High Blood Sugar in Athens, Georgia

Athens, GA High Blood Sugar

What is high blood sugar?

High blood sugar means that the level of sugar in your blood is higher than normal. It is the main problem caused by diabetes.

The medical term for high blood sugar is hyperglycemia. Blood sugar is also called glucose.

How does it occur?

Blood sugar that stays high is the main problem of diabetes. If you have type 1 diabetes, high blood sugar happens because your body is not making insulin. Insulin moves sugar from the blood into your cells. It is normally made by the pancreas. If you have type 2 diabetes, high blood sugar usually happens because the cells have become unable to use the insulin your body is making. In both cases high levels of sugar build up in the blood.

Sometimes people with diabetes can have high blood sugar even if they are taking diabetes medicine. This can happen for many reasons but it always means that your diabetes is not in good control. Some reasons why your sugar might go too high are:

  • skipping your diabetes medicine or not taking the right amount of medicine  
  • if you are using insulin: a problem with your insulin (for example, the wrong type or damage to the insulin because it has not been stored properly)  
  • if you are using an insulin pump: a problem with the pump (for example, the pump is turned off or the catheter has come out)  
  • taking medicines that make your blood sugar medicines work less well (steroids, hormones or water pills)  
  • eating or drinking too much (that is, taking in too many calories)  
  • not getting enough physical activity  
  • emotional or physical stress  
  • illness, including colds and flu, especially if there is fever  
  • infections, such as an abscessed tooth or urinary tract infection  

Even if you don’t have diabetes, you may have high blood sugar for a brief time after you eat a food very high in sugar. For example, it might happen after you drink a large milkshake or eat a large dessert. Hyperglycemia may also happen if you have an illness that makes it hard for your body to process sugar. For example, this may happen if you have pancreatitis (an inflamed pancreas). It can also happen with some medicines, especially steroids. These conditions are usually temporary and your blood sugar usually goes back to normal after you are no longer sick or you stop taking the medicines.

What are the symptoms?

Usually hyperglycemia causes no symptoms, especially if it is brief. However, if the blood sugar rises to 300 milligrams per deciliter (16.7 millimoles per liter) or higher and stays that high for a day or longer, you may have symptoms. Symptoms may include:

  • blurry vision  
  • dry mouth  
  • feeling very thirsty  
  • drinking a lot  
  • urinating a lot  
  • tiredness.  
  • Very high blood sugar, that is, a blood sugar level of 600 mg/dL (33.3 mmol/L) or higher–can cause coma and even death.

How is it diagnosed?

The level of sugar in your blood can be measured with a blood test. The test should be done before breakfast, after several hours of no food or drink except water. This is called a fasting blood sugar test.

  • A normal fasting blood sugar is 70 to 99 mg/dL (3.9 to 5.5 mmol/L).  
  • 100 to 125 mg/dL (5.5 to 6.9 mmol/L) is mildly abnormal and is called a prediabetic blood sugar level.  
  • A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates diabetes.  

How is it treated?

The treatment depends on the cause.

Type 2 diabetes can be treated with:

  • diet  
  • exercise  
  • medicine.  

Type 1 diabetes occurs when the body (pancreas) stops making insulin. It is treated by giving the body more insulin.

Ask your Reddy Urgent Care healthcare provider what you should do if your blood sugar goes over your target, or ideal, range. If you have diabetes, your provider may have you adjust your medicine, exercise, or diet. If you have prediabetes, it is important that you learn how to use a healthy diet and regular exercise to keep from having type 2 diabetes.

Very high blood sugar above 400 mg/dL (22.2 mmol/L) can be a medical emergency. It must be treated right away with IV (intravenous) fluids and insulin. You may need to stay several days at the hospital to get your blood sugar back to normal and to treat any problems caused by the high blood sugar. Doctors will look for the cause of the high blood sugar. The cause can vary from an infection to not taking your medicine properly. Severe hyperglycemia usually happens if:

  • You have not yet been diagnosed with type 1 diabetes.  
  • Your diabetes is poorly controlled–that is, you are not keeping your blood sugar in the recommended range  
  • You have another medical problem, such as an infection, as well as diabetes.  

How long will the effects last?

How long hyperglycemia lasts depends on why it happened and how well you follow the directions for controlling it.

Type 1 diabetes is a lifelong condition. Its symptoms depend on how well you are able to control your blood sugar level.  

If you have type 2 diabetes, you will need to be careful about your diet and get enough exercise. You may need to take medicine to keep your blood sugar normal for the rest of your life.  

High blood sugar can be serious if it’s not treated. If your blood sugar runs too high over time, it can cause problems with your, eyes, kidneys, nerves, and circulation (blood vessels). A very high blood sugar can cause life-threatening problems, coma, or death. If you have type 1 diabetes, untreated high blood sugar can result in a dangerous complication called ketoacidosis (a buildup of acids in your blood). This is life-threatening but it is preventable. It usually happens only if you have type 1 diabetes. Check your urine for these acids, called ketones, when your blood sugar is high (if your provider recommends it). If there are ketones in your urine, let your provider know right away because ketones are a warning sign that your diabetes is out of control. This problem needs emergency treatment at the hospital.

Hyperglycemia caused by medicines you are taking usually goes away when you stop taking the medicine.

How can I take care of myself?

You should make sure you understand why your blood sugar is high. Follow your Reddy Urgent Care healthcare provider’s directions carefully to keep your blood sugar normal. This usually means you need to:

  • Eat a healthy diet as recommended by your healthcare provider.  
  • Exercise according to your provider’s recommendation most days of the week.  
  • Take medicine exactly as directed, if any has been prescribed.  
  • Check your blood sugar as often as your provider recommends.  
  • Not keeping your blood sugar at normal levels can cause very serious problems. It increases your risk of heart and blood vessel disease, stroke, kidney problems, and loss of vision.

If you have diabetes, talk to your healthcare provider and ask:

  • When do I need to call you about a high blood sugar level?  
  • How should I take care of myself if I’m sick and my blood sugar is going up?  
  • What can I do to prevent high blood sugar?

If you don’t have diabetes but there are others in your family who have high blood sugar or type 2 diabetes, you should:

  • Have your blood sugar checked at least once a year. 
  • Keep a healthy weight for your height and age.  
  • Exercise regularly according to your healthcare provider’s recommendation.  

If you have fasting blood sugar levels in the prediabetes range, that is, 100 to 125 mg/dL–your level of blood sugar can go back to normal with a healthy diet and regular exercise. This will help you avoid type 2 diabetes. But the potential for developing type 2 diabetes is always there.

If you do have diabetes, follow your healthcare provider’s recommendations for:

  • eating healthy  
  • getting physical activity  
  • taking your medicines to keep your blood sugar normal  
  • keeping your checkup appointments.
