November is Diabetes Awareness Month, an important reminder to pay attention to changes in your health that could indicate a problem with your blood sugar.
Some early signs of diabetes are easy to overlook, especially when symptoms like fatigue or increased thirst can have several possible causes.
According to the Centers for Disease Control and Prevention (CDC), many people with diabetes or prediabetes do not experience noticeable symptoms. Others may develop changes gradually, making it difficult to recognize when something is wrong.
At Pomona Valley Health Centers (PVHC), we believe understanding the early signs of diabetes is an important step toward protecting your long-term health. Knowing what to watch for and when to talk with your doctor can help you receive appropriate screening and care.
Diabetes is a chronic health condition that affects how your body uses blood sugar, also called glucose.
Glucose provides energy for your body's cells, while insulin, a hormone produced by the pancreas, helps glucose move from your bloodstream into those cells.
When your body does not produce enough insulin or cannot use it effectively, glucose can build up in your blood.
There are several forms of diabetes and related blood sugar conditions:
Although these conditions differ, recognizing changes in your health and discussing screening with your doctor can help identify potential concerns.
There are also several common misconceptions about diabetes, including assumptions about who can develop the condition and whether symptoms are always obvious.
The early signs of diabetes can vary from person to person. Some people experience several symptoms, while others may have only one or no noticeable changes at all.
According to the CDC, the following are among the most common warning signs to recognize.
Feeling unusually thirsty or needing to urinate more often than normal can be an early sign of elevated blood sugar.
When glucose builds up in the bloodstream, your kidneys work to remove the excess through urine. This can cause your body to lose more fluid, leading to dehydration and increased thirst.
You may notice that you're drinking more water throughout the day, waking up frequently to use the bathroom, or feeling thirsty even after drinking fluids.
If these changes are unusual for you, talk with your healthcare provider about whether blood sugar testing is appropriate.
Losing weight without changing your diet or exercise routine may indicate that your body is having difficulty using glucose for energy.
When cells cannot access enough glucose, the body may begin breaking down fat and muscle for fuel. This can lead to unexpected weight loss, sometimes over a relatively short period.
Unexplained weight loss is particularly common with type 1 diabetes, although it can occur with type 2 diabetes as well.
Because sudden or unexplained weight changes can have several causes, it's important to discuss them with your doctor.
Everyone feels tired occasionally, but persistent fatigue that does not improve with rest may be a sign that something is affecting your health.
When your body cannot use glucose efficiently, your cells may not receive the energy they need. Changes in blood sugar can also contribute to irritability, mood changes, and difficulty concentrating.
If you consistently feel exhausted despite getting enough sleep, or notice unusual changes in your energy levels, a healthcare provider can help determine whether diabetes or another condition may be responsible.
Changes in blood sugar levels can temporarily affect the shape of the eye's lens, making it difficult to focus clearly.
You may notice that your vision becomes blurry, changes throughout the day, or seems different for no obvious reason.
Although blurred vision can have many causes, it is important not to overlook sudden or recurring changes. Talk with your healthcare provider about appropriate evaluation and whether blood sugar testing may be needed.
Sudden vision loss or other severe, abrupt vision changes require immediate medical attention.
High blood sugar can affect circulation and the body's ability to fight infections, making it more difficult for wounds to heal.
Some people may notice that minor cuts or scrapes take longer than expected to improve. Others may experience recurring infections, including urinary tract infections, yeast infections, or skin infections.
These symptoms do not automatically mean you have diabetes, but they are worth discussing with your doctor, particularly if they occur repeatedly or alongside other warning signs.
Gestational diabetes develops during pregnancy when blood sugar levels become elevated.
Unlike some other forms of diabetes, gestational diabetes often causes no noticeable symptoms.
When symptoms do occur, they may include increased thirst or more frequent urination. However, these changes can also occur during a healthy pregnancy, making symptoms alone an unreliable indicator of the condition.
According to the American College of Obstetricians and Gynecologists, routine screening generally takes place between 24 and 28 weeks of pregnancy. Patients with certain risk factors may need testing earlier.
At Pomona Valley Health Centers, our Sweet Success Program supports patients with diabetes who are managing their condition during pregnancy through education and coordinated care.
If you are pregnant, talk with your healthcare provider about your individual risk factors and the appropriate screening schedule.
Although diabetes can affect people of different ages and backgrounds, certain factors can increase the likelihood of developing type 2 diabetes.
Common risk factors include:
Having one or more risk factors does not mean you will develop diabetes. However, understanding your personal risk can help you and your doctor decide when screening is appropriate.
For a more detailed explanation of these factors, learn more about who is at risk for diabetes.
If you notice increased thirst, frequent urination, unexplained weight loss, persistent fatigue, or other possible diabetes symptoms, schedule an appointment with your healthcare provider.
You do not need to experience several symptoms before seeking medical advice. Because type 2 diabetes and prediabetes can develop without noticeable warning signs, routine screening is also important for patients with certain risk factors.
Your family medicine provider can review your symptoms, medical history, and family history to determine whether testing is needed.
Common blood tests include the A1C test, which measures average blood sugar over approximately three months, and the fasting blood glucose test, which measures blood sugar after a period without eating. Other tests may be recommended depending on your situation.
Some symptoms require emergency care rather than a routine appointment. Severe vomiting, abdominal pain, difficulty breathing, confusion, or fruity-smelling breath may indicate diabetic ketoacidosis, a potentially life-threatening complication. Seek emergency medical attention if you experience these symptoms.
Early detection plays an important role in preventing or delaying diabetes-related complications. At Pomona Valley Health Centers, our providers offer comprehensive, compassionate care to help patients better understand their health and take appropriate next steps.
Through our preventive care and family medicine services, we can help assess diabetes risk factors, recommend appropriate blood sugar testing, and explain what your results mean.
If testing indicates prediabetes or diabetes, your provider can work with you to develop an individualized care plan based on your health needs.
Ongoing primary care also helps monitor blood sugar levels, manage related health conditions, and adjust treatment as needed. Learn more about how a primary care doctor can help manage diabetes.

Yes. Many people with type 2 diabetes or prediabetes do not experience noticeable symptoms, especially in the early stages. This is why routine screening is important for patients with certain risk factors, even when they feel healthy.
Prediabetes occurs when blood sugar levels are higher than normal but not high enough for a type 2 diabetes diagnosis. Type 2 diabetes develops when blood sugar reaches the diagnostic range for diabetes because the body cannot use insulin effectively or produce enough of it.
Identifying prediabetes can provide an opportunity to make changes that may help prevent or delay type 2 diabetes.
Healthcare providers commonly use an A1C test, fasting blood glucose test, or oral glucose tolerance test to diagnose diabetes and prediabetes.
The A1C test measures average blood sugar over approximately three months, while fasting glucose testing measures blood sugar at a specific point in time after fasting. An oral glucose tolerance test evaluates how the body processes glucose after drinking a sugary solution.
Your doctor will determine which test is appropriate and whether additional testing is needed to confirm a diagnosis.
Prediabetes can sometimes return to a normal blood sugar range through lifestyle changes, including improved nutrition, regular physical activity, and weight management when appropriate.
Some people with type 2 diabetes may also achieve remission, meaning their blood sugar remains below the diabetes threshold without glucose-lowering medication for a sustained period. However, remission is not considered a permanent cure, and ongoing monitoring remains important.
Type 1 diabetes cannot currently be reversed and requires ongoing insulin treatment.
Talk with your healthcare provider about the treatment and management options appropriate for your diagnosis.
