Question: On February 1 I had a TKR. On February 13 I got very sick, nausea, diarrhea, vomiting with a low grade fever. Went to my PCP, treated for a gastrointestinal disorder. On February 16 I ended up in the ER. Fluids, blood work, urine. Lab indicated potassium deficiency had fluids . pA said she did not think I had an obstruction and she felt like it was my gut flora had been stripped from all the antibiotics and pain medication from the surgery. Here it is March 5 and I’m still sick.

Brief Answer:
Stool analysis.

Detailed Answer:


I have gone through your question and I understand your concerns but I would recommend that you get a stool analysis as gastroenteritis is not necessary due to bacterial infection. It can occur commonly due to protozoal infection which needs specific treatment rather than antibiotics to be cured potassium deficiency is probably due to diarrhea which leads to increased excretion of potassium in stools.

I agree with your doctor that antibiotics could eliminate the normal intestinal flora which can be regained by the use of probiotics.

I hope you find this helpful.
