High Blood Sugar Symptoms You Shouldn't Ignore (And What to Do About Them)

High blood sugar, also known as hyperglycemia, occurs when there's too much glucose in your blood. It's a common concern, especially for individuals with diabetes, but it can also affect those without a diagnosed condition. Recognizing the symptoms of high blood sugar is crucial for timely intervention and preventing long-term health complications. In this article, we'll delve into the signs of high blood sugar, potential causes, and effective strategies for managing and lowering blood sugar levels.

What is High Blood Sugar (Hyperglycemia)?

Hyperglycemia is characterized by elevated glucose levels in the blood. Glucose, derived from the food we eat, serves as the primary source of energy for our bodies. Insulin, a hormone produced by the pancreas, helps glucose enter cells to be used for energy. When the body doesn't produce enough insulin or cannot use insulin effectively (insulin resistance), glucose accumulates in the bloodstream, leading to hyperglycemia.

Types of Hyperglycemia:

Fasting Hyperglycemia: High blood sugar levels after not eating for at least eight hours.
Postprandial or Reactive Hyperglycemia: High blood sugar levels within two hours after eating.

Common High Blood Sugar Symptoms

Being able to identify the common high blood sugar symptoms can empower you to seek timely treatment and prevent complications. While symptoms may vary from person to person, here are some of the most frequently observed signs:

Increased Thirst (Polydipsia): Persistent thirst, even after drinking plenty of fluids, is a common symptom. Your body tries to flush out the excess sugar through urine, leading to dehydration and increased thirst.
Frequent Urination (Polyuria): Needing to urinate more often than usual, especially at night, is another telltale sign. The kidneys work overtime to remove excess glucose from the blood, resulting in increased urine production.
Blurred Vision: High blood sugar can cause fluid to be pulled from the lenses of the eyes, leading to temporary blurred vision.
Fatigue: Feeling unusually tired or sluggish, even after getting sufficient rest, can indicate high blood sugar levels.
Headaches: High blood sugar can trigger headaches, which may range from mild to severe.
Slow-Healing Cuts and Sores: Elevated blood sugar can impair the body's ability to heal, leading to slow-healing cuts and sores.
Increased Hunger (Polyphagia): Despite eating, you may still feel hungry. This is because the body isn't effectively using glucose for energy.
Dry, Itchy Skin: High blood sugar can contribute to dry, itchy skin.
Recurring Infections: High blood sugar can weaken the immune system, making you more susceptible to infections, such as yeast infections and urinary tract infections.

What Causes High Blood Sugar?

Several factors can contribute to high blood sugar. It's important to understand these potential causes to take preventative measures:

Diabetes: This is the most common cause. Both type 1 and type 2 diabetes affect how the body regulates blood sugar.
Diet: Consuming a diet high in sugary foods, processed carbohydrates, and unhealthy fats can lead to elevated blood sugar levels.
Lack of Physical Activity: Insufficient physical activity can make your body less sensitive to insulin, resulting in higher blood sugar.
Stress: Stress hormones can raise blood sugar levels.
Illness: Infections and other illnesses can also temporarily increase blood sugar.
Certain Medications: Some medications, such as corticosteroids and certain diuretics, can increase blood sugar.
Dehydration: Not drinking enough water can concentrate glucose in the blood, leading to high blood sugar.
Pancreatic Issues: Problems with the pancreas, such as pancreatitis or pancreatic cancer, can disrupt insulin production.
Gestational Diabetes: A type of diabetes that develops during pregnancy.

Potential Complications of Uncontrolled High Blood Sugar

Ignoring uncontrolled high blood sugar can lead to serious health complications. These complications can be both short-term and long-term. The Color Of A Hypoglycemic Event Understanding And Managing Low Blood Sugar

Short-Term Complications:

Diabetic Ketoacidosis (DKA): A life-threatening condition primarily affecting people with type 1 diabetes. It occurs when the body starts breaking down fat for energy because there's not enough insulin to use glucose. This process produces ketones, which can build up to dangerous levels in the blood.
Hyperosmolar Hyperglycemic State (HHS): A serious condition mostly affecting people with type 2 diabetes. It's characterized by extremely high blood sugar levels and dehydration.

Long-Term Complications:

Cardiovascular Disease: High blood sugar can damage blood vessels and increase the risk of heart attack, stroke, and peripheral artery disease.
Neuropathy (Nerve Damage): High blood sugar can damage nerves throughout the body, leading to numbness, tingling, pain, and other nerve-related problems.
Nephropathy (Kidney Damage): High blood sugar can damage the kidneys, potentially leading to kidney failure.
Retinopathy (Eye Damage): High blood sugar can damage the blood vessels in the retina, potentially leading to vision loss and blindness.
Foot Problems: Nerve damage and poor circulation caused by high blood sugar can increase the risk of foot ulcers, infections, and amputations.
Skin Conditions: High blood sugar can increase the risk of bacterial and fungal infections, as well as dry, itchy skin.
Cognitive Impairment: Some studies suggest a link between high blood sugar and cognitive decline, including memory problems and dementia.

How to Manage and Lower High Blood Sugar

Managing and lowering high blood sugar is essential for preventing complications and maintaining overall health. Here are some effective strategies:

Monitor Blood Sugar Regularly: Regular blood sugar monitoring is crucial for understanding how your body responds to different foods, activities, and medications. Follow your doctor's recommendations for testing frequency and target blood sugar ranges.
Follow a Healthy Diet: Focus on consuming a balanced diet rich in fruits, vegetables, whole grains, and lean protein. Limit sugary foods, processed carbohydrates, and unhealthy fats. Work with a registered dietitian or certified diabetes educator to create a personalized meal plan.
Engage in Regular Physical Activity: Aim for at least 30 minutes of moderate-intensity exercise most days of the week. Regular physical activity helps improve insulin sensitivity and lower blood sugar levels. Consult with your doctor before starting a new exercise program.
Stay Hydrated: Drink plenty of water throughout the day to help flush out excess glucose from the blood and prevent dehydration.
Manage Stress: Find healthy ways to manage stress, such as yoga, meditation, or spending time in nature. Stress can raise blood sugar levels.
Get Enough Sleep: Aim for 7-8 hours of quality sleep per night. Lack of sleep can affect blood sugar levels.
Take Medications as Prescribed: If you have diabetes, take your medications as prescribed by your doctor. Insulin and other diabetes medications help regulate blood sugar levels.
Work with a Healthcare Team: Collaborate with your doctor, registered dietitian, certified diabetes educator, and other healthcare professionals to develop a comprehensive diabetes management plan tailored to your individual needs.

Lifestyle Adjustments

Adopting certain lifestyle adjustments can significantly help in controlling high blood sugar levels.

Portion Control: Being mindful of portion sizes can help prevent overeating and keep blood sugar levels stable.
Fiber Intake: Increase your intake of dietary fiber, which slows down the absorption of sugar and helps regulate blood sugar levels.
Regular Meals: Eating regular meals and snacks throughout the day can help prevent blood sugar spikes and crashes.
Limit Alcohol Consumption: Alcohol can affect blood sugar levels. If you choose to drink alcohol, do so in moderation and with food.

The Role of Medication

Medication plays a significant role in managing high blood sugar, especially for individuals with diabetes. The specific medications prescribed will depend on the type of diabetes and the individual's needs.

Medication Type	How it Works	Examples
Insulin	Replaces or supplements the body's own insulin production, allowing glucose to enter cells.	Insulin lispro (Humalog), Insulin aspart (Novolog), Insulin glargine (Lantus)
Metformin	Decreases glucose production in the liver and improves insulin sensitivity.	Glucophage, Fortamet, Riomet
Sulfonylureas	Stimulate the pancreas to release more insulin.	Glipizide (Glucotrol), Glyburide (Glynase), Glimepiride (Amaryl)
DPP-4 Inhibitors	Help increase insulin release and decrease glucagon secretion.	Sitagliptin (Januvia), Saxagliptin (Onglyza), Linagliptin (Tradjenta)
SGLT2 Inhibitors	Increase glucose excretion in the urine.	Canagliflozin (Invokana), Dapagliflozin (Farxiga), Empagliflozin (Jardiance)
