Top 10 warning signs for diabetes

Diabetes becomes very common all over the world and prolonged untreated diabetes can cause many health problems. If your sugar level is very high most of the time then you should seek medical help and perform some tests. You must know about the warning signs for diabetes to early diagnose type 2 diabetes.

Every food you eat adds glucose or blood sugar to your system and over time this sugar can add to your risk of becoming type-2 diabetic. High blood sugar levels can cause severe lasting and deadly damage to various organs like your kidneys and your eyes. You should keep a lookout for the top 10 warning signs for diabetes:

warning signs for diabetes

Blurry vision 

You may have some eye issues which cause you to wear glasses or contacts and that’s nothing to be worried about. But consistently high blood sugar levels or hyperglycemia can create sudden detrimental effects on your vision because it may cause fluid to leak into the lens of your eye.

Moreover, the tiny blood vessels in your eyes damage due to the high blood sugar level and cause blurry vision. Untreated diabetes can also cause blindness. If you notice a recent and dramatic change in your eyesight it might be a warning sign for diabetes from your body.

Excessive thirst and dry mouth 

Excessive thirst and dry mouth is among the common warning signs for diabetes. High glucose levels in your blood and saliva mean that your body ends up using more fluids to flush the excess sugar into your urine. When you purge it from your system using up internal fluids will make you feel thirsty and can make your mouth seem dry.

Slow-healing wounds 

Have you noticed any cuts or wounds which seemed to take forever to heal? If yes, then it’s a warning sign for diabetes. High blood sugar levels can damage blood vessels so cuts on your skin especially on your arms or legs may not get the appropriate amount of blood needed to fix those cuts quickly.


Years of loading up on sodas, chips, and cookies may lead to high glucose levels in your bloodstream which in turn can damage certain blood vessels throughout your body including your nether regions. Thus you may end up experiencing certain levels of impotence which is also a warning sign for diabetes.

Frequent urination 

When you have high blood sugar your kidneys must go into overdrive to filter the excess sugar from your blood but the kidneys end up leaving an ever-increasing amount of sugar in your bloodstream. The high blood sugar level causes your body to create more urine in an attempt to flush all that extra sugar from your system. 

This, in turn, will make you thirsty which will cause you to drink large amounts of water and the cycle continues this condition is known as polyuria or frequent releasing of large amounts of urine. If you are passing up to three liters of urine a day your body may be trying to send you a warning sign for diabetes. 

Frequent bloating

As we discussed before, large amounts of glucose in the bloodstream can cause damage to your nerves this includes the vagus nerve which controls how food moves through your stomach. When this nerve stops working normally, your stomach muscles have difficulty moving food through your digestive tract.

Hence you may begin to experience frequent amounts of bloating which is very irritating most of the time and makes you uncomfortable. 

Skin problems

High glucose levels can cause poor blood circulation and this can lead to issues with your skin. Diabetes may cause your skin to become dry itchy and you may experience rashes blisters and even fungal infections. 

Remember to check for these symptoms on your skin especially on your legs because it gives you a warning sign for diabetes.


High blood sugar levels have been shown to cause feelings of numbness in your feet as well as your hands. Diabetic neuropathy is a condition in which nerves in your hands and legs become damaged and as a consequence, you may find yourself experiencing tingling or numbness in your limps.

Frequent fatigue 

High blood sugar levels have been shown to cause feelings of exhaustion. An American Diabetes Association study revealed that over 60% of newly diagnosed type 2 diabetics reported feelings of fatigue. This condition is because as sugar builds up in your bloodstream over time your body has a harder and harder time utilizing insulin and move insulin into cells.

Insulin is a key that assures glucose from your bloodstream into your muscle cells to be used as fuel but over time damage from high sugar levels causes your body to experience increasing amounts of insulin resistance. Insulin resistance means insulin is forming properly but your body cell receptors have not the ability to utilize it. Therefore, your muscle cells will have trouble obtaining the proper amounts of that fuel.

Moreover, the medication for diabetes causes a side effect of low blood sugar levels (hypoglycemia). It means in multiple ways your cells won’t be getting their needed amount of energy and become lethargic.

Increased hunger 

As you know to have diabetes means that your insulin is not working properly and needed energy is not being effectively absorbed into your muscle cells. This lack of energy can cause not only fatigue but also hunger pangs so even though you just ate a big meal your body’s insulin resistance might make you crave more energy to compensate which is a big warning sign for diabetes.


Warning signs of diabetes include fatigue, blurry vision, frequent urination, bloating, hunger, slow healing wounds, numbness, and skin problems. If you will notice any of the above-mentioned signs you should talk to your health care provider. The timely diagnosis and treatment of diabetes improve the lifestyle and decrease the complications associated with diabetes.
