Hi everyone; I have not written in quite awhile. My question is about low sodium. My dad was diagnosed with limited stage sclc back in January. Before diagnosis, he had a low sodium level, finally they figured out it was sclc. The tumor is in his left lung and lymph nodes. The dr thought it was in the adrenal gland, but after he received chemo there was no change in the size of the adrenal gland, and dr. said it was not there. Went thru chemo, radiation to chest (x30) and proph. radiation to the brain. This finished up in early July. Dad was feeling pretty good, had gotten his strength back (not all but a good portion), and then starting in mid August we could tell that he was becoming more tired. An appt. with Dr. was scheduled for September 21st. Well within the last week and a half, headaches, weakness and not eating well. Brought him in early, sodium was 117. Was admitted to the hospital, sodium dropped to 115. They finally(!!) started him on fluids. Scans all came back fine. Nothing on the brain, no change in tumor size in lung, adrenal glands still same size. I guess my question is... with the low sodium, does this mean that the tumor is "active" again, and his the cancer traveling? Just worried, he is still in the hospital and they started him on a sodium pill (the name I am not sure of at this time), level has only gone up to 121 with the IV so hopefully the pill will kick in. I have read up on the low sodium in sclc, no real answers out there to answer my question. We will be discussing this with his dr., just wanted some input from this wonderful group. Thanks! As always, you are always in my thoughts and prayers!!
