why metaformin? I'm trying to figure this out?

"Although clinical trial data are lacking to support or refute the use of off-label metformin in addition to insulin for type 1 diabetes, some patients with type 1 diabetes may benefit from the addition of metformin to their ongoing insulin regimen. The patients in whom it would make the most clinical sense to consider this are those who are overweight, require large doses of insulin, and/or continue to have uncontrolled A1c values despite adherence to insulin. Patients should be made aware that hypoglycemia may become more likely once metformin is added to their insulin regimen."

I Googled "Is Metformin used in Type 1 Diabetes cases"

Also is it possible she may be prediabetic perhaps?

I am not a doc - just recently diagnosed wth Type 2

Stop lying to yourself. You are nowhere CLOSE to being a doctor. In fact, your ignorance about Diabetes is DANGEROUS to your grandmother, if for no other reason than your ignorance prevents her from seeing and listening to a GOOD doctor.

There are TWO types of Diabetes, Type 1 and Type 2. EACH HAS A DIFFERENT CAUSE, and thus each has different treatments.

Type 1 Diabetes is caused when your pancreas fails. The pancreas produces insulin, and when the pancreas fails it does not produce insulin. When this happens the ONLY TREATMENT possible is Insulin Injections.

Insulin MUST be injected. Insulin CANNOT be taken orally -- the acids in your stomach destroy it. Taking insulin by mouth is completely and utterly useless.

Metformin (glucophage) IS NOT INSULIN. Metformin is an ORAL medication, but insulin cannot be taken by mouth.

Type 2 Diabetes is caused by being overweight. In this case there are TWO problems:

(1) The pancreas is still working, but it can nor produce enough insulin to handle the overweight body.

(2) Being overweight causes the body to fail to use the insulin it has. This is called Insulin Resistance.

There are several types of Oral Medications for Diabetes, of which Metformin is the most commonly prescribed. It reduces the amount of sugar excreted by the liver into the blood, thus reducing blood sugar. Because there is less sugar in the blood, Metformin also offers a SMALL amount of weight loss. This class of drugs IS NOT recommended for Type 1 Diabetics.

Another class of medications are those than cause the pancreas to work harder. These drugs "squeeze" more insulin out of the pancreas, thus reducing blood sugar. This class of drugs IS NOT recommended for Type 1 Diabetics.

Another class of drug is used to make the body more sensitive to insulin. These are often recommended when Insulin Resistance is suspected. This class of drugs IS NOT recommended for Type 1 Diabetics.

Of course, Insulin injections ALSO work for Type 2 Diabetes. Insulin injections work the fastest, and can bring blood sugar down with 15-30 minutes. ALL Oral Medications can take 3-4 hours to have an effect

But the point is, THERE IS NO SUCH THING AS "ORAL INSULIN". Insulin cannot be taken by mouth. Any Diets medication that is taken by mouth IS NOT INSULIN.

SO, there are questions.

(1) If your grandmother TRULY is a Type 1 Diabetic, why is she not taking insulin injections? THERE IS NO ORAL INSULIN, and insulin is THE ONLY medication that can be used for Type 1 Diabetes.

(2) If your grandmother is TRULY a Type 1 Diabetic then she is being mistreated. But, if she is not taking insulin but is taking oral medications, and is still alive, is she truly a TYPE 2 Diabetic?

(3) YOU said she has trouble keeping her blood sugar UP. That IS NOT a sign of Diabetes. Diabetes is defined as "consistently HIGH blood sugar". Low blood sugar is a sign of Hypoglycemia, the OPPOSITE of Diabetes.

HOWEVER . . . a diabetic who is under treatment, but is NOT following a properly nutritious diet will have Hypoglycemic Attacks if they don’t eat ENOUGH food while taking the medication.

(4) IS your grandmother following a properly designed Diabetic Diet, and eating the proper meal size and carbohydrate content, AND eating her meal at the proper time everyday? Or is she believing that the less she east the "better" she will feel? THIS IS INCORRECT, and potentially fatal. Diabetics MUST EAT THE PROPER DIET, including the proper serving sizes.

It is VERY common for Diabetic patients, ESPECIALLY THE ELDERLY, to not eat proper diets, and therefore suffer from Hypoglycemic attacks.

BOTH you and your grandmother need a great deal of education. SHE probably knows little to nothing about the disease, and YOU fool yourself by thinking you are educated enough to help.

ASK HER DOCTOR to recommend YOU BOTH to Diabetic classes that are offered by a local hospital. You BOTH need to learn the difference between Type 1 and Type 2 Diabetes, the different treatments that are used for each one, AND the necessity of properly following doctor's orders concerning the EXACT diagnosis (Type 1 or Type 2) WHAT medication to take, the proper dosage, AND the proper meal size and schedule.

Don’t fool yourself -- YOUR medical knowledge falls FAR short of what is necessary to help your grandmother. In fact, your misguided ideas could actually lead to her death!

YOU NEED EDUCATION!! Ask her doctor to make the necessary recommendations for YOUR education.

I've not had an appointment with one but I did used to work for one. They will ask you about your medical history and your partners and they will give you a full examination inside and out. They will probably book you for an ultrasound and possible a hysterosalpingram before going in for a laparoscopy but it will depend on what the ultrasound shows.
