Research reveals why women experience worse side effects from weight loss drugs
A new report has uncovered significant biological differences between men and women in their response to popular weight loss medications like Ozempic and Zepbound, according to a recent study.
The report provides insights into why female patients, who make up 70 per cent of those taking GLP-1 drugs, experience more severe side effects despite achieving greater weight loss results.
With obesity affecting two billion people worldwide and the treatment market projected to reach $200 billion by 2031, these findings could change how medications are prescribed to millions of patients.
The study showed that women experience 2.5 times higher rates of nausea and vomiting compared to men when taking GLP-1 medications.
Researchers identified a biological explanation: female mice have nearly double the GLP-1 receptor expression in brain regions associated with nausea.
“This isn’t just about improving GLP-1 drugs – it’s about rethinking how we design future therapies for real-world patients from the start,” said David Tingley, co-founder and CEO of Olio Labs, which published the research this week,
The findings suggest that personalised dosing based on a woman’s menstrual cycle could reduce side effects and discontinuation rates.
Researchers found that higher oestrogen levels correlate with more severe side effects, highlighting the role hormones play in medication response.
Founded in 2023 by neuroscientists and computational biologists, Olio Labs takes a different approach to drug development by focusing on whole-body systems rather than individual molecules.
Their Combination Design Engine (CoDE) platform analyses human medical records, biological data, and neural circuit maps to develop treatments tailored to specific populations.
Patricia Martin, Olio Labs advisor and former COO of Lilly Diabetes, said the company’s methodology combines a computational approach with validated preclinical models and real patient data to develop better treatments for specific populations.
“Their patient-first approach has potential to advance personalised medicine,” she said.
The company has secured £3.6m in funding from investors including Boom Capital, Overwater Ventures, Pioneer Fund, and Y Combinator.
“Obesity is one of the largest problems facing healthcare systems today, and Olio’s research will help millions of women have a better solution without the debilitating side effects,” said Kristina Simmons, founder and managing partner of Overwater Ventures.
As the obesity epidemic continues to grow globally, this research highlights the need for sex-specific approaches to medication development and administration.
This could mark a shift in how drugs are designed and prescribed in the future.
The World Health Organization (WHO) has launched an AI tool in beta to help policymakers, experts and healthcare professionals access sexual and reproductive health information faster.
Called ChatHRP, the tool was created by WHO’s Human Reproduction Programme and draws only on verified research and guidance collected by HRP and WHO.
It uses natural language processing and retrieval-augmented generation to produce referenced content and cut the time spent searching through documents across different platforms and databases.
WHO said ChatHRP also has multilingual capabilities and low-bandwidth functionality to support use in a wide range of settings.
The beta-testing phase is aimed at a broad professional audience, including policymakers, healthcare workers, researchers and civil society groups.
WHO said the tool can help users quickly access up-to-date evidence, find sources for academic work and verify information on sexual and reproductive health and rights.
Examples of questions it can answer include the latest violence against women data in Oceania for women aged 15 to 49, recommendations on managing diabetes during pregnancy, and whether PrEP and contraception can be used at the same time. PrEP is medicine used to reduce the risk of getting HIV.
WHO added that the system will be updated regularly as new HRP materials are published and includes a feedback loop so users can flag gaps in the information provided.
The launch comes amid wider concern about misinformation in sexual and reproductive health.
A 2025 scoping review found that misinformation in digital spaces is a systemic issue that can undermine human rights, reinforce discriminatory social norms and exclude marginalised voices.
The review also said misinformation can affect health systems by shaping provider knowledge and practice, disrupting service delivery and creating barriers to equitable care.
WHO said ChatHRP is intended to give users streamlined access to reliable information as a counter to “algorithms, opinions, or misinformation”.

Cervical cancer elimination in the EU is becoming achievable as HPV vaccination coverage rises, a new report says.
As Europe marks European Immunisation Week 2026, the European Centre for Disease Prevention and Control said progress in human papillomavirus vaccination is continuing across the EU and European Economic Area.
All EU and European Economic Area countries now recommend HPV vaccination for adolescent girls and boys as part of their immunisation programmes, marking a major step forward in Europe’s cancer prevention efforts.
Bruno Ciancio, head of unit, directly transmitted diseases and vaccine preventable diseases at the European Centre for Disease Prevention and Control, said: “The elimination of cervical cancer in the EU/EEA is becoming an achievable goal, thanks to the HPV vaccination programmes.
“The progress we are seeing across Europe demonstrates what can be accomplished when countries invest consistently in effective immunisation strategies.
“We are closely monitoring this progress and actively supporting countries to accelerate uptake and move faster towards cervical cancer elimination.”
According to the report, three EU and European Economic Area countries, Iceland, Portugal and Norway, have reached the 2024 EU Council Recommendation target of 90 per cent HPV vaccination coverage among girls by the age of 15.
Fifteen years after HPV vaccination programmes were introduced in Europe, a growing body of evidence confirms the vaccine is highly effective in preventing cervical cancer.
Large-scale studies from Sweden, the Netherlands and Denmark, as well as other parts of the world, have shown significant reductions in HPV infections and precancerous lesions, which are abnormal cell changes that can develop into cancer if left untreated, alongside falling cervical cancer rates among vaccinated women.
Since 2020, European countries have reported a decreased incidence of cervical cancer among vaccinated women.
Studies from Sweden, Denmark and the UK show that early administration of the vaccine increases its full protective potential.
A Swedish study suggested that vaccinating girls before their 17th birthday reduced the incidence of cervical cancer by 88 per cent.
An additional six-year follow-up found a sustained reduction in cervical cancer risk and a population-level decline in invasive cervical cancer incidence after HPV vaccination.
The report showed that vaccination programmes and health system design are critical factors in reaching high levels of HPV vaccination coverage.
Evidence from across Europe showed that school-based vaccination programmes are particularly effective and tend to reach higher levels of coverage among both girls and boys.
