Hi thanks for asking question. You have not mentioned cause of dysentery. It may be bacterial or amebic dysentery.stool examination done if it shoes pus cells with RBC then bacterial cause.Antibiotic needed for it. If eggs seen then ameba is the cause .metronidazole given for it. Meanwhile whenever you have dysentery take following measures... More water. More fruits. Green leafy vegetable taken more. Avoid meat and heavy fatty and fried meal. Cooked oatmeal good in soothing inflamed area. Avoid excess spicy food. Maintain hydration and avoid stress. If still your symptoms increasing then colonoscopy done with subsequent biopsy to rule out inflammatory bowel diasease or microscopic colitis like conditions. I hope your concern solved. Take care.
