What is metformin, and what is it used for in Europe?

Metformin explained: type 2 diabetes treatment, insulin resistance, HbA1c reduction, polycystic ovary syndrome (PCOS), and prescribing criteria.

In this episode, we outline how metformin works and how doctors prescribe and monitor it under EU medical guidance.

You’ll learn:

• What metformin is (a first-line oral medication for type 2 diabetes)

• How it reduces hepatic glucose production

• Why it improves insulin sensitivity

• Common uses beyond diabetes, including PCOS

• Typical side effects: nausea, diarrhoea, abdominal discomfort

• The rare risk of lactic acidosis

• Monitoring requirements: kidney function (eGFR), HbA1c, vitamin B12 levels

• Situations where treatment may be declined or adjusted (renal impairment, acute illness)

We explain how doctors assess blood glucose levels, HbA1c, kidney function, BMI, cardiovascular risk, and medication history during an online consultation in the EU. Metformin is prescribed based on confirmed metabolic indications and requires periodic laboratory monitoring.

This episode reflects the clinical standards used by Mobi Doctor, where metabolic consultations are reviewed by a registered physician in line with EU prescribing guidance.
