[|Human|] Hi. My father is the patient. he s 80 yrs old and had a stroke 5 months ago-he was diagnosed with an ischaemic stroke. Comorbidities are: hypertension, diabetes mellitus and prostate cancer. he s currently discharged from the hospital. he s been having very high blood pressures at night like 194/90 and during the day, especially when we sit him down, it falls so low like 90/70 for about a month now. he also started having seizures some weeks ago, about once a week and now, for the past two days, he s been vomitting. his urine is also highly concentrated and sometimes in a day, urine output is less than 100mls. his appetite has also declined and he s lethargic with lots of hiccups. can you please tell me what is happening?
[|AI|]  Hi, Low urine output and hiccups, vomiting suggest uremia/renal failure; need to know BUN, serum creatinine, serum electrolytes and urinalysis report apart from full blood count. He is also having postural hypotension from lying to sitting position (lying to standing -more sensitive but lying to sitting is sometimes all that is possible for a less mobile patient).  Prolonged bed rest and chronic hypertension (decreased barreled sensitivity and LV compliance) and?  Chat Doctor.  He may require renal replacement therapy. Hope I have answered your query. Let me know if I can assist you further.
