On florinef x 6years for hypotension. i always had salt cravings & handfuls daily to keep bp up. still had low serum sodium. for the past few weeks this all stopped. i no longer crave salt-and stopped the handfuls but im retaining weight. causes?

Your type of low blood pressure tends to resolve over time. I suspect this is what happened to you. Now you're entering a phase of salt and water retention probably due to hormonal changes.If your MD agrees,avoid adding salt at the table and avoid obviously salty foods. A mild diuretic as needed may be prescribed if obvious bloating occurs. Weight reduction would help as fat tissue collects fluid.

You are not craved for salt anymore when volume is normalized and now you have extra volume which results in leg edema and I expect your serum sodium still remains low if checking at this time. You need to cut down 20-30% of fluid intake and the edema should resolve in 10-14 days, serum sodium should also improve by then.
