Brief Answer:
She need immediate evaluation.

Detailed Answer:
Hi,

Thanks for your question.
Noted your concern.

If your mother in law is not diabetic before, she should consult diabetologist at earliest.
In that case there is a need for
- Detailed clinical evaluation.
- Investigations like
Complete blood count
Renal function test
Liver function test
HbA1c
Urine examination including urine ketone.
Depending upon clinical examination & test results appropriate management can be planned.

If she is already on treatment for diabetes she need modification in treatment depending upon her clinical examination and prior medical evaluation.

Hope this helps.

Regards,
Dr Abhay Mali.
Diabetologist.
