To know if you have diabetes, watch for signs like increased thirst/urination, fatigue, hunger, blurred vision, slow-healing sores, and weight loss (Type 1) or gain (Type 2); however, Type 2 often has no symptoms, so a doctor's blood sugar test (like A1C or fasting glucose) is essential for diagnosis.
Early signs of diabetes often include increased thirst and frequent urination, extreme hunger, fatigue, blurred vision, slow-healing sores, and unexplained weight loss (especially Type 1) or weight gain (Type 2), but Type 2 symptoms can be mild or absent, so regular checkups are key. Tingling in hands/feet, frequent infections (yeast, UTIs), and mood changes can also appear.
A finger prick test using a home testing kit or data from a continuous glucose monitor may show you have high blood sugar levels but won't confirm you have diabetes. You'll need a blood test sent to a laboratory to diagnose diabetes. A normal blood test result will show you don't have diabetes.
Diabetes often starts with mild symptoms such as feeling very hungry and tired, needing to pee a lot, being very thirsty, having a dry mouth, itchy skin, and blurry vision. Type 1 diabetes symptoms appear quickly and are more severe, while type 2 symptoms develop slowly.
Symptoms of hyperglycaemia
High blood sugar (hyperglycemia) often feels like extreme thirst, frequent urination, and constant tiredness, with other signs including blurred vision, headaches, irritability, and sometimes nausea or unexplained weight loss, as your body struggles to use sugar for energy. These symptoms arise because sugar builds up in your blood, pulling fluids from tissues, leading to dehydration and fatigue.
Drink more water
“Water helps your kidneys filter out excess sugar through urine,” says Khan. “So, the more hydrated you are, the more urine production you'll have, which flushes out sugar in the body.” Always opt for water instead of sugary drinks, like soda and juice.
You can develop type 2 diabetes at any age, even during childhood. However, type 2 diabetes occurs most often in middle-aged and older people. You are more likely to develop type 2 diabetes if you are age 45 or older, have a family history of diabetes, or are overweight or have obesity.
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.
To manage diabetes, avoid sugary drinks, refined carbs (white bread, pasta, rice), processed foods, sweets (candy, cakes), unhealthy fats (fried foods, trans fats, high-fat dairy), and limit red/processed meats, while focusing on fiber-rich, whole foods. Key is to control blood sugar spikes by reducing added sugars, sodium, unhealthy fats, and simple carbs.
Three common signs of diabetes are increased thirst and frequent urination, extreme tiredness, and blurry vision or slow-healing sores, often stemming from high blood sugar levels affecting the body. These symptoms, sometimes called the "Three Ps" (polyuria, polydipsia, polyphagia), can develop slowly in Type 2 diabetes or quickly in Type 1.
According to its proponents, you use the pinch method by holding the thumb and index finger of one hand just above the wrist of the other hand and then exerting a little bit of pressure on the wrist. Doing this will supposedly cause the release of insulin and break down glucose.
Your provider would diagnose you with prediabetes if your: Fasting plasma glucose test result is 100 to 125 mg/dL (normal is less than 100; diabetes is 126 or higher). A1C result is 5.7% to 6.4% (normal is less than 5.7%; diabetes is 6.5% or higher).
Five common signs of prediabetes include increased thirst/urination, constant fatigue, blurry vision, dark skin patches (acanthosis nigricans), and slow-healing cuts or frequent infections, though prediabetes often has no noticeable symptoms, making early detection key. These signs often signal higher blood sugar levels, indicating your body isn't using insulin effectively.
Stage 1: Normal Blood Sugar
Stage 1 is now considered the start of T1D. Individuals test positive for two or more diabetes-related autoantibodies identified by TrialNet screening. The immune system has started attacking insulin-producing beta cells, although blood sugar levels remain normal and no symptoms are present.
A diabetic belly refers to the accumulation of fat around the abdomen, often leading to a rounder or more protruding stomach. This isn't just about weight gain—it's closely linked to how diabetes affects your metabolism and fat storage.
Five early signs of diabetes include frequent urination, increased thirst and hunger, fatigue, blurry vision, and slow-healing sores or frequent infections, stemming from high blood sugar levels that affect the body's ability to use glucose for energy, leading to these common symptoms.
Many people with diabetes have peripheral artery disease (PAD), which reduces blood flow to the feet. Also, many people with diabetes have neuropathy, causing you to not feel your feet. Together, these problems make it easy to get ulcers and infections that may lead to amputation.
How do I check?
Common symptoms of diabetes:
In type 1 diabetes, the onset of symptoms can be very sudden. In type 2 diabetes, symptoms tend to begin over time, and sometimes there are no signs at all.
Diabetes can make you feel very tired. This is called fatigue. It happens because high blood sugar disrupts the body's ability to use sugar for energy. Dehydration from increased urination also can leave you feeling tired.
Boycotting sugar for 30 days can help. A diet rich in sugar is also a diet rich in oils and cholesterol. Boycotting sugar may help the body process nutrients better, hence you may also witness reduced levels of cholesterol and blood pressure.
“When we eat sugar, our blood sugar spikes and our bodies react by releasing insulin to lower it to a safe level. Often, the insulin brings blood sugar levels down too low which can cause fatigue, irritability and hunger,” Masoud explains.
Just 2 minutes of walking after eating can help blood sugar, study says. Getting up and moving after you eat -- even if it's only for two minutes -- can help control blood sugar levels, a new study says. If you can't do that, try standing. It helps, too.
