Brief Answer: You should never stop your treatment. During pregnancy, you should be followed carrefully by both the endocrinologist and the obstetrician. Detailed Answer: Hello, Thank you for using HCM. Your treatment consists on replacing the hormones which normally are produced by adrenal glands. After the adrenal glands are removed is caused a so called jatrogenic adrenal insufficiency, which is resolved by giving the hormones as a treatment by mouth , such as WYSOLONE and flouricot . So you should never interrupt your medication. Not only that , but you have to be careful with your health. If you note any change in your health such as your weight, appetite, blood pressure, sleep etc. you should do a series of laboratory exams such as sodium, potassium, glucose, BUN, Creatinine, ACTH, cortisol levels in blood and consult with an endocrinologist to see if you need any change in the dosage of your treatment or not. Regarding pregnancy, you should understand that the issue is not that you are ‘taking hormones’ or ‘using steroids’ in pregnancy but you are just replacing something your body is missing, not adding extra chemicals or un-natural substances to the body. On the other hand is obvious that the management of the disease during pregnancy, requires high caution and must be guided by both the endocrinologist and the obstetrician. Hope this is helpful.
