Symptoms Of High Blood Sugar That You Should Not Ignore

Most of the food that we consume is broken down into glucose. The human body uses glucose as a fuel that makes our organs, muscles, and brain function properly. Nevertheless, our body cannot use glucose until it enters our cells.  

Insulin, a hormone produced by the pancreas, unlocks the cells and the glucose enters. If the pancreas cannot produce insulin, the glucose builds up in the bloodstream and causes blood sugar levels to increase. In the long run, this causes damage to the organs, blood vessels, and nerves.  

Blood sugar spikes are common for people with diabetes because they are not able to use insulin effectively. Although there is no cure for diabetes, blood sugar spikes can be controlled with a balanced diet and medicines.  

Symptoms of High Blood Sugar 

If you learn to recognize the symptoms of high blood sugar, you will be able to keep diabetes under control. Some people with diabetes immediately detect the symptoms, whereas others go undiagnosed for years due to mild or vague symptoms. If left untreated, the symptoms get worse.  

The most common symptoms of high blood sugar that you should not ignore include: 

Increased thirst 

You are not physically active, but you are thirsty? It may be a sign of high blood sugar. 

Increased appetite 

High levels of blood sugar may increase your appetite. When glucose can’t enter the cells, the body needs another source of energy.  

Blurred vision 

If you experience blurred vision, you may have high levels of blood sugar. In this case, you should consult a doctor immediately.  

Dry skin 

Blood sugar spikes may dry out your skin. If you use a moisturizer and your skin is still dry, you should visit a doctor.  

Frequent urination 

Feeling the need to urinate often is a common sign of high blood sugar levels. The need for frequent urination occurs when the kidneys cannot process the excess sugar, getting rid of it via urine.  


Not being able to get an erection is a common symptom of high blood sugar levels. Impotence is a serious health issue that should not be ignored. Moreover, if impotence is caused by high blood sugar, it can cause serious health complications. Therefore, it is best to visit a doctor before it is late.  

Weight gain 

High levels of blood sugar may lead to weight gain. When there is no insulin, the body cannot process the excess sugar, instead storing it as fat.  


Feeling tired is one of the most common symptoms of high blood sugar levels. If you notice fatigue regularly, especially after you eat, it may be a sign of blood sugar levels.  


Headaches can be a symptom of many different things, but it is best to check it out with a doctor. Dehydration caused by high blood sugar can aggravate fatigue and trigger headaches 

Nausea, vomiting, and confusion 

These symptoms can be all signs of a life-threatening state known as diabetic ketoacidosis. It can cause nausea, vomiting, confusion, as well as stomach pain, flushed skin, or trouble breathing.  

If left untreated, diabetic ketoacidosis can be fatal. Therefore, if you experience some of these symptoms, you should seek medical help immediately.  

Dental issues 

Glucose is present in the blood and in the saliva. When there is too much of it, it allows harmful bacteria in the mouth to grow and combine with food particles to produce plaque. This causes other dental problems such as cavities, tooth decay, gum disease, gingivitis, and bad breath. If your gums are tender, swollen, and bleeding, you should visit your dentist.  

 Causes of high blood sugar 

Many things can lead to an increase in blood sugar levels in people with diabetes, including: 

  • Stress 
  • A lack of exercise 
  • An illness 
  • Eating too much 
  • Taking certain medicines, such as steroids 

How you prevent and treat high levels of blood sugar depends on the cause and the overall health. In general, it will include working with a medical expert on a plan based on lifestyle changes and medications to help you regulate your health.
