What Experts Say

Metformin remains the first choice drug for type 2 diabetes in most treatment guidelines used across Pakistan, given rising diabetes rates nationally. It works mainly by reducing glucose output from the liver rather than by increasing insulin release from the pancreas.

This mechanism means it carries a low risk of causing low blood sugar when used alone, unlike sulfonylureas or insulin. Physicians often pair it with lifestyle changes such as diet and exercise before adding other diabetes medicines, and it is frequently combined with newer drug classes once control weakens.

Kidney function is checked regularly during long term use, since reduced clearance raises the risk of a rare but serious complication called lactic acidosis. Endocrinologists also watch for vitamin B12 deficiency with extended therapy, and periodic blood tests help catch this early before symptoms like fatigue or nerve tingling appear.
