People who have type 1 diabetes may also have nausea, vomiting, or stomach pains. Type 1 diabetes symptoms can develop in just a few weeks or months and can be severe. Type 1 diabetes usually starts when you’re a child, teen, or young adult but can happen at any age.

Type 2 diabetes symptoms often develop over several years and can go on for a long time without being noticed (sometimes there aren’t any noticeable symptoms at all). Type 2 diabetes usually starts when you’re an adult, though more and more children, teens, and young adults are developing it. Because symptoms are hard to spot, it’s important to know the risk factors for type 2 diabetes and visit your doctor if you have any of them.

Gestational diabetes (diabetes during pregnancy) usually shows up in the middle of the pregnancy and typically doesn’t have any symptoms. If you’re pregnant, you should be tested for gestational diabetes between 24 and 28 weeks of pregnancy so you can make changes if needed to protect your health and your baby’s health.
