Eating healthier and staying active can take real effort. If you are still struggling to manage your weight, you may wonder whether medical treatment could help.
Weight regulation involves appetite, hormones, genetics, sleep, medications, and more. For some adults, prescription treatment can provide additional support alongside healthy habits.
Qare prescribes GLP-1 medications for eligible adults. Here is what to know about how these medications work, who may qualify, and what treatment involves.
What are GLP-1 medications?
GLP-1 stands for glucagon-like peptide-1, a hormone involved in appetite and blood sugar regulation. GLP-1 medications act on this hormone’s receptors. They can help reduce hunger, increase feelings of fullness, and slow stomach emptying. This may make it easier to eat smaller portions and follow a nutrition plan. Semaglutide and orforglipron act on GLP-1 receptors. Tirzepatide acts on both GLP-1 and another hormone pathway called GIP. These medications are often discussed together in weight management, but they have different dosing instructions and precautions.
Who may qualify for GLP-1 weight loss treatment?
For adult weight management, prescription medication may be considered for people with:
- A body mass index (BMI) of 30 or higher, or
- A BMI of 27 or higher with at least one weight-related health condition.
BMI is one part of the evaluation. Your clinician also considers your medical history, current medications, previous weight management efforts, and the potential benefits and risks of treatment.
You do not need to have diabetes to qualify for a medication approved for weight management.
Are GLP-1 medications available as pills?
Yes. GLP-1 weight management treatment includes oral options as well as injections.
Orforglipron, sold as Foundayo, is a once-daily prescription GLP-1 tablet approved for weight management in eligible adults. It can be taken with or without food and does not require an empty stomach.
Like injectable options, it is used alongside a reduced-calorie eating plan and increased physical activity. An oral medication still requires medical evaluation, gradual dose adjustments, and follow-up. Your clinician can help determine whether a pill or an injectable medication fits your health needs. Available options depend on your eligibility and the treatments offered by your provider.
Wegovy (semaglutide) is also available as a once-daily tablet for eligible adults, offering an alternative to weekly injections. Your clinician can help determine which form is appropriate and explain the tablet’s specific instructions.
How much weight can you lose?
These medications can help eligible patients achieve meaningful weight loss, but results vary. Your response depends on the medication, dose, duration of treatment, consistency, and individual health factors. Progress happens over months, and the scale may not change steadily every week. A useful treatment plan looks beyond pounds alone. It also considers nutrition, physical function, side effects, and weight-related health conditions.
What happens before you start treatment?
Treatment begins with a medical evaluation. Your clinician may review:
- Your height, weight, and weight history
- Medical conditions and family history
- Current medications and supplements
- Pregnancy plans and contraception
- Previous weight loss treatments
- Whether laboratory testing is needed
This evaluation helps determine whether medication is appropriate and which option may fit your needs.
How are GLP-1 medications taken?
Many injectable weight management medications are taken once weekly. Some oral options, including orforglipron, are taken once daily.
Treatment typically begins at a low dose and increases gradually according to the medication’s schedule and your response. Starting doses help your body adjust; they are not necessarily the doses used for ongoing weight management.
Do not increase your dose on your own or combine weight loss medications without guidance from your prescriber. Follow-up helps your clinician assess progress, manage side effects, and decide whether a dose change is appropriate.
What are the common side effects?
Common side effects include:
- Nausea
- Vomiting
- Diarrhea
- Constipation
- Abdominal discomfort
Some people notice more symptoms when starting treatment or increasing a dose. Smaller meals, stopping when comfortably full, and maintaining hydration may help.
Contact your clinician if symptoms persist or interfere with eating and drinking. Seek prompt medical care for severe or persistent abdominal pain, repeated vomiting, or inability to keep fluids down.
Serious risks can include pancreatitis, gallbladder problems, and kidney injury related to dehydration. Severe allergic reactions require emergency care.
Who should discuss extra precautions before treatment?
Semaglutide, tirzepatide, and orforglipron are not appropriate for everyone.
These medications are contraindicated in people with a personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN2). This warning concerns a specific thyroid cancer, rather than every thyroid condition.
Tell your clinician about severe stomach-emptying problems, previous pancreatitis, gallbladder disease, kidney or liver problems, diabetic eye disease, and any diabetes medications you take. Certain diabetes medications can increase the risk of low blood sugar when used with these treatments.
Weight loss medication should not be used during pregnancy. Semaglutide should be stopped at least two months before a planned pregnancy. Discuss pregnancy planning and breastfeeding before starting any treatment.
Some medications can affect oral hormonal birth control:
- Tirzepatide: Switch to a nonoral contraceptive method or add a barrier method for four weeks after starting and for four weeks after each dose increase.
- Orforglipron: Switch to a nonoral contraceptive method or add a barrier method for 30 days after starting and for 30 days after each dose increase.
Your clinician should also review possible interactions with other medications.
Tell your surgical or anesthesia team if you take one of these medications before a procedure.
Do you still need healthy eating and exercise?
Yes. Medication works alongside a sustainable eating and activity plan.
Because your appetite may decrease, eating enough nutritious food still matters. Adequate protein and strength-building activity can help support muscle during weight loss.
Your clinician can help tailor recommendations to your health, abilities, and routine. The goal is to build habits you can maintain while using medication when appropriate.
Will you need treatment long term?
Obesity is a chronic condition, and some patients benefit from ongoing medication.
Weight regain can occur after stopping treatment. Before discontinuing, discuss a maintenance plan with your clinician, including nutrition, activity, follow-up, and alternative options when needed.
Can you get GLP-1 weight loss treatment online?
For some adults, telehealth can provide a convenient way to begin a weight management evaluation and attend follow-up visits.
An online visit does not guarantee a prescription. A clinician must determine whether treatment is appropriate, and some patients need laboratory testing or an in-person assessment.
