Weight loss support for younger women, including PCOS
If weight has crept up in your 20s or 30s, or PCOS makes it harder to shift, you are not imagining it. UK-licensed GLP-1 treatment, prescribed by a registered pharmacist, may help. You pay only if you are approved.
Why weight can be harder to shift in your 20s and 30s
Losing weight is not only about willpower. For many younger women, and especially with PCOS, the body works against the usual advice. These are some of the reasons the same effort does not always give the same result.
PCOS and insulin
Polycystic ovary syndrome is common, and many women with PCOS have higher insulin levels. This can make it easier to store fat and harder to lose weight, even with a careful diet.
Appetite and food noise
Constant hunger and thoughts about the next snack, often called food noise, can wear down the best intentions. It is a physical signal, not a character flaw.
Hormones and cycles
Hormonal changes across the month can affect appetite, cravings and energy. For some women this makes steady progress feel like two steps forward and one step back.
Busy, stressful lives
Work, study and broken sleep keep stress hormones high, which can encourage the body to hold on to weight. Life in your 20s and 30s is rarely built around a strict routine.
If the diet that works for your friends does not work for you, it is not because you are trying less hard. For many younger women, and with PCOS, the biology is simply different.
How GLP-1 treatment can help
GLP-1 medicines such as Mounjaro and Wegovy are prescription-only treatments that support weight loss in suitable people. They are not a quick fix, and they are not right for everyone. Like all medicines, they can cause side effects, so they are prescribed and supervised by a clinician who checks the treatment is safe and appropriate for you before you start.
The effect most people describe is the same. The constant background hunger quietens down. The thinking about the next snack, the second helpings and the late-night picking, often called food noise, eases off. When hunger is no longer fighting you all day, sensible eating stops feeling like a battle.
In clinical trials at 72 weeks, Mounjaro produced an average 22.5% reduction in body weight and Wegovy an average of 20.7%. These are averages from trials, not a promise. Individual results vary depending on your starting weight, your dose, your lifestyle and how long you stay on treatment.
The medicine does not do the work on its own. What it does is make the rest possible, which matters most when your biology has stopped cooperating.
Treatments for weight loss injections for women
Suitability is decided by our prescribing pharmacist after a clinical assessment, not by a form. Generally, GLP-1 treatment is considered for adults with a BMI over 30, or over 27 with a weight-related health condition. Mounjaro is the most requested by younger women.

What the pharmacist checks
Every consultation is reviewed personally by the prescribing pharmacist. There is no automated approval, and you pay only if treatment is approved.
The two routes to eligibility in the UK are a BMI of 30 or above, or a BMI between 27 and 29.9 together with a weight-related health condition. Polycystic ovary syndrome (PCOS) is one of the recognised weight-related conditions the pharmacist will consider, alongside others such as high blood pressure, prediabetes or high cholesterol.
You do not need a formal PCOS diagnosis to be considered, and PCOS on its own is not a shortcut past the BMI thresholds. You declare your health conditions and current medicines during the consultation, and the pharmacist reviews everything together before any prescription is issued. If you are trying for a baby, pregnant or breastfeeding, GLP-1 treatment is not suitable, so tell the pharmacist about this and about any contraception you use.
Be honest on the form. The assessment exists to keep you safe, not to catch you out. If treatment is not right for you, the pharmacist will say so plainly and explain why.
What helps alongside the medicine
The women who do best treat the medicine as one part of the plan. These simple habits protect muscle and steady your progress.
Prioritise protein
Protein at every meal protects muscle and keeps you full for longer. It also helps steady energy through the day.
Keep moving
Not punishing workouts. Daily walks and simple strength work two or three times a week hold on to muscle and protect your metabolism.
Drink more water
Easy to forget, and it helps with both appetite and energy through the day.
Stay supervised
Prescriptions are reviewed every 3 months. Regular check-ins mean your dose and progress are monitored and any side effects are managed early.
