5 Common Signs of High Blood Sugar


The human body’s blood naturally contains sugar or glucose. The optimal level of blood sugar provides energy to the cells and organs of the body. Hyperglycemia refers to high blood sugar levels.

High glucose levels in the blood might cause health concerns. Therefore, you need to know the signs of high blood sugar.

1. Fatigue

Perhaps the most prevalent early indicator of elevated blood sugar is fatigue. It may also occur to a lesser extent with the usual and moderate blood sugar swings in people without diabetes (or prediabetes) when they take a substantial quantity of simple carbohydrates, such as sugar.

Fatigue is a rather general symptom (and might even indicate low blood sugar). Suppose you often experience exhaustion immediately after eating, particularly a carbohydrate-heavy meal. In that case, it may be due to increased blood sugar levels.

If you suspect that your blood sugar levels are high, you need to visit your doctor. You don’t want to wait around until the issue worsens or until you have other metabolic syndrome complications.

2. Blurry Vision and Headaches

You may notice that your vision is not as clear as it once was, and objects may look hazy. High blood sugar levels may cause your eyes to swell due to fluid leakage. In addition, you may experience regular headaches.

3. Frequent Urination

When blood sugar levels are high, the kidneys attempt to eliminate excess sugar from the blood by filtering it out. This might result in increased urination frequency, especially at night.

4. Increased Appetite

Many individuals with uncontrolled high blood sugar experience increased appetite, a condition known as polyphagia. If your blood sugar levels are too high, you may lose weight while eating more.

Since your body cannot get energy from its preferred source, glucose, it must utilize muscle and fat for fuel. When the body begins to break down muscle and fat for energy, unplanned and harmful weight loss occurs. In addition to these weight and hunger changes, you may have muscular weakness and more frequent falls.

5. Ketoacidosis

These seemingly unrelated symptoms indicate a rare and potentially fatal condition known as diabetic ketoacidosis. It often affects those with type 1 diabetes and is frequently the first symptom of illness.

Diabetic ketoacidosis (DKA) occurs when the liver cannot use the sugar in the blood for energy without insulin and starts to break down body fat into a kind of fuel known as ketones at such a rapid pace that they become poisonous and make the blood acidic. Untreated DKA may be lethal, so anybody experiencing these symptoms should seek medical attention immediately.


Above are five signs that may indicate that you have high blood sugar. If any of these symptoms apply to you, you need to immediately schedule an appointment with your doctor.
