Hello
Thanks for writing to us with your health concern.
Bright red blood after a BM could be due to the following possibilities -
1. Anal fissure - this is slight abrasion of the anal mucosa, typically leading to a reddish streak on the toilet seat after passing motions.
2. Haemorrhoids - these need not always be painful, external haemorrhoids often can be painless
3. Anal fistula .
The exact cause would be known only after examining you locally.
PLease get that done, meanwhile address constipation if that is an issue.
Taking mild laxatives is also fine.
ALso, take warm Sitz baths 4 - 5 times a day.
Anal fissue will respond to Local Lidocaine jelly.
Haemorrhoids need proper treatment as per the type.
PLease visit your doctor for a local examination.
Do not worry, as these are minor conditions , which are easily treatable.
All the best.
Please feel free to ask for further clarifications.
