Dear Amy,
Regarding the weight gain - I have certainly gained weight gradually over the past several years, and I have been diagnosed with SCLS, but I think the weight gain is more of a byproduct of my much decreased activity. Since hot weather, exertion, even stress can aggravate my swelling, especially in the ankles and feet and lower legs and abdomen, I go to great lengths to avoid all of the above. This is a huge change in my lifestyle, and therefore I've gained weight. Sure, there have been times when I've gained 10 pounds and lost 10 pounds in a week's time during flareups, but the kind of weight you're talking about is likely due to the change in your lifestyle, which is absolutely understandable and in that way, related to your diagnosis. I would think that the earlier you're diagnosed, the less overall weight you would gain as a result of having any chronic illness. Once you have found a doctor and a proper treatment for any illness hopefully one can resume close to their prior activity level. Likewise if you go years without any answers, without any guidance or treatment, and quite probably living with a certain amount of day-to-day fear, there's just no way your activity level isn't going to be altered. As far as cravings go, yeah, sometimes I crave salty food, and I think that has to do with the sodium levels in my blood related to how much edema is present. And I also use caffeine. Even though I shouldn't.I can relate to a lot of the symptoms that you described. Good luck to you and I hope you get the appropriate treatment soon.
