My husband had recently underwent a colonoscopy. He, unfortunately wound up in the hospital ER, the next day, with bloating and diarreha. He was also severly dehyrated and his kidneys took a direct hit as a result. I should state that the previous year, he had to have his right colon removed, due to cancer, which was caught early, hence no treatments, but he had a resection. It was his left colon that had the latest testing. I guess there was no place for the gas, that was injected to see the colon properly, didn t have a place to go, hence the bloating and diarrhea. It had blood work and a IV given, and two shots for the nausea. We were then sent home and had no more gotten home when he became quite ill, vomiting and diarrhea. He then felt better, but was having diarrhea every hour all night long. We went back to the ER the next day, afternoon, where they did more blood testing and more IV. The IV went out his bowel as soon as they were given. He had diarrhea pretty severe. He was then admitted to the hospital for overnight, so they could give him more IV s and keep an eye on his diarrhea and kidney functions. I guess what I want to know is what a lot of the blood testing means. He had CBC with Auto Differential, which was showed abnormal. He will be seeing his own physician in 4 days with more blood work. His bands was 26.0, moncytes 22.0, monocytes 2.06, glucose 122, bun 59, creatine, blood 1.67, bun/creatine 35, and t bili 4.8, all considered high, the low ones were neutrophils 38.0, lymphocytes 10.0, sodium 133, co2, venous 18, gfr, est. 40, and gfr, est. african 48. Thank you for a second opinion.
