Introduction
Semaglutide is the most-studied GLP-1 medication for weight loss, with extensive data in women. The STEP clinical trial programme included a majority of female participants, providing robust evidence for efficacy and safety in women. This guide covers women-specific aspects of semaglutide treatment.

Efficacy in Women
Women responded comparably to men in clinical trials. In STEP 1, the average weight loss was 14.9% of body weight over 68 weeks1. Sub-analyses showed consistent efficacy across age groups, BMI categories, and hormonal status.
Benefits Beyond Weight Loss
For women specifically, semaglutide offers additional benefits:
- PCOS improvement — weight loss with semaglutide improves insulin sensitivity, reduces androgen levels, and may restore menstrual regularity
- Cardiovascular protection — particularly relevant for post-menopausal women at higher CV risk
- Blood sugar control — benefits women with gestational diabetes history or pre-diabetes
- Reduced inflammation — may benefit conditions like endometriosis(Based on MOH guidelines and prescribing information)
Hormonal Considerations
Women's hormonal health interacts with semaglutide in several important ways that require careful management.
Menstrual Cycle Effects
- Weight loss of any kind can affect menstrual regularity
- Some women report lighter or heavier periods during treatment(Based on MOH guidelines and prescribing information)
- Cycle changes usually stabilise as weight stabilises
- Report significant menstrual changes to your doctor
Fertility
- Weight loss improves fertility, especially in women with PCOS
- Must stop semaglutide at least 2 months before conception
- Pre-conception weight loss planning should be discussed with your doctor
Menopause
- Semaglutide is effective in peri/post-menopausal women
- Can be used alongside HRT without significant interactions
- Particularly beneficial for addressing menopausal abdominal weight gain
Dosing for Women
Dosing is the same as for men — no gender-specific dose adjustment is needed.
| Phase | Dose | Duration |
|---|---|---|
| Initiation | 0.25 mg weekly | 4 weeks |
| Escalation | 0.5 mg → 1.0 mg → 1.7 mg → 2.4 mg | Each 4 weeks |
| Maintenance | 2.4 mg weekly (or highest tolerated) | Ongoing |
Some women are more sensitive to GI side effects and may benefit from slower dose escalation.

FAQ
Semaglutide delays gastric emptying, which may theoretically reduce oral contraceptive absorption. Discuss with your doctor — you may need additional contraception or a switch to a non-oral method.
Yes. GLP-1 medications improve insulin sensitivity and promote weight loss — both of which address core PCOS mechanisms. Some studies show improvements in menstrual regularity and androgen levels with weight loss2.
Facial volume loss can occur with significant weight loss from any cause. Adequate protein intake (1.2–1.6 g/kg/day), slower weight loss, and hydration can minimise this. It's not specific to semaglutide.
Semaglutide is not recommended during breastfeeding due to limited safety data. Discuss timing of treatment with your doctor.
No significant interactions have been identified. Semaglutide can be used alongside HRT patches, gels, or tablets.
