Doctors Say Patients Should Look Out for These 7 Symptoms of Uncontrolled Diabetes

The symptoms of uncontrolled blood sugar in type 2 diabetes include frequent urination, constant tiredness, and fatigue.

If you have diabetes, managing glucose levels can reduce your risk of complications. If levels remain outside your target range, diabetes can not only affect the quality of life, it can be life-threatening. For help in managing your glucose levels, ask your doctor about the Eversense® CGM System, a device that monitors glucose every five minutes for up to 90 days at a time and automatically alerts in case of low and high glucose levels.

According to Medical News Today, the American Diabetes Association (ADA) notes that healthy blood sugar levels are usually:

  • Before meals: 70–130 mg/dl.
  • Two hours after eating: under 180 mg/dl.

Uncontrolled Diabetes Symptoms

Keeping your diabetes under control is crucial. In this article, we discuss seven symptoms of uncontrolled diabetes that doctors say patients should look out for.

1. Frequent Infections

The body’s immune system can be affected by high blood sugar levels from diabetes, increasing vulnerability to infections. People with diabetes have a higher risk of skin, mouth, ear, and gastrointestinal infections, yeast infections, and flu. See your health care provider if you notice more frequent infections or if it takes longer for you to recover.

2. Increased or Frequent Urination

If you’re urinating more often than usual, this could be cause for concern. Polyuria, when someone expels at least three quarts of urine per day, is a common sign of diabetes. It’s caused by the body’s attempt to expel excess sugar through the urine. People drink more when sugar levels are high, resulting in an increase in urine.

3. Increased Thirst

When blood sugar levels are very high, a person may experience increased thirst. Also known as polydipsia, a person may feel extreme thirst, dizziness, and even a chronically dry mouth. Dehydration can occur from high blood sugar levels. Dehydration can still occur even if you increase your water intake.

4. Constant Tiredness and Fatigue

Extreme tiredness and fatigue are symptoms of uncontrolled blood sugar. According to Very Well Health, common reasons diabetics can feel fatigued include stress resulting from the diagnosis or management of diabetes, being overweight or obese, depression, sleep problems, chronic pain, hyperglycemia, and other diabetes symptoms. See your health care professional if this problem persists.

5. Cardiovascular Symptoms

Cardiovascular disease is often a complication of diabetes. According to HealthGrades, risk factors for heart disease include high cholesterol levels and obesity. Poor circulation can contribute to slow wound healing and problems in the extremities, such as the feet. Important warning signs of cardiovascular disease include abnormal heart rhythms, high blood pressure, and chest pain.

6. Legs Cramp or Ache

Pain in your legs can be caused by poor circulation. Try taking a short walk, soaking your legs in a warm Epsom salt bath, or using a stationary bike for better circulation and to help reduce muscle aches, pains, and spasms.

7. Dizzy and Lightheaded

Possible causes of lightheadedness and dizziness in diabetics include dehydration, low blood pressure, high blood sugar, and certain medications. If you suffer from recurrent or persistent bouts of dizziness, see your health care provider.

Paying attention to your body is the best indicator for continued optimal health. Watching out for these seven warning signs of uncontrolled diabetes can ultimately save your life.
