Early Signs You Have High Blood Sugar

Brief summary: High blood sugar is when the sugar, or glucose, in your blood is higher than normal. It can be a sign of diabetes or other health problems. Some early signs of high blood sugar include thirst, frequent urination, fatigue, and blurry vision. It’s important to talk to a doctor if you notice these signs, as early treatment can help control high blood sugar.

What is High Blood Sugar?

High blood sugar, medical experts called it hyperglycemia, happens when there’s too much glucose in your blood. Glucose is the sugar your body uses for energy, and it comes from the food you eat. If you have more glucose in your blood than your body needs, it can cause problems.

Why is it a Concern?

High blood sugar is not just a number. It can cause damage to your organs, nerves, and blood vessels if it stays high for a long time. It might be a sign of diabetes, which is a serious condition that needs treatment.

Early Signs You Have High Blood Sugar

If you have high blood sugar, you might notice some of these signs:

Thirst and Frequent Urination

Feeling thirsty all the time and going to the bathroom more often than usual are common signs of high blood sugar. Your kidneys try to get rid of the extra sugar through urine, so you end up going to the bathroom more.


Are you feeling tired all the time? High blood sugar can make you feel drained and worn out, even if you have had enough sleep.

Blurry Vision

High blood sugar can cause the lenses in your eyes to swell, which might make your vision blurry. This usually gets better if your blood sugar levels go back to normal.

Slow Healing and Infections

Cuts and sores that take a long time to heal and frequent infections can also be signs of high blood sugar.

Frequent Headaches

Having headaches more often than usual might be another sign of high blood sugar.

Extreme Hunger, Even After Eating a Meal

Feeling extremely hungry, even after you’ve just eaten, can be a sign that your body is not using sugar properly for energy.

Numbness or Tingling in Extremities

Feeling numb or tingly in your hands or feet might be a symptom of high blood sugar. This can happen if high sugar levels damage the nerves.

Unintentional Weight Loss

Losing weight without trying might feel like a good thing, but it can be a sign of high blood sugar. Your body might be using muscle and fat for energy instead of sugar.

These symptoms can be confusing and might seem unrelated, but they are all connected to how your body uses sugar for energy. If you notice any of these signs, it’s a good idea to talk to a doctor, as early treatment can make a big difference in how you feel.

What Causes High Blood Sugar?

There are several reasons you might have high blood sugar:

Eating Too Many Sugary Foods

Eating lots of sugary foods and drinks can cause a quick spike in your blood sugar levels.

Not Enough Exercise

Regular exercise helps your body use sugar for energy, so skipping out on exercise can cause your blood sugar to rise.

Illness or Stress

Being sick or feeling stressed can also make your blood sugar go up.

How to Know for Sure?

If you think you might have high blood sugar, it’s important to talk to a doctor. They can do a blood test to check your glucose levels.

What Can You Do About It?

Keeping a healthy diet, staying active, and following your doctor’s advice can help keep your blood sugar under control. It’s not something to ignore, so make sure to take action if you notice any of the signs mentioned above.
