Sounds like you may have IBS (irritable bowel syndrome). Here is what I did that helped me.
I took several months researching the different foods that people with IBS found they could eat that helped their symptoms. Then using trial and error I began to cut things out of my diet to see if they gave me some relief. I kept records of everything I ate and every bowel movement and found out what helped and what caused problems. I started by cutting wheat and lactose out of my diet. There is a lot of information on the web and it takes time but you can figure out a diet that helps. One supplement that I take that helps is psyllium husk tablets. Prayer definitely helps. God bless you.
