Anyone with POTS have issues with muscle mass?

Kittenbusiness

Has anyone here been diagnosed with POTS? I was diagnosed last year and was told I have low muscle mass as a result. My cardiologist put me on a high sodium diet (aim for 7000 mg a day) and to eat 3k calories per day. I have been weighing all my food and logging it for him, yet haven't gained muscle mass. Was wondering if anyone with this issue found something that works for them? I'm 5'6 122 pounds. Thanks

Yes, I have been heavy lifting and doing insanity. I just finished month 1 of insanity.
