Stomach bloating from Decadron?

[hope]

Hi all, Well I just got new a new sypmtom. Somatach fullness and distention. I called onc on calll today about this. He thinks it might be due to decradron retaining water in stomach. Has anyone heard of this? I am taking only 2mg of Decadron per day for brain mets and radiation pneumonitis. I am also taking potassium and phosporus because my levels have been low. Have any of you experienced these symptops while on decadron, potassium or phosporus. I have to call my regular onc on Monday to see what she says. I am getting new CT scans and MRI on abdomen/pelvis right after Thanksgiving. I pray that everythig is shrinking or at least staying stable. Prayers are needed .This is always such a stressful time for me since as you know, I am running out options. I willl update you on my results when I get them. By the way, my latest MRI on brain met 3 weeks ago showed that my brain met is stable. Thank God! The neurosurgeon believes that what I have is brain necrosis, more than active cancer on brain due to Gamma Knife on same site twice. Take care and God bless you all.
