It sounds like you have IBS-A which is IBS that alternates between constipation and diarrhea. You need to convince your family that you need to see a doctor, specifically a gastroenterologist to get some testing done to make sure it isn't more serious.
well all day there is no set time. and it isnt occasional diarrhea its a lot and then there are times when im backed up so bad i dont crap for a while and then i take a laxative and i dont feel it does the trick all the way.
when i havent crapped in weeks that happens too by the way i get completely backed up for ages even with fiber
Welcome to the gastroenterology community! Why would you take a laxative if you are already having diarrhea? How long has the diarrhea been going on for?
Instead of talking about what you THINK it is and how your family feels you need to elaborate on your symtoms a little bit more. You said you have stomach aches and occasional diarrhea it sounds like. Are there any other symptoms? When does the stomach pain and diarrhea happen after you eat a meal? In morning only? Night only? All day? I totally understand how it feels when a family blows off your complaints of sickness and in my experience, the family turned out WRONG! But you gotta help us help you by giving more details about what you're feeling.
i also have 3 cats and a dog at my house the cats are about 2 years old and the dog and third cat are both less than 5 months old
