Hi my sister woke up with stomach pains and tried to poop but nothing came out. so she went back to bed and an hour later she went back to the bathroom cause she couldnt take the pain anymore and had to try again and when she finally pooped she threw up also. now shes in bed with the same stomach pains and throwing up still.  any idea what this could be?
Hi. Thanks for your query. The history of your sister is typical, tried to poop but could not; and when she could, she vomited also and still throwing up. This is possible that she has severe constipation and when she could poop with force the vomiting started as a reflex mechanism or the first vomiting caused the esophagitis allowing her to have more vomiting.
