Had quadruple bypass surgery. Is it normal to have upset stomach?

My mother had quadruple bypass surgery in March. Yesterday she had to have one of the new arteries(the main artery ) stented. I have two questions. First: Is it normal for her to have a very, very upset stomach today (and she is really pale)? She has no other issues aside from the severely upset stomach. Second: How does a new artery become blocked that quickly? She exercises every day, is super active and eats fairly healthy.

Thank you for your query. I can understand your concerns.
Upset of stomach may be due to aspirin which is usually given to prevent future blockade of coronary artery by thrombus (secondary prevention). Bed rest and the effect of the narcotics used for the relief of pain often lead to constipation. Hence cardiac patient are routinely given stool softener such as dioctyl sodium sulfosuccinate (200 mg/d) to reduce any extra strain during defecation.
Risk factors for restenosis after percutaneous transluminal coronary angioplasty are age (more common after 60 years of age), hemostatic variables like fibrinogen, imbalance in the prothrombotic-antithrombotic equilibrium prior to the procedure.
Drug-eluting stents have been shown to reduce clinical restenosis by 50% and are superior to bare-metal stents .
In-stent restenosis is typically seen 3 to 6 months after the procedure; after 12 months have passed uneventfully, it is rare.
Patients with diabetes are at increased risk for in-stent restenosis. Further important risk factors relate to the properties of the blocked artery and the pattern of scar tissue growth inside the artery; the more extensive the scar tissue growth, the worse the prognosis is.
