Doctor, my grandmother is 80 years old and she was diagnosed with a rectal tumor 6 months ago. Now she is having problems with her bowel movement. She complains about feeling so much pain every time she defecates, and she has to take laxatives to help. Should my grandma undergo surgery in her old age? Could taking too much laxatives be dangerous for her?
Doctor, my father who is 50 years old, has had haemorrhoids since 4 years ago. It used to get better without taking any medication. But as time goes by, it keeps recurring again and again. His doctor suggested a surgery. Can it be totally cured by having surgery? Is there any chance of recurrence?
Doctor, I am 26 years old. These two weeks I spotted blood in my feces. Not everyday though, maybe 3 times a week. But it is without pain, not even in my stomach. Do I need to be worried and see a doctor?
Doctor, I have a 15 day old child. This morning when I gave him a bath, I noticed a hole above his anus. What is it, Doc?
Hello Doctor, I had a normal birth 6 months ago. This past week, I think there are dregs in my urine and they are as smelly as stool. I read online that it might be an anal fissure. Is there any chance I tore my anus when I gave birth so my urine is contaminated with stool? What should I do?
Doctor, I have been having haemorrhoids for these 2 years. It used to be cured by its own, but recently it hurts so bad, as if there is a piece of flesh stuck in my anus. Should I have surgery, or will herbal medicines help?
Doctor, my mother is 50. She complained that she can’t hold in her defecation when she coughs and laughs. Is this normal for someone who is 50?
Doctor, I am a 36 year old male and have anal fissure. I went for a surgery but it failed. What procedure should I undergo? I am not comfortable with this condition.
Doctor, I am 20 years old. Since I was in high school, there has been a lump in my anus and it has grown bigger now. That lump presses out when I defecate, and I have to push it back afterwards. It doesn’t hurt, but it bothers me. How to treat this, Doc?
