I have a question that is specific to a GI specialist...For a year my 19 year old son has been dealing with IBS mixed D/C as well as GERD which is the more bothersome of the 2 as it has caused a feeling of phlegm and/or lump in his throat. For the IBS, He follows the FODMAP recommendations for his diet and it has helped the IBS. He takes Align daily and Protonix 40mg daily. The reflux symptoms are worsening now despite taking Protonix. He has been tested for Celiac, and H Pylori. He has had an endoscopy which was normal. All blood tests have been normal.What more can we be asking his doctor and/or what more can we do to improve his symptoms or better yet cure whatever is causing all this?

Dear Doctors, I am a first year international biology student.

Dear Doctors,I am a first year international biology student. I have a question, what I amtrying to figure out. If anyone could help me understand this I would greatlyappreciate it.Question1: Metyrapone testNormally the metyrapone test will cause the deoxycortisol levels to rise, butin cases of Cushing's syndrome they may not. What does this failure to respond inthe metyrapone test indicate about ACTH secretion and what might cause thisThank you.Sincerely,Evafailure?Question 2: Dexamethasone Suppression test:I know that in patients suffering from depression very often the low dose treatment has no effect, while the high dose suppresses cortisol secretion. In some, but not all forms of Cushing's syndrome, both low and high dose of treatments fail to bring cortisol down. But, what do these varying response patterns tell me about what is happening to control of the adrenal in these different disease states, and why do some Cushion's syndrome patients respond to high dose of dexamethasone, but others do not?

I do CMEs for my License and read on the Thyroid sometimes

I do CMEs for my License and read on the Thyroid sometimes for updates. What is the % of those left untreated for FTC who don't die? Can I beat the weirdo symptoms w/o seeing a heme/onc or another endocrine doctor? My TSH was 3.1, my ANA was +, my CRP was +, my RH Factor was -, my SLE was +, my Pancytopenia is +, my D-Dimor is down to .35 from .51, I have a ton of junk going on and hate that my ENT missed the positive report of FTC due to lack of insurance at the time. So, what's my prognosis w/ feeling of being strangled tonight plus all the other stuff I mentioned last time??

a neurologist has told my husband that he thinks he has alzhimers.

a neurologist has told my husband that he thinks he has alzhimers. we thought the tremors of his right arm and hand may be the result of a pinched nerve resulting from a fall. there has been no testing done yet, this was just the result of an office visit. they want to schedule him for an mri - should we wait for the results of the mri before we decide or do we take him at his word and prepare for the worst (alzhimers)? are we putting too much faith in a neurologist, or do we assume since he is a neurologist that he knows what he is talking about
