The High-Sugar Alert: Recognizing the 12 Key Symptoms Your Body Is Showing You
High blood sugar, medically known as hyperglycemia, can develop gradually. In some people, especially those with type 2 diabetes, blood sugar may remain elevated for a long time without obvious symptoms. In others, the body begins sending noticeable warning signals.
Recognizing these signs can be important because persistent high blood glucose can eventually damage the eyes, kidneys, nerves, heart and blood vessels.
Here are 12 symptoms that may occur with high blood sugar or diabetes.
1. Frequent Urination
One of the classic signs of elevated blood sugar is needing to urinate more often than usual.
When there is too much glucose in the bloodstream, the kidneys try to remove some of that excess glucose through urine. This pulls additional water into the urine, which can increase urine production.
If you suddenly find yourself waking repeatedly during the night to urinate or making frequent bathroom trips during the day, particularly when this is accompanied by increased thirst, it is worth discussing with a healthcare professional.
2. Excessive Thirst
Frequent urination can cause the body to lose more fluid than usual.
As a result, you may experience persistent thirst or a dry feeling in your mouth. Simply drinking more water does not necessarily solve the underlying problem if elevated blood glucose continues to cause excessive fluid loss.
Increased thirst and urination occurring together are particularly recognizable warning signs of diabetes.
3. Unusual or Persistent Fatigue
Feeling tired after a poor night’s sleep or a stressful day is normal. Persistent, unexplained fatigue is different.
When glucose cannot effectively enter cells and be used for energy, you may feel unusually weak or exhausted. High blood sugar can therefore be associated with tiredness and weakness.
If fatigue continues despite adequate sleep and normal daily activity, don’t automatically blame it on diet or lack of exercise. Several medical conditions can cause fatigue, including diabetes.
4. Blurred Vision
Temporary changes in blood glucose can affect the fluid balance in the tissues of the eye, which may result in blurred vision.
You might notice that objects look less sharp or that your vision seems to fluctuate.
Blurred vision can have many causes, however, so it should not automatically be attributed to high sugar. Persistent or sudden changes in vision deserve medical evaluation.
5. Increased Hunger
Some people with diabetes experience unusually strong hunger, even after eating.
This can happen because glucose is not being used effectively by the body’s cells. The body may essentially signal that it needs more energy even though there is already plenty of glucose circulating in the bloodstream.
Increased hunger is a recognized symptom of diabetes, although it can also occur for many other reasons.
