HEALTH NEWS — Tun Dr Siti Hasmah Mohamad Ali died at Malaysia’s National Heart Institute at about 9.20am on September 28, 2026. She was 100.
Her son, Mokhzani Mahathir, confirmed her death to Malaysian state news agency Bernama. She had celebrated her 100th birthday on July 12 and is survived by her husband, former Malaysian prime minister Tun Dr Mahathir Mohamad, and their seven children.
Dr Siti Hasmah was accorded a state funeral and laid to rest at the National Mausoleum. Tributes from Malaysian leaders and members of the public remembered not only her role beside Dr Mahathir, but also her own long record as a doctor, public-health advocate and role model for women.
Dr Siti Hasmah died at the National Heart Institute in Kuala Lumpur at about 9.20am on September 28. Her death was confirmed by her family, and she was later accorded a state funeral.
Her family and authorities had not publicly announced a cause of death at the time of publication. Being treated at a heart institute does not establish that a heart condition caused her death. KnowvaLife will not speculate without an official medical statement.
Who Was Tun Dr Siti Hasmah?
Born in Klang, Selangor, on July 12, 1926, Dr Siti Hasmah entered the King Edward VII College of Medicine in Singapore in 1947. The National University of Singapore says she was the only Malay woman in her cohort. She graduated in 1955 before completing her housemanship at Kuala Lumpur General Hospital.
She joined Malaysia’s government medical service and became a trailblazer within the Ministry of Health. In 1965, she became the first woman in Malaysia appointed as a medical officer in the Maternal and Child Health Department. In 1974, she became the first female doctor appointed as a State Maternal and Child Health Officer.
NUS honoured her with its Distinguished Alumni Service Award in 2018, recognising her sustained public-health service and her influence as a pioneer for women doctors in Malaysia and beyond.
A Pioneer in Maternal and Child Health
Dr Siti Hasmah’s early work took her to rural communities in Kedah, where healthcare access, sanitation and health information could be limited. Her work included maternal care, childhood immunisation, hygiene and public-health education.
Malay Mail reported that health records credit maternal-health initiatives in Kedah during her service with helping to reduce infant mortality from 75 deaths per 1,000 live births to six. The figure reflects the importance of organised public-health systems rather than the work of any one person alone, but it illustrates the scale of progress associated with sustained community care.
Regular care during pregnancy can identify risks, monitor mother and baby, and connect families with timely treatment and support.
Trained health professionals can recognise and manage complications during labour and childbirth.
Vaccination protects children against serious vaccine-preventable diseases and supports community health.
Clear, practical information helps families recognise warning signs and make informed health decisions.
Why Maternal Healthcare Still Matters
Maternal health covers care before pregnancy, during pregnancy and childbirth, and after birth. The World Health Organization says many maternal deaths are preventable when women receive timely, high-quality care from skilled health professionals.
Antenatal appointments are not only routine check-ups. They can help health teams detect or manage concerns such as high blood pressure, anaemia, infection and other complications. They also give parents an opportunity to discuss medicines, nutrition, vaccinations, mental well-being and plans for delivery.
Postnatal care is equally important. Recovery after childbirth, feeding support, newborn assessment, family planning and maternal mental health may all require attention in the weeks after birth.
Pregnancy care should be individualised. Keep scheduled appointments and contact a qualified healthcare professional if symptoms change or you are worried about yourself or your baby.
When Should Someone Seek Urgent Care in Pregnancy?
Pregnancy symptoms can have many causes, but certain changes need urgent medical assessment. Seek immediate help according to local medical guidance for symptoms such as:
- Heavy vaginal bleeding
- Severe abdominal pain
- Severe headache, blurred vision or sudden swelling
- Chest pain or difficulty breathing
- Seizures, fainting or loss of consciousness
- High fever or signs of a serious infection
- Reduced or absent fetal movement after movements have become established
- Any symptom that feels severe, sudden or rapidly worsening
Severe bleeding, breathing difficulty, chest pain, seizures, fainting or a rapidly worsening condition requires urgent medical attention. In Singapore, call 995 for an emergency ambulance; elsewhere, use the local emergency number.
Beyond Medicine: A Wider Public-Health Voice
Dr Siti Hasmah continued advocating for health and social causes after her government medical career. Her public work included family planning, adult literacy, drug-abuse prevention, mental health, disability support and the advancement of women.
She also held leadership roles in civic and humanitarian organisations and served as the inaugural chancellor of Multimedia University. These roles reflected a broad view of health—one shaped not only by clinical treatment, but also by education, opportunity and community support.
Her Connection to Singapore
Dr Siti Hasmah’s medical education began in Singapore at the King Edward VII College of Medicine, a predecessor of the NUS Yong Loo Lin School of Medicine. She met Dr Mahathir there as a fellow medical student, and the couple married in 1956.
Her 2018 NUS award recognised an alumnus whose medical education in Singapore went on to support public health across Malaysia. That shared history gives her legacy particular regional significance.
Remembering a Life of Service
Dr Siti Hasmah’s death marks the passing of a prominent Malaysian figure, but her legacy extends beyond public life. Her career shows how community medicine, prevention, health education and consistent access to care can improve outcomes across generations.
The respectful health lesson is not to draw conclusions about her longevity or cause of death. It is to remember the public-health priorities she championed: safer motherhood, healthier childhoods, preventive care and accessible health knowledge.
