Abdominal pain can be caused by many conditions. However, the main causes are infection, abnormal growths, inflammation, obstruction (blockage), and intestinal disorders. Infections in the throat, intestines, and blood can cause bacteria to enter your digestive tract, resulting in abdominal pain.
Most obviously, a hyphen is used to indicate that a long word has been broken off at the end of a line: You should avoid such word splitting whenever possible. If it is unavoidable, try to split the word into two roughly equal parts, and make sure you split it at an obvious boundary. Do not write things like.
That's because punctuation rules say to use a hyphen to join two words that together modify a third word any time it can aid comprehension and readability. That's a tiny matter, of course. But little things add up. This sentence is technically fine.
