What Experts Say

Metformin is the first line medicine for type 2 diabetes worldwide. It reduces the sugar made by the liver and improves how muscles use insulin. Because it does not push the pancreas to release more insulin, low blood sugar is uncommon when it is used alone. Large trials also link it with a lower risk of heart complications in many patients.

Taking it with or right after meals reduces nausea and stomach upset. The dose is usually raised slowly over a few weeks, and regular blood sugar and HbA1c checks guide the plan. Kidney function should be checked at least once a year, and vitamin B12 now and then.

Diabetes is very common in Pakistan, so regular follow up matters. Vomiting, severe dehydration or contrast scans need a pause and a call to the doctor, because lactic acidosis is a rare but serious risk. Healthy meals and daily walking improve the effect of the tablet. Never share it with family members, since dosing depends on kidney health.
