This overproduction of ACTH overstimulates the adrenal glands, leading to persistently high levels of cortisol, an essential-to-life stress hormone that affects metabolism, blood pressure and immune function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cushing\u2019s disease is a specific cause of <a href=\"https:\/\/glutenfreepleasure.com\/__proxy_domain\/themetabolicclinic.com.sg\/cushings-syndrome-excess-cortisol\/\" data-type=\"page\" data-id=\"97\">cushing\u2019s syndrome<\/a>. Cushing\u2019s syndrome refers to an overall state of excess cortisol in the body, which can arise from various causes, including cushing\u2019s disease, medications or adrenal tumours. Cushing\u2019s disease, however, refers specifically to the form caused by an ACTH-secreting pituitary adenoma, a benign tumour located at the base of the brain at the pituitary.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cortisol plays an essential role in regulating how the body responds to stress, maintains blood sugar and controls inflammation. It is essential to life. Without it, a drop of blood pressure and subsequently death occurs. Conversely when levels remain elevated for a long time, it can lead to a range of symptoms, including weight gain (particularly around the face and trunk), muscle weakness, high blood pressure and changes in mood or skin appearance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cushing\u2019s disease is rare and occurs more often in women than in men, typically between the ages of 20 and 50. With accurate diagnosis and effective treatment, cortisol levels can be normalised, allowing recovery of hormonal balance and improved quality of life.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/glutenfreepleasure.com\/__proxy_domain\/themetabolicclinic.com.sg\/wp-content\/uploads\/2026\/02\/image-1-1024x1024.jpeg\" alt=\"Cushing's Disease Singapore\" class=\"wp-image-905\" srcset=\"https:\/\/glutenfreepleasure.com\/__proxy_domain\/themetabolicclinic.com.sg\/wp-content\/uploads\/2026\/02\/image-1-1024x1024.jpeg 1024w, https:\/\/glutenfreepleasure.com\/__proxy_domain\/themetabolicclinic.com.sg\/wp-content\/uploads\/2026\/02\/image-1-300x300.jpeg 300w, https:\/\/glutenfreepleasure.com\/__proxy_domain\/themetabolicclinic.com.sg\/wp-content\/uploads\/2026\/02\/image-1-150x150.jpeg 150w, https:\/\/glutenfreepleasure.com\/__proxy_domain\/themetabolicclinic.com.sg\/wp-content\/uploads\/2026\/02\/image-1-768x768.jpeg 768w, https:\/\/glutenfreepleasure.com\/__proxy_domain\/themetabolicclinic.com.sg\/wp-content\/uploads\/2026\/02\/image-1.jpeg 1440w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Cushing\u2019s disease is a rare hormonal disorder caused by an ACTH-secreting pituitary tumour that leads to excessive cortisol production and widespread metabolic imbalance.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What causes Cushing\u2019s disease?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cushing\u2019s disease develops <a href=\"https:\/\/www.mskcc.org\/cancer-care\/types\/pituitary-tumors\/pituitary-adenomas\/acth-producing-tumors\" target=\"_blank\" rel=\"noreferrer noopener\">when a benign (non-cancerous) tumour<\/a> called a pituitary adenoma forms in the pituitary gland, located at the base of the brain.

Because many of its features overlap with common conditions such as obesity, diabetes, or depression, a structured diagnostic approach is essential.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Hormone testing&nbsp;<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Initial tests focus on confirming high cortisol levels and determining whether the excess is ACTH-dependent (pituitary-related). Common investigations include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>24-hour urinary free cortisol test<\/strong> \u2014 measures total cortisol production over a full day; elevated levels suggest hypercortisolism.<\/li>\n\n\n\n<li><strong>Late-night salivary cortisol test <\/strong>\u2014 cortisol should normally be low at night; persistently high levels indicate loss of normal hormonal rhythm.<\/li>\n\n\n\n<li><strong>Low-dose dexamethasone suppression test<\/strong> \u2014 in healthy individuals, <a href=\"https:\/\/www.ncbi.nlm.nih.gov\/books\/NBK542317\/\" target=\"_blank\" rel=\"noreferrer noopener\">cortisol levels fall after taking dexamethasone<\/a>.

Elevated ACTH points to a pituitary or ectopic (non-pituitary) source of cortisol overproduction.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Imaging studies<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Magnetic resonance imaging (MRI)<\/strong> of the pituitary gland is the preferred method for identifying ACTH-secreting adenomas.<\/li>\n\n\n\n<li>If the tumour is small or not clearly visible, <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC6526980\/\" target=\"_blank\" rel=\"noreferrer noopener\">inferior petrosal sinus sampling (IPSS)<\/a> may be performed. This advanced test measures ACTH levels directly from veins draining the pituitary gland, confirming the diagnosis of Cushing\u2019s disease and distinguishing it from other causes of Cushing\u2019s syndrome.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Additional evaluations<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Blood sugar, blood pressure, bone density and cholesterol levels are assessed to identify complications related to prolonged cortisol excess.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Accurate diagnosis is crucial before initiating treatment, as managing Cushing\u2019s disease differs from treating other forms of cortisol excess.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What are the treatment options for Cushing\u2019s disease in Singapore?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The goal of treatment is to normalise cortisol levels, remove or control the ACTH-secreting pituitary tumour and reverse the effects of prolonged hormone excess. Treatment is tailored to the tumour\u2019s size, location and the patient\u2019s overall health.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Surgery&nbsp;<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC4051420\/\" target=\"_blank\" rel=\"noreferrer noopener\">Transsphenoidal surgery<\/a> is the primary treatment for most patients. The pituitary tumour is accessed through the nasal passage and carefully removed without external incisions.<\/li>\n\n\n\n<li>This procedure can restore normal ACTH production and reduce cortisol levels to normal within days.<\/li>\n\n\n\n<li>Success rates are highest when the tumour is small (microadenoma).

Common options include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Adrenal-blocking agents <\/strong>such as ketoconazole, metyrapone or osilodrostat, which reduce cortisol production by the adrenal glands.<\/li>\n\n\n\n<li><strong>Pituitary-directed drugs<\/strong> such as pasireotide, which suppress ACTH secretion.<\/li>\n\n\n\n<li><strong>Glucocorticoid receptor antagonists<\/strong> like mifepristone, used in selected cases to block cortisol\u2019s effects on body tissues.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Radiotherapy&nbsp;<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Radiotherapy may be recommended if surgery cannot fully remove the tumour or if it recurs.<\/li>\n\n\n\n<li>Modern stereotactic techniques deliver precise doses to the pituitary gland while sparing surrounding structures.<\/li>\n\n\n\n<li>The effects of radiotherapy develop gradually over several months or years, so interim medical therapy is often needed.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Bilateral adrenalectomy&nbsp;<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In rare cases where cortisol levels remain uncontrolled after other treatments, <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC9467939\/\" target=\"_blank\" rel=\"noreferrer noopener\">removal of both adrenal glands<\/a> may be considered to eliminate cortisol production entirely.<\/li>\n\n\n\n<li>Lifelong hormone replacement is then required to maintain essential adrenal function.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Ongoing care and monitoring<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Regular follow-up is crucial, including blood tests to monitor cortisol levels, MRI scans to check for recurrence and assessment of bone, cardiovascular and metabolic health. Early detection of recurrence allows prompt re-treatment and prevents complications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With timely and effective management, most patients achieve long-term hormonal control and significant improvement in symptoms and quality of life.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Prognosis and long-term outlook for Cushing\u2019s disease<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">With appropriate treatment, most patients with Cushing\u2019s disease can achieve normal or near-normal cortisol levels and experience significant improvement in symptoms. However, recovery may take time, as the body adjusts after prolonged exposure to high cortisol levels.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>After successful treatment <\/strong>\u2014 when the ACTH-producing tumour is fully removed, cortisol levels often return to normal within days or weeks. Some patients may temporarily require cortisol replacement therapy until normal adrenal function resumes. Physical symptoms such as facial rounding, muscle weakness and high blood pressure gradually improve, while emotional well-being and energy levels also recover over time.<\/li>\n\n\n\n<li><strong>Recurrence and ongoing monitoring<\/strong> \u2014 even after successful surgery, recurrence can occur, sometimes years later. Lifelong follow-up with regular hormone testing and MRI scans is therefore essential. Early detection of relapse allows timely intervention and prevents complications.<\/li>\n\n\n\n<li><strong>Long-term health considerations<\/strong> \u2014some effects of prolonged cortisol exposure, such as osteoporosis, diabetes or cardiovascular disease may persist despite hormonal recovery. Targeted management of these conditions is an important part of ongoing care. Psychological support may also be beneficial, as mood and cognitive symptoms can take longer to resolve.<\/li>\n\n\n\n<li><strong>Outlook and quality of life <\/strong>\u2014 with early diagnosis, effective treatment and consistent follow-up, most patients can expect a good long-term prognosis. Advances in surgical techniques, medical therapy and imaging have significantly improved recovery rates and reduced the risk of complications.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Summary&nbsp;<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cushing\u2019s disease is a rare but serious hormonal disorder caused by an ACTH-producing tumour of the pituitary gland, leading to excessive cortisol production.
