How Malaysia's heat affects people with adrenal insufficiency

How Malaysia's heat affects people with adrenal insufficiency

Sinar Daily13-07-2025
Malaysia's tropical climate, marked by scorching heat, relentless humidity and sudden downpours, is more than just uncomfortable.
For individuals living with adrenal insufficiency, these environmental extremes can severely impact their health, intensifying risks like dehydration and heat stress that strain the body's ability to function normally.
Sunway Medical Centre Consultant Endocrinologist and Diabetes and Internal Medicine Specialist Dr Lim Chong Wei explains on how Malaysia's weather patterns can complicate adrenal disorders and debunks common myths about this often-overlooked condition.
Often referred to as the body's hormonal control centres, the adrenal glands sit atop each kidney and are responsible for producing key hormones.
As Dr Lim explains, these hormones regulate vital functions such as blood pressure and the body's stress response which are essential to overall health.
'The adrenal glands produce essential hormones like cortisol, noradrenaline and adrenaline, which play a vital role in maintaining blood pressure within a healthy range. When the body lacks sufficient cortisol, an individual's blood pressure may drop," he said in a statement.
Adrenal insufficiency, he says, arises when these glands fail to produce enough of these critical hormones.
"The condition commonly affects people between the ages of 30 and 50, and it is usually associated with autoimmune conditions like type one diabetes, coeliac and thyroid disorder," he added.
However, he noted that other environmental factors like tuberculosis (TB), human immunodeficiency virus (HIV) and fungal infection may contribute to this condition in any age group.
Malaysia's hot and humid weather doesn't just cause discomfort, it also makes diagnosing adrenal insufficiency more difficult.
Many symptoms, such as exhaustion and poor focus, can easily be mistaken for common side effects of heat or stress.
Dr Lim notes that this overlap complicates early detection.
"Environmental stressors, including dehydration and poor concentration, often mask the symptoms of adrenal insufficiency.
"Compounding this challenge, the symptoms of adrenal insufficiency are non-specific and include weight loss, nausea, vomiting, abdominal discomfort, fatigue and confusion, making it difficult to distinguish between general fatigue and a more serious underlying adrenal issue," he said.
He stressed that persistent symptoms should not be ignored, urging individuals to consult medical professionals for proper assessment and testing.

How do individuals diagnose Adrenal Disorders?
According to Dr Lim, adrenal disorders can be difficult to pinpoint without specific testing because their symptoms overlap with those of other health issues.
One of the key diagnostic tools used is the Short Synacthen Test. Dr Lim further explained on how this test works to confirm adrenal function.
"This test involves administering synthetic ACTH to stimulate the adrenal glands. The adrenal glands fail to produce adequate cortisol in response to this stimulation for those with adrenal insufficiency," he said.
While adrenal disorders aren't curable, Dr Lim said they can be managed, especially with a focus on hydration, which becomes even more important in a hot and humid environment like Malaysia.
"Ideally, everyone should carry a bottle of water with them and ensure they stay hydrated, especially in hot and humid conditions,' he recommended.
He also warns about the seriousness of untreated adrenal insufficiency, which can lead to an adrenal crisis, a potentially fatal emergency.
'Without treatment, adrenal insufficiency can lead to life-threatening adrenal crises, where the body's inability to produce sufficient hormones results in fatal outcomes.
"It will then become a medical emergency, and patients would require urgent hydrocortisone. Patients may be in a comatose state, and without treatment, up to 20 per cent of people in shock may die from an adrenal crisis," he said.
Clearing the air on misconceptions
Myths surrounding adrenal disorders can prevent people from seeking or following through with the right treatment.
One widespread misconception is that adrenal function can return after a diagnosis of primary adrenal failure.
"Primary adrenal failure is irreversible, and the adrenal glands do not regain their ability to produce hormones.
"However, in cases of secondary adrenal insufficiency, there is a small chance about one in six that adrenal function may recover, which can take up to five years," he noted.
According to Dr Lim, another dangerous myth is treating hydrocortisone as just another over-the-counter supplement.
'Hydrocortisone is not a simple supplement. It is a life-saving medication that replaces the hormones the body can no longer produce, essential for regulating blood pressure and responding to stress. Patients should never discontinue its use without consulting their healthcare provider," he said.

French left urges Macron to stop US contraceptive destruction

PARIS: France's left-wing politicians on Saturday called on President Emmanuel Macron to intervene over US plans to destroy nearly $10 million worth of female contraceptives in Europe, calling it an 'affront' to public health. A State Department spokesperson told AFP this week that 'a preliminary decision was made to destroy certain' birth control products from 'terminated Biden-era USAID contracts.' The US Agency for International Development, the country's foreign aid arm, was dismantled by Donald Trump's administration when he returned to office in January, replacing former president Joe Biden. Under the plan, some $9.7 million worth of implant and IUD contraceptives stored in Belgium are reportedly set to be incinerated in France. An open letter signed by French Green leader Marine Tondelier and several female lawmakers called the US decision 'an affront to the fundamental principles of solidarity, public health and sexual and reproductive rights that France is committed to defending.' In the letter, they urged the French president 'not to be complicit, even indirectly, in retrograde policies,' saying women's contraception products such as IUDs and implants were intended for 'low- and middle-income countries.' 'Cutting aid for contraception is shameful, destroying products that have already been manufactured and financed is even more mind-boggling,' Tondelier told AFP. The Greens urged Macron to request the suspension of the plan 'as part of a joint initiative with the European Commission.' They also called on him to back humanitarian organisations that say they are ready to redistribute the contraception products. Separately, Mathilde Panot, parliamentary leader of the hard left France Unbowed (LFI) party, also urged Macron and Prime Minister Francois Bayrou to take action. 'You have a responsibility to act to prevent this destruction, which will cost lives,' she said on X. 'These resources are vital, particularly for the 218 million women who do not have access to contraceptive care.' The US plan has sparked outrage from global health NGOs, with Doctors Without Borders denouncing the 'callous waste.' 'It is unconscionable to think of these health products being burned when the demand for them globally is so great,' said Rachel Milkovich of the medical charity's US office. The State Department spokesperson said the destruction will cost $167,000 and 'no HIV medications or condoms are being destroyed.' Doctors Without Borders says that other organisations have offered to cover the shipping and distribution costs of the supplies, but the US government declined to sign off. US lawmakers have approved slashing some $9 billion in aid primarily destined for foreign countries. - AFP

Discrimination of high-risk communities hinders HIV prevention efforts, say NGOs

Last Saturday, Kelantan police chief Yusoff Mamat said more than 20 men were arrested at a bungalow in Kota Bharu, allegedly for attending a 'gay party'. PETALING JAYA : Discrimination against high-risk communities will hinder HIV prevention efforts, says a coalition of NGOs, following the recent raid on a sexual health event in Kelantan. The Federation of Reproductive Health Associations Malaysia (FRHAM) said the marginalisation and societal disadvantages faced by such communities make outreach challenging. While it lauded the health ministry for reducing the number of new HIV cases through the national Needle and Syringe Exchange Programme, it said the epidemic has since shifted to sexual contact as a primary mode of transmission within the last decade. 'This necessitates a change of focus to effective prevention services,' said the federation's acting chairman, Dr Annuar Husainy Hussein. 'HIV prevention services include testing, treatment and safer sex practices, as well as the use of HIV medication. 'These services are essential public health initiatives, especially for populations at increased risk of HIV, including men who have sex with men, transgender persons, people who inject drugs and sex workers. 'FRHAM takes the stand that the harassment and persecution of the affected communities must cease, and that experts in the field be granted the necessary space to accomplish their work.' Last Saturday, Kelantan police chief Yusoff Mamat said more than 20 men were arrested at a bungalow in Kota Bharu, allegedly for attending a 'gay party'. However, several groups and doctors later clarified that it was a health event organised to provide sexual health and HIV-related information, condoms, and voluntary testing to promote safer sexual health practices. They said the event included talks by healthcare providers, including doctors. It was to have ended by midnight, but about 20 attendees were still at the event awaiting their test results.

Vilified by Kelantan cops as ‘gay party', here's what actually happens during an HIV outreach and why it's important

A June HIV outreach event in Kota Bharu provided HIV/STI screenings, counselling, health talks, and meals for 70 participants, ending late to accommodate those with work commitments. However, Kelantan police raided the outreach around 1am, labelling it a 'gay sex party'; three men were later fined for possessing obscene content, though no sexual activity or drug use was found. Civil society groups condemned the raid's misinformation and stigmatising impact, warning it could deter vulnerable communities from accessing vital HIV prevention services. KOTA BHARU, July 26 — Kelantan police were lambasted last week after accusing an HIV health outreach programme here in June as a 'gay sex party', with the Malaysian AIDS Council (MAC) and other civil societies forced to correct the misinformation. Despite that, three men arrested by the police during the event had already been charged in court with possessing 'obscene' images and videos on their phones — and were subsequently fined after pleading guilty. In a statement last week, the MAC explained that the event was part of a long-term health outreach initiative organised by the local NGO Kelantan Patient Intermediary Association (Sahabat) under the Malaysian AIDS Foundation (MAF) to promote HIV interventions among hard-to-reach populations. The MAC said the session was held in collaboration with Kota Jembal Health Clinic, and is a part of the Differentiated HIV Services for Key Populations (DHSKP) model introduced by the Health Ministry (MOH) to combat AIDS by 2030. Malay Mail unpacks the event and why it is essential: Kelantan State Health Director Datuk Dr Zaini Hussin has denied that it is the organiser of the HIV outreach programme raided by police. — Picture from Facebook/Jabatan Kesihatan Kelantan What is DHSKP anyway? Health Minister Datuk Seri Dzulkefly Ahmad last week confirmed on X that the event was part of ongoing outreach efforts. As outlined by the MAC, the DHSKP is a strategic, community-driven initiative aimed at tailoring HIV services to the unique needs of populations most at risk. These key populations include men who have sex with men, transgender individuals, people who inject drugs, and female sex workers or women at risk. This model relies on collaborations between community organisations and government clinics, positioning community healthcare workers as pivotal in connecting people at risk to essential prevention, testing, treatment, and care services. Such efforts aim to make healthcare more inclusive, accessible, and effective, especially for those facing discrimination within traditional healthcare settings. SalamMadani Colloboration bet MOH, State Health Depart JKN) & health NGO groups, is of great importance in reaching out to high-risk populations in order to impart knowledge about prevention strategies, the importance of early diagnosis & benefits of early treatment in… — Dzulkefly Ahmad (@DrDzul) July 21, 2025 'With the current shift in HIV transmission trends toward sexual contact, intervention strategies have been adapted to respond to emerging needs,' Sahabat said in a statement yesterday. 'Efforts are now focused on reaching individuals engaged in high-risk sexual behaviour, a group often difficult to access through conventional health services. All interventions are carried out with sensitivity to local cultural norms and values.' Sahabat explained it has been a key implementing partner in HIV prevention programmes for high-risk communities in Kelantan, working in close collaboration with the MOH, MAC, and the Kelantan Health Department — even as the latter previously tried to distance itself from the event. 'This long-standing partnership has played a significant role in reducing new HIV infections in the state — particularly among people who inject drugs, once the primary driver of local HIV transmission,' it said. Sahabat said the event was simply intended to offer a safe, stigma-free environment for delivering essential health information. — Picture courtesy of Sahabat What actually happened that night of the raid? Sahabat said it had organised a community outreach programme at a homestay here on June 17, when the police raided the event while claiming it was a 'gay sex party' event. Kelantan police chief Datuk Mohd Yusoff Mamat insisted they had acted due to complaints and cited valid intelligence in justifying its raid — arguing it was done to maintain public order and safeguard moral values. However, Sahabat said the event were merely aimed to provide a safe, stigma-free space to deliver vital health information, screening services, and counselling to members of the key populations. According to Sabahat: A total of 62 individuals attended the event, including 13 Sahabat staff members, in addition to a Family Medicine Specialist and a Medical Officer who served as guest speakers. The session began with a health talk on HIV and sexually transmitted infections (STIs), followed by an interactive quiz and a communal meal. Those who tested positive were referred to MOH facilities for confirmatory testing and follow-up treatment. Four participants living with HIV also attended with their own antiretroviral medication. No medication was dispensed or distributed at the event. The event concluded at approximately 11:30 p.m., with around 20 individuals, including seven Sahabat staff, staying behind to complete follow-up screening in phases. 'The programme was conducted outside regular office hours to allow working participants to attend and benefit from the services offered,' an MAC spokesman told Malay Mail. 'Each individual screening took between 10 and 15 minutes. In total, the session extended to nearly six hours — well past midnight — to ensure that all 70 clients received both testing and appropriate counselling.' Kelantan health director Datuk Dr Zaini Hussin previously said he was informed that the raid had happened well after the outreach programmed ended. MAC and Sahabat maintained that the raid happened around 1am, when screenings were still conducted. Kelantan Police Chief Datuk Mohd Yusoff Mamat said their intention behind the raid was simply to undertake 'amar makruf' (enjoining good) and 'nahi mungkar' (forbidding the bad). — Bernama pic What has the reaction been so far? The raid has prompted a coalition of 31 NGOs and civil entities led by transgender advocacy group Justice for Sisters (JFS) to release a statement urging Kelantan police to correct their portrayal of the June event. The coalition said all attendees tested negative in police-conducted urine tests, and no evidence of sexual activity or promotional content on social media was found. The coalition said the police's public statements were stigmatising, including unnecessary disclosure of HIV status and harmful suggestions about HIV medication. They also alleged human rights violations during the raid, including degrading treatment and privacy breaches, which have deterred victims from seeking redress. JFS co-founder S. Thilaga told Malay Mail that due to Malaysia's legal environment, these programs cannot be openly promoted, making it crucial for NGOs supported by the MOH to conduct targeted outreach efforts. Thilaga warned that labelling the event as a 'gay party' could incite moral panic among LGBTQ and vulnerable communities. 'Following the raid, there's heightened fear and concern for safety,' she said, adding that such actions might undermine trust between these communities and service providers. Citing a MOH report, Thilaga said conducting HIV outreach is challenging for the LGBTQ groups due to existing discrimination. 'This issue may further deter vulnerable groups from seeking services,' she added. Justice for Sisters co-founder S. Thilaga warned that the raid has only made the LGBTQ community more afraid of getting health services. — Picture by Hari Anggara. Echoing similar sentiments, PT Foundation acting chief operating officer Raymond Tai expressed concern over the incident's impact on the collaborative programmes between the Health Ministry and NGOs. 'The controversy jeopardises the programme's future, which is pivotal for our 2030 target,' he said, stressing that continued efforts are vital for success. Tai said Malaysia is an exemplary country that uses government and NGO partnership to mitigate HIV/AIDS to end it in 2030. Following the controversial police raid, JFS said it conducted a survey among vulnerable communities, receiving responses from 93 from the lesbian, gay, bisexual, transgender, and queer (LGBTQ) community and 13 from outside the community. The findings revealed some concerns within the LGBTQ community:
