After you eat a snack or meal, the sugar levels in your body naturally increase for approximately one to two hours. When your body has digested the consumed foods, your sugar levels typically fall back to normal. Certain people can develop consistently high sugar levels in the blood or urine--a condition called hyperglycemia--which can be a symptom of diabetes. Talk with your doctor if you develop high sugar level symptoms to ensure that you receive appropriate treatment and care.
Increased Urination and Thirst
If you have high sugar levels, you might begin to urinate more frequently and may experience increased thirst, explains the American Diabetes Association. Sugar and other waste products are removed from your body in the form of urine. High sugar levels will trigger your body to produce more urine to clear this waste from your body. Increased fluid loss due to frequent urination can lead to thirst stimulation. You can notice that you are drinking more fluids than usual or that you can't quench your thirst if you have high sugar levels.
Fatigue
High sugar levels within the body overwhelm your cells, tissues and organs, preventing them from using this sugar for energy. When your body cannot use sugar for energy, you can begin to experience excessive tiredness or fatigue. Fatigue can make it difficult for you to remain focused and alert during your daily activities and may negatively affect your productivity at work or school.
Hunger
If you have high sugar levels, your body cannot effectively use this sugar to produce energy. As a result, your body mistakenly believes that you need to eat in order to increase your energy levels. Constant hunger can develop as a high sugar level symptom in certain patients. You can begin to feel hungry shortly after eating a snack or meal and may need to eat several small meals throughout the day to satiate your hunger.
Weight Loss
When your body cannot use sugar to produce energy due to excessively high sugar levels, it begins to use fat and muscle cells for energy, explains Kids Health, a children's health information website established by The Nemours Foundation. This can cause you to experience significant and unintended weight loss as a symptom of high sugar levels in your body.
Headache or Dizziness
You can experience a headache or dizziness when sugar levels are high, according to the New York State Department of Health in Albany. Dizziness can occur in conjunction with temporary vision changes such as blurred or cloudy vision. You can notice that you feel anxious, weak or irritable, which can worsen headache symptoms. Headache or dizziness often occurs in conjunction with other high sugar level symptoms such as hunger or fatigue.
