The thyroid gland, a small butterfly-shaped organ located at the front of the neck, plays a vital role in regulating metabolism, heart rate and body temperature.

Yet thyroid disorders often go undetected, especially among women, whose symptoms are frequently mistaken for stress, ageing or normal hormonal changes.

Speaking with PT Health Watch, reproductive endocrinologist Oladapo Ashiru said women are far more likely than men to develop thyroid disorders, citing Nigerian studies that reported female-to-male ratios ranging from 6.3:1 to as high as 98:1.

According to Mr Ashiru, recognising the warning signs early is important because untreated thyroid disorders can affect fertility, pregnancy and overall quality of life.

Symptoms often overlooked

Mr Ashiru explained that thyroid disorders generally occur in two forms: hypothyroidism, where the gland is underactive, and hyperthyroidism, where it is overactive.

An underactive thyroid commonly causes unexplained weight gain, sensitivity to cold and hair thinning, while an overactive thyroid may lead to unexplained weight loss, heat intolerance and a faster metabolism.

“If the thyroid is underactive, there will be increased weight or unexplained weight gain. If it is overactive, there will be unexplained weight loss. The person may feel too cold in a normal environment if it is underactive, or too hot in a cool environment if it is overactive,” he said.

Beyond these symptoms, women may experience irregular menstrual cycles, mood changes, anxiety, depression, constipation or frequent bowel movements.

Mr Ashiru, who is the Chairman and Chief Medical Director of Medical Art Centre, said women are also more likely to experience neck tightness caused by an enlarged thyroid gland, excessive tearing and persistent symptoms even after treatment.

By contrast, men more commonly present with heart palpitations.

He explained that because many thyroid symptoms resemble those associated with stress, menopause and other everyday conditions, thyroid disorders in women are often overlooked or diagnosed late.

Effects on fertility and pregnancy

Mr Ashiru said women between the ages of 30 and 49 face the highest risk of thyroid disorders, although younger women can also be affected.

He warned that untreated thyroid disease can interfere with ovulation, increase menstrual bleeding, raise the risk of miscarriage and contribute to complications after childbirth.

Women planning pregnancy, he advised, should consider thyroid screening to detect and treat any underlying condition before conception.

The endocrinologist also highlighted postpartum thyroiditis, an inflammation of the thyroid gland that can occur after childbirth.

According to him, new mothers should not dismiss persistent exhaustion as simply part of caring for a newborn, as it may signal an underlying thyroid disorder.

Screening and healthy habits

Mr Ashiru said thyroid disorders can be diagnosed through simple hormone tests available in many Nigerian hospitals and laboratories.

He recommended routine screening, particularly for women aged 35 years and above, pregnant women and people with a family history of thyroid disease.

Although some thyroid conditions are hereditary, he said healthy lifestyle habits may help support thyroid function.

These include getting adequate sleep, managing stress, eating a balanced diet with appropriate amounts of iodine and selenium-rich foods such as eggs, fish and beans, and engaging in regular physical activity.

He also encouraged stress management through family support, prayer and relaxation techniques, including deep-breathing exercises.

Some of his recommendations, including limiting processed foods, genetically modified foods and environmental toxins, reflect his clinical opinion on factors that may influence thyroid health.

Early diagnosis improves outcomes

Mr Ashiru said treatment depends on the type of thyroid disorder, with many patients responding well to thyroid hormone replacement therapy or other appropriate medications.

He stressed that early diagnosis remains the most effective way to prevent complications and improve quality of life.

Describing the thyroid as a vital organ, he said it regulates reproductive hormones and supports the proper functioning of the heart, skin and other body systems.

He also warned that exposure to environmental toxins may affect thyroid function and urged people to minimise avoidable environmental risks.

North accounts for most of Nigeria’s recorded maternal deaths – Report

Published

Women in northern Nigeria continue to bear a disproportionate burden of maternal deaths, with the Northwest and Northeast geopolitical zones accounting for about three-quarters of reported fatalities in health facilities, according to the 2026 Joint Annual Review (JAR) Statistical Book.

The report also highlights significant disparities in maternal health outcomes between rural and urban areas, with rural women recording a maternal mortality ratio of 656 deaths per 100,000 live births, compared with 444 deaths per 100,000 live births in urban areas.

Produced by the Federal Ministry of Health and Social Welfare, the report reviews the third year of implementation of the Health Sector Strategic Blueprint. It was presented at the third Nigeria Health Sector Joint Annual Review in Abuja on 10 November.

The findings highlight persistent inequalities in maternal healthcare access and outcomes, despite a reported decline in maternal deaths across health facilities nationally.

According to the report, Nigeria recorded thousands of maternal deaths in health facilities between January and September 2026, although the figures represent only deaths captured by the facility reporting system.

The ministry acknowledged that the figures could be underreported or overreported but described the data as reliable for monitoring trends in the health sector.

Maternal mortality remains high

Maternal mortality refers to the death of a woman during pregnancy, childbirth or within 42 days of the termination of pregnancy from causes related to or aggravated by the pregnancy or its management.

Most maternal deaths are preventable through timely access to quality antenatal care, skilled birth attendance, emergency obstetric services and appropriate postnatal care.

Despite the reported improvements, Nigeria’s maternal mortality ratio remains a major public health concern.

The JAR Statistical Book puts the country’s maternal mortality ratio at 572 deaths per 100,000 live births, significantly above the Sustainable Development Goal (SDG) target of fewer than 70 deaths per 100,000 live births by 2030.

The burden is particularly concerning given Nigeria’s contribution to global maternal deaths.

In its 2023 report, titled “Improving Maternal and Newborn Health and Survival and Reducing Stillbirths: Progress Report 2023”, the World Health Organisation (WHO) estimated that Nigeria recorded 82,000 maternal deaths, 181,000 stillbirths and 277,000 neonatal deaths in 2020.

The combined 540,000 deaths accounted for 12 per cent of global maternal, stillbirth and neonatal deaths, despite Nigeria contributing only six per cent of global live births.

The report ranked Nigeria second after India among countries with the highest combined burden of maternal deaths, stillbirths and neonatal deaths.

Reported maternal deaths decline

The JAR data indicate a downward trend in facility-reported maternal deaths over the review period.

The country recorded 5,391 maternal deaths in health facilities in 2024, compared with 4,455 in 2025.

The figure declined further in 2026, although the exact total requires confirmation against the final statistical table. The quarterly data also indicate improvements.

Following a peak in the second quarter of 2024, maternal deaths and the maternal mortality ratio generally declined. By the third quarter of 2026, the maternal mortality ratio had fallen to 128 deaths per 100,000 live births, representing a reduction of about 46 per cent from the earlier peak.

Maternal deaths during the same period also declined by approximately 40 per cent to 947.

However, these improvements have not been evenly distributed across the country.

Northern states bear the burden

According to the report, maternal deaths over the past three years were heavily concentrated in the Northwest and Northeast geopolitical zones.

By 2026, the two zones together accounted for approximately three-quarters of all documented maternal deaths in health facilities.

The five northern states with the highest maternal mortality burden were Kano, Borno, Jigawa, Yobe and Katsina.

While the national figures showed a downward trend, maternal deaths reportedly increased across the two northern zones, contrasting with reductions recorded in southern parts of the country.

In most southern states, fewer than 50 maternal deaths were reported. The states with the lowest recorded numbers included Osun (four deaths), Abia (five), Enugu (eight), Ekiti (nine), and Bayelsa (nine).

Maternal morbidity

Beyond deaths, the report also highlights the burden of maternal morbidity, including complications that can have lasting effects on women’s health, wellbeing and livelihoods. In 2026, approximately 3,060 women were diagnosed with vesicovaginal fistula (VVF), compared with 4,350 in 2025.

VVF is an abnormal opening between the bladder and vagina that can result in continuous, involuntary leakage of urine, often following prolonged or obstructed labour.

Of the women diagnosed in 2026, 1,737 underwent surgical repair, representing 56.8 per cent of those diagnosed. This was lower than in 2025, when 2,564 women (59 per cent) underwent repairs.

The Northwest and Northeast again recorded the highest burden, with 1,420 and 982 cases, respectively, in 2026. The figures underscore the need to strengthen access to emergency obstetric care, timely referrals and surgical treatment, particularly in underserved communities.

The woman who tested positive for Ebola in Nigeria and was evacuated to Switzerland for treatment has been discharged from hospital after making a full recovery.

She was discharged from Geneva University Hospitals on Wednesday, after medical personnel confirmed her recovery, Reuters reported on Thursday, quoting a statement from the hospital.

“After the medical team confirmed her full recovery, the cantonal physician authorised the patient being treated for Ebola virus disease to leave the Geneva University Hospitals (HUG) on 11 November 2026,” the hospital said.

The Uganda-born woman and her husband, a Swiss diplomat, were evacuated from Nigeria to Switzerland on 26 October. Her evacuation was confirmed by the Minister of Health and Social Welfare, Muhammad Pate.

The patient had returned to Abuja from Uganda on 3 October. She developed symptoms days later and was admitted to a private health facility before the Nigeria Centre for Disease Control and Prevention (NCDC) was notified. Laboratory tests confirmed the infection on 20 October.

Nigeria continues Ebola surveillance

The NCDC’s latest Ebola situation dashboard, updated on 12 November with data as of 11 November, lists one confirmed case, no deaths and seven negative cases.

It also shows that 62 contacts linked to the confirmed case have been identified. Of these, 52 have completed their mandatory 21-day follow-up, while 10 remain under monitoring.

The NCDC said its response includes contact tracing, investigation of reported alerts, laboratory testing, infection prevention and control measures, and surveillance at the country’s points of entry.

On 11 November, NCDC disclosed that Nigeria recorded no additional confirmed Ebola cases since the imported infection was confirmed.

The agency has urged healthcare workers to remain vigilant, ask patients about their travel and exposure histories, and promptly report suspected cases to public health authorities.

Regional outbreak continues

The situation in Nigeria is part of a wider outbreak of Bundibugyo virus disease affecting parts of Africa.

In its latest situation update published on 6 November, the World Health Organisation (WHO) said the DRC had recorded 10,668 confirmed cases and 5,198 deaths as of 3 November, across 67 health zones in eight provinces.

Kenya had recorded nine confirmed cases and two deaths, while Nigeria had reported one imported case. WHO said there had been no new confirmed cases in Kenya or Nigeria since its previous update.
