Q & A: How To Lower Your Blood Sugar When It's Over 200 mg/dl

Nov 20, 2009

Q: How do I lower my blood sugar when it goes over 200 mg/dl? I have  type 2 diabetes.

A: An excellent question, but a complicated one to answer. Your doctor or nurse educator should be contacted whenever your blood sugar runs consistently higher than 250 mg/dl for more than two days. When a person with type 2 diabetes encounters a high blood sugar, the strategy used to bring it down will vary from individual to individual. This is because of differences in treatment involving diet, exercise, and medication. It will also depend upon the guidelines for glucose control that you and your doctor have mutually agreed upon.

When high blood sugars do occur, there are a number of strategies that can be employed to lower the glucose level back down to a normal range. These might include:

1) Eating less food at the next meal, eliminating a snack, and/or eating foods with a lower glycemic index.

A general rule of thumb to follow is to eliminate 15 grams of carbohydrate (the amount in one starch exchange, one fruit exchange, or one cup of skim milk exchange), which will lower blood glucose by 30 mg/dl. If you test your blood sugar at 182 mg/dl before a meal or snack, then eliminate one starch and one cup of milk at the next meal to bring the glucose value close to 120 mg/dl as a baseline. Although people with diabetes will respond differently to this adjustment, it provides a basic guideline to start with.

For persons with type 2 diabetes who are overweight, the loss of only five to 10 percent of total weight can dramatically improve blood glucose values. Consequently, just cutting calories moderately can achieve better blood glucose control.

Lastly, choosing foods with a lower glycemic index, that is, foods that do not raise blood sugar as quickly or dramatically, can help to bring blood glucose back into a normal range. Some examples of foods with a low glycemic index are dried beans and lentils.

To test the glycemic effect of a food on your system, you will need to do more frequent monitoring. For example, you may want to compare the effect of brown rice versus baked potato by eating equivalent carbohydrate amounts of these foods at dinner and comparing your blood glucose response two hours later. The exact effect will vary from person to person.

2) Increasing activity or incorporating more exercise.

Persons with type 2 diabetes generally respond to increased exercise with a lowered blood glucose value. Simple exercise, such as walking 20 minutes or more per day, can effectively improve glucose tolerance and induce weight loss. Proper exercise can actually be effective enough to lower or completely eliminate the need for medication altogether.

3) Increasing medications, changing medications, and/or administering them more frequently.

Although this is certainly an option, it makes more sense to first address the problem of elevated blood glucose by exercise and cutting back on food. These measures are less costly and have fewer side effects. If they aren't effective, however, a medication change may be indicated. If you are on the minimal dose of oral agents, your doctor might raise the dose or split it into morning and evening doses.

This could also be true for those using insulin. Taking more shots per day does not mean that your diabetes is worse. It may even bring more flexibility into your lifestyle. In fact, a rule of thumb for those on insulin (check with your doctor first before making these adjustments) is to take one unit of regular insulin to lower blood glucose 30 mg/dl. If your blood sugar is 191 mg/dl before a meal, an extra three units of insulin will bring the glucose down about 100 mg/dl.

It is important to note that this rule may change for people who exercise regularly because it will take less insulin to achieve the desired effect. It may also change for those who become ill  because they are more insulin-resistant and may need more insulin to achieve the desired effect. The effectiveness of insulin is also dramatically decreased by high blood sugar levels.

4) Using relaxation techniques and behavioral management.

Relaxation exercises, including deep breathing and audio tapes that guide you through deep muscle relaxation, can reduce stress and help you deal more effectively with it. Tapes are available specifically designed to create images of healthiness in diabetic individuals and encourage visualization of improved glucose control. Behavioral management techniques also increase one's overall sense of control over life and self-efficacy, so that diabetes becomes a state of "wellness in the midst of illness." When you are relaxed and in control, your blood glucose values can improve.

5) Treating identified illness and/or infections.

Illness and infection causes a rise in adrenergic hormones, which increase the production of glucose in the body. This extra surge of glucose is part of the healing process, but can upset glucose control. Thus, continuing to take medications despite poor appetite is vital. You may temporarily require more medication during periods of extended illness. Ask your doctor for instructions on dealing with illness.

6) Monitoring on a more frequent basis and/or monitoring other parameters.

When your blood glucose values exceed the target ranges established by you and your doctor, monitoring should be done every two hours until your blood glucose returns to normal. This gives you an opportunity to treat and adjust blood glucose as soon as possible, rather than waiting until your next doctor visit or next meal (which might be four or five hours later). It also tells you whether or not what you are doing is helping to bring the blood glucose down. Another step to take if your blood sugar is over 250 mg/dl would be ketone checks (done by urine dip stick or via a fingerstick to measure betahydroxybutyrate, an acid). Testing ketones hourly until they disappear is recommended.

7) Increasing consumption of sugar-free fluids.

Often, poor hydration accounts for the concentration of sugar in the blood. All people (with diabetes or not) should drink two to three quarts of sugar-free fluids per day. When glucose is elevated, drinking helps to dilute it. Also, drinking fluids is filling, decreasing the possibility of overeating.

People with heart disease who take diuretics and those with renal (kidney) complications may need to be on restricted fluids. Check with your doctor and/or dietitian if you fall into these special categories.

To combat high blood sugars, the most important strategy is prevention. Prevention of high blood sugars is usually possible with frequent and consistent monitoring. If you have awareness of your usual glucose response patterns to foods and exercise, it will be easier to plan out your day and prevent fluctuations in your blood sugar.

A very good article pulling everything together.

Posted by JudithSwartz on 22 November 2009

As a caregive for my husband recovering from a devestating stroke (summer 2008), I beg you to follow the advice and information above. Listen to your doctor and avoid a stroke, or worse. After years of trying to learn healthy eating, I found it finally in the Diabetes Food Pyramaid. Bob's blood sugar was 598 when his stroke occurred (and we suspect a heart attack at the same time). He's now off of insulin with good numbers and we're getting closer to eliminating drugs for the Hypertension. I'm not selling anything, but I did write a short book about our story, A Stroke of Health. You can manage your Diabetes and lose weight (Bob lost 100 pounds, I lost 60)by healthy eating. I'll be happy to answer questions. Good luck.

This article implies that peak blood sugar should be kept below 250 mg/dL.

In Sept. 2007, the International Diabetes Federation (IDF) published the document “Guideline for Management of Postmeal Glucose”, which can be obtained from its website, www.idf.org. Extensive studies are cited to show that significant damage results when peak glucose exceeds 140 mg/dL.

This IDF report shows that ALL diabetics MUST keep PEAK blood glucose below 140 mg/dL, NOT 250 mg/dL, if they are to avoid diabetic complications.

The primary reason that diabetes is such a deadly disease is that most doctors recommend extremely lax guidelines for controlling diabetes, similar to those presented in this article.

The essential requirement for controlling diabetes is a low-carb diet. Ideally total daily carbs should be kept below 30 grams (about one ounce). The American Diabetes Association recommends 5 to 7 time this amount.

I have been suffering with high blood sugars for more than a year, sometimes in excess of 700. The doctors and endocrynologist that I see take it very casually. I feel that I am dying by degrees. This entire last two weeks my blood sugars have been running from 450 - 600. I am at my wits end. Nobody seems to care if I die. I follow my diet and know that there is something such as an infection. They can't find anything. Help!

Posted by IrishLass4855 on 22 January 2010

for over a year my blood sugars have been in excess of 700,usually from about 538 to 700. My endocrinologist and primary care physician slap me in the hospital, get my blood sugar down to 200, send me back home and it immediately begins to escalate. Any novice know that there is an infection in my body. Yet they seem so unconcerned and I am dying day by day, fatigue, terrible pain. I have fibromyalgia. I was recently on a morphine based opiate. My medication along with money was stolen out of my doctors office. He refused to write for anymore Avinza. I have gone through hell for almost two weeks with withdrawal, pain, no sleep, awful. I will never again take a morphine based sulfate. Can anyone give me a suggestion as to how I can make my health care providers pay any attentioon? I cannot go on like this. I am to the point that I could blow my brains out.

An internist running a hospital diabetic study told me that a quick way to lower a spiked or high BS is to down water; lots of it. The idea is to dilute your blood concentration. It works for me.
