High blood sugar, also known as hyperglycemia, is a condition that occurs when the blood glucose level rises above the normal range. This medical condition can have serious implications if left untreated. Knowing the symptoms of high blood sugar is crucial for your health, as well as knowing how to reduce blood sugar and keep it within a healthy range.

All About Glucose

Glucose is a type of sugar that serves as the primary source of energy for the body’s cells. It comes from the food we eat and is transported to different parts of the body through the bloodstream. Insulin, a hormone produced by the pancreas, helps regulate the amount of glucose in the blood and ensures it is properly utilized by the cells for energy. We need glucose for various bodily functions, including energy production, protein and fat synthesis, the maintenance of healthy blood vessels, and the regulation of blood pressure. Glucose is also important for brain function and helps to maintain a healthy immune system. The body can store glucose in the liver and muscles as glycogen, which can be converted back into glucose when needed. (1)

What Happens When Blood Sugar Is Too High

While glucose is important for the normal functioning of our bodies, too much or too little will cause problems. When blood sugar levels become elevated, it can lead to a range of health problems. These include diabetes, heart disease, and kidney disease. High blood sugar levels can also cause damage to the blood vessels, nerves, and organs in your body. This can lead to complications such as heart attack, stroke, blindness, kidney failure, and amputation.

High blood sugar can be caused by various factors, including insufficient insulin production, insulin resistance, certain medications, stress, illness, or an unhealthy diet. When left untreated, prolonged high blood sugar levels can damage blood vessels and organs throughout the body.

Potential Causes of High Blood Sugar

Several factors can contribute to high blood sugar levels, including diabetes (both type 1 and type 2), hormonal imbalances, certain medications, pancreatic disorders, and stress. Understanding the underlying cause of high blood sugar is crucial for effective management and treatment.

13 Signs of High Blood Sugar

There are many signals that your body can send to you if your blood sugar is too high. If you are experiencing several of these, you should talk to your doctor as soon as possible. They will take blood and urine tests to find out if high blood sugar is the problem, or if something else is going on. The 14 most common signs of high blood sugar are:

1. Urinating Large Amounts

High blood sugar levels can cause the kidneys to work harder to filter and remove excess glucose from the blood, leading to increased urination.

2. Excessive Thirst

Frequent urination can result in dehydration, triggering feelings of excessive thirst as the body tries to replenish lost fluids.

3. Feeling Tired

When cells are unable to access glucose for energy due to high blood sugar levels, it can lead to fatigue and weakness.

4. Frequent Hunger

Inadequate glucose absorption by cells can stimulate hunger signals, causing individuals with high blood sugar levels to feel constantly hungry.

5. Dry Mouth

Dehydration resulting from increased urination can lead to dry mouth and a persistent feeling of thirst.

6. Weight Loss

Unexplained weight loss can occur when the body starts to break down muscle and fat stores for energy in the absence of sufficient glucose utilization.

7. Blurred Vision

High blood sugar levels can cause fluid imbalances in the eye, leading to temporary changes in vision clarity.

8. Recurrent Infections

Elevated blood sugar weakens the immune system, making individuals more susceptible to infections such as urinary tract infections and skin infections.

9. Slow-Healing Wounds

Impaired circulation due to high blood sugar can hinder the body’s ability to heal wounds properly, resulting in slow recovery times.

10. Deep, Rapid Breathing

In severe cases of high blood sugar, a condition known as diabetic ketoacidosis can occur, leading to deep, rapid breathing as the body attempts to compensate for acid buildup in the blood.

11. Fruity-Smelling Breath

Ketoacidosis can also cause the breath to have a sweet or fruity odor due to the presence of ketones in the bloodstream.

12. Headache

Changes in blood sugar levels can trigger headaches or migraines in individuals with high blood sugar.

13. Nausea and Vomiting

Extreme fluctuations in blood sugar levels can lead to gastrointestinal disturbances, resulting in nausea and vomiting.
