What is a good blood sugar level?

Everyone has some sugar in their blood. The normal amount of sugar in the blood ranges from about 70 to about 120 in people who don't have diabetes. Blood sugar goes up after eating, but returns to the normal range in 1 or 2 hours.

A good blood sugar range for most poeple with diabetes is from about 70 to 150. This is before a meal--like before breakfast or 4 to 5 hours after your last meal. Your blood sugar should be less than 200 about 2 hours after your last meal.

The picture below shows what ranges of blood sugar are good, too low, and too high.

Remember: Everyone is different. A good blood sugar range for someone else may not be the best for you. For example, a blood sugar of 80 may be too low for some people. Ask you doctor what the best range of blood sugar is for you.

Diabetes and hot weather

If you have diabetes, you need to take extra care in hot weather. Temperatures of 80°F (about 27°C) or above, especially with humidity, can affect medication, testing supplies, and your health.

If you have diabetes, it is harder for your body to handle high heat and humidity. The heat index, which measures how hot it really feels by combining temperature and humidity readings, advises caution starting at 80°F with 40% humidity. 

Here are suggestions from CDC’s Division of Diabetes Translation on taking care of yourself during hot weather:

Heat can affect your blood glucose (sugar) levels and also increase the absorption of some fast-acting insulin, meaning you will need to test your blood glucose more often and perhaps adjust your intake of insulin, food and liquids.

Drink plenty of fluids, especially water, to avoid dehydration. Avoid sugar-sweetened beverages such as sweet tea and sodas.

If your doctor has limited how much liquid you can drink, ask what to do during times of high heat.

Check package inserts with medications to learn when high temperatures can affect them. Take medications with you if you will need to take them while you’re away from home, and protect them from the heat.

If you’re traveling with insulin, don’t store it in direct sunlight or in a hot car. Keep it in a cooler, but do not place it directly on ice or on a gel pack.

Check glucose meter and test strip packages for information on use during times of high heat and humidity. Do not leave them in a hot car, by a pool, or on the beach.

Heat can damage insulin pumps and other equipment. Do not leave the disconnected pump or supplies in the direct sun.

Get physical activity in air-conditioned areas, or exercise outside early or late in the day, during cooler temperatures.

Use your air conditioner or go to air-conditioned buildings in your community. 

Tips to avoid heat stroke


Summer has arrived accompanied by some nice, warm weather this week.  While you are enjoying the outdoors, staff at Penobscot Valley Hospital would like to remind you to stay hydrated and take precautions against heat stroke and other heat-related disorders.  


Hydration is key when the temperature is soaring. When temperatures are high, the American Red Cross advises people to drink fluids periodically regardless of thirst, wear light-colored and loose-fitting clothes and take frequent breaks by stepping inside every so often. Check in on people who are alone and use a buddy system when exercising or working outside to ensure the heat doesn't deal an unnoticed, fatal blow.


Be alert for these signs of heat stress:


·         Heat cramps - signaled by muscle pain or spasms, usually in the legs or abdomen, that indicate the body is struggling from loss of fluids and electrolytes


·         Heat exhaustion - signaled by cool, moist, pale or flushed skin, heavy sweating, headache, nausea, dizziness, weakness or extreme fatigue  


·         Heat stroke - signaled by hot, red skin that may be dry, a change in consciousness, vomiting and high body temperature

While the elderly population is a greater risk for heat stroke, infants and children are also at risk. Never leave children or pets in a closed, hot car.  Infants, children and pets who are unattended in cars may suffer heat-related illness quickly, since the indoor temperature can rise to dangerous levels even in moderate weather. Cars should always be kept locked when not in use so that children may not enter them and become trapped. It is also important to monitor your infant’s temperature while sleeping in his/her crib.  

"Heat stroke can be life-threatening. Call 911 immediately for emergency assistance.  Move the person to a cooler place and apply cloth-wrapped ice, cold packs or wet towels to the wrists, ankles, groin, neck and armpits," says Dr. Paul Turnquist, PVH Emergency Department Physician. "As with heat exhaustion, remove or loosen tight clothing, lightly fan the person and slowly offer small amounts of water."

Tips to Prevent Lyme Disease


MAY 22 - Lyme disease is the most common vector-borne disease in Maine. Record high numbers of Lyme disease were reported in Maine during 2011. With this year’s mild winter, ticks may be active earlier so it is never too soon to start doing tick checks. Penobscot Valley Hospital would like to remind the community that May is Lyme Disease Awareness Month.


What’s important to remember about Lyme disease?

·         Lyme disease is caused by bacteria which are spread through the bite of an infected deer tick.

·         A frequent symptom of Lyme disease that sometimes appears early on is a rash. The most common appearance is a uniformly red expanding rash. 

·         Other symptoms often occur such as:

o        fatigue

o        fever

o        headache

o        joint pain

o        muscle pain or a mildly stiff neck

·         Last, but not least, Lyme disease is preventable. The best way to prevent Lyme disease is to avoid contact with the ticks that carry it.

If you are working, playing, or relaxing in areas that may have ticks you should do the following:

  • Wear light colored clothing (which make it easier to spot ticks) with long sleeve shirts and pants
  • Create an extra "no tick" zone by tucking your pants into your socks and your shirt into your pants
  • Use insect repellent (with DEET) on your skin and apply permethrin (kills ticks on contact) to your clothes.
  • Check your clothing and skin carefully after being outdoors and remove ticks promptly
  • Wash the area of any possible tick bites thoroughly with soap and water, apply an antiseptic to the area of the bite
  • Mark on a calendar the date that you were bitten, let your physician know, then watch yourself for signs of Lyme disease or any changes in your personal health every day for the next month
  • Keep your lawn mowed, cut overgrown brush, and clear away leaf litter from your home
  • Inspect pets daily and remove any ticks found

Local Lyme disease advocate Bea Szantyr, MD states, “The longer the tick is attached the greater the risk of transmission of infection. Although we often think of less than a 24-hour attachment as being safe, in fact, cases have been reported in attachments of four hours or less. Additionally, some other infectors that travel in the same ticks may be transmitted more rapidly. Prompt, proper removal is very important.”

If you have found a tick on your skin, don’t panic. Take caution to remove the tick properly.  Using fine- tipped tweezers, you should grab the tick at its mouthparts and using firm steady pressure you should pull the tick straight out. Using a tick scoop is another proven method of removal. Thoroughly cleanse the bite area and your hands with soap and water or rubbing alcohol after the tick is out. Save the tick for identification.

Do not yank or squish the tick because it may have harmful bodily fluids. Also, do not use petroleum jelly, hot matches, nail polish remover or any other substance to remove the tick. Using those items could increase the risk of an infection.

Szantyr adds, “If you have a tick bite, let your healthcare provider know, as sometimes treatment makes sense at this point. If you and your provider decide to watch and wait, pay attention to any early symptoms of tick-borne diseases which may include fever, headache, fatigue, swollen lymph nodes, or rash. See your provider if you develop one or more of these symptoms. If left untreated, infection may spread to joints, the heart, and the nervous system.”

According to the Maine Medical Center Research Institute, Lyme disease can easily and effectively be treated with oral antibiotics if diagnosed in its early stages. For more information on Lyme disease or instructions on how to properly remove a tick, visit

Prediabetes risk test available from CDC

What is prediabetes?
Having prediabetes means that your blood sugar (glucose) level is higher than normal, but not high enough to be diagnosed as diabetes. If you have prediabetes, you are more likely to develop type 2 diabetes and heart disease, and to have a stroke.
How to take the prediabetes risk test
You can take the prediabetes risk test yourself. It asks seven questions about your age, weight, physical activity, and other conditions. The test then figures out your risk level based on your answers to these questions and gives you a score. You can take the test on the Internet in by clicking here.
What to do if the risk test says you may have prediabetes
Your test score will tell you if you are likely to have prediabetes. If you get this kind of score, you should talk to your doctor or other health care provider as soon as possible about prediabetes. Your doctor or other health care provider can tell you for certain if you have prediabetes. If you do, he or she can tell you what you need to do to lower your chances of getting type 2 diabetes. These actions may include losing weight, choosing healthier foods, and increasing your physical activity.
Classes to help you prevent type 2 diabetes
If you have prediabetes, you can also find out if there are classes to help prevent type 2 diabetes near where you live. The National Diabetes Prevention Program is one program that offers such classes. Click here to find out if there are National Diabetes Prevention Program classes being offered near you.

New data can help pave the way to reduce burden


CDC’s Division of Diabetes Translation is pleased to announce the upcoming release of 2009 county-level estimates of diagnosed diabetes, obesity, and leisure-time physical inactivity in the United States. These data will be available on the Diabetes Data and Trends Web site on April 3, 2012, and add to the 2004–2008 county-level estimates already available on the Web site.

Also, for the first time, estimates of diagnosed diabetes will be available for the Puerto Rico municipios (county equivalents).

  • These data are important to help address the burden of diabetes and selected risk factors. 
  • The county-level estimates help identify counties with high estimated numbers and percentages of people diagnosed with diabetes or at high-risk of diabetes. 
  • County-level estimates diabetes and selected risk factors can be used to maximize use of existing resources for diabetes management and prevention efforts, including health policy. 
  • Combined with other resources, these data can assist in the allocation of funds to help areas hardest hit with diabetes or at high-risk of diabetes. This focused attention may help reduce rates of complications caused by diabetes and obesity, such as heart disease, stroke, and some cancers, as well as specific complications of diabetes such as kidney disease, blindness, and lower-limb amputations.
