A year ago I bled a fair bit from my back end. Six months later it happened again so I went to a medico who urged me to get a colonoscopy. Before then I'd begun every dawn with a leak followed by eating a quarter lemon washed down with 300/500 ml of water & going back to bed for a couple of hours. Likewise doing the same every night at bedtime on a near empty stomach. Had the colonoscopy. Result? Bleeding piles. A written prognosis from the surgeon was for me to come back in ten years - when I'm 78, such was mint condition of my lower canal. Lemons - they keep things clean.
