KUALA LUMPUR, July 9 — Malaysia’s famously unpredictable weather—with its mix of sweltering heat, suffocating humidity, and sudden rainstorms—can be more than just an inconvenience.
This tropical climate presents unique health challenges that demand attention for individuals living with adrenal insufficiency. The extreme conditions can worsen dehydration and heat stress, making it harder for the body to function properly.
Dr Lim Chong Wei, consultant endocrinologist and diabetes and internal medicine specialist at Sunway Medical Centre shares his expert insights into how Malaysia’s weather impacts adrenal health and tackles the myths surrounding this often-misunderstood condition
Understanding The Adrenal Glands: The Body’s Hormonal Powerhouses
The adrenal glands, also called suprarenal glands, are small, triangular organs on top of each kidney.
“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,” Dr Lim explained.
Adrenal insufficiency occurs when the adrenal glands cannot produce enough hormones, which are essential for maintaining blood pressure, regulating metabolism and managing stress.
“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.
“However, other environmental factors like tuberculosis (TB), human immunodeficiency virus (HIV) and fungal infection may contribute to this condition in any age group,” said Dr Lim.
How Malaysia’s Weather Complicates Adrenal Health
With its relentless heat and humidity, Malaysia’s tropical climate can make identifying adrenal disorders more challenging.
Symptoms such as dehydration, fatigue, and poor concentration can easily be mistaken for the effects of environmental stress rather than a serious underlying condition.
“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,” according to Dr Lim.
He emphasises the importance of seeking medical advice and undergoing proper testing for individuals experiencing persistent symptoms to ensure timely diagnosis and effective management.
How Do Individuals Diagnose Adrenal Disorders?
Adrenal disorders are notoriously tricky to diagnose because their symptoms overlap with those of other health issues.
A key diagnostic tool is the Short Synacthen Test, which evaluates how well the adrenal glands respond to stimulation.
“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,” Dr Lim explained.
Managing Adrenal Disorder in Malaysia’s Climate
While adrenal disorders cannot be cured, they can be effectively managed. Staying hydrated is especially crucial in Malaysia’s humid environment, where dehydration can exacerbate symptoms.
Dr Lim advises individuals to keep themselves well-hydrated and to drink water whenever they feel thirsty.
“Ideally, everyone should carry a bottle of water with them and ensure they stay hydrated, especially in hot and humid conditions,” he recommended.
“Without treatment, adrenal insufficiency can lead to life-threatening adrenal crises, where the body’s inability to produce sufficient hormones, resulting 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.”
Debunking Common Misconceptions About Adrenal Disorders
Adrenal disorders are often misunderstood, leading to myths that can hinder proper management and treatment.
One common misconception is that adrenal function can recover 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,” Dr. Lim clarified,
Another myth is that hydrocortisone, a critical medication for adrenal insufficiency, is merely a supplement.
“Hydrocortisone is not a simple supplement,” Dr Lim emphasised. “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 health care provider.”
