Metformin Overview

Metformin, also known as Glucophage, is a widely used medication for managing type 2 diabetes. It belongs to the class of drugs called biguanides, which work by decreasing glucose production in the liver and improving insulin sensitivity in the body.

Metformin is considered a first-line treatment for type 2 diabetes and is often prescribed in combination with lifestyle changes such as diet and exercise. It helps lower blood sugar levels, reduce the risk of complications associated with diabetes, and improve overall metabolic health.

It is important to follow the prescribed dosage and recommendations provided by your healthcare provider while taking Metformin to ensure its effectiveness and minimize the risk of side effects.


Gastric bypass patients can benefit from using Metformin as it helps to control blood sugar levels.

Metformin can also aid in weight loss for gastric bypass patients by improving insulin sensitivity and reducing appetite.

Additionally, Metformin may reduce the risk of heart disease and improve overall cardiovascular health in gastric bypass patients.

Using Metformin after gastric bypass surgery can help patients maintain a healthier lifestyle and manage their diabetes more effectively.

Metformin Absorption

Metformin Absorption

After gastric bypass surgery, the stomach is made smaller, and the intestine is rearranged. This can affect the way metformin is absorbed in the body. Gastric bypass patients may experience changes in the way their body responds to the medication, leading to fluctuations in blood sugar levels.

It is crucial for gastric bypass patients to work closely with their healthcare providers to monitor their blood sugar levels and adjust their metformin dosage as needed. This ensures that the medication remains effective in managing diabetes post-surgery.

Additionally, gastric bypass patients should follow a strict diet and exercise regimen to complement the effects of metformin and maintain healthy blood sugar levels. Consulting with a healthcare provider or a nutritionist can help create a tailored plan for success.


Metformin is typically taken orally with a meal to reduce stomach upset. The dosage varies depending on the individual and the specific condition being treated. It is important to follow your healthcare provider’s instructions carefully when taking metformin.

Important guidelines for usage:

1. Take metformin exactly as prescribed by your healthcare provider.

2. Do not crush, chew, or break the extended-release tablets. Swallow them whole.

3. Metformin is usually taken once or twice a day with meals. Follow the schedule provided by your doctor.

4. If you miss a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule.

5. Do not exceed the recommended dosage of metformin without consulting your healthcare provider.
