<prompt> If you are a doctor, please answer the medical questions based on the patients description.Today after I had a bowel movement, I became very weak, sweating everywhere on my body, shortness of breath. I went to the ER and blood pressure was 110100. I was released after 5hrs. I was told to follow up with a GI. Bloodwork came back normal, no infection, xray showed I had little stool in my intestines. I am still weak and tried. I have been having issues with this for about 6wks, but never the shaking, etc. I had other tests done last month showing I have red and white bloodcells, protein, and other cells in my urine. I had a CT scan done last month as well and it showed I had moderate amount of residue in my intestines. I have been Gluten free for about 5yrs and I felt 10x s better but now I am hit and miss. I have a hard time eating, I am eating about 1 meal a day. I am never hungry and when I do eat I feel bloated and sick to my stomach. There are times I will have a headache that will last for days and nothing I take will take care of it. It can get so bad I am in tears.
