Jedi Jedi depends on what it is. Home remedies can be commenced even before presentation at the hospital for example in diarrhoea illness.

If it's Diarrhoea, all you just need is Oral Rehydration Solution (ORS) and oral Zinc.
If it's Dysentery, you will need antibiotics. So see a doctor.
Haemorrhoids and rectal prolapse may require surgery depending on the severity. They can also be managed conservatively.
