### input:
My husband recently was hospitalized due to renal failure. He was there for 2 weeks running all types of tests. He returned home with the doctors still not knowing what exactly was wrong. At this point  they ruled out the failure part although his kidneys are not putting out the way they should they are still functioning. He returned to ER 3 days after being released due to vomiting. They stablized it and sent him home again. Now he has no appitite and most times cannot even keep down water. I try not to let him take his medication unless he eats, which he does not, so he is not taking his meds. We went to his doctor yesterday where they determined he was dehydrated so they put him on a IV for 3 hours. We left the hospital stopped for bottled water where he then vomited again. Is there something he can take to maybe coat his stomach to help keep things down?

### output:

Hello, As per your description your husband is suffering from some kidney disease. But its unclear whether it is Acute Kidney Injury(AKA) or Chronic Kidney disease(CKD). Because AKA is temporary and more serious than CKD. But vomiting is a very common condition in any disease. In kidney diseases, recurrent vomiting are common due to Uremia(increase serum urea). This will also lead to loss of appetite. In your case, you have to find out the extent of kidney damage and cause of vomiting by some tests like USG abdomen pelvis, KFT and ABG with Serum Phosphoric level. Meanwhile, better get admitted the patient and start IVF with washout urea if increased. As much as put on more injectables rather than oral. So don't be panic and evaluate the patient properly and treat with injections for few days and get down serum urea level if increased by diuretics or dialysis if needed. Thank you
