Metformin

Metformin

Metformin controls high blood sugar levels caused by diabetes mellitus or type 2 diabetes. In type 2 diabetes, the body's insulin has not reached the cells that carry out essential metabolic functions.

Most people manage their diabetes with diet and meal plans provided by doctors. But for those with high blood sugar levels, using Metformin with insulin might help control diabetes.

What are the uses of Metformin?

Metformin is used in treating type 2 diabetes. It works by restoring your body's response to insulin. It also reduces the amount of sugar your liver makes, which your stomach or intestines absorb.

Effectively managing diabetes can help reduce the risk of kidney damage, blindness, diabetes retinopathy, masalah saraf, loss of limbs, and sexual dysfunction. In addition, heart attack or stroke-related risks might also be reduced.

How does metformin treat diabetes?

Metformin achieves blood sugar reduction through three primary mechanisms:

• Peningkatan Sensitivitas Insulin: It increases the body's responsiveness to insulin, a hormone that transports sugar from the blood to cells for energy. Metformin combats insulin resistance, where cells don't efficiently use insulin, resulting in elevated blood sugar levels.
• Reduced Sugar Absorption: Metformin curbs the absorption of sugar from the diet in the intestines, diminishing the influx of sugar into the bloodstream.
• Lowered Sugar Production: Metformin addresses the body's natural sugar production, primarily occurring in the liver. It limits the amount of sugar produced by the liver, contributing to overall blood sugar control.

How and when to use Metformin?

• Metformin can be taken orally. A doctor usually prescribes doses after evaluating your condition. Taking medicine 1-3 times a day with meals is typically prescribed. Also, drinking plenty of water with the medicine is usually advised.
• The dosage depends on the medical condition, other medication, and response to those medications and treatments. Always discuss with the doctor all the medicines you currently have - herbal, prescription, or non-prescription. Also, a gradual dosage increment is recommended, starting with a low dosage. Make sure you take it at the same time every day.
• If you are already taking other drugs, your doctors will determine if you should continue or stop other medications. Monitor your blood sugar level regularly, as directed by the doctor, to keep track of your body's glucose. Depending on the treatment response, the doctor will adjust the dosage. You can take it in tablets, solutions, extended-release suspension, and extended-release tablet forms.

Pertanyaan Umum (FAQ)

1. What does metformin do to your body?

Metformin primarily helps regulate blood sugar levels in your body. It enhances insulin sensitivity, reduces sugar absorption from the intestines, and lowers sugar production in the liver.

2. Can I stop taking metformin if my sugar levels are normal?

You should not stop taking metformin without consulting your healthcare provider, even if your blood sugar levels are normal. Your doctor will determine the most appropriate treatment plan for your condition.

3. Is insulin better than metformin?

Insulin and metformin serve different purposes. Insulin is often used when blood sugar cannot be adequately controlled with oral medications alone. The choice between them depends on individual circumstances and the stage of diabetes.

4. What is the difference between metformin and Glimepiride?

Metformin and Glimepiride are both diabetes medications, but they work differently. Metformin reduces blood sugar by addressing insulin resistance and sugar absorption. Glimepiride stimulates the pancreas to release more insulin. The choice depends on your specific condition and treatment goals.

5. How does metformin differ from other diabetes medications?

Metformin is distinct from many other diabetes medications because it does not lead to hypoglycemia (low blood sugar) when used alone. It also offers weight-neutral or weight-reducing effects, making it suitable for people with Type 2 diabetes who are overweight. Other diabetes drugs may have different mechanisms of action and side effects. Your doctor selects the most appropriate one based on your needs.
