Hello, everyone. I'm 22 years old but I'm definitely not feeling like it.. at a certain point after feeling like crap every day, I asked my doctor to order some labs. She tested just about everything from hypogonadism to hyperparathyroidism but has not found a diagnosis. Upon coming across an article about POTs and reading the insightful posts here I'm beginning to wonder if I should suggest to her that perhaps it is some form of dysautonomia? I mean, is there some kind of test (norepinephrine) that, if it were off, would force her to admit something dysautonomia-related was going on? Here are the symptoms that make me suspect it: -My blood pressure from yesterday: ( sit ) (stand) 11:00:104/52 63bpm / 83/51 97bpm 1:00 109/50 60bpm / 103/44 75bpm 2:30 110/54 64bpm / 98/48 87 bpm 3:00 115/46 55 bpm / 84/49 82 bpm 7:20 117/50 69bpm / 112/43 84bpm 9:00 110/49 65bpm / 102/45 75 bpm I do not suffer from fainting, however I do sometimes unexpectedly stumble or lose my balance when walking or standing from what I would attribute to lightheadedness. -Lifelong essential tremor and chronic nervousness that multiple SSRIs have not brought any relief to whatsoever. I feel like my *** cheeks (figuratively speaking) are more clenched than I realize because I've forgotten what it means to be completely relaxed. Very bad temper and extreme mood swings as a child (still bad to an extent) -Exercise intolerance - Poor stamina. When running at a distance most would find comfortable at a certain pace, I start to get lightheaded and I have to stop or I pass out. -I know this doesn't necessarily mean I have polydipsia, but people are always in awe at how much water I'm able to drink and so quickly. As it relates to hypovolemia, I do have high albumin levels even though I drink a lot. I do have salt cravings as well. -Fatigue - I feel like I just can't get through my day without a nap most of the time. When this urge comes on my BP is pretty low. I feel very zoned out all the time, thinking is slow and I never feel like I'm 100% there. -Coarse/dry hair, hair loss: Appeared about 3 years ago, has gotten worse. Hair used to be very soft, fluffy, oily, curly; now it's dry, weak, thin, and full of dandruff. Hypothyroidism and other diseases have been ruled out, if dysautonomia is indeed the culprit perhaps inadequate blood supply to head is causing this? Also, oral temp of 97.4. -Not sure if relevant, but stretch marks on inner thigh I got when I was 11 yrs old even though I was a very skinny kid. Help would be much appreciated.. I'd just like to know how I should proceed with my doctor. She is pretty open-minded and understanding.
