I am 60 year old male and I've been experiencing gastrointestinal problems for 6-7 years. Body intolerance for foods has reduced my diet to 3-4 food items, like curd, tomato, spinach, bread, other than which i cannot eat anything. Inspite of this super restricted diet, digestive system behaves abnormally. After every 2-3 days there is cramping, very uneasy feeling, weekness and diarrhea, seems like there is no end to this.
