Addison's Disease and Cosmetic Surgery: Stress-Dose Steroids, Adrenal Crisis, Nausea, Fluids, and the Darkened Scar Question

She is 38, and she was diagnosed with Addison's disease at 31, in an emergency department, after three days of vomiting turned into a blood pressure the nurses could barely find. Her sodium was low, her potassium was high, and an endocrinologist who saw her the next morning asked a question nobody else had: how long had her skin been this dark? The answer was about a year. Her knuckles, her elbows, the creases of her palms, and the cesarean scar from her second child had all deepened to a shade that did not match the rest of her. Seven years later she takes hydrocortisone three times a day and fludrocortisone every morning, carries an emergency injection in her bag, and feels well. She books a consultation for a tummy tuck and a breast lift. The intake form asks whether she takes steroids. She writes "hydrocortisone." The coordinator notes "low dose steroid, fine." Nobody asks where her injection kit is, or what happens if she vomits the night after surgery.

That gap is the subject of this piece. Addison's disease and cosmetic surgery are compatible. People with well-treated adrenal insufficiency have elective operations safely every day. But the condition is one of the few in which a routine missed step, a skipped dose on a fasting morning, a bout of postoperative vomiting at home, can become life-threatening within hours. Every part of the plan has to be built around a gland that no longer answers when the body calls for it.

Addison's disease and cosmetic surgery: what the diagnosis actually changes

The short answer: Addison's disease means the adrenal glands no longer make enough cortisol (and usually aldosterone), so the body cannot mount its normal hormonal response to the stress of surgery, and that response has to be supplied deliberately, on a written schedule, before, during, and after any operation that involves anesthesia.

Addison's disease is primary adrenal insufficiency: the problem sits in the adrenal glands themselves. In wealthy countries, the large majority of cases are autoimmune, with the immune system gradually destroying the adrenal cortex. Tuberculosis was historically the leading cause and still is in parts of the world. Other causes include infections, bleeding into the glands, certain cancers and medications, surgical removal of both adrenals, and congenital adrenal hyperplasia, an inherited enzyme disorder that also produces adrenal insufficiency and is managed with the same surgical precautions. It is rare, affecting on the order of 1 to 2 people per 10,000 in published European estimates.

The distinction between types matters for surgery and for skin:

• Primary adrenal insufficiency (Addison's disease) loses both cortisol and aldosterone. The pituitary gland senses low cortisol and pumps out more ACTH, the hormone that normally stimulates the adrenals. Persistently high ACTH darkens the skin.
• Secondary adrenal insufficiency comes from the pituitary not making enough ACTH. Cortisol is low, aldosterone is usually preserved, and the skin does not darken.
• Steroid-induced adrenal suppression happens when months of prednisone, inhaled steroids, or repeated injections shut down the body's own production. These patients have their own perioperative rules, covered in the piece on cosmetic surgery with autoimmune disease, and those rules are different from the ones that apply to Addison's disease.

That last point is the source of a lot of confusion. For decades, anyone on steroids got large "stress doses" before surgery. More recent guidance from the American College of Rheumatology and the American Association of Hip and Knee Surgeons moved away from that for patients taking chronic steroids for rheumatic disease, recommending that they simply continue their usual daily dose. That guidance explicitly does not apply to people with primary adrenal insufficiency or pituitary disease. A practice that has absorbed the newer "no stress dose" message for rheumatology patients and applies it to a patient with Addison's disease has made exactly the wrong generalization.

The other thing the diagnosis brings is company. Autoimmune Addison's disease often travels with other autoimmune conditions, in a cluster called autoimmune polyendocrine syndrome type 2. The most common partners are autoimmune thyroid disease and type 1 diabetes, with vitiligo, celiac disease, pernicious anemia, and early ovarian failure appearing less often. Each of those has its own surgical implications. The piece on thyroid disease before cosmetic surgery and the piece on vitiligo and cosmetic surgery apply directly to many patients with Addison's disease.

Stress-dose steroids: the plan that has to exist before the day of surgery

The short answer: for any operation under general anesthesia, sedation for a substantial procedure, or regional anesthesia, a person with Addison's disease should receive intravenous hydrocortisone at the start, continued coverage while fasting or stressed, and a stepped return to their usual oral doses, all written down and agreed with the endocrinologist before the date is set.

A healthy adrenal gland responds to surgery by multiplying its cortisol output, sometimes several times over, for a day or more. That surge supports blood pressure, blood sugar, and the vascular response to anesthesia and blood loss. A person with Addison's disease cannot produce it. Without replacement, the result can be adrenal crisis: low blood pressure that does not respond to the usual drugs, vomiting, abdominal pain, confusion, low sodium, high potassium, and low blood sugar. Adrenal crisis occurs in a meaningful minority of patients with adrenal insufficiency every year, even outside surgery, and it still kills people.

The most detailed modern guidance comes from a 2020 joint guideline from the UK Association of Anaesthetists, the Royal College of Physicians, and the Society for Endocrinology, consistent with the Endocrine Society's clinical practice guideline on primary adrenal insufficiency. The shape of that guidance, which the endocrinologist and anesthesiologist then tailor, looks like this:

• Surgery under general or regional anesthesia: intravenous hydrocortisone given at induction (100 mg is the dose most guidelines cite), then continued high-dose coverage, either as a continuous infusion or regular injections, for as long as the patient is fasting or physiologically stressed.
• After surgery: once eating and drinking normally, a doubled oral dose for roughly 48 hours after uncomplicated procedures, and longer after major operations or any complication, before returning to the usual dose.
• Minor procedures under local anesthesia: often nothing beyond the usual dose, or a doubled dose that day. This should still be decided in advance, not on the morning of the procedure.
• Fludrocortisone: commonly paused while hydrocortisone doses are high (high-dose hydrocortisone has enough mineralocorticoid effect to cover it), then resumed when doses return to normal. The endocrinologist should say so explicitly.

Two practical details trip up otherwise careful plans. The first is the fasting morning. Patients are told "nothing by mouth after midnight" and some hear that as "skip your morning pills." The morning hydrocortisone dose should be taken with a sip of water unless the anesthesia team has said otherwise in writing. Scheduling a patient with Addison's disease as the first case of the day shortens the fasting period and lowers the stakes of any delay.

The second is the anti-nausea dose of dexamethasone. Anesthesiologists routinely give a single dose of dexamethasone to prevent postoperative nausea, and the piece on nausea after cosmetic surgery explains why. Dexamethasone is a powerful glucocorticoid, but it has essentially no salt-retaining effect and it is not a substitute for planned hydrocortisone coverage. It is an anti-nausea measure, not the stress-dose plan. The piece on steroids for swelling after plastic surgery covers the separate question of steroid courses for swelling, which should also be run past the endocrinologist rather than stacked on top of replacement without a plan.

"The operation is the part everyone plans. The adrenal plan, the one that has to work at 2 a.m. on the second night at home, is the part that decides whether the recovery is uneventful."

Anesthesia, fluids, nausea, and the first nights at home

The short answer: the riskiest windows for a person with Addison's disease are not usually in the operating room, where intravenous hydrocortisone and close monitoring are available, but in the hours and days afterward, when vomiting, dehydration, fever, or a missed dose can tip a patient into crisis away from anyone who knows the diagnosis.

In the operating room, the main signals are blood pressure and fluid balance. Low blood pressure that responds poorly to fluids and vasopressors is the classic warning sign of inadequate cortisol, and a good anesthesiologist treats it with hydrocortisone first and diagnostics second. Because aldosterone is missing, salt and water handling are also impaired, so preoperative blood tests should include sodium, potassium, and glucose, and the intravenous fluid plan should favor salt-containing solutions over large volumes of dilute fluid. The piece on anesthesia choice and the operative plan covers the general questions; the Addison's-specific ones are about steroid coverage, fluids, and where the patient recovers.

That last question deserves a direct answer. For anything beyond a short procedure under local anesthesia, a person with Addison's disease should have surgery where intravenous hydrocortisone is stocked, where the anesthesia provider has managed adrenal insufficiency before, and where an overnight stay is available if nausea, low blood pressure, or pain control does not go as planned. That is often a hospital or a hospital-affiliated surgery center rather than a small office suite. The piece on outpatient facility accreditation and the piece on hospital privileges explain what those credentials actually guarantee. Operations abroad, with a return flight days later and no local endocrinologist, carry specific added risk for this condition; the piece on plastic surgery tourism covers the general problem.

At home, the rules come from the "sick day" framework every person with Addison's disease should already know:

• Fever, significant pain, or illness requiring bed rest: the oral hydrocortisone dose is typically doubled until it resolves. A postoperative fever counts.
• Vomiting or severe diarrhea: oral tablets cannot be relied on. If a dose cannot be kept down, the emergency intramuscular hydrocortisone injection is used and the patient goes to an emergency department, stating the diagnosis immediately.
• Feeling faint, confused, or unable to keep fluids down: treat as possible adrenal crisis, not as "normal recovery."

That means the caregiver matters more than usual. The person staying with the patient for the first nights should know the diagnosis, know where the injection kit is, know how to give it, and know that the wrong move is to wait until morning to see if the vomiting settles. The piece on the recovery house and the first 72 hours covers caregiver planning in general; for this condition, a written one-page instruction sheet, taped to the refrigerator, is reasonable. Patients should also wear a medical alert bracelet or carry a steroid emergency card, and the surgical team's discharge paperwork should state the diagnosis in plain language for any emergency department that sees the patient later.

Pain control intersects too. Opioids cause nausea and constipation, and nausea is the enemy here. A plan that leans on long-acting local anesthetic, acetaminophen, and anti-inflammatories where appropriate, as described in the piece on opioid-sparing recovery, lowers the chance of the vomiting that turns a routine recovery into an emergency visit. Patients who also have POTS-like lightheadedness from under-replaced fludrocortisone will recognize some overlap with the advice in the piece on POTS and cosmetic surgery: hydration, salt, and slow position changes all help.

Darkened scars, knuckles, and areolas: what the pigment means and what to do about it

The short answer: the skin darkening of Addison's disease is driven by high ACTH, so it usually fades over months once replacement is adequate, but scars that formed while ACTH was high can stay dark permanently, and no laser or cream will hold its result if the underlying hormone level is still elevated.

ACTH comes from a larger precursor molecule that also produces melanocyte-stimulating hormone, and ACTH itself can stimulate the pigment cells in the skin. When the pituitary drives ACTH up to compensate for failing adrenals, pigment increases. The darkening tends to show first in areas of friction and folding: the creases of the palms, the knuckles, the elbows and knees, the lips and gums, the nipples and areolas, bra-strap and waistband lines, and freckles and moles. It also shows in scars.

That scar detail matters to plastic surgeons. A scar that matured while ACTH was high, before diagnosis or during a period of under-treatment, often darkens and can stay dark even after treatment brings ACTH down. Scars formed after replacement is well established generally behave like anyone else's scars. That has three practical consequences:

• Old dark scars may not lighten on their own. A cesarean scar or an appendix scar from the undiagnosed years may be the most visible reminder of the disease. Revision, camouflage, or careful laser work are reasonable options once the skin is stable. The piece on scar camouflage and medical tattooing and the piece on scar care after plastic surgery cover the tools.
• New scars depend on control. A patient whose replacement is adequate before surgery has the strongest chance of a scar that matures to a normal shade. Darkening of a new scar, or of the knuckles and gums, in the months after surgery is a signal to check replacement with the endocrinologist, not just to start a bleaching cream.
• Treating pigment against a high ACTH is a losing battle. Hydroquinone, peels, and pigment lasers can lighten the skin temporarily, but if ACTH is still elevated, the pigment returns. Worse, aggressive resurfacing on darker, stimulated skin increases the risk of post-inflammatory hyperpigmentation.

The general guidance on pigment treatment still applies once the hormone side is settled. The piece on lasers for sun spots and pigmentation, the melasma piece, and the piece on ablative versus non-ablative resurfacing all describe a conservative, test-spot-first approach that suits this situation. Darkening around the eyes or in skin folds can also have other causes, and the piece on under-eye dark circles and the piece on acanthosis nigricans are useful for telling them apart.

One more nuance: new, unexplained darkening of the skin in someone without a diagnosis deserves a medical evaluation before cosmetic treatment. Undiagnosed Addison's disease has been found in patients who first sought help for a tan that would not fade. A dermatologist or aesthetic provider who notices darkening of the gums, palm creases, and a recent scar, along with fatigue, weight loss, salt craving, or lightheadedness, should send the patient for blood tests rather than for a peel.

Procedure by procedure: tummy tuck, liposuction, breast surgery, the face, and injectables

The short answer: the operations themselves are the same ones anyone would have, but longer, larger, and combined procedures demand fuller steroid coverage and more careful fluid planning, while injectables and small procedures under local anesthesia usually need little or no change beyond the usual dose.

Tummy tuck and combined body procedures. A full abdominoplasty, especially combined with liposuction or breast surgery in a single session, counts as major surgery for steroid-planning purposes. Longer operating time, larger fluid shifts, and more postoperative pain all increase the cortisol demand. Many surgeons prefer to stage large combinations in patients with adrenal insufficiency rather than doing everything at once, and the reasoning in the piece on mommy makeover timing applies with extra weight here. An overnight stay after a combined procedure is a reasonable default rather than a luxury.

Liposuction. Tumescent liposuction moves a lot of fluid in and out of the body, and a patient without aldosterone handles salt and water less predictably. Large-volume liposuction should be planned with the endocrinologist's input on fludrocortisone and fluids, and with attention to the lidocaine limits described in the piece on lidocaine toxicity in tumescent liposuction. Some patients with poorly controlled disease are also unusually thin, which limits donor fat for fat grafting.

Breast surgery. Breast reduction, lifts, and augmentation are not affected by the diagnosis in technique, but areolar and scar pigment are. A patient whose areolas darkened during the undiagnosed years may ask whether a lift or reduction will lighten them. It will not. Areola size can be reduced, but color is a function of the hormonal history and the individual skin. The piece on breast reduction surgery covers scar patterns, which matter because a periareolar and vertical scar will be visible against darker surrounding skin if replacement slips during healing.

Facial surgery. Facelifts, eyelid surgery, and rhinoplasty follow the same steroid rules as any general anesthetic. A facelift under sedation is still a substantial operation, and "it's only twilight anesthesia" is not a reason to skip coverage. Gum and lip pigment does not change with facial surgery, which is worth knowing before a lip lift or a smile-focused procedure.

Injectables and minor procedures. Botox, filler, and small procedures under local anesthesia usually need no extra steroid, as the piece on combining Botox and filler in one visit illustrates for routine treatments. The exceptions are rare complications. A filler vascular occlusion or a significant infection is a physiological stress, and the sick day rules apply.

The overlap with other conditions. Patients whose Addison's disease is part of a broader autoimmune picture, or who also have conditions like inflammatory bowel disease or myasthenia gravis that are treated with steroids, need a single coordinated plan rather than a stack of separate ones. The Crohn's and ulcerative colitis piece and the myasthenia gravis piece both describe steroid layering that becomes more complex when adrenal insufficiency is added. And for anyone whose adrenal insufficiency followed cancer treatment, particularly immunotherapy, the piece on cosmetic surgery after chemotherapy covers the other timing questions.

A final timing rule ties these together. Elective surgery should wait until replacement has been stable for several months: no recent crisis, no recent dose changes, normal sodium and potassium, stable blood pressure, and an endocrinologist who agrees the patient is in a steady state. A recent emergency admission is a reason to postpone, not a footnote. If a practice resists that pause, the piece on getting a second consultation applies.

The honest summary

Addison's disease is not a reason to avoid cosmetic surgery. People with well-treated primary adrenal insufficiency can have tummy tucks, breast lifts, liposuction, and facial surgery with outcomes comparable to anyone else, provided the plan supplies what their adrenal glands cannot.

That plan is specific. Intravenous hydrocortisone at the start of any operation under general or regional anesthesia, continued coverage while fasting or stressed, a doubled oral dose for days afterward, and a written decision about fludrocortisone. The morning dose taken on the morning of surgery. A first-case slot. A facility that stocks intravenous hydrocortisone and can keep the patient overnight. A nausea strategy that does not mistake one dose of dexamethasone for adrenal coverage. A caregiver who knows the sick day rules and where the emergency injection is. And a clear understanding that the newer "no stress dose" guidance for rheumatology patients does not apply here.

On the cosmetic side, the darkened knuckles, gums, areolas, and scars of Addison's disease are a hormonal signal first and a skin problem second. Old scars from the undiagnosed years may need revision or camouflage. New pigment usually means the replacement needs adjusting, not that the patient needs a stronger cream.

A practice that hears "hydrocortisone" and writes "low dose steroid, fine" has not understood the diagnosis. The right practice will ask for the endocrinologist's letter before it asks for the deposit, and will plan the night after surgery as carefully as the operation itself.
