How Blood Glucose Meters Work

Source: Web exclusive: May 2011 Using a blood glucose meter If you have diabetes, a blood glucose meter could well be your new best friend, and critical to successfully managing your disease. “A glucose meter is a tool to help know where your blood sugar is at, and what affects it,” says Karen McDermaid, a diabetes educator in Moosomin, Sask. There are lots of different models of meters’also called blood glucose monitors or glucometers’but they all work the same way: They detect the level of sugar in your blood, and give you the results almost instantly. It all comes down to chemistry Wondering how a glucose meter works? Remember high-school science class? First, you use a lancet to pierce your skin and apply a drop of blood to the meter’s test strip. Next, a series of chemical reactions takes place between the sugar in your blood and substances on the test strip, creating ferrocyanide. An electrical current flows from the ferrocyanide to the glucose meter, which uses the strength of this current to measure the amount of glucose in your blood. The meter converts it to the digital number that you record in your logbook. How not to slip up It’s possible to get an inaccura Continue reading >>

    I've been thinking a lot lately about the connection between autoimmune disorders and endocrine disorders. Recently I discovered that I have an allergy to the sun. I've never been a super outdoorsy girl because of severe allergies and a huge bug phobia and for the last ten years I've only left my house maybe 10 times a year due to various health problems. Recently I've been going out more as I lose weight and get treatment for my health problems. I'm just going to local stores so I'm getting maybe 5 minutes if direct sunlight and about 40 minutes of indirect sunlight while in the car. By the time I get home I'm covered in an itchy bumpy red rash and tiny blisters. It's not the same as a sunburn or heat rash/sweat rash. It burns and itches and I'll have a headache, muscle aches and nausea for about 24 hours. The rash goes away after about a week. I should also say that I'm a redhead with very pale skin and I do burn easily. I don't wear ANY perfume, lotion, hair products etc and none of my meds make you photosensitive. I'm just curious to know if any of you other ladies are also photosensitive. Here's a link if anyone is curious: http://www.wellness.com/reference/al...tosensitivity/

    Yes....I get really bad migraines if I'm out in the sun too long. If I'm sitting by my window with the light shining through, I feel a little tired. As soon as the sun goes down, I'll feel my energy returning. It's weird.

    I started getting sun rashes after starting metformin. I don't have fair skin, I don't burn easily, I'm not allergic to anything, and suddenly after starting on the met, I started getting this weird rash from being in the sun. It's not a sunburn, and I don't have to be sunburned for the rash to appear, but it's these bumps that look like kind of like mosquito bites that just pop up. I used to be a lifeguard, and it really freaked me out because I had been a lifeguard for 2 years beforehand, and this had never happened before. Now it just happens, no matter how much sunscreen I put on or how frequently I reapply, I always get a rash on my chest and shoulders and sometimes a few spots on my back.
