develop rapidly over just a few weeks. They’re generally more severe.
Both types of diabetes can lead to additional symptoms over time that can affect your eyes, limbs, feet, and skin.
Although they might not be able to express this, children and infants have the same symptoms as adults. Parents and caregivers can keep a lookout for any concerning symptoms.
