Metformin: What It Does, What to Expect, and Whether It Might Be Right for You

Metformin is FDA-approved to treat Type 2 diabetes. It works by reducing the amount of glucose your liver releases into the bloodstream and improving how your body responds to insulin. It doesn't cause your pancreas to produce more insulin, which is part of why it carries a low risk of hypoglycemia on its own.

Beyond diabetes, doctors have used metformin off-label for years to help with weight management, polycystic ovary syndrome (PCOS), and metabolic conditions that involve insulin resistance. The research supporting these uses has grown steadily, and it's now a routine part of how many physicians approach metabolic health.

If you're not sure whether metformin makes sense for your situation, that's exactly the kind of question a primary care visit is for. There's no need to arrive with a diagnosis already in hand.

1. 1

   What the evidence says

   Studies have shown average weight loss of 2 to 5 kilograms over several months with metformin, with better results when combined with dietary changes. It's not dramatic, but it's real, and for patients who can't access or afford GLP-1 medications like Mounjaro or Wegovy, it represents a legitimate, evidence-based starting point.

2. 2

   Who tends to benefit most

   Patients with insulin resistance, elevated fasting glucose, or PCOS often see the most meaningful response. Metformin helps the body use insulin more efficiently, which can reduce fat storage and curb appetite in some people. It works differently for different people, which is why having a doctor track your response matters.

3. 3

   Metformin vs. GLP-1 medications

   If you've been reading about Ozempic or Wegovy and wondering whether metformin is a comparable option, the honest answer is: they work differently. GLP-1 medications tend to produce more significant weight loss and have additional cardiovascular and metabolic benefits. Metformin is less expensive, has a longer track record, and works well for certain patients. Sometimes they're used together. The right choice depends on your health history, your goals, and what's actually accessible to you.

   Results and the sealed envelope

   When lab results are back, Dr. Gougian completes and signs the I-693 and seals it in an envelope for USCIS. With complete records and normal labs, that is often within a few days of your visit. If a vaccine dose or repeat test is needed, we give you a realistic date before you leave. Don’t open the sealed envelope; you receive a separate copy to keep.

5. 5

   If something turns up

   A positive tuberculosis blood test, for example, usually means a chest X-ray, not a denial. We explain what it means, arrange what is needed, and complete the form when it is done. You are never left guessing.

We know the timeline matters. Many patients are working against an interview date or a request for evidence, and we schedule and process exams with that in mind. The exam is a flat fee quoted before you book; blood tests and vaccines are itemized and added only if you need them, so there are no surprise costs.

This is what most people search for first, and for good reason. Metformin does cause side effects in some patients, and it's worth knowing what to expect before you start.

Gastrointestinal symptoms are the most common. Nausea, diarrhea, stomach cramping, and a general feeling of digestive upset affect a meaningful portion of people who start metformin, especially in the first few weeks. This is the main reason people stop taking it. But it's also very often preventable.

Taking metformin with food helps significantly. Starting at a low dose and increasing gradually also reduces the likelihood of GI symptoms. Extended-release metformin (metformin ER) tends to be better tolerated than the immediate-release version for people who are sensitive. These are adjustments your doctor can make from the start, rather than waiting for you to have a bad experience.

Pandora Family Medicine is a neighborhood practice at 6300 Baltimore Ave in University Park, MD. Dr. Gougian prescribes metformin as part of diabetes management, weight loss care, and treatment for conditions like PCOS. She sees the same patients over time, which means she's not making a one-time decision based on a single visit.

If you're coming in specifically about weight loss, the initial visit is $200 and follow-up visits are $150. There's no subscription, no required program, and no monthly fee. You pay for the visit. If metformin is appropriate, she'll write the prescription. If something else makes more sense, she'll say so.

Questions about metformin come in a few predictable shapes. Here are honest answers to the ones we hear most often.

Patients come from across the region because there are not many Civil Surgeons who do this volume of exams, and fewer still who do them in Spanish. We regularly see patients from Hyattsville, College Park, Langley Park, Takoma Park, Silver Spring, Riverdale Park, Greenbelt, Laurel, and Washington, DC.
