Hi, many thanks for the query!
Bright red blood in stools is suggesting "Haemorrhoides" if associated with pain in anal region on/during defaecation: External haemorrhoides or also anal fissure
if no pain then internal haemorrhoides.
No need to rush to ER unless there is severe ongoing bleeding.
Per Rectal Examination
& Proctoscopy is a must for diagnosis, to be done by a general surgeon
Take anti-spasmodics for abdominal pain
Do blood examination for Haemoglobin.
Appropriate management of the haemorrhoides as per their degree to be done by a general surgeon, once diagnosis is confirmed & Hb correction if deranged.
Do tests to rule out Lactose intolerance
, infective etiology, parasitic infestation.
Eat high-fibre diet, green leafy vegetables, stool softners, do meditation & yoga.
Wish you a good health. Take care.
