Can it provoke digestive problems the ingestion of aluminum foil?

How big of a chunk?

Here are a couple of references.

Assuming it was a small piece of kitchen foil I would say there is little danger of the foil casuing any damage to the GI tract. In @Cupcake‘s second reference the aluminum foil was part of a drug blister pack and looks as though the backing was plastic cut to a sharp angle which I suspect caused the damage.

If you are worried speak to your doctor or go to an ER.

How did it taste?

There is a term with livestock called ‘hardware disease.’ lol

Geese, goats,horses and other creatures eating metallic trash ( by accident usually )...such as nails, bits of wire, etc.

I suggest a gallon of minerel oil intubated via your nostrils…might help…hahahahahaha

I would think you will pass it with the rest of the remains of the food you ate that day.

Yes. It can cause a bowel obstruction if it’s big.

I also ate a small piece of foil and it caused intestinal perforation, very painful. The pain lasted for days, then I had to have surgery to remove the piece of foil. So, yeah it can be very bad.
