  1. My husband has typed diabetes and we don’t know how to check his blood sugar levels is there a machine or something I can get at the drug store he is on metformin but all he does is sleep he also is fighting cellulitis what can I do

    • If he is on metformin he has seen a doctor. Any doctor worth seeing would have explained how to check his sugar at home, and most likely sent him to a nutritionist. Many doctors and nutritionist will give you test monitors for free. Unless you are getting a your meds and diagnosis from the neighbors find another doctor.

    • Yes! Its called Accucheck! Or ANY other brand in any drugstore (CVS, Walgreens, …), Walmart. They ALL have it! Ask a pharmacist at a drugstore or Walmart. They will help you choose not very expensive one and they will explain, how to use it!

    • Evelyn, your doctor should have told him to get a glucometer to test his blood sugar and how many times a day he should test it. He will have to prick his finger and put the drop of blood on the test strip. Each meter has test strips and a meter to measure.
      If he is sleeping alot his blood sugar levels are probably high. You need to get that meter as soon as possible and start monitoring his blood sugar and make sure your doctor is telling you the information. A nutritionist should also have been prescribed.

  2. I am controlling my high sugar with diet. The past month or so I have no appetite whatsoever. I realize at 80 years this may be normal but it isn’t for me. I’ve gone from 160lbs down to 145lbs.This would be great but I have had a loosing weight battle since 1969 when my last baby was born.. Do you have any answers?

  3. In my opinion the medical community puts in a criteria they feel everyone should fall into. They have attendances not to think out of the box. My sugars Always run high in the morning. However by midday I am always in normal range. So if I take a fasting blood test the panic button gets hit. Meanwhile every 6 months my A1C average is as low as 6.0 and as high as 6.4. I’m on no medication. Diet and exercise are my regiment for well over 10 years. I recently had spinal fusion surgery and several epidural injections prior. That wreak havoc on my body shot A1C to 9.8. Took 5mg of Glyizide for a month as directed. Went to my Endocrinologist after that and she did blood Sugar test. Guess what it was 76. She got me applesauce quick. Stopped medication immediately. So moral of story is we don’t all fit in the box. Best of luck to all be careful. What’s good for me may not work for you.

    • You are correct. I was pre-diabetic (6.1) and then I had a stroke and my A1C was 6.8. I was going through a divorce. They put me on Metformin…but I started getting all sorts of yeast infections. I stopped taking the Metformin. Those infections have stopped. My A1C is controlled by diet. They just go by the norm…but everyone don’t fit the norm…

  4. I am shocked to see such good info on blood sugar and i have add the problems for 25 years i am not able to read it all right now but it look very easy to under stand thank you

  5. My bloods are a nightmare up and down all the time I am good with food I don’t drink alcohol and carnt move like I am 67 was diagnosed when was 50 a great surprise I have alot wrong with me my body is in so much pain I take morphine 2 times a day 80 mills a day my sugar are between 8 or 9 and at tea time between 10 1 up to 10 9

  6. I hurt my back and they gave me some steroids for inflammation. The steroids raised my blood A1C to 9.5 and put me in the hospital for 4 days. After my stay in the hospital, we tried metformin, but it wasn’t for me so I switched to Jardiance. I took Jardiance for about 5 months. When I went back to the doctor my A1C 5.5 back to the normal range. The doctor didn’t think I was really diabetic. He said that I am allergic to steroids and I shouldn’t take any steroid medication. When I check my blood sugar it is normally 93-99 range. I do not take Jardiance anymore. I just watch what I eat and keep a check on my blood sugar So far so good. This article is on point with the information it’s giving.
