The increasing prevalence of obesity among women in the United States highlights the need for comprehensive weight management strategies within women's healthcare. Given the unique challenges women face throughout their lifespan, particularly during pregnancy, postpartum, and menopause, obstetrician-gynecologists (OB/GYNs) are well-positioned to offer support and treatment for weight management. This article explores the role of OB/GYNs in addressing weight concerns, including the use of anti-obesity medications (AOMs), and outlines the importance of a holistic approach to women's health.
The Role of OB/GYNs in Women's Overall Wellness
Beyond reproductive health, OB/GYNs play a crucial role in promoting women's overall wellness. Many offer a range of services, including:
- Vaccinations: OB/GYNs can help women stay up-to-date on essential vaccinations, especially for those who rely on them as their primary care provider.
- Birth Control Counseling: They can provide personalized guidance on birth control methods based on individual circumstances, reproductive health, and family planning goals.
- Joint and Bone Health: OB/GYNs can address concerns about joint and bone health, which are particularly important as women age and experience hormonal changes.
- Weight Management Discussions: With annual check-ups, OB/GYNs can track weight history, discuss concerns, and suggest healthy weight management strategies.
- Skin Issue Evaluation: They can assess skin issues that may indicate hormonal imbalances or other underlying conditions.
- Thyroid Problem Assessment: OB/GYNs can evaluate potential thyroid problems, which can significantly impact weight management.
- Mental Health Support: They can provide initial support for mood issues, depression, or anxiety, especially those related to hormonal changes.
- Puberty Education: OB/GYNs can serve as a valuable resource for adolescent girls and their parents, offering guidance on reproductive health and bodily changes during puberty.
- Emotional Support: They can provide emotional support and coping strategies for women navigating various life transitions, from puberty to menopause.
Obesity: A Chronic Condition in Women
Obesity is a chronic, relapsing, and treatable disease affecting a significant portion of the U.S. population. It is characterized by an increase in body fat, leading to adipose tissue dysfunction and adverse health consequences. Women are disproportionately affected by obesity, with an estimated two out of five adult women in the United States classified as obese. Several factors contribute to weight gain in women, including:
- Pregnancy: Postpartum weight retention can be a significant challenge for many women.
- Polycystic Ovary Syndrome (PCOS): Women with PCOS are at higher risk of developing pre-obesity or obesity.
- Menopause: Decreased estrogen levels, reduced physical activity, and dietary changes during menopause can contribute to weight gain.
Addressing Obesity in the OB/GYN Setting
OB/GYNs are uniquely positioned to address obesity in women due to their role in providing primary care and managing reproductive health. They are increasingly encountering patients with obesity-related complications such as infertility, high-risk pregnancies, and gynecological cancers. However, the potential to treat obesity in this setting is not fully realized, with many OB/GYNs feeling pessimistic about their ability to help patients lose weight.
Overcoming Barriers to Obesity Treatment
Several barriers hinder OB/GYNs from effectively treating obesity, including:

- Perceived lack of time
- Inadequate reimbursement
- Challenges in accessing AOMs due to cost or prior authorization requirements
To overcome these barriers, it is essential to:
- Encourage routine discussions about weight: OB/GYNs should proactively initiate conversations about weight with their patients, using patient-first language and a compassionate approach.
- Provide comprehensive counseling: Patients should receive guidance on nutrition, physical activity, and behavior modification.
- Offer appropriate medical interventions: AOMs and bariatric surgery should be considered for eligible patients.
- Address medication-induced weight gain: Clinicians should be aware of medications that may contribute to weight gain and explore alternative options when possible.
- Refer to specialists when necessary: Patients with complex cases or specific needs should be referred to obesity medicine specialists or other healthcare professionals.
Anti-Obesity Medications: An Overview
AOMs can be a valuable tool in facilitating weight loss by targeting appetite regulation and metabolic processes. The FDA-approved AOMs for long-term use include:
- Orlistat: Prevents fat absorption.
- Phentermine/Topiramate ER: Suppresses appetite and increases satiety.
- Naltrexone HCl/Bupropion HCl ER: Affects brain regions involved in appetite and reward.
- Liraglutide: Mimics the action of a naturally occurring incretin hormone, promoting satiety and slowing gastric emptying.
- Semaglutide: A GLP-1 receptor agonist that promotes weight loss and reduces cardiovascular risk.
- Tirzepatide: A combined GLP-1 and GIP agonist that is highly effective in promoting weight loss.
Considerations for Prescribing AOMs
When considering AOMs, OB/GYNs should:
- Assess patient eligibility: AOMs are typically indicated for women with a BMI of 30 or greater, or a BMI of at least 27 with one or more obesity-related comorbidities.
- Evaluate potential contraindications: Certain medical conditions or medications may contraindicate the use of specific AOMs.
- Discuss potential side effects: Patients should be informed about the potential side effects of AOMs, such as nausea, diarrhea, constipation, and increased heart rate.
- Provide guidance on lifestyle modifications: AOMs should be used in conjunction with dietary changes, increased physical activity, and behavior modification.
- Monitor patient progress: Regular follow-up appointments are essential to monitor weight loss, assess side effects, and adjust treatment as needed.
The Emerging Role of GLP-1 Receptor Agonists
Glucagon-like peptide-1 (GLP-1) receptor agonists like liraglutide, semaglutide, and tirzepatide have emerged as highly effective AOMs. These medications work by:
- Increasing central satiety
- Decreasing hunger
- Slowing gastric emptying
Clinical trials have demonstrated significant weight loss with GLP-1 receptor agonists, with some patients experiencing a 15% or greater reduction in body weight. Additionally, semaglutide has been shown to reduce the risk of cardiovascular disease.

Practical Considerations for GLP-1 Agonist Use
When prescribing GLP-1 receptor agonists, clinicians should be aware of the following:
- Contraindications: Personal or family history of medullary thyroid cancer, MEN II syndrome, or hypersensitivity to the drug class.
- Risks and side effects: Pancreatitis, suicidal ideation, gallstones, nausea/vomiting, diarrhea/constipation, dyspepsia, and increased heart rate.
- Administration: Subcutaneous injections in pre-loaded syringes, with gradual dose titration.
- Cost and availability: GLP-1 agonists can be expensive and may not be covered by insurance.
- Surgical considerations: GLP-1 agonists should be held prior to surgery to reduce the risk of aspiration.
Promoting Weight Loss and Overall Health
OB/GYNs play a vital role in promoting weight loss and overall health in women. By initiating conversations about weight, providing comprehensive counseling, and offering appropriate medical interventions, they can help women achieve and maintain a healthy weight, reduce the risk of obesity-related complications, and improve their quality of life.
