If I have a Sulfa allergy. Can I drink the bowel prep Suprep or Prepopick for a colonoscopy

My father is 78 years old and has been suffering from constipation for the last 2 years. He has also lost a lot of weight around 10 kgs in this time span. In the last couple of months he has been complaining that his abdominal muscles have torn due to bowel straining and now he says there is loss of muscle in his stomach area. Which is why when he lies down everything is fine but when he sits up and walks around he feels like he is carrying a weight in his stomach. After intake of food it becomes worse and he also gets bloating. We have done all possible tests - colonoscopy, CT scan, ultrasound sometime last year and everything was clear. The doctors gave a verdict of idiopathic constipation and left it at that. His blood work is fine, haemoglobin levels, cholestrol etc. He still suffers from constipation. His prostrate is enlarged but results are fine. What is the solution to his stomach muscle problem ? Is it lack of exercise, lack of protein ? He doesnt have a pot belly and has never had and had always been physically active and fairly slender.

I have had yellow mucus bowel movements and now have stool covered in a white film. what does this mean?

I have had amenerhea after the pill and had not had a period since last April (9 months ago). My OB put me on progesterone to induce withdrawal bleed and is likely going to diagnose PCOS. She is supposed to call today but first labs showed a Fsh:lh of over 3:1 so it looks like PCOS. I am having a very painful withdrawal bleed on this progesterone. Started with right side pain, constant ache in pelvic region now, and pain during bowel movements/urination? Does this sound normal for a progesterone withdrawal bleed?

I have normal bowel movements but constant green stools
