Will I need to test my blood glucose with a glucometer while I'm taking metformin? If you are taking metformin alone, and your diabetes is stable, you will probably not need to test your blood glucose with a glucometer. But it is important to check your HbA1c every 3–6 months.
The good news: “A patient with well-controlled type 2 diabetes who's treated with metformin (an oral medication) may only check their glucose a few times a week or month,” says Dr. Kohlenberg. (If you have type 1 diabetes and administer multiple insulin injections each day, you'll need more frequent monitoring.)
To work properly, the amount of metformin you take must be balanced against the amount and type of food you eat and the amount of exercise you do. If you change your diet or exercise, you will want to test your blood sugar to find out if it is too low.
Monitoring for any oral antidiabetic agent includes fasting blood glucose, postprandial blood glucose, and hemoglobin A1C (HbA1c) every 3 to 6 months.
Most people with type 2 diabetes only need to check their blood sugar once or twice a day. If your blood sugar level is under control, you may only need to check it a few times a week. You may test yourself when you wake up, before meals, and at bedtime.
Target blood sugar levels differ for everyone, but generally speaking: if you monitor yourself at home – a normal target is 4-7mmol/l before eating and under 8.5-9mmol/l two hours after a meal.
What should your blood sugar be when you wake up? Whenever possible, aim to keep your glucose levels in range between 70 and 130 mg/dL in the morning before you eat breakfast, and between 70 and 180 mg/dL at other times.
I learned – as millions of people with type 2 diabetes have – that metformin doesn't immediately lower your blood sugar. It can take four or five days to experience the full benefit, depending on your dosage.
How long to take it for. Treatment for diabetes is usually for life. But if your kidneys are not working properly, your doctor will tell you to stop taking metformin and switch you to a different medicine.
Sudden, unexplained increases in blood sugar that persist for several days may be a sign that your metformin is no longer working. Speak with your healthcare provider about whether your dose needs to be increased or if other diabetes medications are needed.
Metformin does not usually cause low blood sugar (known as hypoglycaemia, or "hypos") when taken on its own. But hypos can happen when you take metformin with other diabetes medicines, such as insulin or gliclazide. Early warning signs of low blood sugar include: feeling hungry.
As much as possible, avoid white bread, white rice, white pasta, candy, soda, desserts, and snacks like chips or crackers. Eating foods that can spike your blood sugar will not necessarily make the metformin not work, however, it will increase the burden it has to work against.
Metformin is very effective at controlling blood glucose and lowers A1c levels by as much as 1.5% at maximum doses. By itself, metformin does not usually cause low blood glucose. Side effects including diarrhea. However, a slow increase in doses or extended release preparations can often prevent this.
The dawn phenomenon is an early-morning rise in blood sugar, also called blood glucose, in people with diabetes. The dawn phenomenon leads to high levels of blood sugar, a condition called hyperglycemia. It usually happens between 4 a.m. and 8 a.m.
If your blood sugar level is slightly high for a short time, emergency treatment won't be necessary. But if it continues to rise you may need to act fast to avoid developing diabetic ketoacidosis (DKA). If your blood sugar level is 15 mmol/l or more, you should check your blood or urine for ketones.
As the medication helps your body reduce your overall blood sugar levels and restore your ability to respond to insulin, you'll not only feel better, but you may reduce the risk of future complications of high blood sugar, such as heart disease, kidney damage, nerve damage or diabetic neuropathy, and eye damage ( ...
Metformin may have an adverse effect on renal function in patients with type 2 DM and moderate CKD.
If your blood sugar is high despite medication, it could mean a few things: Your dosage is not high enough, you are not responding to the medication as expected, or your diet, exercise, and lifestyle are not helping enough to control your blood sugar.
Metformin reaches the highest concentration in the blood (peak concentration) 1-3 hours after taking the pill. The half-life of metformin is 2-6 hours. Half-life of a drug is the time it takes for the concentration of a drug to be reduced by 50%. However, the half-life may take up to 14 hours.
If HbA1c is more than 48 mmol/mol or fasting blood glucose is more than 11 mmol/L, your blood sugar is high. For most people without diabetes, normal blood sugar levels are: between 4 and to 6 mmol/L before meals. less than 8 mmol/L two hours after eating.
In general: Less than 100 mg/dL (5.6 mmol/L ) is normal. 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes. 126 mg/dL (7.0 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
Normal blood sugar levels when you wake up
According to the American Diabetes Association, your blood sugar when you wake should be below 100 mg/dL (5.6 mmol/L) if you don't have diabetes.
