Blood in stool

Greetings to everyone,

The issue at hand is this:

An individual over the age of 60 has been experiencing intermittent traces of blood in their stool for several months now. The amount fluctuates—sometimes more, sometimes less—but the blood is always bright red rather than dark or tarry. Aside from this and some bloating, there aren't any other symptoms. Occasionally, they feel a sudden urge to use the restroom, but it turns out to be just passing gas accompanied by a bit of blood. Other times, everything seems perfectly fine for days on end. There is no abdominal pain and no discomfort during bowel movements.
We suspect certain foods might be a trigger—definitely dairy and pineapple, perhaps cherries, and possibly even just the sheer volume of food consumed. They haven't experienced any significant weight loss, though they have dropped a few pounds due to eating less.
For context, they are a cardiac patient who has undergone surgery. Their current regimen includes aspirin and blood pressure medication.

Given the current public health situation and restrictions, getting an appointment with a doctor isn't easy right now. That is why I am turning to this community for insight.

Does anyone have any thoughts or perspectives to share?
Aside from the obvious "GET TO AN EMERGENCY ROOM IMMEDIATELY" advice, 🙂

Thank you.

I mean, you could probably just call a doctor at this point. So, we're talking occasional bleeding?

He went to see his primary care physician, who basically told him not to sweat it—just hemorrhoids—and mentioned she’d provide a referral if he felt it was truly necessary. But with the recent spike in COVID cases here in the States, he’s understandably hesitant to risk heading into a clinic or hospital, especially given his history with heart disease. One shouldn't shy away from medical advice, though; if it becomes essential, he'll have to face that fear eventually, no matter how much it unnerves him.

It fluctuates, you know? Sometimes there might be a little bit for a couple of days in a row, and then nothing for a week, only for it to resurface again.
His diet is where things really fall apart, which is arguably the biggest issue. For instance, he overindulged in spicy food quite a bit yesterday and the day before, and by last night, he ended up needing to use the restroom three times, all accompanied by that bleeding. Everything seems fine today, but currently, he's eating like a bird🙂 out of sheer anxiety.
