Wegovy is one of the most talked-about weight loss medications right now, but it’s not available to everyone who wants to lose weight. There are specific criteria that doctors must follow when prescribing it for weight management.
Your BMI needs to meet certain thresholds, and there are other medical factors doctors consider too. Knowing these requirements beforehand will save you time and help set realistic expectations.
Wegovy can help with significant weight loss when used properly. Clinical trials show people typically lose around 15% of their body weight over 68 weeks – that’s much more than most achieve with diet and exercise alone.
Wegovy’s main ingredient, Semaglutide, works by copying a hormone your body makes called GLP-1. This hormone tells your brain you’re full and slows down how fast food leaves your stomach. The result? You feel less hungry and stay satisfied longer after eating.
You inject Wegovy once a week using a pre-filled pen. Most people start seeing results within the first month, with the biggest weight loss happening over several months.
But Wegovy isn’t a miracle cure. Like other weight loss drugs like Mounjaro, it works best alongside a reduced-calorie diet and regular physical activity. Think of it as a tool that makes sticking to healthier habits much easier, not a replacement for them.
Not everyone who wants to lose weight can get Wegovy. Your GP, doctor or pharmacist has to follow specific guidelines when deciding whether to prescribe it.
Your body mass index (BMI) is the main factor determining whether you qualify for Wegovy. You need a BMI of 30 or higher (obesity), or a BMI of 27 or higher (overweight) if you have weight-related health problems.
To put this in perspective, someone who’s 5’6″ would need to weigh at least 186 pounds (BMI 30) to qualify. If they have diabetes or high blood pressure, they’d qualify at 168 pounds (BMI 27).
Wegovy is available on the NHS, but the requirements are often higher due to funding constraints. Private services like Click2Pharmacy follow the original clinical trial criteria, meaning you might qualify for Wegovy privately even if you don’t meet the threshold of NHS or specialist weight management services.
You can calculate your BMI beforehand using online BMI calculators. Just remember that BMI alone isn’t the only thing considered – your overall health picture matters too.
If your BMI is between 27 and 29.9, you must have at least one weight-related health condition to qualify for Wegovy. These conditions show that your weight is already affecting your health.
The most common qualifying conditions include:
There are many Wegovy benefits beyond weight loss, so some doctors also consider conditions like fatty liver disease or polycystic ovary syndrome (PCOS).
Having one of these conditions alongside a BMI of 27 or higher puts you in the same category as someone with a BMI over 30. It shows that losing weight isn’t just about appearance – it’s medically necessary for your health.
Some people shouldn’t take Wegovy, even if they meet the BMI requirements. Safety comes first, so there are several situations where doctors won’t prescribe it.
Wegovy isn’t safe during pregnancy or while breastfeeding. If you’re trying to get pregnant, planning to become pregnant, or are currently pregnant, you shouldn’t take Wegovy.
The medication can harm your unborn baby, and there isn’t enough research on how it affects breast milk. If you become pregnant while taking Wegovy, stop immediately and contact your doctor or pharmacist.
Women of childbearing age should use effective contraception while taking Wegovy. It’s also recommended to stop the medication at least two months before trying to conceive.
You can’t take Wegovy if you’re allergic to semaglutide (the active ingredient) or any other ingredients in the injection. Signs of an allergic reaction include rash, itching, swelling, severe dizziness, or trouble breathing.
If you’ve had a serious allergic reaction to any GLP-1 receptor agonist medications before, Wegovy isn’t suitable for you. This includes medicines like Ozempic, Trulicity, or Victoza.
Always tell your doctor about any drug allergies you’ve had in the past, even if they seem unrelated. They need the whole picture to prescribe safely.
Wegovy is only approved for adults aged 18 and over. There isn’t enough research on its safety and effectiveness for teenagers or children, so doctors won’t prescribe it to anyone under 18.
There is no specific upper age limit for older adults, but doctors are more cautious. They’ll examine your overall health, other medications you’re taking, and whether you’re at higher risk for side effects.
If you’re over 65, your doctor might start you on a lower dose or monitor you more closely during the first few months of treatment.
Several medical conditions make Wegovy unsuitable or require extra caution. You shouldn’t take Wegovy if you have a personal or family history of medullary thyroid carcinoma (a type of thyroid cancer) or Multiple Endocrine Neoplasia syndrome type 2.
People with severe kidney disease, active gallbladder disease, or a history of pancreatitis need careful evaluation before starting Wegovy. These conditions can get worse with the medication.
If you have type 1 diabetes, diabetic retinopathy, or severe gastrointestinal disease, your doctor will need to weigh the risks and benefits very carefully. Mental health conditions like severe depression or eating disorders also require special consideration.
Some medications don’t mix well with Wegovy, so your doctor needs to know everything you’re taking – including over-the-counter medicines, supplements, and herbal remedies.
Insulin and other diabetes medications need dose adjustments when you start Wegovy, as the combination can cause dangerously low blood sugar. Blood thinners like warfarin might also need monitoring, as weight loss can affect how these drugs work.
If you take medications that slow stomach emptying (like some antidepressants or pain medications), they might not work as well with Wegovy. Oral contraceptives could also be less effective, so additional contraception might be needed.
