Signs & Symptoms of Diabetes

Diabetes is a common but often misunderstood condition, and for many, the early signs can be easy to miss. Recognizing the symptoms early is key to getting the right treatment and preventing complications. In this post, we’ll break down the most common signs of diabetes, so you know what to look for and when it’s time to talk to your healthcare provider.

Working in the clinic, I often discussed patients’ signs and symptoms with them. However, many patients usually miss the signs and symptoms that can be telltale signs of the beginning of diabetes. While some signs and symptoms of type 1 and type 2 diabetes overlap, the most important thing to remember is to pay attention to your body and not ignore what it’s trying to tell you. And for those caring for kids, it’s even more important to recognize these signs and symptoms, as they can be the difference between life and death, as Shannon Allen can attest. That’s why it’s critical to attend your yearly checkups and pay attention to what your body is trying to tell you.

Common Signs of Diabetes

Diabetes can develop gradually, and many people don’t realize they have it until symptoms become more noticeable. Recognizing the common signs—such as increased thirst, frequent urination, fatigue, and blurred vision—can help you catch it early. Additionally, common signs that can be detected through bloodwork and at your routine checkups may appear before you even notice common symptoms. These include:

• HgbA1c >5.7%
• Fasting Blood Glucose >100 mg/dL
• Unexplained weight loss (while this can be a sign for other diseases, this is a common one for diabetes, as the cells are ‘starving’.
• Positive ketones in the urine

Common Symptoms of Diabetes

Diabetes often comes with a set of symptoms that can be easy to overlook at first. From frequent urination to unexplained fatigue, these signs are your body’s way of signaling that something may be off with your blood sugar levels. Understanding the common symptoms is a crucial first step toward early detection and effective management. It’s important to note as well that symptoms of type 1 diabetes can present rapidly and, if left untreated, can be deadly. Whereas symptoms for type 2 diabetes can develop more slowly, increasing the likelihood of causing damage internally. For both type 1 and type 2 diabetes, it’s imperative to see your doctor if you or your loved one is experiencing any of these symptoms (remember, each person will present symptoms differently):

• Sudden weight loss
• Frequency urination along with excessive thirst (if left untreated, can lead to diabetic ketoacidosis)
• Unexplained fatigue
• Blurred vision (if blood sugar levels are not managed over time, this can lead to diabetic retinopathy)
• Tingling in the fingers and toes (if blood sugar levels are not managed over time, this can lead to diabetic neuropathy)
• Hair loss and dry skin
• Nausea
• Wounds that take a long time to heal and/or won’t heal
• Yeast infections
• Dry mouth

Prediabetes

Prediabetes often develops silently, without any apparent signs or symptoms. That’s because blood sugar levels rise gradually, not sharply enough to trigger obvious warning signs. Many people may not realize they have prediabetes until it’s detected through routine blood work. This is why regular check-ups and screening are so important. Early detection gives you the chance to make changes before it progresses to type 2 diabetes.

A key driver behind prediabetes is insulin resistance. Insulin resistance occurs when the body’s cells fail to respond effectively to insulin, making it more difficult to maintain normal blood sugar levels. The good news? Insulin resistance can often be improved with lifestyle changes. Regular physical activity, balanced meals rich in fiber and protein, effective stress management, and even modest weight loss can help the body become more sensitive to insulin again, thereby lowering blood sugar levels and reducing the risk of progressing to type 2 diabetes.

Summary

Understanding the early signs and symptoms of diabetes is one of the most powerful steps you can take toward protecting your long-term health. If something feels “off,” trust your body and get checked—early detection truly makes a difference. And remember, you’re never alone in this journey. With the right support, information, and care, diabetes can be managed confidently and proactively.
