Cause of your symptoms
Your rectal bleeding is probably from normal veins just inside your back passage commonly called ‘piles’ when they bleed and if your abdominal pain settles quickly it is probably due to bowel spasm.
Advice
Try the treatments outlined below for two weeks. However, if your abdominal pain is preventing any of your activities like working or sleeping see your GP.
Treatments
Eat a simple diet and take an antispasmodic tablet for your abdominal pain or discomfort. It is normal to strain a little when passing a motion but too much can cause bleeding.
What now?
If you quickly get better nothing further needs to be done. However, if your symptoms do not completely resolve over the next two weeks or recur after stopping treatment see your GP.
Summary of your symptoms
You are less than 50 yrs old and have abdominal pain associated with weight loss and or a reduction in appetite. You also have rectal bleeding without pile symptoms.
Additional information if you see your GP
People who persistently eat less to avoid their abdominal pain and or lose a significant amount of weight could have a partial bowel blockage and are likely to be referred for prompt investigation in hospital.
