Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: cc: major surgical or invasive procedure: angior procedure with no localized source of bleed colonoscopy showed multiple diverticula and fresh blood but no source of bleed history of present illness: hpi: 80 m w/ pmhx of dm ii and transferred from osh b/o brbpr. pt presented to osh with brbpr. per his family he had been c/o some abdominal discomfort for several weeks. over this last weekend he had a decreased appetite and appeared more pale and tired. he began having brbpr on the night of and presented to the osh the next am. . in osh, his hct dropped from 31 -->25 (baseline ~ 38). he received 2 u prbc transfusions. his bleeding persisted in small amounts and then he put out 200 cc of blood at 3 pm and 300 cc at 6:30 pm on . a tagged rbc scan on revealed bleeding in the mid to distal descending colon. he was not scoped at that time. he was transferred to micu for further management. . also pt has some l shoulder pain from a recent fall at home. past medical history: htn niddm mental retardation s/p illness as a child no prior h/o gi bleeds social history: lives with his brother and sister-in-law. is fairly independent. his sister-in-law is his hcp. has no h/o etoh, tobacco or drug use per his sister-in-law family history: father died of mi in his 60s mother died at 94, had dm no family h/o cancer of gi bleeds physical exam: vs tc 98.4 hr 75 bp 182/74 rr 21 o2 sat 95% ra gen: thin, elderly male in nad heent: normocephalic, anicteric sclera, dry mmm neck: no

ph-7.38 calhco3-18* base xs--6 intubat-not intuba . angio : impression: selective and superselective celiac, sma, arteriograms demonstrated no active bleeding. no intervention was performed. . colonoscopy : there was blood throughout colon but given fresh blood seen in the sigmoid colon the source of the bleed is most likely a left sided diverticulum. continue to follow serial hcts and transfuse for goal hct> 30 if bleeding continues will need to consider l hemicolectomy. if bleeding becomes brisk would do repeat angiography . tagged rbc scan : impression: no active gi bleeding at the time of study brief hospital course: a/p: 80 m w h/o dm, htn who p/w brbpr, likely to diverticula with no source identified on colonoscopy or angio. . * gib: the patient started having brbpr on . tagged rbc scan at osh showed bleeding in the distal colon and his hct trended down from 30 to 25 there per report. he was transfused two units of prbcs and transferred here. upon arrival patient was hemodynamically stable, with stable hct. overnight he started having melena and his hct began to trend down. he was urgently taken to angiography, but no mesenteric source of bleed was identified. on he had a colonoscopy which showed multiple diverticula, which were thought to be the source of bleeding, but the source of the bleed was not able to be identified. the patient continued to have melanotic stools and required a total of ~ 10 units of prbcs over 4-5 days. surgery was consulted and intially were going to perform a left hemicolectomy. a tagged rbc scan was done to help dilineate where the bleeding was, but the scan did not show a source for bleeding. an abdominal ct was also done to r/o rp bleed, after angio in the setting of dropping hcts. the ct was negative for bleed. the patient stopped having melanotic stools on , so he was not taken to surgery. his hct remained stable and he did not require further transfusions, and was subsequently transferred to the floor. while on the floor, the patient required no further transfusions. his diet was advacned to a regular diet. his hematocrit remained stable. . *htn: the patient had a histpry of htn and sbps during his admission here were as high as 190s. his bp meds were initially held b/c of concern for bleeding. however, his pressures were significantly elevated, so he was started on a small dose of an acei. when his bleeding stopped his acei was uptitrated and a bb was added to his regimen, with better control of his pressures. he was also treated with prn hydralazine. while on the floor the patient's blood pressure was stable on captopril and lopressor. he is to be discharged on an approximately equivalent dose of toprol and lisinopril. . * dm: the patient has a history of dm. his oral hypoglycemics were held at admission and he was covered with a riss and had qid fs. fingersticks had been stable, but started to rise when he started tpn. the insulin in his tpn was increased at that time. after transfer to the floor the patient's tpn was discontinued as he was able to tolerate a regular diet. his home oral hypoglycemics were started the day prior to discharge. . *thrombocytopenia: the patient's plts trended down initially during his admission this was thought to be dilutional. his platelets slowly began to trend up during his stay and remained stable. . * f/e/n: the patient received ivf when he was actively bleeding and was kept npo. he was started on tpn on . he was advanced to a clear liquid diet on . his tpn was discontinued as he was able to tolerate a regular diet. . * ppx: the patient was placed on pneumoboots. initially he was on no bowel regimen because of active bleed. docusate was added because of constipation. though initially on a ppi, this was discontinued because no evidence of ugi bleed. . * code status: full . * comm: communication was kept with the patient's sister-in law- . her husband was contact for all necessary consents. medications on admission: avandia 8 mg qd, lisinopril 5 mg qd, glipizide 10 mg qd, metformin 1000 mg qam - 500 mg qpm, plendil 5 mg qd discharge disposition: extended care facility: & rehab center - discharge diagnosis: diverticular bleed hypertension non-sustained ventricular tachycardia non-insulin dependent diabetes mellitus discharge condition: good. the patient's hematocrit has been stable. discharge instructions: please take all medications as directed. please follow-up with dr. as below. the patient's caregivers should contact dr. or bring the patient to the emergency room if he
