I went for several years after my gastric bypass with complications that no one seemed to be able to diagnose. I was told everything from being anorexic, it was all in my head and even got a lot of I have no idea so here's a pill.
My new doctor discovered that my body is not able to absorb vitamin D, so I am taking mega doses (50,000 units) per week. Normal levels of D are about 20-100, 20 being low. My level is only 8. The complications from this deficiency may be irreversible because it went undetected for a few years.
My symptoms include: muscle weakness, nausea, vomiting, tremors, seizures, sensory neuropathy (my hands, feet and face are kind of numb), osteoporosis, loss of teeth due to weakness, terrible pain everywhere (the worst is my abdomen and back), and I am starting to have renal failure.
My muscles are so weak at this point that I have great difficulty doing even the smallest things like getting dressed or taking a shower.
Anyone who has had gastric bypass surgery or is considering it needs to be aware of this. It is very scary and I am not sure if it will cause me to die at an earlier age as some anorexic people do.
