5 Times When Women are More at Risk of Blood Clots
Thrombosis, or blood clotting, can affect people of all ages, races, and genders. And while both men and women are at risk of getting a blood clot, there are several stages in a woman’s life when that risk may be higher.
Thrombosis is the formation of blood clots in the circulatory system, which can be dangerous if the clot blocks blood flow to vital organs, causing serious complications, such as deep vein thrombosis (DVT) or pulmonary embolism (PE).
According to the World Thrombosis Day (WTD) campaign, blood clots can happen to anyone at any time. Surgery, hospitalisation, and cancer raise the risk for everyone, but certain ages and factors in a woman’s life increase the possibility of getting a thrombosis.
Pregnancy
In general, women may be at a slightly higher risk of developing thrombosis during pregnancy and shortly after delivery. A woman’s body undergoes significant hormonal changes when she is pregnant, says Dr Helen Okoye, a leading Nigerian thrombosis specialist who is part of the World Thrombosis Day (WTD) steering committee.
“A pregnant woman’s blood becomes more prone to clotting to prevent excessive bleeding during childbirth, which places her at an increased risk of a DVT and PE. The risk of thrombosis remains elevated for a few weeks after childbirth. During this time, the body slowly returns to its pre-pregnancy state, and the risk of clotting decreases gradually,” explains Dr Okoye.
Hormonal contraceptives
Some forms of hormonal contraceptives, particularly those containing estrogen, can also increase the risk of blood clot formation, although the risk is generally considered low. Women who use combined oral contraceptives (containing both estrogen and progestin) or hormone-releasing intrauterine devices (IUDs) may be at a slightly higher risk of thrombosis.
Hormone replacement therapy
Hormone replacement therapy (HRT) involves taking hormones to alleviate menopausal symptoms and manage hormonal imbalances. Women undergoing HRT may have an increased risk of thrombosis, particularly if the therapy includes estrogen, says Dr Okoye. “Although the risk of thrombosis with HRT is generally low, it is higher than in women who are not taking hormone therapy. The risk may also be more for women who have additional risk factors, such as a personal or family history of blood clots, obesity, or a sedentary lifestyle. If you are using or considering HRT, discuss the potential risks with your healthcare provider,” advises Dr Okoye.
Medical conditions
Certain medical conditions, such as obesity and some inherited blood clotting disorders, can elevate the risk of thrombosis in women. Conditions that affect hormone levels, like polycystic ovary syndrome (PCOS), can also contribute to an increased risk of thrombosis, and some autoimmune disorders, such as systemic lupus erythematosus (SLE), which is much more common in women, can lead to an increased risk of blood clotting. Additionally, women with specific types of cancer may have a higher probability of getting a thrombosis.
Strokes
If a blood clot obstructs the flow of blood to a part of the brain, it can cause a stroke, the severity of which depends on the size and location of the blocked blood vessel.
Women have some differences in stroke risk compared to men, points out Dr Okoye. Stroke is more common in women than in men, with a 1 in 4 risk of stroke for women after age 25. Stroke is also the fifth leading cause of death for women, according to the Centers for Disease Control and Prevention (CDC).
Women, like men, can experience strokes at any age, but there are certain life stages and factors that can increase the risk of stroke in women. “Women tend to live longer than men on average, and stroke risk increases with age. Since stroke is more common in older individuals, the longer life expectancy of women contributes to their higher overall stroke incidence,” explains Dr Okoye.
Pregnant women, especially those with certain conditions like preeclampsia, gestational diabetes, or clotting disorders, may also have an increased risk of stroke.
The weeks following childbirth can also be a time of increased stroke risk for some women, particularly if they experienced complications during pregnancy or delivery.
Women who experience migraines with aura may also have a higher risk of stroke, especially if they have other risk factors such as smoking or using oral contraceptives. Atrial fibrillation is another red flag.
“This heart rhythm disorder is more common in women and significantly increases the risk of stroke due to the potential for blood clots forming in the heart and traveling to the brain. Hypertension is also a significant risk factor for stroke, and it can affect women at any age,” says Dr Okoye.
Lessen the risk
It is important to note that each woman’s risk of stroke or thrombosis is influenced by a combination of factors, including genetics, lifestyle, and medical history.
“Women need to be aware of their own personal risk factors and manage any existing health conditions they may have,” advises Dr Okoye. “If you’re concerned at all, consult a healthcare professional for personalised advice and risk assessment. Regular medical check-ups, adherence to prescribed medications, and a healthy lifestyle are all ways to reduce your risk of thrombosis,” she says.
“Strive to maintain a healthy weight. Being overweight or obese can increase the risk of blood clots, so follow a balanced diet that is rich in fruits, vegetables, whole grains, lean proteins, and healthy fats,” advises Dr Okoye. “If you smoke, stop as soon as possible. Smoking damages blood vessels and increases the risk of blood clots. And drink lots of water to keep your body well-hydrated, which can help prevent blood from thickening and forming clots.”
Staying active is crucial, too. According to the WTD campaign, regular physical activity helps improve blood circulation and reduces the risk of blood clots. WTD campaign’s 2023 theme is “Move Against Thrombosis”, and they advise people to incorporate exercise or regular movement into their everyday routine.
It’s important for women to be aware of all the above risk factors and what they can do about it, concludes Dr Okoye. “If you have questions about your risk of thrombosis, it’s essential to speak with your healthcare provider. They can assess your individual risk factors and provide appropriate guidance and preventive measures if needed.”
Finally, familiarise yourself with the signs and symptoms of blood clots, such as swelling, pain, tenderness, warmth, and redness in the affected area. If you suspect a blood clot, seek immediate medical attention.

The federal government has urged global investors and innovators to tap into the Nigerian healthcare ecosystem, which is projected to grow by 7.1 per cent, reaching a market value of $161.7 million by 2027.
This advice was given by the Minister of State for Health and Social Welfare, Mr Isiaq Salako, at the opening of the World Health Expo (WHX in Lagos 2026), formerly known as Medic West Africa, on Tuesday in Lagos.
The broader West African market is expected to reach more than $11 billion, providing investors with an opportunity to get a good return on investment.
“Nigeria is open for healthcare investment. We want platforms like WHX in Lagos to serve as a critical conduit for translating this investment ambition into tangible technology access for our hospitals and patients,” the Minister, who declared the event open on behalf of President Bola Tinubu, said.
He praised the organisers of the expo, which welcomed over 8,000 healthcare professionals and 500 exhibitors spanning 40 countries, for growing the programme into a vital catalyst for West African healthcare transformation.
Addressing the stark reality that between 85 per cent and 99 per cent of medical equipment and in vitro diagnostics in West Africa are currently imported, Mr Salako outlined aggressive federal interventions designed to dismantle supply chain vulnerabilities and skyrocket local manufacturing capabilities.
He also spotlighted key presidential directives, including the Presidential Initiative to Unlock Healthcare Value Chains (PVAC) and the Presidential Executive Order for the Pharmaceutical and Allied Sectors, both engineered to catalyse health security, drive economic growth, and generate employment through strategic private-sector collaborations and Public-Private Partnerships (PPPs).
“Our commitment to improving access to modern equipment and technologies in hospitals is backed by concrete action. The government has inaugurated the $1.2 billion Sector-Wide Approach (SWAP) initiative, a comprehensive overhaul addressing financing, workforce development, and infrastructure.
“Furthermore, for the 2025 fiscal year, the Federal Government committed N402 billion specifically for health sector infrastructure investment,” he stated, also highlighting an expansive health infrastructure upgrade program in partnership with the Nigeria Sovereign Investment Authority (NSIA).
According to him, this phased initiative is actively delivering oncology and nuclear medicine centres across six tertiary hospitals, alongside establishing 22 modern medical diagnostic centres, seven cardiac catheterisation laboratories, and expanded radiology and clinical pathology capabilities distributed across Nigeria’s six geopolitical zones.
Also speaking, the chief executive of EHA Clinics, Dr Ifunanya Ilodibe, stressed the urgent need to support and unify fragmented growth within the healthcare system, noting that WHX serves as the precise ecosystem platform required to bring together policymakers, clinicians, and investors to move actionable strategies forward.
Also, the President of the Healthcare Federation of Nigeria (HFN) and Country Director of PharmAccess, Njide Ndili, said, “HFN bridges the gaps in health financing, opening up critical connections to achieve true health sovereignty,” praising Africa CDC’s historical intervention, particularly during the Ebola crisis and urged participants to utilise the WHX exhibition floor to forge collaborations capable of scaling locally produced medical equipment.
The Lagos State Commissioner for Health, Mr Akin Abayomi, on his part, highlighted the enforcement of the National Health Insurance Authority (NHIA) Act in Lagos State as a landmark regulatory milestone. The Act mandates health insurance for all residents, structuring the financial environment to guarantee medical protection across various socioeconomic levels.
Delivering the keynote address, the Special Regional Representative of the Director General of the Africa CDC Western Regional Coordinating Centre, Prof. Aliko Ahmed, called on leaders in geopolitical positions to enact liberating trade policies aligned with the African Continental Free Trade Area (AfCFTA) to shape the continental agenda, emphasising that the Africa CDC will fiercely prioritise building trust in locally manufactured healthcare products.
WHX in Lagos 2026 runs for three days, featuring accredited forums, cutting-edge product showcases, and high-level networking tracks designed to translate billions in public and private investment into immediate technology access for hospitals and patients.

The coroner’s inquest into the death of 21-month-old Nkanu Adichie-Esege, son of renowned author Chimamanda Ngozi Adichie, suffered a major setback on Wednesday after Euracare Multi-Specialist Hospital informed the coroner’s court that it had obtained an order of the Lagos State High Court staying further proceedings in the probe.
The matter came before Coroner Magistrate Atinuke Adetunji at Court 9, Igbosere Magisterial District, Yaba, Lagos, and was scheduled for the commencement of witness’ testimony.
Counsel to Euracare Multi-Specialist Hospital, Professor Taiwo Osipitan (SAN), told the court that the hospital had initiated judicial review proceedings challenging, among other issues, the jurisdiction of the Coroner’s Court to conduct the inquest in the absence of the deceased’s body.
He disclosed that the High Court had granted leave for the judicial review application and ordered that the leave operate as a stay of proceedings pending the determination of the suit.
The senior advocate also informed the court that although the Lagos State Attorney-General’s Office denied seeing the originating processes from the High Court, proof of service was available.
Responding on behalf of the family, Mr Kemi Pinheiro (SAN) confirmed receipt of both the originating processes and the High Court order.
While acknowledging the obligation of all parties to comply with court orders, he informed the coroner that the family had already filed four witness statements on oath, including that of Dr Ivara Esege, as well as statements from independent medical experts from Nigeria and the United States, who are expected to testify at the inquest.
Mr Pinheiro urged the court not to adjourn the matter indefinitely, but to a definite date after the court vacation to enable parties to report on developments in the High Court proceedings.
He also highlighted the need for transparency and public confidence in the fact-finding process, saying, “He who is innocent does not fear an open inquest.”
Counsel representing Atlantis Paediatric Hospital supported the request for a definite adjournment rather than an indefinite postponement.
Following submissions by counsel, the Coroner adjourned the matter until October 8, 2026, for a report on the status of the High Court proceedings.

About $50 million has been promised by Gavi, the Vaccine Alliance, through its First Response Fund (FRF), to support the response to the ongoing Bundibugyo ebolavirus outbreak.
A statement from the organisation made available to Business Post on Monday said up to $40 million would be available to enable accelerated access to investigational doses and, eventually, approved vaccines, while a further $10 million would support outbreak response and protection of routine immunisation services in impacted countries.
“We need to act now to ensure that, once one or more vaccine candidates are ready, manufacturers are in a position to start producing doses at scale,” the chief executive of Gavi, Dr Sania Nishtar, was quoted as saying.
“Leveraging this allocation, Gavi will work closely with CEPI and partners to design the right incentives to achieve this goal, exploring all options, including potential Advance Purchase Commitments.
“This effort, alongside ensuring emergency funds are on hand to support outbreak response and protect routine immunisation services in the communities impacted, is exactly what our First Response Fund was designed for,” Dr Nishtar added.
The First Response Fund is the only globally approved mechanism that allows “at-risk” financing for scaled-up production of vaccines under development. This means Gavi is able to make vital early investments even when development outcomes are uncertain.
The $40 million in immediate surge financing that has been approved today will enable manufacturers of the leading candidates of a vaccine against the Bundibugyo virus to directly commit to high-capacity manufacturing.
This, in turn, will ensure that, as soon as clinical trials demonstrate positive outcomes, investigational vaccine doses could be deployed rapidly to support outbreak response.
Looking to the longer-term, Gavi will also provide incentives for manufacturers to adopt the fastest pathways towards WHO Emergency Use Listing (EUL) and/or WHO Prequalification (PQ), which are critical global approvals that will enable the rapid use of these vaccines in future emergencies.
In the coming weeks, Gavi will finalise the design of a financial mechanism that leverages the $40 million FRF allocation to achieve these vaccine access goals, in close partnership with the Coalition for Epidemic Preparedness Innovations (CEPI) as well as WHO, Africa Centres for Disease Control and Prevention (Africa CDC) and UNICEF.
The final design will take into account the characteristics of individual vaccine candidates and the needs of their manufacturers and may include mechanisms such as Advance Purchase Commitments. Work will also be undertaken to ensure successful candidates from African-based vaccine manufacturers can benefit from accelerated support through Gavi’s African Vaccine Manufacturing Accelerator (AVMA) initiative.
In addition to these investments, Gavi will also immediately release US$ 10 million to support countries and partners with outbreak response.
This funding will support implementation of national outbreak response plans, including targeted investments to protect routine immunisation, protect health care workers and ensure readiness for future vaccines. Gavi will work closely with countries, partners including Africa CDC, WHO, UNICEF, World Bank, and donors to ensure these investments complement other efforts.
