Do Steroids Withdrawal Lead To Acute Adrenal Insufficiency?
Possibly
Detailed Answer:
I am very sorry to learn about this.
It is possible he experienced acute adrenal insufficiency due to steroid withdrawal. The abrupt stoppage of corticosteroid medications can potentially result in such a problem. This is particularly likely when a person has been on steroids for a prolonged length of time, such as several years.
As you seem to have clearly surmised, suddenly stopping prednisolone 15 mg maintenance dose that he had been on for 20 years , would likely have made him prone to developing acute adrenal insufficiency, especially when he was already in a stressful situation from the hospitalisation for ulcer/bleeding. Stress cover is typically initiated in these circumstances to prevent this complication from occuring.
