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: penicillins / metformin attending: chief complaint: brbpr major surgical or invasive procedure: upper endoscopy (egd) colonoscopy history of present illness: hx per osh h&p. has history of previous gib 4 years ago with colonoscopy demonstrating diverticula in the colon as well as ?duod divertic. presented on to osh with maroon-colored stools and clots per rectum starting on and becoming more frequent on . the bowel movements were painless and he denied any abdominal pain. in the ed the patient felt dizzy and lightheaded. hct on admission was 37. after admission the patient continued to have bloody stools but was not symptomatic. his hct continued to fall with subsequent crits being 32 to 26. patient transfused 2 units prbc. after the crit remained at 26. received another 2 units. during this time the patient remained stable with normal heart rates and blood pressures. however he had another episode, but more significant, of blood per rectum. during that time the patient had a syncopal episode and was sent to the micu. received 2 more units of prbc. patient is being transferred to our micu for further workup including likely gi intervention vs. surgery. a ct scan from the osh showed extensive diverticulosis without any active extrav of the contrast. . on arrival to the micu, he is alert and oriented, hemodynamically stable and comfortably. . review of systems: (+) per hpi (-) denies fever, chills, night sweats, recent weight loss or gain. denies headache, sinus tenderness, rhinorrhea or congestion. denies cough, shortness of breath, or wheezing. denies chest pain, chest pressure, palpitations, or weakness. denies nausea, vomiting, diarrhea, constipation, abdominal pain, or changes in bowel habits. denies dysuria, frequency, or urgency. denies arthralgias or myalgias. denies rashes or skin changes. past medical history: diabetes, hypertension, hyperlipidemia, gib, peripheral neuropathy, asthma social history: - tobacco: remote history but no current - alcohol: social - illicits: denies family history: family hx of crohns disease physical exam: admission exam: vitals: t:98.4 bp:152/70 p:78 r: 18 o2:98 general: alert, oriented, no acute distress heent: sclera anicteric, mmm, oropharynx clear, eomi, perrl neck: supple, jvp not elevated, no lad cv: regular rate and rhythm, normal s1 + s2, no murmurs, rubs, gallops lungs: expiratory wheeze present more on l than r, no wheezes, rales, ronchi abdomen: soft, non-tender, non-distended, bowel sounds present, no organomegaly gu: no foley ext: warm, well perfused, 2+ pulses, no clubbing, cyanosis or edema, venous stasis changes present b/l neuro: cnii-xii intact, 5/5 strength upper/lower extremities, grossly normal sensation, 2+ reflexes bilaterally, gait deferred, finger-to-nose intact discharge exam: gen: nad, breathing comfortably cv: s1 and s2, regular, no murmur pulm: lungs cta throughout abd: nondistended, (+)bowel sounds, no tenderness to superficial or deep palpation neuro: gait normal - steady ambulating down hallway pertinent results: admission labs: 12:20am blood wbc-9.8 rbc-2.88* hgb-9.1* hct-25.1* mcv-87 mch-31.7 mchc-36.4* rdw-17.6* plt ct-121* 12:20am blood neuts-74.6* lymphs-15.3* monos-5.0 eos-4.6* baso-0.4 12:20am blood pt-11.8 ptt-25.6 inr(pt)-1.1 12:20am blood glucose-141* urean-16 creat-0.9 na-144 k-3.8 cl-111* hco3-27 angap-10 12:20am blood calcium-7.2* phos-2.3* mg-1.9 12:24am blood type- temp-36.8 ph-7.36 12:24am blood freeca-1.08* discharge labs: 07:05am blood wbc-7.9 rbc-2.94* hgb-9.3* hct-26.5* mcv-90 mch-31.6 mchc-35.1* rdw-17.9* plt ct-163 06:44am blood glucose-117* urean-10 creat-0.8 na-142 k-3.4 cl-108 hco3-28 angap-9 03:51am blood calcium-7.7* phos-3.0 mg-2.4 hematocrit trend 25.1 --> transfused 2u prbc 27.4 27.5 28.2 26.3 26.3 25.7 26.5 24.7 26.5 ekg sinus rhythm with non-diagnostic t wave flattening. no previous tracing available for comparison. cta abdomen and pelvis 1. no evidence of active gastrointestinal bleeding. 2. infrarenal abdominal aortic aneurysm maximally measuring 5.5 cm. 3. bilateral simple renal cortical cysts. 4. extensive colonic diverticulosis, without evidence of acute diverticulitis. egd esophagitis friability and erythema in the whole stomach compatible with gastritis friability and erythema in the duodenal bulb compatible with duodenitis diverticulum in the fourth part of the duodenum there was no blood or evidence of recent bleeding in the upper gi tract to the ligament of treitz.. otherwise normal egd to distal duodenum colonoscopy diverticulosis from 15 cm to the splenic flexure; diverticulae in the ascending colon blood in the colon otherwise normal colonoscopy to terminal ileum brief hospital course: mr. is an 80y/o gentleman with htn, dm2, and prior diverticular bleed who was transferred from an osh with lower gi bleed. he was stabilized in the micu and then transferred to the floor. workup (cta, egd, colonoscopy, tagged rbc scan) were unable to localize the exact site, but it is likely that the bleed was diverticular. prior to discharge home, his hct was stable and he had not had any more bleeding for >24 hours. he will follow up with his pcp and gastroenterologist. active issues #. lgib: likely diverticular, though no site of bleed seen. he had received 7 units prbcs at the osh, and he required 2 more units here (please see "hct trend" above. he passed bright blood and clots (~300cc at a time) about every 12 hours, but always remained hemodynamically stable. cta, egd, colonoscopy, tagged rbc scan were performed and confirmed his known diverticulosis but no active site of bleed was seen. after transfer to the medical floor, his bleeding gradually stopped and his hct stabilized (was 26.5 at the time of discharge). he had no bleeding for >24 hours; his diet was advanced and he was discharged home. he will follow up with his pcp and an appointment was made with a gastroenterologist of his choice. during his stay, he was followed by gi and surgery - in the long run, he will benefit from continued discussions about the risks and benefits of colectomy for his diverticular disease. #. gastritis on egd: incidental finding. no complaints of reflux/heartburn but he was found to have gastritis on egd. biopsies were not taken due to ongoing gi bleed. he should have outpatient h. pylori serology testing. he was started on a ppi due to the evidence of gastritis (though if he continues to experience no symptoms, this could possibly be discontinued). #. 5.5cm infrarenal aaa on cta: incidental finding. per patient, he is aware of this. he was advised to follow up with his pcp for ongoing monitoring/possible intervention. inactive issues #. htn: stable. his antihypertensives were initially held in the setting of gi bleed. throughout his stay he was hemodynamically stable (in fact, hypertensive to sbp 160). his home meds were restarted and his blood pressures were controlled. he will continue on norvasc and lisinopril. #. hyperlipidemia: stable. he was continued on lipitor. #. dm2: stable. his prandin was held in-house and he was covered with ssi humalog. he was discharged on prandin and will follow up with his pcp. #. asthma: stable. he was continued on advair. transitional issues #. code: full code #. emergency contact: (wife) #. labs/studies pending at the time of discharge: none #. issues requiring follow-up: -aaa (see above) -needs outpatient h. pylori testing (see above) -ongoing discussion regarding risks/benefits of colectomy for diverticular disease medications on admission: norvasc 5mg qd lipitor 20mg qhs lisinopril 20mg qd advair diskus 100/50 inh prandin 4mg tid discharge medications: 1. norvasc 5 mg tablet sig: one (1) tablet po once a day. 2. lipitor 20 mg tablet sig: one (1) tablet po at bedtime. 3. lisinopril 20 mg tablet sig: one (1) tablet po daily (daily). 4. advair diskus 100-50 mcg/dose disk with device sig: one (1) puff inhalation twice a day. 5. prandin 2 mg tablet sig: two (2) tablet po three times a day. 6. omeprazole 20 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po daily (daily). disp:*30 capsule, delayed release(e.c.)(s)* refills:*2* discharge disposition: home discharge diagnosis: lower gastrointestinal bleed discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: you were transferred to because of gastrointestinal bleeding requiring 7 units of blood. initially you were admitted to the icu, where you received 2 more units of blood and became stable so you were transferred to the medical floor. while you were here, you underwent various studies to evaluate for a cause of the bleed (upper endoscopy, colonoscopy, ct angiogram, tagged red blood cell scan) but no definitive site of bleed was found. it is most likely that you had a bleed from colonic diverticuli, which you have had in the past. now you are stable for discharge home with primary care and gastroenterology follow-up. please note that on one of your ct scans showed a aaa (abdominal aortic aneurysm), which is a dilation of the major blood vessel that carries blood away from the heart. the size was 5.5cm (normal is less than 3cm). please follow up with your primary care doctor regarding further management (such as surgical repair). we made the following changes to your medications: -start omeprazole (an anti-acid pill because of "gastritis," inflammation which was seen in the stomach during your upper endoscopy) followup instructions: primary care name: , np (works with dr location: medical associates -internal med address: 28 dr, , phone: appt: at 11:30am gastroenterology name: , address: # 5, , ma phone: appt: at 9:45am ***this appt is in his office and the first available he had in any of his offices. office recommended also calling occasionally for cancellations. please call the office with questions. procedure: other endoscopy of small intestine colonoscopy diagnoses: thrombocytopenia, unspecified unspecified essential hypertension acute posthemorrhagic anemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled asthma, unspecified type, unspecified personal history of tobacco use other and unspecified hyperlipidemia duodenitis, without mention of hemorrhage abdominal aneurysm without mention of rupture esophagitis, unspecified unspecified hereditary and idiopathic peripheral neuropathy diverticulosis of colon with hemorrhage unspecified gastritis and gastroduodenitis, without mention of hemorrhage
