Metformin
chemical compound

Metformin, sold under the brand name Glucophage, among others, is the main first-line medication for the treatment of type 2 diabetes, particularly in people who are overweight. It is also used in the treatment of polyendocrine metabolic ovarian syndrome, and is sometimes used as an off-label adjunct to lessen the risk of metabolic syndrome in people who take antipsychotic medication. It has been shown to inhibit inflammation, and is not associated with weight gain. Metformin is taken by mouth.
Metformin is generally well tolerated. Common adverse effects include diarrhea, nausea, and abdominal pain. It has a small risk of causing low blood sugar. High blood lactic acid level (acidosis) is a concern if the medication is used in overly large doses or prescribed to people with severe kidney problems.
Metformin is a biguanide anti-hyperglycemic agent. It works by decreasing glucose production in the liver, increasing the insulin sensitivity of body tissues, and increasing GDF15 secretion, which reduces appetite and caloric intake.

Why this record matters
“Metformin” is worth following because a concise public description often conceals a longer documentary argument. Here, Metformin, chemical and compound provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q19484. The Library of Congress control number is sh2007006278. None of the 1 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
