hickups

for the last month I have been having pickups at least 3 different times a day. I have not changed any part of my diet or lifestyle. I have a part-time job and eat when I can. I have also noticed I've been popping more than normal. For years I'd maybe poop once a month if I was lucky. Now I can poop up to 5 times a day. 3 of which was 30 minutes after eating. To top it all off its not a normal poop, it's diarrhea. Please help me find something out. Thank you in advance
