It’s important to know the signs your body exhibits to alert you something’s wrong so that you can consult your doctor on time.

However, the most commonly-experienced high blood sugar symptoms include:

What are the symptoms of high blood sugar?

  1. Increased thirst: Your kidneys will have difficulty functioning properly if you have high blood sugar levels. They produce more urine to help you rid your body of the excess glucose they can’t absorb. This can cause you to become dehydrated, thereby increasing your thirst for water.
  2. Always being hungry: If your blood sugar is high, you tend to eat more often. This is because glucose can’t enter your cells. You could be insulin resistant or not be getting enough insulin. If your body doesn’t feel nourished enough to produce energy, you’ll feel like eating more.
  3. Frequent urination: Urinating frequently is linked to continual thirst. Your kidneys can’t keep up with the excess sugar. They produce more urine causing you to use the convenience more often. Keep track of your number of trips to the bathroom and consult your doctor.
  4. Extreme tiredness: You become tired if you’re drinking liquids and urinating and eating, because your kidneys and body can’t keep up the cycle of creating glucose and energy.
  5. Blurred vision: The lenses of your eyes will swell if you have high blood sugar. This is usually temporary. But be certain to have a serious chat with your doctor.
  6. Dry and itchy skin: High blood sugar levels causes your nerves to become damaged because your body can’t hold liquids. You tend to use more lotions and creams to keep it soft and smooth. Dry skin is an indication that you’ve had a high blood sugar level for quite some time.
  7. Impotence: This sign pertains only to men with high blood pressure. This is directly attributed to not receiving proper blood flow to permit them to get an erection.
  8. Weight gain: Your cells don’t respond to insulin because your cells can’t get glucose from your blood. Your blood sugar levels will accumulate over time and will cause you to add on weight.

Causes of High blood sugar

What causes us to get high blood sugar in the first place?

Poor diet and eating habits: It should be a normal way of life to eating healthy, not temporary. Go for fresh foods, avoid processed and packaged foods. There are more salt and calories in these highly processed items. Your body will digest them quicker causing your blood sugar levels to increase.

Lack of exercise: You will be causing more damage to your heart, blood sugar and bones if you don’t exercise frequently. Not exercising can cause your muscles to reject insulin.

Stress: If you’re stressed out, you could also have high blood sugar levels. Stress hormones can spike your blood sugar levels. Try meditating and forcing yourself to relax.

How to reduce high blood sugar


One way to reduce blood sugar is to inject insulin. However, be careful as insulin can take 4 hours or longer to be fully absorbed, so you need to be certain of how much insulin you may already have in your body that is yet to be absorbed by the blood. Insulin that is yet to be absorbed by the blood is called ‘active insulin’.

Drinking more water

When your blood sugar level is high, your body will try to flush excess sugar out of your blood through the urine. As a result, your body will need more fluids to rehydrate itself. Drinking lots of water can help the body with flushing out some of the glucose in the blood. Note that water intoxication (which can result in death) is possible if a number of litres water are drunk in a short space of time, though this is rare.


Exercise can help you lower blood sugar level and walking is a good way of achieving this. One may think harder or more strenuous exercise would have a better effect on lowering blood sugar, but this is not always the case as strenuous exercise can produce a stress response which causes the body to raise blood glucose levels.
