Hypothetically would it hurt to take 4 ibuprofens at once?

Oh yes and I will tell you the story about my niece and her taking Ibuprofens every day for her pains. She was about 18 years old and was having some pains in her body. She was stressed and tired from going to college plus several part-time jobs. When she was a freshman in college she went to a doctor due to not having a bowel movement for nearly a week. They scanned her and found that she had an impacted mass in her intestines and decided to do emergency surgery, removing 8 inches of intestine along with the impacted stools. She said the ibuprofens she had been taking had eroded her digestive lining and caused her bowel to stretch in that one spot accumulating the mass that refused to budge. And she was told to go on a gluten-free diet for a year so her gut lining could heal. Ibuprofens are so harsh on the stomach that they can potentially cause a bleeding stomach ulcer. Taking four at a time is dangerous

I was not able use them for painkillers due to having a sensitive digestion system. Took one for muscle pain at work after eating breakfast and doubled up in pain for a long time. It would be dangerous for me to use them, aspirin (which used to cause me to vomit) and was told by a dental surgeon that even regular Tylenol usage could cause gut problems eventually.
