I had gastroenteritis when I was 13 years old and ever since my digestion has never been okay. There have been many digestive issues that I have faced but the majority of them are: indigestion (present from the start, frequency:high) loose stool (present from the start, frequency:high) constipation (present from the start, frequency:high) anal discomfort (started when I pressured to defecate, frequency:high) anal abscess (happened when I exercised to relieve constipation, frequency:just once) anal pain ((started when I pressured to defecate, frequency:low) blood from anus (bright red, frequency:very rare but has happened) incomplete defecation (from the start, frequency:high) acidity (started from 4 years ago) heat around stomach (started from 4 years ago) fatigue (present from the start) brain fog (present from the start) yellow greasy poop which burns on defecating (when I exercise to relieve constipation)
