Thanks for posting your query.
Your query suggest that your mother is suffering from renal failure
, most likely chronic.
, patient may have deranged renal function test with multiple organ symptoms.
Such cases are labeled as "Uremia".
You should consult with internal medicine specialist/ nephrologist
and follow all dietary restricitons as suggested by your treating doctors.
Her renal function test must be in controlled range and all efforts should be made.
This is the only way by all these uremic symptoms gets controlled.
