How to find an obesity medicine doctor: what ABOM certification means, how to verify it for free, telehealth checks, insurance and questions to ask.
Key takeaways
- ABOM certification signifies specialized knowledge in obesity medicine; more than 11,500 physicians in the U.S. and Canada held it after the October 2025 exam.[2]
- ABOM diplomates are already board certified in a primary specialty, most often internal or family medicine, and passed an extra obesity medicine exam.[1]
- You can check ABOM certification, primary board certification and state licensing for free before booking.[3]
- Medicare covers obesity counseling in primary care for people with a BMI of 30 or more, on a set visit schedule.[7]
- Ask any prescriber which exact product you would get: the FDA has received about 990 reports for compounded semaglutide and more than 730 for compounded tirzepatide.[10]
In short: An obesity medicine doctor is a physician with extra training in treating obesity as a chronic disease, using nutrition, activity, behavior support and, when appropriate, FDA-approved medication or a referral for surgery. The most common credential in the U.S. is certification by the American Board of Obesity Medicine (ABOM), which you can verify for free on its website. This guide explains what that credential means, how to check it, how to find one in person or by telehealth, and what to ask at a first visit (checked on October 6, 2026).

What obesity medicine is
Obesity medicine treats obesity as a long-term medical condition rather than a matter of willpower. A physician in this field looks at the causes and effects of weight in the whole person: other conditions such as type 2 diabetes, high blood pressure, sleep apnea or fatty liver; medicines that can raise weight; sleep, stress and mood; and eating and activity patterns. Treatment usually combines a structured lifestyle program with follow-up, and may add one of the FDA-approved weight-management medicines or a referral to a bariatric surgery program. Our medical weight loss hub describes what that care usually includes.
You do not have to see a specialist to get good weight care. Primary care physicians, nurse practitioners and physician assistants also screen, counsel and prescribe. A specialist can help most when weight is complex: several related conditions, many medicines, past treatments that did not help, or questions about combining medicine and surgery.
What ABOM certification means
The American Board of Obesity Medicine describes certification as signifying “specialized knowledge in the practice of obesity medicine” and says it distinguishes a physician as having achieved competency in obesity care. Certified physicians are called diplomates. ABOM lists two routes to the exam, both of which require an active medical license, a completed residency in the U.S. or Canada and active certification by a primary specialty board (an ABMS member board or the osteopathic equivalent):
- Continuing medical education route: for practicing physicians who complete the required obesity-specific education.
- Fellowship route: for physicians who complete an obesity medicine fellowship recognized by the Obesity Medicine Fellowship Council, within 36 months before applying.
The exam is given once a year at testing centers, and ABOM offers recertification through either a journal-article review pathway or a repeat exam. In plain terms: an ABOM diplomate is already a board-certified physician in another specialty who has passed an additional obesity medicine exam.
Who becomes an obesity medicine doctor
Obesity medicine physicians come from many primary specialties. Among the 2,000 physicians newly certified in October 2025, most were internists or family physicians, and ABOM noted that nearly 70% said they had been practicing obesity medicine for less than two years. That matters when you choose: an endocrinologist or a pediatrician with ABOM certification brings a different background than a surgeon or psychiatrist with the same credential.
| Item | Value |
|---|---|
| Internal medicine | 39% |
| Family medicine | 30% |
| Pediatrics and pediatric subspecialties | 7% |
| Surgery | 5% |
| OB-GYN, psychiatry and endocrinology (3% each) | 9% |
| Other specialties | 10% |
Other specialties = the remainder after the groups ABOM listed.

How to verify a doctor, step by step
Five checks before you book (all free)
- ABOM diplomate?Search the ABOM certification verification page by name and location.
- Primary board?Confirm the doctor's main specialty certification with that board or with ABMS Certification Matters.
- Active license?Check your state medical board's license lookup, or the Federation of State Medical Boards' DocInfo.
- Licensed in your state?For telehealth too, confirm the clinician holds a license in your state.
- In network?Ask your insurer whether the doctor and the clinic are in network and whether a referral is required.
The official tools (checked on 2026-10-06): the ABOM certification verification search; the Obesity Medicine Association’s provider directory, which lists its member clinicians; ABMS Certification Matters for primary board certification; and the Federation of State Medical Boards’ DocInfo, which gathers license and disciplinary information from state medical boards. A society directory shows membership, not certification, so check both when it matters to you.
In person or by telehealth
Both can work. In-person care makes it easier to take measurements, do a physical exam and order labs on the same day. Telehealth can be convenient and may be the only nearby option in some areas, but it should still include a real medical history, a review of every medicine, lab tests when needed and planned follow-up. Ask whether the service prescribes FDA-approved brand products or compounded drugs: the FDA says compounded drugs are not FDA approved and are not reviewed for safety, effectiveness or quality, and it has received hundreds of adverse-event reports linked to compounded semaglutide and tirzepatide. Our guides to telehealth weight loss and compounded GLP-1s explain what to check.
What a first visit usually includes
According to the NIH’s National Heart, Lung, and Blood Institute, clinicians assess weight with BMI and waist size, review medical history and do a physical exam; a waist above 40 inches in men or 35 inches in women is linked to higher health risk. Expect questions about your weight over the years, eating, activity, sleep, stress and mood, and about every medicine and supplement you take. The clinician may also order blood tests to look for conditions linked to weight. A good first visit ends with a plan you understand, including when you will be seen again.
- Bring: a list of all medicines and supplements with doses, recent lab results, a short weight history (what changed, what you tried) and your goals in your own words.
- Know your numbers: our BMI calculator and waist-to-height calculator help you prepare; they are starting points, not a diagnosis.
- Bring a companion if it helps, and say if past conversations about weight were hard for you. Respectful care is part of good care.
Insurance and cost
Medicare covers intensive behavioral therapy for obesity for people with a BMI of 30 or more when a primary care clinician provides it in a primary care setting: weekly visits in the first month, every other week in months 2 to 6, and monthly in months 7 to 12 for people who lost at least 3 kg (about 6.6 lb) in the first six months. HealthCare.gov lists obesity screening and counseling among the preventive services Marketplace plans must cover without a copay from an in-network provider. Specialist visits, labs and medicines follow your plan’s usual rules, and many plans ask for prior authorization for weight medicines. Our insurance hub and GLP-1 coverage guide walk through the questions to ask.
Questions to ask an obesity medicine doctor
- Are you certified by the American Board of Obesity Medicine, and what is your primary specialty?
- Which treatments do you offer, and how do you decide what fits a patient?
- Do you work with registered dietitians, behavioral health professionals and surgeons?
- If you prescribe medicine, will it be an FDA-approved brand product, and how will we monitor side effects?
- How often will we meet, and what will each visit and each test cost with my plan?
- What is the plan for keeping weight off, and what happens if I stop a medicine?
Red flags
- Guarantees of a set number of pounds by a set date; the Federal Trade Commission lists claims like these among signs of misleading weight-loss ads.
- A prescription without any medical history, or without asking about thyroid cancer in the family, pregnancy plans or your other medicines.
- Pressure to prepay a long package before anyone has reviewed your health.
- Products labeled “for research purposes” or “not for human consumption”; the FDA warns about these sellers.
- Fat-dissolving injections offered for the belly or thighs; the FDA has approved only one, Kybella, and only for fat under the chin.
Other professionals who can help
Weight care is often a team effort. Endocrinologists help when diabetes, thyroid or hormonal conditions such as PCOS are involved; registered dietitians build eating plans, including on a GLP-1 medicine (see eating on a GLP-1); behavioral health professionals help with emotional eating and body image (see body image during weight loss); and bariatric surgeons offer surgery (see find a bariatric surgeon). The find a provider hub explains which professional does what.

Frequently asked questions
What is an obesity medicine doctor?
A physician with extra training in treating obesity as a chronic disease, using nutrition, activity, behavior support and, when appropriate, medication or a referral for surgery. In the U.S., certification by the American Board of Obesity Medicine (ABOM) is the most common credential.
How do I know if a doctor is board certified in obesity medicine?
Search the doctor's name on ABOM's free certification verification page. Also confirm their primary board certification and an active state license.
How many obesity medicine doctors are there?
ABOM reported that more than 11,500 physicians in the U.S. and Canada were certified after its October 2025 exam, when 2,000 physicians passed.
Do I need a referral to see an obesity medicine specialist?
It depends on your plan. Many HMOs require a referral from your primary care doctor before a specialist visit; ask your insurer before booking.
Is an endocrinologist the same as an obesity medicine doctor?
No. An endocrinologist specializes in hormones and conditions such as diabetes and thyroid disease. Some endocrinologists are also ABOM certified, but in 2025 only about 3% of new ABOM diplomates were endocrinologists.
Can an obesity medicine doctor prescribe Wegovy or Zepbound?
Any licensed prescriber can prescribe them when they judge it appropriate after an evaluation. An obesity medicine doctor may have more experience choosing and monitoring these medicines and combining them with other care.
Are telehealth obesity doctors legitimate?
Many are. Check that the clinician is licensed in your state, that you get a real medical review and follow-up, and whether you would receive an FDA-approved brand product or a compounded drug.
Does Medicare cover visits for weight?
Medicare covers intensive behavioral therapy for obesity for people with a BMI of 30 or more in primary care: weekly visits in month 1, every other week in months 2 to 6, and monthly in months 7 to 12 if at least 3 kg was lost.
Does InstaTuck list or recommend obesity doctors?
Not on this page. We explain how to check credentials using official tools. Any future directory will show where each credential was checked and when, and paid listings would always be labeled.
