Early Signs and Symptoms of Diabetes

Foods to Control Your Blood Sugar

Early Signs and Symptoms of Diabetes

How can you tell if you have diabetes? Most early symptoms are from higher-than-normal levels of glucose, a kind of sugar, in your blood.

The warning signs can be so mild that you don't notice them. That's especially true of type 2 diabetes. Some people don't find out they have it until they get problems from long-term damage caused by the disease.

With type 1 diabetes, the symptoms usually happen quickly, in a matter of days or a few weeks. They're much more severe, too.

Early Signs of Diabetes

Both types of diabetes have some of the same telltale warning signs.

Hunger and fatigue. Your body converts the food you eat into glucose that your cells use for energy. But your cells need insulin to take in glucose. If your body doesn't make enough or any insulin, or if your cells resist the insulin your body makes, the glucose can't get into them and you have no energy. This can make you hungrier and more tired than usual.

Peeing more often and being thirstier. The average person usually has to pee between four and seven times in 24 hours, but people with diabetes may go a lot more. Why? Normally, your body reabsorbs glucose as it passes through your kidneys. But when diabetes pushes your blood sugar up, your kidneys may not be able to bring it all back in. This causes the body to make more urine, and that takes fluids. The result: You'll have to go more often. You might pee out more, too. Because you're peeing so much, you can get very thirsty. When you drink more, you'll also pee more.

Dry mouth and itchy skin. Because your body is using fluids to make pee, there's less moisture for other things. You could get dehydrated, and your mouth may feel dry. Dry skin can make you itchy.

Blurred vision. Changing fluid levels in your body could make the lenses in your eyes swell up. They change shape and can’t focus.

Symptoms of Type 2 Diabetes

These tend to show up after your glucose has been high for a long time.

Yeast infections. Both men and women with diabetes can get these. Yeast feeds on glucose, so having plenty around makes it thrive. Infections can grow in any warm, moist fold of skin, including:

Between fingers and toes

Under breasts

In or around sex organs

Slow-healing sores or cuts. Over time, high blood sugar can affect your blood flow and cause nerve damage that makes it hard for your body to heal wounds.

Pain or numbness in your feet or legs. This is another result of nerve damage.

Symptoms of Type 1 Diabetes

You might notice:

Unplanned weight loss. If your body can't get energy from your food, it will start burning muscle and fat for energy instead. You may lose weight even though you haven't changed how you eat.

Nausea and vomiting. When your body resorts to burning fat, it makes ketones. These can build up in your blood to dangerous levels, a possibly life-threatening condition called diabetic ketoacidosis. Ketones can make you feel sick to your stomach.

Shaky

Nervous or anxious

Hyperglycemia

Hyperglycemia, or high blood sugar, causes many of the warning signs of diabetes listed above, including:

Heavy thirst

Blurry vision

Peeing a lot

More hunger

Numb or tingling feet

Fatigue

Sugar in your urine

Weight loss

Vaginal and skin infections

Slow-healing cuts and sores

Blood glucose over 180 milligrams per deciliter (mg/dl)

Diabetic Coma

Its official name is hyperosmolar hyperglycemic nonketotic syndrome (HHNS). This serious complication can lead to diabetic coma and even death with either type of diabetes, though it’s more common in type 2. It happens when your blood sugar gets too high and your body gets severely dehydrated. Symptoms include:

Blood sugar over 600 mg/dl

Dry, parched mouth

Extreme thirst

Warm, dry skin that doesn’t sweat

High fever (over 101 F)

Sleepiness or confusion

Vision loss

Hallucinations

Weakness on one side of your body

When to Call Your Doctor

If you're older than 45 or have other risks for diabetes, it's important to get tested. When you spot the condition early, you can avoid nerve damage, heart trouble, and other complications.
