Unhappy with treatment my mom got from Dr T Viljoen

On 07 May, mom went to Dr T Viljoen, had flu symptoms and stomach pain. Notified me on 08 & 09 May that her stomach must settle.

07 June and 11 June back to Dr Viljoen for stomach pain and vomiting, also complained about constipation.

So on 07 June (after a month, stomach issue still not resolved) and 11 June (4 days from 07 June, stomach issue still not resolved).

Based on above, why did the doctor not refer my mom for to a hospital.

...............

On 12 June mom diagnosed with colon perforation.

Colon compacted with faeces, if you view the below section of above webpage, Management and Treatment How is fecal impaction treated?

Enema did not work. Laxatives did not work (enema).

So 2 options left Physical assisted removal. Surgery.
